Sorry, this part is a mistake. I start to write the patch without the
intention to send it to the list, just (in the beginning) to see how it work
all the encoding process (i would like to put something like EDL in mencoder
to eliminate commercial from captured mpeg) and i start to modify muxer_avi.c
(to avoid header information and so on) only to see if mplex get the stream
in a correct way.
After half an hour i got the stream ok so i reverse back the modification of
demux_avi.c (making the mistake, it's better just copy the original file) and
start with a new file, muxer_dump.c, copied from muxer_avi.c (there are all
the include of the original file, even if they are not needed).
As I said in the original post i don't like the way is done (if you want to
use, for examples, two audio track you can't) but i like this feature.
I send the patch to the list to have some comments for a better way to do
this job, for examples should be better put the file descriptor in the
muxer_stream_t struct (if is NULL -> use the one from the muxer_t) or select
the output filename separated by colon (so you got something like
mencoder .... -of dump -o capt.m2v,capt.ac3
mencoder ... -of dump -o capt.m2v,capt.eng,capt.it
) but this requires a better understanting of the whole mencoder and of the
unix / linux way of doing things (as i said in another mail i come from other
(un)operating system and i'm learning new way of programming).
> I don't see much sense in this.. there were such patches for mplayer
Is to avoid to have a patched mplayer (that don't write the packet size of
every block) and to have to call it twice (in the beginning was once mplayer
to have the video stream and once ffmpeg to convert from PCM to ac3) to have
the stream to feed to mplex one of the reason i done the patch (the other was
to understand better mencoder).
I actually use it in the encoding part of the DVD so i would like to have it
integrated in the mencoder source, this may be useful even to other person
that makes DVD or SVCD or other formats (if you have the 'clean' stream you
can write your own muxer program).
