  • ffmpeg on ubuntu convert 3gp to iphone 5 format [closed]

    21 mars 2013, par Jistanidiot

    I'm desperately trying to convert a 3GP video into something the iphone 5 will import and play. Verizon says they cannot help me that it is not possible to convert a Droid video to iphone.

    After much trouble I came to the conclusion to try the conversion on my Ubuntu box using ffmpeg. Again after a long struggle, I removed the package and followed the directions at https://ffmpeg.org/trac/ffmpeg/wiki/UbuntuCompilationGuide

    Now with the new complied ffmpeg, I try the following command :

     ffmpeg -i foo.3gp -s 320x240 -r 30000/1001 -b:v 200k -bt 240k -vcodec libx264 -coder 0 -bf 0 -flags2 -wpred-dct8x8 -level 13 -maxrate 768k -bufsize 3M-acodec libfaac -ac 2 -ar 48000 -ab 192k output.mp4

    However I keep getting the error :

     [NULL @ 0xa9874a0] Unable to find a suitable output format for 'libfaac' libfaac: Invalid argument

    I found a random blog post saying you needed to add

    `-target type’

    and then specify target file type (“vcd”, “svcd”, “dvd”, “dv”, “dv50”, “pal-vcd”, “ntsc-svcd”, … ). However after trying all 8 of them listed I still got the same errors.

    I'm at a complete loss. How can I convert the 3gp video into the iphone 5 format ?

    Thanks in advance.

  • Segmenting video into different parts and unique rendering on each part then concat afterwards

    2 mars 2016, par goudarziha

    I currently have a very poorly performing application that splits up a video, renders it and the concats all rendered videos on android using ffmpeg

    So I am running into issues with segmenting a video up into 5 parts at each different intervals/durations, rendering each video segment uniquely slowing up/speeding up and then finally concat all the segments back into one final video.

    Currently I am doing each part separately -

    Segmenting -
    example for one segment
    -y -i pathIn -ss 0.0 -t 2.0 -vcodec copy -acodec copy -an pathOut

    Rendering - example slowing down/speeding up

    - y -i path -filter:v setpts=2.0*PTS pathOut

    Concat -

    - f concat -i input1.mp4 -i input2.mp4 -i input3.mp4 -i input4.mp4 -i input5.mp4 -c copy output.mp4

    Right now I am running different separate thread for each editing of video, so 3, segment, rendering and concat.

    I am trying to get this all done on one command ffmpeg line if at all possible, if not just the segmenting and rendering of the videos and kick of the concat cmd line later.

    I am trying to emulate something similar to this https://trac.ffmpeg.org/wiki/Creating%20multiple%20outputs
