  • Generating movie from python without saving individual frames to files

    8 avril 2015, par Paul

    I would like to create an h264 or divx movie from frames that I generate in a python script in matplotlib. There are about 100k frames in this movie.

    In examples on the web [eg. 1], I have only seen the method of saving each frame as a png and then running mencoder or ffmpeg on these files. In my case, saving each frame is impractical. Is there a way to take a plot generated from matplotlib and pipe it directly to ffmpeg, generating no intermediate files ?

    Programming with ffmpeg’s C-api is too difficult for me [eg. 2]. Also, I need an encoding that has good compression such as x264 as the movie file will otherwise be too large for a subsequent step. So it would be great to stick with mencoder/ffmpeg/x264.

    Is there something that can be done with pipes [3] ?

  • Re-Stream a MPEG2 TS PAL Stream with crtmpserver

    2 octobre 2011, par mblaettermann

    I want to build up some kind of stream wrapper :

    I own an old Dreambox PAL Sat Reciever with Networking. This stream I want to transcode to a lower resultion an restream it.

    My Goal is, to have a simple website, where this stream is embedded via rtmp.

    I thougt crtmpserver should be the right software. For now I have a site running and can play local files through jwplayer/crtmpserver.

    I am looking for a solution for this :

    httpUrl -> ffmpeg -> crtmpserver

    Is that possible ? May I redirect the output of ffmpeg to a filed pipe, and crtmpserver could grab that ? Or go with UDP ?

    Any hints appreciated !!! Thanks !!

  • Any way to assign terminal output to variable with python ?

    12 août 2016, par Gordon Fontenot

    I need to grab the duration of a video file via python as part of a larger script. I know I can use ffmpeg to grab the duration, but I need to be able to save that output as a variable back in python. I thought this would work, but it’s giving me a value of 0 :

    cmd = 'ffmpeg -i %s 2>&1 | grep "Duration" | cut -d \' \' -f 4 | sed s/,//' % ("Video.mov")
    
duration = os.system(cmd)
    
print duration

    Am I doing the output redirect wrong ? Or is there simply no way to pipe the terminal output back into python ?
