in commit d7638d8dfc3c4ffd0dc18a64937a5a07ed67b354
as unknown metadata packets now result in an opaque data stream, and the
|RtmpSampleAccess packet was an "unknown" metadata packet type.
With this change the RTMP streams are correctly detected when there
is a |RtmpSampleAccess object prior to the onMetaData object.
I suppose that’s okay. It’s in the input stream as well after all.
