well, you can look if appimage version of cingg was compiled with those
libraries, but I am guessing (from bug
https://www.cinelerra-gg.org/bugtracker/view.php?id=590 ) you might run
into troubles trying to record exactly HDV stream - because it is not DV
video, but mpeg2. There is code in DVB input module for dealing with this,
but it probably must be wired to DV /firewire module, or something like
this should be used in ffmpeg.C for pre-decoding compressed buffer:
