[FFmpeg-devel] [PATCH] avcodec/decode: Do not output subtitle frames if the packet is marked with `AV_PKT_FLAG_DISCARD`.

[Darren Mo]

To clarify, do you mean we should merge this now or wait for the second patch, which fixes the root cause?

A potential fix for the root cause would be to handle boundary packets by changing their timestamps to fit the edit boundary. (That would be a separate patch though.)
