Revision c09de25 by Richard Antalik (temp-vse-fast-scrubbing2) February 24, 2021, 23:58 (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. Differential Revision: https://developer.blender.org/D10529 |
