ffplay is too slow to play HEVC 4K / 60FPS video files #273

Closed qrp73 closed 3 months ago

qrp73 commented 3 months ago

Steps to reproduce: 1) Open virtual virtual terminal: Alt+Ctrl+F1 2) wget https://img.photographyblog.com/reviews/apple_iphone_13_pro/sample_images/4K60p.mov 3) ffplay 4K60p.mov

Expected result: playback is no worse than with VLC player

Actual result: playback is very laggy and almost not watchable while the same file can be played with VLC player with watchable speed.

The same issue happens when running ffplay 4K60p.mov from Wayfire terminal window

Tested on RPI 4 rev 1.5

ffplay is effectively only a demo program and doesn't have any display stages that can efficiently deal with hardware buffers. VLC does. So, sorry, this is never going to work.

Thanks for the info John!
