ffmpeg on Linux Error - .avi to mp4

[coolboarderguy]

Hi All,

sudo ffmpeg -i /mnt/sharefat/japanese/yua/yua01.avi -vcodec mpeg4 -s 320x240 -b 300k -r 30 -acodec mp3 -ar 4800 -ab 112k -f /mnt/sharefat/japanese/yua/yua01.mpg

The file is definitely not corrupted, as it plays fine. Any suggestions? Hopefuly this is the correct forums for this.

sorry.. but you are using an mpeg4 codec in a MPEG2 container ?
better to fit it in avi or mp4

Hi All,

oops, that was a typo.


sudo ffmpeg -i /mnt/sharefat/japanese/yua/yua01.avi -vcodec mpeg4 -s 320x240 -b 300k -r 23.98 -acodec mp3 -ar 4800 -ab 112k -f /mnt/sharefat/japanese/yua/yua01.mpeg4

I am also very newbie for this stuff, although I get the concept/terminology.

[buzzqw]

again ... what is mpeg4 as output ?!

-f /mnt/sharefat/japanese/yua/yua01.avi

or

-f /mnt/sharefat/japanese/yua/yua01.mp4

HI All,

I see what you mean, the container needs to be either .avi or mpeg4. I tried both, but still getting the same error.


sudo ffmpeg -i /mnt/sharefat/japanese/yua/yua01.avi -vcodec mpeg4 -s 320x240 -b 300k -r 23.98 -acodec mp3 -ar 48000 -ab 112k -f /mnt/sharefat/japanese/yua/yua01.mp4

first off, why are you running the command as root? I won't fill up 10 pages of explaining why this is just plain flat out wrong and the worse thing a person can do. Bad, bad habit.

ffmpeg -i /mnt/sharefat/japanese/yua/yua01.avi -vcodec mpeg4 -s 320x240 -b 300k -r 23.98 -acodec mp3 -ar 48000 -ab 112k -o /mnt/sharefat/japanese/yua/yua01.mp4

ffmpeg has no clue what the format /mnt/sharefat/japanese/yua/yua01.mp4 is. That is not a format, which is what passing -f implies change that to -o for output file. If you type ffmpeg -formats, this will list the valid options for format. This switch isn't needed, in most cases, as ffmpeg will know what your doing by the extension of the output file. If you pass -o audio.ac3, ffmpeg knows to encode the audio to ac3 format.

If you need to use the sudo command to access your fat formated drive, it isn't mounted correctly, and/or you don't have the permissions set up correctly. Try the Ubuntu forums for how to correctly set up an entry in your fstab.

edit ---
depending on your version of ffmpeg, you may not need the -o command at all, so if the above doesn't work, try this

ffmpeg -i /mnt/sharefat/japanese/yua/yua01.avi -vcodec mpeg4 -s 320x240 -b 300k -r 23.98 -acodec mp3 -ar 48000 -ab 112k /mnt/sharefat/japanese/yua/yua01.mp4

Hi All,

yes, I'm aware of the root/sudo implications, I just have'nt got around to it yet. Thanx for asking, though. Below is the output I now get.

I guess there is a codec not supported with regards to audio. Which one though? Is it a generic non-supported issue or the source file issue in this case? Bit confused here.

[disturbed1]

Right click on the source file and find out what format the audio is in.

I have the same version of ffmpeg and it states that mp3 is enabled for encoding/decoding, the only common codec I noticed that is missing is aac. The avi audio file could have a wave header that is known to throw some programs off. Not sure about ffmpeg, as I rarely, if ever use it.

You could try mencoder instead. Or, just convert the audio to pcm using mencoder with this command



sudo mencoder /mnt/sharefat/japanese/yua/yua01.avi -vc copy -ac pcm -o /mnt/sharefat/japanese/yua/yua01.pcm.avi

This does nothing to the source video, and only decodes the audio wav format, then remuxes the file back to yua01.pcm.avi

then run

sudo ffmpeg -i /mnt/sharefat/japanese/yua/yua01.pcm.avi -vcodec mpeg4 -s 320x240 -b 300k -r 23.98 -acodec mp3 -ar 48000 -ab 112k /mnt/sharefat/japanese/yua/yua01.mp4

Hi All,

it says,

Audio
Bitrate: N/A
Codec: MPEG-1 layer 3

have installed mencoder. Will check it out tonight.

Hi All,

someone just doesn't love me enough. lol.

BTW, thank you all for your patience with this.

[45tripp]

how about updating to a version that's not as old as methuselah...

I don't see --enable-mp3lame

It's quite obvious 'mp3' encoding is not supported in the build you have.

ffmpeg -formats

will attest to that

Of course I see no reason to encode audio:

ffmpeg -i /mnt/sharefat/japanese/yua/yua01.avi -s 320x240 -r 23.98 -vcodec mpeg4 -b 300k -mbd 2 -flags trell -acodec copy /mnt/sharefat/japanese/yua/yua01.mp4

might as well have mencoder handy in future as you've now got it.
assuming audio encoding needed:

mencoder /mnt/sharefat/japanese/yua/yua01.avi -vf scale=320:240 -fps 23.976 -of lavf -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=300:trell:mbd=2 -oac mp3lame -lameopts abr:br=112 -o /mnt/sharefat/japanese/yua/yua01.mp4

(syntax assumes mencoder version no older than mid August 2007,
else add "-lavfopts i_certify_that_my_video_stream_does_not_use_b_fram es")
