  • Run ffmpeg without outputting configuration information ?

    28 mars 2014, par Matt Joiner

    I'm invoking ffmpeg with subprocess.Popen, and trying to capture the stderr output and write it to logging.

    args = ['ffmpeg', '-i', path]
    
if start:
    
    args += ['-ss', start]
    
if end:
    
    args += ['-t', end]
    
args += [
    
    '-vcodec', 'copy',
    
    '-acodec', 'copy',
    
    '-scodec', 'copy',
    
    '-f', 'mpegts',
    
    '-y', '/dev/stdout']
    
self.child = subprocess.Popen(
    
    args,
    
    stdin=open(os.devnull, 'rb'),
    
    stdout=subprocess.PIPE,
    
    stderr=subprocess.PIPE)

    ffmpeg generates a lot of configuration information like the following :

    Is there an option to prevent this excessive output ? Should I be doing it differently ?

  • keepalive type and frequency in ffmpeg [on hold]

    19 novembre 2013, par Jack Simth

    My company has a bunch of IP cameras that we distribute - specifically Grandstream - and the manufacturer has changed their firmware. The normal keepalive that ffmpeg uses for the rtsp streams ( either ff_rtsp_send_cmd_async(s, "GET_PARAMETER", rt->control_uri, NULL) ; or ff_rtsp_send_cmd_async(s, "OPTIONS", "*", NULL) ; both in in libavformat/rtspdec.c) is no longer working, for two reasons :

    1) The new Grandstream firmware is now checking for a receiver report to determine whether or not the program reading the stream is live, not just anything.

    2) The new Grandstream firmware requires that the receiver report to keep the connection alive happen at least once every 25 seconds, and on the audio stream it is currently only happening about every 30 seconds or so (video is getting it every 7 seconds or so).

    So after about a minute with ffmpeg connected, the camera stops sending the audio stream, the audio stream on ffmpeg reads end-of-file, and then ffmpeg shuts everything down.

    As I can't change the firmware, I'm trying to dig through the ffmpeg code to make it send the appropriate receiver report for the keep alive... but I am getting nowhere. I've added a little snippet of code into the receiver reports so I know when they're running when I call ffmpeg on debug, but... well, it's not going well.

    Test command :
    ffmpeg -loglevel debug -i rtsp ://admin:admin@192.168.4.3:554/0 -acodec libmp3lame -ar 22050 -vcodec copy -y -f flv /dev/null &> test.txt
