Two separate bugs in AudioSaveHelper.save_audio caused libmp3lame's avcodec_open2 to fail with EINVAL ([Errno 22] Invalid argument): 1. codec_context.qscale is exposed by PyAV as a bool flag rather than the int quality scale libmp3lame expects, so assigning a level (1) to it for "V0" quality made avcodec_open2 reject the codec context. libmp3lame's default VBR mode is roughly equivalent to V0 quality, so the assignment is simply removed. 2. libmp3lame only accepts a fixed set of sample rates (8000, 11025, 12000, 16000, 22050, 24000, 32000, 44100, 48000 Hz). Audio sources that output other rates (e.g. 40000 Hz from some RVC models) were passed through unchanged, causing avcodec_open2 to fail. MP3 output now remaps to the closest supported rate and resamples, mirroring the existing Opus rate-handling logic. Verified by reproducing both failures directly against PyAV with the unpatched code and confirming the patched AudioSaveHelper.save_audio encodes successfully for both the "V0" quality and 40 kHz cases. Fixes #13937 |
