MP4 Videos Play Back Stuttering/Freezing. #655

Open duy64 opened 3 years ago

duy64 commented 3 years ago

I have checked the forum for an answer, but found nothing so I reported here. Video Snaps playing with skipping frames or sometimes freezes, while the audio still playing. Attract Mode 2.6.1 and the nightly builds on windows 10. This is just an example of the many videos I got from the Arcade Database website. Videos can be found here videos The SD videos play fine, it's just the HD videos are not playing properly in Attract Mode. I have tested the videos outside of Attract Mode and they seem to play fine. I have pasted the video info below.

I have run into the same issue. Emulation Station seems to run the .mp4 snaps just fine, but attract mode will lag or freeze. This occurs with all video clips. The audio does run fine however.

I'm running a pi 4, 4gb with 200gb SanDisk Ultra card.

Emulation Station is using an omxplayer to play videos which is using a hardware overlay on top of the ES. This is fast enough to handle 1080p videos, but has some limitations. You can only display the video in a rectangle ( no perspective transforms allowed ) It's always on top, so you cannot draw any overlay, text or icon on top. AM uses MMAL which does not do zero copy video decoding. Even RPI4 is just too slow to do 1080p smoothly rendered on a texture.

I'm gonna try another approach soon and see if it helps with the performance.

I hope you can fix for windows port too, or atleast give us the option to choose the default media player or decoder for video playback. I know there is an option to choose the decoder but it is limited to just hardware dxva2 and software but it doesn't specifies which one.
