I did leave out some "empty channels" to simplify and clean up the
post. Here are the full ffprobe output for the HDV source
(mediainfo was complete):<br>

I fogot to add that loading the HDV clip in CinGG, there is only two
visible streams:<br>
#1 (video) and #2 (stereo Audio)<br>
(That is, nothing similar to loading .mov file, where there were
additional 6 empty audio streams, #3 - #8)<br></div></blockquote></div></div><div dir="auto"><br></div><div dir="auto">yeah, no support in ffmpeg, no support in libsndfile (I filed feature request) -> no additional channels!</div><div dir="auto"><br></div><div dir="auto">you need to compile decoder from source, then use it on ffmpeg-extracted mp2 file so it will generate 4 wav files.</div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div>
