[0x8d42554] stream_out_standard stream out error: no mux specified or
found by extension
[0x8d42134] main stream output error: stream chain failed for
`standard{mux="",access=""#duplicate{dst="transcode{vb=400}",dst="std{access=file,mux=avi,dst=testing.avi}",dst="std{access=http,mux=mpjpeg,dst=localhost:11300}"}""}'
Notice the addition of `standard{mux="",access='' ' before the
`#duplicate' . I think --sout adds a default combination if it doesn't
find a proper argument. Unfortunately, I know a bit less about vlc
command line arguments than I do about Python's generation of those
arguments.... ;)
I had originally patched together the vlc command line from examples on
the web. I think I'll go back and refamiliarize myself with vlc's
command line and see if I can interweave my new understanding of how
Python creates arguments with some further vlc knowledge.
Thanks a bunch for the help. If you get an epiphany, I'm always open to
suggestions.... ;)
