Revision 88604b7 by Richard Antalik (master) March 2, 2021, 11:23 (GMT) |
FFmpeg: Improve scrubbing performance Applying negative offset to seek position before scanning doesnn't have any effect. This change results in 1.5x faster seeking (random frame, average value) in sample file with 30 frame GOP length. If I am not mistaken, B frames can have pts that can be less than pts of I frame that must be decoded. Even in this case though, B frame packet will be stored after that I frame. In addition, preseek value is de facto hardcoded so seeking would fail if it could. This can be hard to spot though. Reviewed By: sergey Differential Revision: https://developer.blender.org/D10529 |
