[FFmpeg-devel] [PATCH] avformat/flvdec: RtmpSampleAccess no longer breaks stream detection

[Peter van der Spek]

Since release 4.2, FFmpeg fails to detect the correct streams in an RTMP
stream that contains a |RtmpSampleAccess AMF object prior to the
onMetaData AMF object. In the debug log it would show "[flv] Unknown
type |RtmpSampleAccess".

With this change the RTMP streams are correctly detected when there
is a |RtmpSampleAccess object prior to the onMetaData object.
