Fix video and audio streaming

[pravusjif]

Even after all the fixes already in place in our video player library, It has been reported in several issues that video and audio streaming has problems in the desktop client.

Audio Streaming

Apparently the video streaming audio only works for a couple of seconds and then it stops, this was reported by several users at Discord.

Video Streaming

Issue with the most information on the problem:

• Video delivery not happening in the Desktop Beta #208

Other issues reporting the same problem:

• Video Stream just displaying as a white box #360
• Streaming not working at -118,120 #279
• Music and Video not working issues#494

Some coordinates in which the problem has been reported:

• 2, 55
• 110, -23
• -17, -122
• -22, 37
• -94,103
• -118,120

Approach

We'll try to solve the issue by integrating a unity plugin that apparently works with more formats than we can currently support on our own video player library. That task is tracked at

• Integrate unity plugin AVPro Video free version to define if we can use it #325

Acceptance Criteria

• Finish integrating video player library solution in unity (and adding it to the building pipeline in a way that doesn't expose it as open-source since the plugin isn't open source)
• Have video and audio streaming working correctly in the reported scenes

Are there any updates on this, and how can we help?

@popuz this bug has been open for months. With the recent improvements to streaming, is it still relevant? If not, it would be great to verify and close this card.

hi @xavi-dcl . I was dealing with streaming in the browser which is a bit different. Desktop with AVPro was on the @dalkia hands. However, we will probably need to discuss it together to sync video codecs and formats which we use (when uploading is fully on our side)

[dalkia]

Hi @xavi-dcl. We have implemented AVPro plugin in Desktop, and we didn't have a new report of videos not working there. This issue is safe to close.
Agreed with @popuz, we should set up that discussion.

Closing this issue, as the scope of the task has been completed.

@aixaCode @pravusjif I've tested this and the streaming still does not work on desktop client.
Please test with this: https://livepeercdn.com/recordings/b77ff043-132c-4804-81b2-3cf7dafe5767/index.m3u8

Also, I'm using the latest desktop client.
