|
|
Verify sync: mpv video player + dual waveform display.
|
|
|
|
Modes:
|
|
--mode short : extracted 30s parts (video_a + wav_a + wav_b)
|
|
--mode full : synced output MKV (extracts audio streams from it)
|
|
|
|
Features:
|
|
- Smooth video playback via mpv (handles all codecs natively)
|
|
- Audio playback: A only, B only, or A+B mix via sounddevice
|
|
- Combined waveform overlay (A and B in different colors)
|
|
- Two separate waveform graphs with playhead
|
|
- Zoomable waveforms (scroll) with linked x-axes
|
|
- Timeline seek bar synced to video position
|
|
- Toggle A/B on/off, volume
|
|
|
|
Usage:
|
|
make verify LAG=0.042
|
|
python verify_sync.py --config config.toml --lag 0.042 --mode short
|
|
python verify_sync.py --synced output/movie_synced.mkv --lag 0.042 --mode full
