d70e80eac4 Harden playback/cache path for malformed media and concurrent timeline updates 
- Invalidate timeline cache on ApplyJsonDiff() clip insert (remove affected frame range).
  - Add lock in Timeline::ClearAllCache() for safe concurrent access.
  - Make VideoCacheThread cross-thread state safe (atomics + seek-state mutex).
  - Lock CacheMemory::Contains() to avoid races.
  - Handle malformed audio streams in FFmpegReader by disabling invalid audio and continuing video-only.
  - Add FPS/timebase safety fallbacks in FFmpeg frame/PTS math.
  - Guard Frame::GetSamplesPerFrame() against invalid inputs.
  - Add/adjust regression tests for cache invalidation and invalid rate handling.

2e4e12d2c7 Setting a minimum # of frames (floor) in Timeline, FFmpegReader, and FrameMapper - so low cpu/thread systems don't end up with a tiny # that makes passing our unit tests difficult. 2026-02-09 22:10:32 -06:00

d6b54091d7 Adding minimum cache size floor, for systems with very few cores. This is required to fix a failure running unit tests on our GitLab runners. 2026-02-09 21:14:45 -06:00

01e60463db FFmpegReader: fix sparse-VFR stall and stabilize missing-frame image fallback 
- prevent ReadStream() infinite loop when packet counters stall at EOF with no packet/hold state by detecting no-progress and forcing EOF completion
  - improve missing-frame handling on sparse timelines by preferring chronological image sources:
      - previous finalized frame (f->number - 1)
      - last finalized video frame (last_final_video_frame)
      - last decoded video frame only if not from the future
      - black frame only as last resort
  - use the same finalized/decoded fallback when largest_frame_processed is no longer cached
  - track/reset last_final_video_frame across finalize/seek/close lifecycle

  Fixes:

  - hard stall around gap frames
  - black flashing from cache churn on sparse streams
  - out-of-order jitter caused by reusing future-decoded frames

f3c4504662 Improve benchmark regression caused by aggressive memory trimming, and caches that were too small. A new debounce strategy for memory trimming (1 time max per 30 seconds). 2026-02-06 23:11:00 -06:00

de012ac6c8 Improve seek retry fallback and clean up hw decode logging 
- add adaptive seek fallback and switch fprintf to ZmqLogger
- improves seeking on certain files by up to 30% (faster)
- avoids situations where seeking too far would sometimes freeze on certain videos

353e6ae4f1 Changing python install detected folder, to be relative folder. This is breaking on some build servers, due to returning an absolute path that is installed outside of the install prefix. 2025-12-16 21:05:23 -06:00

7fdd145dc2 Adding new memory trimming to more forcefully return memory to the OS after major memory clearing events (i.e. clearing all cache, closing readers, or large amounts of cache cleared). Also, refactoring default cache sizes in Timeline, FrameMapper, and FFmpegReader to better support high frame rate and high resolution videos (i.e. 4k 60 fps) so we don't immediately run out of memory. 2025-12-14 23:53:36 -06:00

eea55982fd FFmpegReader: add duration strategy modes and unify duration/frame calculations. This is a potentially breaking change, where we ensure all durations and video_length calculations coming from FFmpegReader are now fully consistent - even if we must slightly adjust a duration from the video or audio stream. This keeps the 2 attributes identical in meaning (video_length X FPS == duration, no exceptions). Unknown durations are no longer -1 video_length but 0, and 0 duration. 2025-12-08 17:07:21 -06:00
