[FFmpeg-devel] [PATCH 2/2] avformat/flvenc: add extract_extradata bsf for new video codecs

[Zhao Zhili]

From: Zhao Zhili <zhilizhao at 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.
