  • ffplay subscription to rtmp stream fails on first try

    2 janvier 2018, par ehouse

    I have an Electron application that does some video streaming through ffmpeg. It works fine on Windows, but I am having a small problem with it on Mac. I stream the desktop with ffmpeg, and try to subscribe to the rtmp stream. I know the rtmp stream is live because I can successfully grab a frame from it.

    The problem is, when I subscribe with ffplay, it does not work, the output looks like this :
    2018/01/01 20:57:25:618 [web]     nan    :  0.000 fd=   0 aq=    0KB vq=    0KB sq=    0B f=0/0

    When I subscribe again (while the previous process is still ongoing), it works : 2018/01/01 20:57:25:828 [web]  340.93 M-V:  0.001 fd=   0 aq=    0KB vq=  131KB sq=    0B f=0/0

    The only difference in output to the command line is this :

    Input #0, live_flv, from 'rtmp:{stream-url-here}':=0/0  
    2018/01/01 20:57:15:427 [web]   Metadata:

    Baseline), yuv420p(progressive), 1024x640, 20 fps, 20 tbr, 1k tbn, 40
    tbc

    I am trying to figure out why it only works on the second time subscribing, and this is the difference, which I assumes signals the it successfully received the streams info, but I am trying to figure out why it only works the second time.

    Thanks !!

  • ffmpeg cannot generate thumbnail

    8 mai 2018, par rabbit

    In Windows to make a thumbnail with ffmpeg I use :

    ./ffmpeg -i 1.mp4 -ss 00:00:01 -f image2 1.jpg

    or :

    ./ffmpeg -ss 00:00:01 -i 1.mp4 -f image2 1.jpg

    But none can generate a thumbnail, it displays :

  • Evolution #3692 : Suivre les évolution de MediaJS

    28 juin 2017, par Franck D

    Hello, juste pour dire que la version 4.2.2 vient de sortir https://github.com/mediaelement/mediaelement/blob/master/changelog.md
    J’ai pas fait de test, Il y a pas mal de corrections de bugs, mais aussi la mise à jour de l’API Facebook. Elle était en 2.6 et passe en 2.9 !
    https://github.com/mediaelement/mediaelement/commit/8a5760dc6ca3fe5c32eb26f44142e579d718128a
    L’intérêt de mettre à jour la lib, c’est que cela fonctionne, après le 13 juillet 2018 https://developers.facebook.com/docs/apps/changelog

    Nous ne mettons pas souvent à jour les libs, (sauf sécu ou gros bug) dans les versions mineures de spip, et nous ne sortons pas souvent de mise à jour "majeure" (avec un peu de chances, la 3.3 sortira d’ici juillet 2019), c’est pour cela que je pense que cela serait une bonne idée de mettre la nouvelle lib, car sinon, une fonction ne fonctionnera plus dès l’année prochaine :-(
