  • ffmpeg make : *** No rule to make target 'distclean'. Stop

    11 octobre 2016, par Djave

    I’m installing ffmpeg using this guide https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu on a Digital Ocean droplet.

    I’ve run all the commands down to

    $ make distclean

    and after I do this I get the error

    make: *** No rule to make target 'distclean'.  Stop.

    How can I get past this step ?

  • Issue when streaming some TV channels threw ffMpeg

    7 octobre 2016, par Raphael Serievic

    I am trying to stream a TV Tuner feed with ffMpeg through udp.

    The ffMpeg command line I use is the following :

    ffmpeg.exe -i udp://@239.255.255.9:1234 -map 0:p:1317:0 -profile:v baseline -crf 30 -preset ultrafast -vcodec libx264 -r 25 -vf scale=720:576-b:v 500k -f rtp udp://10.150.112.107:15048/ -map 0:p:1317:1 -acodec pcm_mulaw -strict experimental -ar 8k -ac 1 -b:a 128k -f rtp udp://10.150.112.107:15032/

    Where :

    • 1317 is the program id (channel)
    • 10.150.112.107 is where I want to stream the TV channel
    • 239.255.255.9 is where I receive the original TV channel’s feed from my TV Tuner

    My problem is that with some program IDs it is working and with some others it is not : it is working with 1572 ("channel 10 hd") but not with 1317 ("7flix Sydney").

    The output of this command-line for channel 1572 (where it works) is the following :

    C:\Program Files (x86)\Tuner Manager\ServerModule> ffmpeg.exe
    -i udp://@239.255.255.7:1234 -map 0:p:1572:0 -profile:v baseline -crf 30 -prese

    I finished up at Google last week and am now working at NICTA, an Australian ICT research institute.

    My work with Google was exciting and I learned a lot. I like to think that Google also got a lot out of me – I coded and contributed to some YouTube caption features, I worked on Chrome captions and video controls, and above all I worked on video accessibility for HTML at the W3C.

    I was one of the key authors of the W3C Media Accessibility Requirements document that we created in the Media Accessibility Task Force of the W3C HTML WG. I then went on to help make video accessibility a reality. We created WebVTT and the <track> element and applied it to captions, subtitles, chapters (navigation), video descriptions, and metadata. To satisfy the need for synchronisation of video with other media resources such as sign language video or audio descriptions, we got the MediaController object and the @mediagroup attribute.

    I must say it was a most rewarding time. I learned a lot about being productive at Google, collaborate successfully over the distance, about how the WebKit community works, and about the new way of writing W3C standard (which is more like pseudo-code). As one consequence, I am now a co-editor of the W3C HTML spec and it seems I am also about to become the editor of the WebVTT spec.

    At NICTA my new focus of work is WebRTC. There is both a bit of research and a whole bunch of application development involved. I may even get to do some WebKit development, if we identify any issues with the current implementation. I started a week ago and am already amazed by the amount of work going on in the WebRTC space and the amazing number of open source projects playing around with it. Video conferencing is a new challenge and I look forward to it.
