Bug: VP9 compressed WEBM files are broken

Open IdontKnowNothin opened this issue 9 months ago • 1 comments

Describe the bug

A WEBM video file that has been compressed with VP9 is broken in-game. Seen issues mostly consist of the video file having incorrect timings or possibly jumping randomly along the video.

Note: only tested with vgui_movie_display.

To Reproduce

  1. Create WEBM file compressed with VP9.
  2. Apply the WEBM file to a vgui_movie_display.
  3. Compile and open the map in-game.
  4. View video.

Issue Map

No specific map.

Expected Behavior

The video should play normally and not broken, just like compressing with VP8 would.

Operating System

No response

Noting additional regressions with playback when restarting a map while a video is still playing, probably tied to #971 and #583?
