Subject: [FFmpeg-devel] [PATCH] avcodec/decode: Fix avcodec parameters when bsfs are enable by decoder
Date: Thu, 6 Mar 2025 15:56:27 +0800
Message-ID: <tencent_7267E92A905315DC694B81E629108EA6C006@qq.com> (raw)
From: Zhao Zhili <zhilizhao@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.
