History
Jonathan Thomas 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.

AudioLocation.h
Large refactor of Clip::GetFrame and time-remapping of audio samples.
2023-02-27 22:11:13 -06:00
AudioReaderSource.cpp
Adding default audio buffer size to libopenshot settings, and setting default to 512. Also, adding some debugging output. This will allow users to override the default audio buffer size, to better customize for their system.
2024-12-09 15:15:12 -06:00
AudioReaderSource.h
Big refactor of AudioReaderSource, to be simpler, and only fill the audio samples requested (removed double/internal buffer complexity). Also, we now initialize the audio device manager at a specific sampleRate and # of channels correctly. Removed 'latency' adjustment in PrivatePlayer (no longer needed with no read-ahead buffer). Increased the min_frames_required on the video cache to 24.
2022-01-31 15:18:07 -06:00

Also adding a new SetDirectionHint function to FrameMapper class - so our Clip class can inform the FrameMapper of its direction at any given moment. Also, clear resampler when changing directions inside a Time curve (since the audio buffer will be flipped - the resampler internal cache must be cleared).

2025-06-15 16:01:17 -05:00
DummyReader.cpp
Silence openshot::Frame audio when requesting a Clip::GetFrame() past the end of the Clip's Reader. For example, if a Clip has 1000 frames, and the user requests frame 1001, we will return the last cached openshot::Frame object, but we don't want to repeat the audio samples (causing a stutter). Any frame past the end of the reader, should always silence the audio samples. Also, fixed a few invalid comments, and added a Unit test.

Enums.h
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.
