Anyone successfully encoding video with VLC on OS X?

[Bill Tuttle]

I've installed the latest VLC. The command I'm using is:

vlc --intf=rc /rockbox/gigabeat-sim/archos/movies/test.mp4 --sout=#transcode{vcodec=mp2v,vb=600,width=320,height=240,acodec=mp3,ab=128,samplerate=44100,audio-sync}:std{access=file,mux=ps,url=/rockbox/test.mpg}

And I get:

[00000031] main interface error: no interface module matched "hotkeys,none"
[00000031] main interface error: no suitable interface module
[00000001] main private error: interface "hotkeys,none" initialization failed
[00000000] main root error: option equalizer-preset does not exist
[00000000] main root error: option equalizer-preamp does not exist
[00000000] main root error: option equalizer-bands does not exist
[00000036] main private error: no sout stream module matched "transcodeaudio-sync"
[00000035] main stream output error: stream chain failed for `transcodeaudio-sync:stdurl=/rockbox/test.mpg'
[00000033] main input error: cannot start stream output instance, aborting
[00000029] main playlist: nothing to play

Anyone had any success encoding video on OS X? Even with another tool? Thanks.

update: I also just tried to do it from within the regular app version of VLC, rather than the command line. I get:

ffmpeg: cannot open encoder
stream_out_transcode: cannot find encoder ((null))

You forgot the quotes around the transcode option value. In a shell it will expand stuff like a{b,c}d to abd acd. So you need to make sure that the quotes are there to prevent that from happening.

Thanks.

Like so?

vlc --intf=rc /rockbox/gigabeat-sim/archos/movies/test.mp4 --sout="#transcode{vcodec=mp2v,vb=600,width=320,height=240,acodec=mp3,ab=128,samplerate=44100,audio-sync}:std{access=file,mux=ps,dst=/rockbox/test.mpg}"

I get the same results... Hmm.

[dionoea]

That seems highly unlikely. Can you paste the new debug info? You could also try changing the equal sign right after --sout to a space, i don't know if that matters (I never use equal signs on Linux but I know that they're needed on Windows).

$ vlc --intf=rc /rockbox/gigabeat-sim/archos/movies/test.mp4 --sout "#transcode{vcodec=mp2v,vb=600,width=320,height=240,acodec=mp3,ab=128,samplerate=44100,audio-sync}:std{access=file,mux=ps,dst=/rockbox/test.mpg}"

^Csignal 2 received, terminating vlc - do it again in case it gets stuck

Also tried single quotes.

I'm kind of clueless here. Might be due to the fact that you need to use "VLC.app/Contents/MacOS/clivlc" when launching VLC stuff command line on Mac OS X. If that still doesn't work, can you paste the full debug (add -vvv --color) to your command line. (You can paste it on http://paste.videolan.org and provide a link here so that it gets the appropriate colors)

I encode with ffmpegx. can get a bit complicated, but otherwise lots of options so you can basically encode whatever into whichever.

[Bill Tuttle]

Thanks all - the clivlc is just a symlink to vlc. They're in the same folder. However, it does act differently (just tried it). Here's a link to the full debug dump:

I'll take a look a ffmpegx and see what I can do. Thanks.

etien - thanks for the ffmpegx info. I just successfully re-encoded a video podcast out of iTunes and it runs on Rockbox. (Well, it's actually running in a F40 simulator).
