  • Django Celery FFMPEG : convert video files

    3 janvier 2012, par sultan

    I'm trying to convert video files using FFMPEG via Celery tasks. The generated command to be executed looks like

    ffmpeg -i /path/to/flv -ar 22050 -ab 96k -r 24 -b 600k -f flv path/to/flv/transcoded/flv_movie.flv

    and when I call the task TranscodeVideoTask.delay(src=filepath, dst=destination_path)
    I get flv_movie.flv file but its size is only about 200Kb and debug output

    Press [q] to stop, [?] for help
    
[h264 @ 0x10205a200] Reference 3 >= 3
    
[h264 @ 0x10205a200] error while decoding MB 7 5, bytestream (690)

video:114kB audio:20kB global headers:0kB muxing overhead 1.814991%

    TranscodeVideoTask source

    @task(name="transcode.media")
    
def TranscodeVideoTask(src, dst):
    
    command = commands.get("flv") % {"src": src, "dst": dst}
    
    os.system(src, dst)
    
    filename = os.path.join(dst, "flv_movie.flv")
    
    YamdiInjector.yamdi(filename, dst)

    When the same command executed manually in the console it works just fine.

    UPDATE
    So far I've composed the following ffmpeg instructions in my bash file and it converts almost every avi file I tested already

    #!/bin/sh
    
INPUT=$1
    
OUTPUT=$2/flv_movie.flv
    

    
echo "Input file: ${INPUT}"
    
echo "Output file: ${OUTPUT}"
    
echo `ffmpeg -y -i $INPUT -ar 44100 -ab 128k -ac 2 -sameq -f flv $OUTPUT`

    What may cause this strange problem ?

  • Web video timecode seek

    17 mars 2012, par David542

    On Youtube, you can seek to a particular video time, this is usually accurate to within one second.

    I am trying to set up something similar (JWPlayer) has a plugin to allow seeking to a particular time), however it is usually about ten seconds off. Does this have to do with the spacing of keyframes, or how would I accomplish a better accuracy, like that done by YouTube ? What encoding parameter do I need to look at ?
