    I use ffmpeg. As far as I know, it's CLI. So it'd be like
    Code:
    ffmpeg -i NameOfVid.avi NameOfVid.3gp
    Doesn't have to be avi though. Haven't ever converted to 3gp but it's worth a try for you

    Hi,

    If you wanted 3gp files with aac sound and h263 video the straight commandline FFmpeg should be your friend. Simply follow the directions on this page to get the most out of your copy of FFmpeg:

    Unfortunately I don't know enough about WinFF to offer any guidance with it .

    Guidance on WinFF in this context is easy. If your ffmpeg can do it, winff can do it. @gigaferz, your ffmpeg did not have amr_nb build in. Which version of Ubuntu are you running? If Intrepid or newer, do you have libavcodec-unstripped-51 or -52 installed, or just libavcodec5X (I think you need the unstripped version)?

    Re: convert video to 3gp

    @ ken do san,
    i tried it but it gives me a segmentation fault
    not even the wine version works
    @ andrew
    I ve been trying that (looks like ffmpeg is ok) but it always gives me a bitrate error or incorrect framesize , from commands copied and pasted from websites

    and that software just expired, and me as usual with no cash, lol
    @ paul
    i have the unstripped version

    I KNOW so far :
    video codec h263
    video fps 15
    video size 176x144

    audio codec libmp3lame,ac3
    audio bitrate 64 (however ive seen 10.200?)
    audio frequncy 8000

    Im gonna try mpeg4 as a video codec to see if this works.... thanks for your help

    this is an error i got

    could not find tag, codec not currently supported in container
    Could not write header for output file #0 (incorrect codec parameters ?)

    this is my command line so far
    ffmpeg -i 1.flv -vcodec mpeg4 -s 176x144 -r 15 -b 100k -acodec libmp3lame -ac 1 -ar 8000 1.3gp

    same with errors with h263

    Re: convert video to 3gp

    3gp is simply a container format so you can stick any audio and video codec in. All of my mobile videos have mp3 or m4a sound and they play just fine. If you post what you want from the video we can suggest something? For me it's usually

    Code:
    ffmpeg -i input.flv -b 300k -s 320x240 -vcodec mpeg4 -ac 2 -ab 128k -acodec libfaac output.3gp

    Re: convert video to 3gp

    I don't know, that bottom command looks pretty accurate, I would guess something to do with the mp3 audio and codecs, especially if mpeg4 works in the command I posted.

    It could have also been a dodgy video you tried to encode

    edit: yeah 320x240 is the right size for my phone but as usual it varies
