[FFmpeg-devel] [PATCH] avcodec/decode: Fix avcodec parameters when bsfs are enable by decoder

[Zhao Zhili]

From: Zhao Zhili <zhilizhao at tencent.com>

BSF can update extradata, e.g., vvc_mp4toannexb. If we don't copy
bsf->par_out back to avcodec context, decoder can get extradata in
mp4 format, while packets are in annexb format.
