94fab00048 Updating video_length and duration calculations to be consistent on image readers also (QtImageReader, ImageReader) 2025-12-08 18:33:23 -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

af9a4893ed Fixing regression inside AudioWaveformer so it uses a proper detached reader, and no longer mutates the Clip's reader (preventing a bug which caused our video to disappear when waveforms were used on the clip) 2025-11-24 18:33:25 -06:00

d4647b5525 Refactoring the AudioWaveformer again, this time to de-couple it from the actual clip object passed to it, and to no longer iterate over the potential longer time keyframes using GetFrame alone. Now, we only decode audio-streams, and only get the original samples (reduced sample rate drastically), and finally we apply keyframes (volume and time) to modify our original samples. This is a HUGE speed-up boost for waveform generation. 2025-11-23 14:11:53 -06:00

0dfc8a8a37 Updating 1D and 3D unit tests for Color Map to use a more obvious cube color map, with 1D = green and blue, and 3D = red and blue. 2025-11-18 18:11:37 -06:00

2f82e7d27b Adding support for 1D and 3D LUT Color Map files. Also added new unit tests to verify 1D and 3D LUT files. 2025-11-18 14:26:59 -06:00

a7dfc596ca Fixing regression in Clip::init_reader_rotation() function, which could sometimes override scale_x and scale_y, when a rotation keyframe contained more than 1 point. 2025-11-13 16:18:18 -06:00

5596344575 Fixing AudioWaveformer::ExtractSamples to pause temporarily when a clip's reader is closed, and resume extracting when it's open again. This prevents a very common crash / bug when generating waveforms for longer audio clips and continuing to make chagnes on the timeline (which closes all clips temporarily - interrupting the waveform extracting). 2025-11-06 14:51:57 -06:00

7e29fc0935 Improving audio directionality, with new function: SetAudioDirection(), so we can safely flip audio buffer direction when needed (i.e. time curves, reversed time). 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). 2025-10-11 16:29:11 -05:00

0c15c1692e Adding new reversed time curve unit test, to verify 230,000 samples are actually reversed over the length of the clip without skipping or missing a single one. 2025-09-26 18:34:33 -05:00

c165eca5d8 Improving AudioWaveformer to be able to correctly generate waveforms for time-curved clips that have a modified duration/video_length (i.e. repeated clips, slowled down clips, etc...). Adding a new ReaderBase.h VideoLength() that can be overridden in Clip.cpp when time curves are involved. 2025-09-22 12:28:12 -05:00
