VidyoClient API Binary Library: About Version 22.3.0

What's new in this release

Ability to set your application name and version using VidyoConnectorSetProductInfo
- Applications using the VidyoConnector API can now set their own application name and version when calling VidyoConnectorSetProductInfo.
  - If no application name is provided, "VidyoConnector" is used.
New VidyoRemoteCameraViscaControl API for controlling remote cameras
- This release introduces a new connector-level API for remote cameras: VidyoRemoteCameraViscaControl. In conferences where the remote camera is controlled over VISCA (such as with VidyoConnect Room), applications can now send VISCA commands to control the remote camera.
Updated CA certificates
- We've updated the ca-certificates in our code. These certificates are used by products that require a CA root certificate bundle.
- This update improves the compatibility of the certificates with the VidyoPortal, web browsers, and mobile devices.
Improved FPS and CPU utilization for the virtual background feature
- By improving the Frame Per Second (FPS) processing when the virtual background or blur background feature is enabled, we now yield better FPS on low-end devices.
- We have also moved YUV-1420 from the CPU to GPU and performed a few other conversions, leading to less CPU utilization.

Resolved issues

The following table lists the issues we have resolved in VidyoClient for API Binary Library version 22.3.0:

VidyoClient for API Binary Library Version 22.3.0 - Resolved Issue
Key	Summary
VIDVCB-36	A bug in the JSON parser that occurred while parsing ext_data_type has been fixed; therefore, the ext_data_type parsing error no longer occurs.
VIDVCB-30	An issue was fixed where iPad OS devices with a sampling rate of 44.1KHz produced echo starting with iPad OS 15.3.1. This release changed the sampling rate for audio capturing to 48KHz for the entire iOS platform, thereby preventing the echo.
VIDVCB-4	An issue was fixed where the VidyoReplay recording would display a "No camera" icon even when there were still video-enabled participants in the call. This occurred when a client resolution that had an odd width or height was received. Vidyo supports three spatial layers when a remote participant is on a limited bandwidth network. When the system has a resolution such as 960x540p, the third spatial layer is 240x135p which is a resolution with an odd number of lines. For VP8 and VP9 codecs, VidyoClient normalizes this resolution from an odd number of lines to an even number since YUV supports only even resolutions.

Known issues

There are no new known issues in this release.

VidyoClient API Binary Library: About Version 22.1.0

What's new in this release

VidyoClient 22.1 ships royalty-free
- This release supports VP8/VP9 only and is royalty-free.
- This royalty-free version does not require an install license from the VidyoPortal. Since VP9 uses a client library, which doesn't consume a license, you no longer need go to the Admin Portal Advanced Options to configure your system to stop consuming a license.
- Requires VidyoPortal 22.1.x or later only. It does not support versions of the VidyoPortal and VidyoRouter earlier than 22.1.x.
- VP9 gets automatically set up when you upgrade to this version.
H264 codec no longer supported
- We now exclusively use VP9/VP8 codec for video and content sharing—VidyoClient SDK will only encode/decode video on tenants that support VP8/VP9.
- Starting with this release, if a client that supports H264 codec joins a call with a client that supports VP8/VP9 codec only, there will be no video. It will be an audio-only call.
- If a VP8/VP9 client joins a tenant that does not support VP8/VP9, the call will be an audio-only for the client. Other clients in the conference that support H264 will be able to see video and share content.
Enhanced video frame capturing logic for content sharing on Windows and Mac
- Users of the VidyoClient on Windows and Mac can now experience better quality video conferences as we have greatly enhanced the frame capturing logic for content sharing in these environments.
Support for Mac move to ARM processors
- We have updated Vidyo SDK to support macOS on Apple Silicon. We now have a separate package for all the VidyoClient libraries for MAC ARM architecture, VidyoClient-macOSSDK-arm64-TRINITY-22_1_0_xxxx.zip.
- We also updated the 3rd party libraries commonly used in Vidyo SDK plugins (OpenSSL 1.1.1l , Libsrtp 2.4.0, Opus 1.3.1, Libvpx 1.9.0).
End-to-end content sharing enhancements
- Multiple enhancements have been added to end-to-end content sharing to provide a better user experience.
Performance improvements
- In this release, we’ve updated internal processes for enhanced functionality and performance.

JavaScript Library

VidyoClient for WebRTC JavaScript Library: About General Availability (GA) Version 22.3.0

What's new in this release

Support for DTMF tones
- This release adds the ability to send Dual Tone Multi-Frequency (DTMF) tones on the audio channel. You can use this in combination with the InviteToConference API to invite a SIP endpoint and enter IVR selection.
  - For more information about sending DTMF over WebRTC, refer to the browser capability described in the Using DTMF with WebRTC article.
  - For more information about the Vidyo Web User Services API InviteToConference Request, refer to the Web Services API User Guide.
Improved network conditions adaptation
- The code has been optimized to adapt the outgoing video resolution more rapidly to changing network conditions. This means that the sent camera resolution now adapts more quickly to meet the available bandwidth.
Enhanced receiver algorithm
- We have improved the algorithm at the receiver side to take better advantage of the device type (desktop, Android phone or tablet, or iOS phone or tablet) and the receive bandwidth.
- With this enhancement, you will be able to receive clearer audio without interruption as well as view better quality video tiles. In addition, this feature enables video tiles to be restored when network conditions improve.
Support for multiple tiles on tablets
- You can now see more call participants when you join a video call with your Android or iOS tablet. Both types of tablets now support up to three video tiles.
VP9 SVC support for Safari
- VP9 SVC (Scalable Video Coding) is now supported on macOS Safari. When compared with VP8, this improves video quality while using significantly less bandwidth.

Resolved issues

The following table lists the issues we have resolved in VidyoClient for WebRTC JavaScript Library version 22.3.0:

VidyoClient for WebRTC JavaScript Library Version 22.3.0 - Resolved Issues
Key	Summary
IOWEBRTC-2964	An issue was fixed where the Native WebRTC client was not receiving remote microphone mute/unmute events from VidyoConnect Binary clients.
IOWEBRTC-2923	When the vidyoConnector.ShowViewLabel(...) method is called with the showViewLabel parameter set to false to hide the label, visible artifacts no longer appear.
IOWEBRTC-2773	We've improved compliance with the Content-Security-Policy (CSP): "unsafe-eval" is no longer needed to use the Native WebRTC JavaScript library.
IOWEBRTC-2009	The enhanced receiver algorithm feature introduced in 22.3.0 fixed some issues, such as the number of participant video tiles sometimes dropping to one even under good network conditions.

Known issues

The following table lists the issues that still remain, but you can be sure our teams are working hard to fix them.

VidyoClient for WebRTC JavaScript Library Version 22.2.0 - Known Issues
Key	Summary
IOWEBRTC-2978	On macOS, video from remote participants may freeze after disconnecting a Bluetooth headset while in a call.
IOWEBRTC-2876	On macOS and occasionally on iOS, audio stops sending when a call participant switches to another microphone or plugs in an additional microphone.
IOWEBRTC-2650	There is an issue with unprocessed audio occurring when a stethoscope is connected and selected as a microphone, causing the remote user not to be heard. This issue was investigated and determined to be an issue with Safari. When Safari is acquiring audio stream from one microphone, it breaks all previous streams from other microphones. For more information, refer to https://bugs.webkit.org/show_bug.cgi?id=235713.
IOWEBRTC-2619	Some Samsung devices on Android 11 may not be able to join a call or send/receive media. This was investigated and was determined to be an issue with Samsung.
IOWEBRTC-2423	If a user mutes their microphone during a call, the browser still reports that the microphone is in use. This is not a bug. This behavior occurs because VidyoClient still has access to the muted microphone resource to ensure that unmuting the microphone works properly.
IOWEBRTC-2222	When a mobile device is in portrait mode, the browser rotates the applied video constraints and switches to landscape mode. This has been investigated and determined to be the behavior for the current Safari and Chrome browsers.
IOWEBRTC-2218	When using VP9 codec in desktop or mobile Chrome browsers, the application reacts too quickly to bandwidth fluctuations, which can sometimes lead to reduced outgoing video resolution.
IOWEBRTC-1942	On iOS, when a user starts sharing their camera (selects the camera as a source for content sharing), the video stream stops and remote participants see a black video tile. This is due to an iOS bug: https://bugs.webkit.org/show_bug.cgi?id=179363
IOWEBRTC-1823	VP8/VP9 users with limits for receive/send bandwidth may experience fluctuations in frames per second (FPS) and resolution during video calls.
IOWEBRTC-1784	Audio lip-sync is delayed on iOS Safari after flipping the camera during a call. This is a known issue with Safari that cannot be fixed by Enghouse Vidyo at this time.
IOWEBRTC-1719	On iOS 14+, video continues to transmit during an incoming voice call.
IOWEBRTC-1705	Chrome browser sometimes encodes only 720p/10-15 fps, even when the network has enough bandwidth to support a higher frame rate.
IOWEBRTC-1673	On Chrome in macOS with dual-core CPUs, the resolution drops when the CPU idle is at 30-50%.

VidyoClient for WebRTC JavaScript Library: About General Availability (GA) Version 22.2.0

What's new in this release

Support for DTX mode
- DTX (discontinuous transmission) mode is now enabled for the OPUS codec. This mode reduces the bandwidth used for audio when the participant is silent. It also reduces CPU load on the receiver side since there are fewer audio frames to decode.
- This feature works across all supported browsers for both desktop and mobile.

VidyoClient API Binary Library: About Version 21.5.0

What's new in this release

Support for a virtual audio source

VidyoClient now supports a virtual audio source. Using this feature, an application can inject audio frames into a conference using VidyoConnector APIs.

Support for content sharing with audio

VidyoClient can now capture audio coming from the system default output device and send it to all the participants in the conference. Therefore, when users share applications that play audio, such as YouTube or the Windows Media Player, the other conference participants will be able to both see video and hear audio from that shared application.
- This feature is supported only on high-end Windows systems. Support for macOS will be added in a future release.

Dynamic linking of SDK for image segmentation

The image segmentation functionality (for example, background blur and virtual background) is an optional feature. That being so, this enhancement allows the application to exclude the segmentation SDK when running with VidyoClient if the image segmentation functionality is not used in the application.

Resolved issues

The following table lists the resolved issues in VidyoClient API version 21.5.0:

VidyoClient API Version 21.5.0 - Resolved Issues
Key	Summary
IO-3678	An issue that prevented some users from joining calls with a specific version of the router has been resolved.
IO-3674	A crash when using VidyoClient 21.4 or 21.3 with experimental options no longer occurs.
IO-3570	An issue was resolved that caused some VidyoConnect call participants’ tiles to appear black until audio was received from those participants.
IO-3288	An issue was resolved where, when network performance degraded, the audio quality became poor although the video and content sharing quality remained the same.

Known issues

Key	Summary
IO-3500 and IO-3466	When the content sharing with audio feature is used during a conference, VidyoClient will share the audio being played to the speaker selected as the default speaker in the operating system. Therefore, you must ensure that no other application other than the application you are sharing is playing audio to the speaker.
IO-3456	Audio is shared only from the operating system's default output device. Therefore, if you want to share audio in your conference, you must select the default device as your audio playback device on the application from which you want to share audio. If a device other than the OS default device is selected, audio won't be shared.

VidyoClient API Binary Library: About Version 21.4.0

What's new in this release

Redundancy support for Opus

This release adds RED support for the Opus codec. RED, which stands for REDundant coding, is an RTP payload format defined in RFC 2198 for encoding redundant audio or video data.
- Sending redundant data enables the recovery of packets lost under lossy network conditions. If a packet is lost, the missing information may be reconstructed at the receiver from the redundant data that arrives in the following packet(s).

iOS device selection and audio routing enhancements

If you're an iOS user, you'll find that this release enables you to more easily and successfully select and switch between your microphone and speaker devices.

VidyoClient for WebRTC JavaScript Library Version 21.6.1 LA - Known Issues
Key	Summary
IOWEBRTC-2441	On iOS 15 Safari, participants experience low sound output in calls. This is due to a known Apple bug in Safari/IOS15: https://bugs.webkit.org/show_bug.cgi?id=230902 Workaround: Connecting and disconnecting a headset can sometimes fix the issue.
IOWEBRTC-2423	A muted microphone may appear to be in use, causing users to think that the microphone is in use when it is not.
IOWEBRTC-2402	On iOS 15 Safari, if a user switches to another incoming call during a video meeting, the remote video is not restored after that user returns to the meeting. This is due to a known bug in iOS 15: https://bugs.webkit.org/show_bug.cgi?id=230537
IOWEBRTC-2339	On iOS Safari 15, if the mobile user puts the video meeting in the background or switches to another browser tab, sometimes the video does not resume after the app is brought to the foreground. This is due to an iOS bug, which is fixed in the iOS 15.2 release: https://bugs.webkit.org/show_bug.cgi?id=230538 Workaround: Mute and unmute the camera.
IOWEBRTC-2274	In some cameras with zoom, the zoom function does not work. This issue occurs in VidyoClient binary 21.6.0.4 and earlier.
IOWEBRTC-2222	When a mobile device is in Portrait mode, the browser rotates the applied video constraints and switches to Landscape mode. This has been investigated and determined to be the behavior for the current Safari and Chrome browsers.
IOWEBRTC-2218	When using VP9 codec in desktop or mobile Chrome browsers, the application reacts too quickly to bandwidth fluctuations, which can sometimes lead to reduced outgoing video resolution.
IOWEBRTC-1942	On iOS, when a user starts sharing their camera (selects the camera as a source for content sharing), the video stream stops and remote participants see a black video tile. This is due to an iOS bug: https://bugs.webkit.org/show_bug.cgi?id=179363
IOWEBRTC-1921	On iOS Safari, video tiles that drop due to network conditions sometimes do not restore when network conditions improve. Workaround: Drop off the call and then rejoin.
IOWEBRTC-1863	On iOS Safari, low video resolution can occur if a user puts the mobile app in the background during a call, and then brings it back to the foreground.
IOWEBRTC-1861	On iOS 14.4-14.7.1, crackling audio noise can be heard during the first two seconds of the remote user audio stream. This is due to an iOS issue: https://bugs.webkit.org/show_bug.cgi?id=219161
IOWEBRTC-1823	VP8/VP9 users with limits for receive/send bandwidth may experience fluctuations in frames per second (FPS) and resolution during video calls.
IOWEBRTC-1784	Audio lip-sync is delayed on iOS Safari after flipping the camera during a call. This is a known issue with Safari that cannot be fixed by Enghouse Vidyo at this time.
IOWEBRTC-1719	On iOS 14+, video continues to transmit during an incoming voice call.
IOWEBRTC-1705	Chrome browser sometimes encodes only 720p/10-15 fps, even when the network has enough bandwidth to support a higher frame rate.
IOWEBRTC-1673	On Chrome in macOS with dual-core CPUs, the resolution drops when the CPU idle is at 30-50%.
IOWEBRTC-1637	Occasionally, after one hour in a call, the voices of meeting participants begin to sound distorted. Some users have described this distortion as "robotic voice". This issue has been investigated and determined to be a browser bug.

Binary Library

VidyoClient API Binary Library: About Version 20.3.0

What's new in this release

High frame rate content share

If you've ever wanted to share a streaming video or other high frame rate content during a video call, now you can! With version 20.3.0, you can share content up to 30 FPS.
High frame rate content share is supported for Windows®, macOS®, Android™, and iOS.

Waiting room

The Waiting Room feature prevents meeting participants from seeing or hearing each other until the room owner joins the meeting or the moderator selects a presenter.
As soon as the room owner joins or the presenter is selected, the meeting begins and all the participants can see each other. In addition:
- If Group mode is enabled, all the participants’ microphones will be unmuted.
- If Presenter mode is enabled, all the participants’ microphones will remain muted.

Presenter node

When Presenter mode is enabled:
- All the participants remain in Waiting Room mode until the moderator selects the presenter.
- The microphones of all the participants are muted, and they must use the Raise Hand button to request to be unmuted.
- The conference moderator sees the Raise Hand requests and can select who to unmute.

Call moderation

The moderator can control many aspects of the video meeting, such as:
- Invite new participants.
- Mute and unmute individual or all participants' microphones and cameras.
- Lock and unlock the room.
- Switch to Presenter mode.
- Start, stop, pause, and resume recording.
- Disconnect participants and end the call.
If you are not the room owner, you must enter the moderator PIN to become the moderator.

Webcast indication API

A new API provides you with the ability to show a webcast indication when there is an ongoing webcast during a video call.

Resolved issues

VidyoClient API Binary Library: About Version 20.2.0

What's new in this release

Multiple enhancements for Custom Layout

Multiple enhancements have been added to the Custom Layout in order to provide a better user experience. These enhancements include APIs that the application can use to reduce the chance of getting black video tiles as well as to reduce the receive bandwidth usage.
The VidyoConnector Sample has also been updated to include a new layout where all the tiles are equal-sized.

Disabling video under prolonged low bandwidth conditions

If an individual user in a call experiences prolonged low network bandwidth, their video feed will automatically shut off. By doing so, their limited bandwidth can be used to transmit their audio.
Whenever the VidyoClient API shuts off a video stream due to prolonged low bandwidth, it will notify the application.
This feature is disabled by default. For information about how to enable it, contact Enghouse Vidyo as listed in the Contact Us article.

Automatically reconnecting to conferences

Calls will now automatically attempt to reconnect if they were disconnected under conditions where Enghouse Vidyo determines a reconnection attempt may be successful.
If this occurs, the affected users will be notified of the following:
- When a reconnection is being attempted.
- The number of attempts at reconnection.
- Whether the reconnection is successful or not.
This feature is disabled by default. For information about how to enable it, contact Enghouse Vidyo as listed in the Contact Us article.

Support for additional processors

We can now detect newer processors including the Intel Cannon Lake, Intel Ice Lake, and Apple A13, thereby enabling our customers to achieve top-level performance.

Disabling the default install license behavior

By default, an install license is consumed whenever a VidyoClient-based app is installed on a new machine. However, an Advanced option is now available that enables you to disable the default install license behavior.
This feature is disabled by default. For information about how to enable it, contact Enghouse Vidyo as listed in the Contact Us article or by reaching out to your authorized Vidyo Reseller.

Pinning and unpinning one video tile at a time

The ability to pin and unpin one video tile at a time on a composite layout has been added.
Support for pinning multiple participant tiles is not yet available.

Number of encoded spatial layers added to statistics

For easier debugging, the statistics now identify the number of spatial layers received, decoded, or rendered by the receiving client.

New and updated APIs

VidyoConnectorSetPool API for guests
- The VidyoConnectorSetPool API can now be used for guest users. This API enables the application to determine which VidyoRouter in the network will be used for the call by the client.
New API to lock orientation of mobile devices
- The new VidyoLocalCameraSetOrientation API enables the application to lock the orientation of the video rendering window.
