Subject: [FFmpeg-devel] [PATCH 2/2] avformat/flvenc: add extract_extradata bsf for new video codecs
Date: Sat, 18 Nov 2023 16:03:12 +0800
Message-ID: <tencent_B4ADD238C5C015B63C686E00816B867F1A0A@qq.com> (raw)
In-Reply-To: <20231118080312.657877-1-quinkblack@foxmail.com>
From: Zhao Zhili <zhilizhao@tencent.com>
When encoders don't support global header like MediaCodec, FLV
muxer needs to add extract_extradata bsf automatically. The codec
list doesn't include VP9 since it's not supported by
extract_extradata.
