  • fragmented mp4 javascript converting

    7 juin 2013, par user816004

    I wanted to know if there is a way to convert regular mp4 to a fragmented mp4 via javascript. (like mp4box does) Is it efficient enough (not suppose to be a complicated task) ? did anyone write something like this ?
    to make it harder, can it be on the fly ? meaning I will not download the whole mp4 from the server but download in parts and convert it into fragments compatible with fragmented mp4 and mpeg-dash - I'm trying to overcome to problem to not have to use 2 different file types to play a video or do mp4box on all my library in advance.

    Regardless, is it possible to convert from h.264 compatible files with different containers (mov, flv etc.) to fragmented without a server ? meaning do it in the browser with javascript somehow ?

    appreciate the help,
    Yug

  • ffmpeg Python Subprocess Error returned non-zero exit status 1

    21 avril 2019, par Varda Elbereth

    So I have a line here that is meant to dump frames from a movie via python and ffmpeg.

    subprocess.check_output([ffmpeg, "-i", self.moviefile, "-ss 00:01:00.000 -t 00:00:05 -vf scale=" + str(resolution) + ":-1 -r", str(framerate), "-qscale:v 6", self.processpath + "/" + self.filetitles + "-output%03d.jpg"])

    And currently it’s giving me the error :

    'CalledProcessError: Command ... returned non-zero exit status 1'

    The command python SAYS it’s running is :

    '['/var/lib/openshift/id/app-root/data/programs/ffmpeg/ffmpeg', '-i', u'/var/lib/openshift/id/app-root/data/moviefiles/moviename/moviename.mp4', '-ss 00:01:00.000 -t 00:00:05 -vf scale=320:-1 -r', '10', '-qscale:v 6', '/var/lib/openshift/id/app-root/data/process/moviename/moviename-output%03d.jpg']'

    But when I run the following command via ssh...

    '/var/lib/openshift/id/app-root/data/programs/ffmpeg/ffmpeg' -i '/var/lib/openshift/id/app-root/data/moviefiles/moviename/moviename.mp4' -ss 00:01:00.000 -t 00:00:05 -vf scale=320:-1 -r 10 -qscale:v 6 '/var/lib/openshift/id/app-root/data/process/moviename/moviename-output%03d.jpg'

    It works just fine. What am I doing wrong ? I think I’m misunderstanding the way subprocess field parsing works...
