  • 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)

    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 ?

  • ffmpeg - wrong length of video

    29 mars 2012, par Victor

    I use ffmpeg to convert a video from mp4 to flv and mpg formats. Just rough conversion with few params :

     ffmpeg -i my_file.mp4 -an -f flv my_new_file.flv

    (I don't need sound so I specified -an)

    When I convert file with 2:23 length I get 0:23 length of flv(or mpg) files. Why does that happen ?
