  • Split single video input files into 30 second blocks

    6 juin 2016, par Ycon

    I am trying to split several video files (.mov) into 30 second blocks.

    I do not need to specify where the 30 seconds start or finish.

    EXAMPLE- A single 45 second video (VID1.mov) will be split into VID1_part1.mov (30 seconds), VID1_part2.mov (15 seconds). Ideally, I can remove audio too.

    I made an attempt, using bash (osx), but was unsuccessful. It did not split the video into multiple parts- instead it just seemed to modify the original file (and made it into a length of 1-2 seconds) :

    find . -name '*.mov' -exec ffmpeg -t 30 -i \{\} -c copy \{\} \;

  • Linux job queue for FFmpeg conversion [closed]

    3 février 2013, par Rik Bauwens

    I'm starting up a Debian web server which will host a website where users can upload video files and play them.

    Hence, the video files need to be converted into the proper format (mp4, ogg, webm) for compatibility with the different browsers out there.

    So far, I've written a bash script which does the trick using FFmpeg. The problem is, when a lot of users upload a video at the same time, my web server will get very slow.

    I'm looking for a short and easy solution which queues different calls to the conversion script, so only one instance can run at the same time. I've tried using the batch command, but I can't find very much information on how to use it. I've also considered creating a named pipe, also without success.

    Any help much appreciated

  • Call ffmpeg in c++ with system() function fails

    2 septembre 2014, par zhen lee

    I write a c++ program which needs to convert some(say:10) mp4 videos to flv videos.
    I use ffmpeg in my program for each video like this :

    system("ffmpeg -i video -filter:v yadif -ar 44100 -sameq -y -f flv temp.flv")

    however,it turns out :only first video will be converted successfully,the others will fail.
    it means :
    when i change the input order of which video to convert and re-execution the program,it behave the same:only the first video(will be different each time as i changed the input video order) will be converted successfully.

    The error message like :

    [h264 @ 0xaee0740] concealing 45 DC, 45 AC, 45 MV errors
    [h264 @ 0xaee0ce0] AVC : nal size 305665
    Last message repeated 1 times
    [h264 @ 0xaee0ce0] no frame !

    [aac @ 0xad9ccc0] channel element 0.13 is not allocated
    Error while decoding stream #0:1
    [aac @ 0xad9ccc0] channel element 0.13 is not allocated
    Error while decoding stream #0:1
    ......
    The most strange thing is :when i run ffmpeg command in bash shell,all video will be converted successfully .

    After google it,I have try these(certainly failed) :

    1. remove -sameq option,the result is same ;

    2. write ffmpeg commod in a shell script ConvertToFlv.sh like :

      /usr/local/bin/ffmpeg -i "$dir/$1" -filter:v yadif -ar 44100 -sameq -y -f flv "$dir/temp.fiv"

      then call this script in program like

      system("ConvertToFlv.sh"+video)

      or

      system("sh ConvertToFlv.sh"+video)

      The result is same.

    The ffmpeg configure is :
