Invalid chain?

[VirusCollector]

Hello, I'm using MediaTomb to stream things to my DirecTV receiver. So far it's worked pretty well, aside from the rampant bugs of variable bitrate.

However, when I try to stream .flv files, MediaTomb uses VLC to transcode instead of ffmpeg like it ordinarily does. I'm not sure if there's a big difference, but if it uses that, it must know what it's doing.

Here's exactly what it executes:

Code: Select all

vlc -vvv -I dummy %in --sout #transcode{vcodec=mp2v,vb=4096,canvas-width=448,canvas-height=252, acodec=mpga,ab=64,samplerate=44100,channels=1}:standard{access=file, mux=ts,dst=%out} vlc://quit

I added the -vvv parameter to try and figure out what's wrong. It keeps complaining of an invalid chain, and as far as I've researched that means the parameters are wrong. Here's the -vvv output:

Code: Select all

Just a guess... But in the debug it looks like it's only looking at the first line of the transcode, "--sout #transcode{vcodec=mp2v,vb=4096,canvas-width=448,canvas-height=252," and stopping. Perhaps put it all on one line.
