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. 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.

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