8c7b463e38 Improvements to the ClearAllCache() function, allowing both shallow and deep clearing. Lots of bug fixes in VideoCacheThread, to correctly pre-roll and cache the correct frames, and a new method of disabling/enabling the cache thread. 2022-09-15 18:33:06 -05:00

35d4629df6 Large refactor to caching and playback timing:
- Support different speeds (-1X, 2X, 4X, etc...)
 - Clamp getFrame between 1 and timeline length
 - Support rewind using new timing code
 - Caching in both directions (based on previous speed)
 - Removing mutex from Timeline::GetFrame (cached path)
 - Caching supports actual speed now
 - Bust cache and trigger pre-roll if we encounter too many uncached frames. This will re-sync the video + audio threads.
 - Sleep less in cache loop / Adjusting min frames to 24 (trial and error). Too few and backwards playback suffers. Too many and all playback waits.

133bae40c3 Adding pre-roll to VideoCacheThread, and making video & audio threads wait for the isReady() method before playing. Also fixed an audio bug where our internal buffer was not being cleared on seek. Removed some unused caching from Clip, and did some minor refactor on FrameMapper/Clip cache clearing. 2022-01-26 17:56:33 -06:00

a5f35fb42a Refactoring the VideoCacheThread to check every frame before requesting it. Adding a new method: Contains() to our cache objects, to facilitate this. Removing cache clearning experimental code from Timeline (causing playback issues). Refactoring PrivatePlayer playback timing code, to calculate an average # of frame difference between audio and video threads, and slowly adjust back towards zero when needed. 2022-01-14 15:16:04 -06:00

0c4e1bcce4 Improving performance after working with google-prof, to profile CPU. Calling OMP_MP_NUM_PROCESSORS less often, since it's quite expensive according to profiling. Adjusting Timeline final_cache to match the video caching thread max_frames, so one doesn't clobber the other. Also, fixing an issue with openshot-player, where a video file with no audio skips horribly. 2021-02-04 17:28:07 -06:00

172348417c Improvement to video caching thread, to recover from the separation of cache vs display frame #. Also found a mutex that was needed, to prevent crashing when the video thread calls timeline::GetFrame at certain times... colliding with another thread (and independent of OpenMP). 2020-10-23 17:52:20 -05:00
