I have tried a few methods of executing ffmpeg from within python and it has
hanged every time. Two of the configurations I tried are:
def convertFileToFlash(filename):
commandString = "./convertasftoswf.sh " + getSaveDirectory() + " " +
filename
logging.debug("RUNNING: " + commandString)
results = commands.getstatusoutput(commandString)
logging.debug(results)
convertasftoswf.sh:
#!/bin/sh
mencoder ${1}${2} -o ${1}outputfile.avi -ovc xvid -xvidencopts
bitrate=280:max_bframes=0 -oac mp3lame -lameopts mode=0:cbr:br=128 -vf-add
scale=320:240,expand=320:240 -vf-add harddup -ofps 25.00 -srate 44100
chmod 777 ${1}outputfile.avi
ffmpeg -i ${1}outputfile.avi ${1}${2}.swf
Also, I tried running each of the commands (mencoder and ffmpeg) separately
with the commands.getstatusoutput from within python.
Then mencoder call always runs without a problem and the ffmpeg always
hangs. Running the shell script directly from the command line works as
expected.
Any ideas about why ffmpeg would hang in that situation?
Thanks.
