FFMPeg Revision

Just curious to when we can convert our nice vob files that we now can host under SFS2 partitions... wanting to convert my 6.7Gig Princess Bride into an avi I can then store on my Modded Xbox... to my horror some audio codecs is missing...

help ;)

ffmpeg -i PB.vob -f avi -vcodec mpeg4 -b 800k -g 250 -bf 2 -acodec mp3 -ab 128k PB.avi

I reluctantly tried mencoder and was kindly informed that it didn't support mp3...

I know it seems to be a problem... but any update in this area?

thanks!

another ffmpeg thread exists but that looked like it dealt more with the gui... I like the shell also :D

At the moment ffmpeg lacks faac audio support, as faac and libfaac have only just been ported to OS4.
Kevin (KTadd) stated that ffmpeg needed to be re-compiled to include support for them, before they could be used.

This means that converting files to mp4v (ipod) format can only be done without audio. Are you using aac audio format?

Looking at this page,
DVD is mpeg2 compression for both video and audio, and DivX is mpeg4 for video, and mp3 for audio. Which should give you your .avi file.

Your input file shows three audio streams?
Do you know what they are?
Maybe it is one of them that is not supported?

Also what is your shell input line, can you force mp3, or another audio format to work?

Sorry if the above is more questions than answers, but I am only learning about this stuff myself.

I do appreciate the interest and yes I did try the map feature to select the different audios...

-map 0:0 0:2 for instance

I think maybe I need to do some serious reading... I don't mind manuals etc, it's just finding the right information first that is quite the problem :D

the complete input line is clearly in my initial post... I don't think one can force anything if the program can't identify what it is it is supposed to read and understand first let alone go on to convert it :D

Although you probably already have those if you are using the shell.

Have you tried to just simplify your input and see what happens. something like:-
Quote:
ffmpeg -i filename.flv -b 300 filename.avi
If that works you could then add in the various settings to see what happens.
I have used ffmpeg -i path/filename to find out the details of files created with ffmpeg, which again might be a source of info.

I have just looked at the ffmpeg FAQ, and the following might be helpful
Quote:
2.7 Why does FFmpeg not decode audio in VOB files?

The audio is AC-3 (a.k.a. A/52). AC-3 decoding is an optional component in FFmpeg as the component that handles AC-3 decoding is currently released under the GPL. Enable AC-3 decoding with ./configure --enable-gpl. Take care: By enabling AC-3, you automatically change the license of libavcodec from LGPL to GPL.


I am not sure as to whether this is a compile option, or a usage option, but at least it refers to your problem.

Thanks again there Swoop... yip, I tend to live in a shell :D and I think that latter suggestion is a compile option...

I will try the simplified approach but as far as I can tell my only options are this... seperate the audio and convert it into raw or aiff or what not and then use FFMPeg to take only the video from the MPeg DVD Vob and merge with the new audio... the complication involved in this is getting the audio bit rate in sync I suppose... not sure I'm prepared to knock myself out over this... lol

I was reading in another thread on here that the neccessary support had been implemented but wasn't publically available since it caused other problems in other support namely cell phone formats??

I'd like to get my hands on that since I wouldn't use FFMPeg to convert anything else but vobs :D

lets see that ;) heh

One thought I had was that you could try the ac3 audio format instead of forcing it to mp3. That might be where the problem is.
I have a small VOB file I recorded from the TV, If I get time later on today, I'll copy it to my hard drive and have a play.

Using the following,
Quote:
ffmpeg -i Media:Videos/TV.VOB -f avi -vcodec mpeg4 -acodec ac3 PB.avi
I get
Quote:
Media:Videos/TV.VOB: could not find codec parameters
I get the same result if I just use
Quote:
ffmpeg -i Media:Videos/TV.VOB

You could just rename the VOB files from PB.VOB to PB_01.avi & try avisplice on os4 depot to make one big file. I'm assuming there's more then 1 VOB video file. At least dvplayer & mplayer will play the renamed video.

Look, only one leg, count em, one!

not a bad idea, I'll try that soon... might cause some problems with bitrate? since the resulting avi will be smaller... which would again lead to the problem of trying to load in the original audio and manipulate it...

@sundown

not sure what you are solving here but thanks for the thoughts... I have no problem storing the large file... I already joined the 7 vob files in total to one file in a SFS2 partition that supports files larger than 4 gig...

PB.vob is 6.7 gigs - used cat to join it

:D
