Re: rm to mp3
Thanks for the help so far. I dumped the raw streaming using mplayer, and then used a 3
pass mencoder method to convert the dumped stream to avi. I would finally like to be able
to edit the video and save it to a DVD or a VCD. Here are some problems that crop up.
The 3 pass method converts source.rm to test.avi
I used transcode to encode the avi for mpeg encoding. See below for the error. The
program exits.
I played avi file using mplayer. It plays (Video and Audio). I am supposing the latter
because I have not been able to fix the sound issue with mplayer. But that later. I moved
test.avi to a windows machine and tried to play using windows media player. That just
emits sound. No video.
I am at a loss :-( Please help.
here is the o/p from transcode
-----------------
transcode -i test.avi -x avi -V -y MPEG-2enc,mp2enc -F 4 -Z 480x480 -E 44100 -b 128 -o

*** WARNING: The option -V is deprecated. ***
*** Transcode internal frame handling is now in YV12 / YUV420 ***

*** If you want to have to "old" behaviour (RGB24 as internal format), ***
