  • How to determine if a ffmpeg subprocess has fallen

    9 avril 2020, par TiHan

    I have an issue

    



    I want to create a new ffmpeg process using subprocess.popen
find out his pid
and in the body of a python program to see if the process is alive or not

    



    args = shlex.split ('ffmpeg -i rtsp: //192.168.1.68: 8554 / mystream -f segment -strftime 1 -segment_time 5 13_REG1_CHANNEL3_% Y-% m-% d_% H-% M-% S-% s .mp3 ')
print (args)
proc = subprocess.Popen (args, stdout = subprocess.PIPE)
ch_pid = proc.pid
print (proc.pid)
proc.wait ()
print (proc.communicate ())
while (1):
 if (os.system (str ('kill -0 {PID}'). format (PID = ch_pid)) == 0):
   print ('proc is alive')
 else:
   break


    



    at while loop i tried to check this process pid via kill -0 pid
this command will return zero if everything is alright and process is running

    



    BUT

    



    IF ffmpeg will fall
there will be no changes

    



    kill -0 pid will continue to returning zero code that everything is good

    



    What should i do ?

    


  • Determine FFmpeg codecs available for container

    19 juillet 2020, par CasualDemon

    I am looking to generate lists of supported video / audio / subtitle tracks for each type of container in a particular build of FFmpeg.

    


    For example, I want to avoid errors like Could not find tag for codec <> in stream #0, codec not currently supported in container

    


    I know I can list available codecs with ffmpeg -codecs, and find details about a muxer with ffmpeg -h muxer=<muxer></muxer> like ffmpeg -h muxer=matroska but that will only show default codecs, not all possible.

    &#xA;

    Muxer matroska [Matroska]:&#xA;    Common extensions: mkv.&#xA;    Mime type: video/x-matroska.&#xA;    Default video codec: h264.&#xA;    Default audio codec: vorbis.&#xA;    Default subtitle codec: ass.&#xA;

    &#xA;

    Basically I want to run this command across all available muxers to build up a table like wikipedia's format comparison charts that is FFmpeg build specific. This is designed to go in a program that wraps around FFmpeg, and I need to know which formats are valid for each container / file extension per FFmpeg build.

    &#xA;

    Thanks !

  • Determine the actual resolution of a video using ffmpeg [closed]

    18 novembre 2020, par Eypros

    I am trying to decode an avi video but but when I pass it through ffmpeg to check the encoding parameters I get this outcome which confused me :

    &#xA;

    $ffmpeg -i video.avi&#xA;...&#xA;Stream #0:0(und): Video: mpeg4 (Simple Profile) (mp4v / 0x7634706D), yuv420p, 1280x720 [SAR 1:1 DAR 16:9], 2501 kb/s, 30 fps, 30 tbr, 15360 tbn, 30 tbc (default)&#xA;

    &#xA;

    I guess yuv420p means something like 746x420 pixel (I made the multiplication myself, so I am not sure it's exactly this one using the ratio of 1920x1080 and 1280x720) but anyway much less than 1280x720 which is 720p. So, what does exactly means those two together ?&#xA;yuv420p vs 1280x720 ?

    &#xA;

    Can someone explain which is the actual resolution of the video ?

    &#xA;
