Python, mencoder, mplayer help

[Drakx]

Hi

as you know i'm trying my hardest to give quickrip life again ive fixed all seeable bugs just one section of code to do with mplayer/mencoder as im not too familiar with mencoder/mplayer im hoping some one will help me out till i get the hang of mencoder/mplayer the code that is not working is below:

What exactly is not working? What are the symptoms? Are there error messages, or does something fail to happen that you expect to happen?

that section of code is not ripping the tracks ie video and audio how ever quickrip seems to think it has done its job in 2 secs flat!! here is the cli out put


QuickRip will now rip the following tracks:
- Track 1 (/home/drakx/THE_MUMMY_RETURNS_UK-1.avi) at 638kbps
Hit enter to begin ripping, or 'b' to return to the main menu
>


* Ripping title THE_MUMMY_RETURNS_UK-1 (1 of 1)
audio | 100% |================================================= ===========|
video | 100% |================================================= ===========|

* Ripping complete. Hit enter to return to the main menu



what is suppose to happen is quickrip is suppose to run mplayer what i mean is this

nice -n 3 mencoder -oac mp3lame -lameopts mode=2:cbr:br=128:vol=0 -ovc frameno -o frameno.avi dvd://1

for mp3 audio ripping and video some thing like this

nice -n 3 mencoder -sws 2 -oac copy -ovc lavc \
-lavcopts vcodec=mpeg4:vbitrate=657:vhq:vpass=1 \
-ffourcc XVID dvd://1 -o /dev/null

also


nice -n 3 mencoder -sws 2 -oac copy -ovc lavc \
-lavcopts vcodec=mpeg4:vbitrate=657:vhq:vpass=2 \
-ffourcc XVID dvd://1 -o "movie.avi

ive run these commands in a terminal and they work how ever when i try to put them commands into quickrip, it thinks its that quick it can do a 2 hour in 2 secs flat (timed) and there is nothing produced no video/audio :-| ](*,)

any ideas you can provid will be great

Well, have you tried just printing out the command lines the program thinks it's executing? That way you can compare it with the commands you would normally type in so you can see what is going wrong.

[Drakx]

this the command quickrip runs to rip audio

lameopts = "".join(["cbr=", str(title['abr']), str(vol)])
arguments = ["-dvd", str(title['id']), "-alang", title['alang'], \
"-oac", "mp3lame", "-lameopts", lameopts, "-ovc", "frameno", "-o", \
os.path.join(self.config['outputdir'], "frameno.avi")]
# Run mencoder
self.run('mencoder', arguments, self.mencodeFinished, self.mencodeProgress, \
flushbuffer=1, data="audio")

no matter what i do for some strange reason just wont run i know that
nice -n 3 mencoder dvd://# options

is needed in the mplayer pre realeses but even when i try put the above "nice -n 3" section the same thing happens

Sorry, I guess I wasn't as clear as I could have been. I don't have the whole program in front of me, so I can't see what the self.run() method is doing. I meant, if you drill down far enough, the program must be doing an os.system() or a popen() type of call to interact with the operating system. My suggestion was that you put diagnostic code at this point and print out the exact command line after all the string mangling has been done. Then you can consider scenarios like: Is a relative command line being used? If so, what is my current working directory? Is a return status coming back? If so, what is it?
