  • gstreamer rtsp streaming chain with LGPL elements

    25 avril 2016, par user3612009

    The following chain seem to work well to stream video :

    gst-launch filesrc location=/home/manusha/Downloads/movies/<movie file="file">.mkv ! decodebin ! ffenc_mpeg4 bitrate=5000000 ! rtpmp4vpay mtu=1400 pt=96 ssrc=0 timestamp-offset=0 seqnum-offset=0 send-config=true ! udpsink host=127.0.0.1 port=5000
    
</movie>

    This chain is able to receive the stream and play it :

    gst-launch udpsrc uri=udp://127.0.0.1:5000 caps="application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)MP4V-ES, profile-level-id=(string)1, config=(string)000001b001000001b58913000001000000012000c48d88007d0a041e1463000001b24c61766335322e3132332e30, payload=(int)96, ssrc=(uint)298758266, clock-base=(uint)3097828288, seqnum-base=(uint)63478" ! rtpmp4vdepay ! ffdec_mpeg4 ! autovideosink

    My problem is, both ffdec_mpeg4 and ffenc_mpeg4 are GPL licensed and will not suit my purpose because I need to redistribute them. I am lookiing for advice on alternative stream chains that I can form only with LGPL licensed elements. The streaming to be used only inside a LAN, but it need to support HD quality streaming.

  • Transcoding video using ffmpeg from the internet or over http

    19 juillet 2015, par Robin

    I have a project for transcoding videos. Right now I am passing the absolute path of the video as the input variable, as such :

    inputfile = str(MEDIA_ROOT)+'/'+str(video.original_video)

    Here the MEDIA_ROOT is /home/user/code/Project/Viu/static/media

    And then

    subprocess.call(
    
        'ffmpeg -i '+ inputfile +' -codec:v libx264 -crf 23 -preset faster -codec:a libfdk_aac -vbr 4 \-movflags faststart -vf scale="720:trunc(ow/a/2)*2",format=yuv420p '+ outputfile,
    
        shell=True
    
    )

    This is ok for now. But I will be keeping those videos on different location from the server, how can I convert videos from that location over the internet or http?

    I tried this :

    inputfile = 'http://localhost:8000/media/'+str(video.original_video)

    But I get this error :

  • Compiling FFMPEG on CentOS DigitalOcean

    29 juillet 2015, par coder_uk

    I set up a DigitalOcean instance running CentOS 6.5 and successfully followed the guide to compile FFMPEG (https://trac.ffmpeg.org/wiki/CompilationGuide/Centos). Hurrah !

    But of course I realised that by default, DigitalOcean creates a root user and so ffmpeg now lives in /root/bin/ffmpeg. Which isn’t ideal because when I want to exec the ffmpeg bin from nginx, I would have to run nginx as root for it to have permission.

    Questions ...

    1) Long-shot, but presumably if I change the owner of the ffmpeg binary to nginx, it still won’t work, because nginx won’t be able to access the /root folder it is in. Correct ?

    2) I could run nginx as root (’user root’). But this seems like a very bad idea. Correct ?

    3) Which leaves me with the option of creating a new user, and then compiling ffmpeg into its home folder. But : which user ? EC2 creates ’ec2-user’, so should I make my own equivalent for DO ? But then won’t I have to run nginx as that user, else I’ll run into the same problem ?

    Or should I compile ffmpeg into the ’nginx’ home folder, if indeed it has one ? Is that how it is supposed to be done ?

    Since compiling ffmpeg takes ages, I don’t want to keep doing it, and the static files all seem very out of date. Thanks
