Hi,
Trying to mux prores into flv triggers an av_assert2, because the prores codec
tag doesn't fit in one byte.
Attached is a patch fixing this.
Best regards,
Andreas

Subject: [PATCH] avformat/flvenc: check that the codec_tag fits in one byte
flags is later written with avio_w8 and if it doesn't fit in one byte it
triggers an av_assert2.
