  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • Alternative to sws_scale

    19 décembre 2012, par Hrishikesh_Pardeshi

    I am performing encoding of the captured windows screen with x264 using libavcodec. Since, the input is RGB, i am converting it to YUV to make it compatible with x264. I am using the sws_scale function for the same.
    My question is if there is any alternate for this function since i don't need any scaling to be done in my case. Also, it would be useful if someone could throw light on the workflow of this function.

    P.S : I am assuming x264 operates only in YUV color space. If this assumption is incorrect, please inform me on the same.

    Thanks in advance.

  • avconv with subprocess

    17 juillet 2012, par Niclas Nilsson

    It's seems like I never really manage to wrap my head around subprocess. This commandline works in bash

    avconv -i "concat:/tmp/BABAR_AND_THE_A-011A-hts-a-v1-cc3651d01841d748_Layer6/6148_Period1/segment0.ts|/tmp/BABAR_AND_THE_A-011A-hts-a-v1-cc3651d01841d748_Layer6/6148_Period1/segment1.ts" -vcodec copy -acodec copy /tmp/test1.ts

    Bu if I try this :

    cmdline = ['avconv', '-i "concat:/tmp/BABAR_AND_THE_A-011A-hts-a-v1-cc3651d01841d748_Layer6/6148_Period1/segment0.ts|/tmp/BABAR_AND_THE_A-011A-hts-a-v1-cc3651d01841d748_Layer6/6148_Period1/segment1.ts"', '-vcodec copy', '-acodec copy', '/tmp/test1.ts']
    subprocess.call(cmdline)

    It exit avconv with the following error :

    I've tried some variants (including shell=True) but I can't figure out the problem.

    Update

    Cjb made an answer that really worked. But my real code is more complicated. I believe it's hard to get something out of it. But I throw it in here just in case there is an obvoius problem that I missed.

    def run_avconv(output_dir, fnames):
       full_fnames = [os.path.join(output_dir, fname.replace('\n', ''))
                      for fname in fnames]
       concatted_files = '|'.join(full_fnames)
       cmd_line = [AVCONV_CMD,
                   '-i',
                   '"concat:' + concatted_files + '"',
                   '-vcodec',
                   'copy',
                   '-acodec',
                   'copy',
                   os.path.join(output_dir, 'out.ts')]
       subprocess.Popen(cmd_line)

    the full_fnames variable is :

  • Emulate an IP Camera

    23 décembre 2013, par Goro

    I am using software (DVR) that is meant to talk directly to an IP camera. I am trying to pass a h264 stream directly into it, but it does not work if I just throw a stream onto it.

    Can you recommend any "spoofing" software to emulate an IP camera ? For the sake of argument, we can say that the camera we want to emulate is Axis P3301.

    Given that a lot of software out there can talk to IP cameras, is there a way to use something like vlc/ffmpeg to look like its an IP camera ?

    Thanks.
