>Is it not possible to extract all of them simultaneously? Each of the extractable CC bitstreams would need to be exposed as an independent eia608 AVStream, because each represents a distinct stream. They can’t be commingled (which is what this patch addressed). I’m not sure of a way to sanely

[FFmpeg-devel] [PATCH v3 1/6] avcodec/mpeg12dec: extract only one type of CC substream

2024-03-12 Thread Marth64
In MPEG-2 user data, there can be different types of Closed Captions formats embedded (A53, SCTE-20, or DVD). The current behavior of the CC extraction code in the MPEG-2 decoder is to not be aware of multiple formats if multiple exist, therefore allowing one format to overwrite the other during
