Benjamin Larsson <[email protected]> added the comment:
When dv_produce_packet/dv_extract_audio_info adds a stream for the pcm track it
doesn't add a priv_data context. Thus when the code around row 672 in avidec is
called there is no context to use when stream [1] is used. The attached patch
makes sure that stream [1] isn't used. But the file is encoded forever so this
isn't a real fix. VLC and Totem is able to play some more frames then what
FFmpeg/ffplay is able to.
