Django Celery FFMPEG : convert video files
3 janvier 2012, par sultanI'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 getflv_movie.flv
file but its size is only about200Kb
and debug outputPress [q] to stop, [?] for help
[h264 @ 0x10205a200] Reference 3 >= 3

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 VictorI 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 ?
