[FFmpeg-devel] [PATCH v2] avformat/wavenc: skip writing incorrect peak-of-peaks position value
According to EBU tech 3285 supplement 3 the dwPosPeakOfPeaks field should contain the absolute position to the maximum audio sample value, but the current implementation writes the relative peak frame index instead. Fix the issue by writing the "unknown" value (-1) for now until the feature is implemented correctly.
