libopenshot/src
History
Jonathan Thomas 1ad401c66d - Added a new common mask_reader feature at EffectBase, so all video effects can be mask-limited automatically (audio effects ignore it). 
- Added optional Mask Mode overrides for Blur, Saturation, Brightness, Hue, Pixelate, and Sharpen (Limit to Mask, Vary Strength).
- Kept unified mask property naming (mask_reader) with legacy JSON compatibility where needed.
- Added/updated unit tests for base mask behavior, per-effect mode behavior, and JSON round-trips.
- Fixed profile tests to write generated files into the build/test directory instead of the source examples/ folder.

2026-02-13 12:13:44 -06:00

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.

Also adding a new SetDirectionHint function to FrameMapper class - so our Clip class can inform the FrameMapper of its direction at any given moment.

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.
2025-12-08 17:07:21 -06:00
