  • FFMPEG- Streaming Stops after few seconds

    25 mars 2019, par Manjot Singh Kalsi

    Hi there dear community

    This is the thing that I am dealing with, since last few days. After thorough search in the ffmpeg community, I was unable to find the solution. I am unable to Stream local flv, to facebook rtmp server.

    I am running the following command to stream my local flv video to the rtmp server of Facebook for Live-Streaming of my local File.

    ```ffmpeg -re -i SampleM.flv -acodec libmp3lame  -ar 44100 -b:a 128k -pix_fmt yuv420p -profile:v baseline -s 426x240 -bufsize 6000k -vb 400k -maxrate 1500k -deinterlace -vcodec libx264 -preset veryfast -g 30 -r 30 -f flv "rtmp://live-api.facebook.com:80/rtmp/my_key"```

    It has been a misfortune-situation that even after reading ffmpeg documentation, I have been unable to find the issue that is leading me to this situation as follows.

    I am still missing something that i need to know.

    Following is the log to the execution of the above command.

    This Image shows that The stream was alive few Few Seconds on Facebook

[flv @ 0000020c0bc97fc0] Failed to update header with correct filesize.```

    Please correct me, the above error listed in the log, seems to be the main cause that the video stops streaming after few seconds. I’ve checked for the latency issues, But they won’t help anyway.

    Please Help me to tackle this issue. I’ll be very much thankful. :’)

    Streaming ends even earlier, when I use Google compute engine, instead my own PC as streaming service.

  • Anomalie #4324 (Fermé) : La vignette d’une video ne sert pas comme logo d’un article

    26 avril 2019, par Franck D

    Hello :-)
    SPIP 3.2.4 [24285]
    Avec uniquement les plug « meta+ » version 2.2.3 et « oembed » en version 2.0.10
    php 5.6.40

    Il semble y avoir un bug avec les vignettes des vidéos, https://contrib.spip.net/Metas-version-2#comment500975
    J’ai fait d’autres tests, et en faite le problème est présent même avec une vidéo qui est hébergé localement et avec l’ajout manuellement d’une vignette via la médiathèque
    Je pense que c’est un bug, car, il y a une différence de comportement entre une image, et une vignette qui sert pour une vidéo

    De même, si dans un article, je ne mets pas mais et que j’ajoute une vignette à ce document, alors cela fonctionne, Facebook voit bien l’image qui sert pour la vidéo
    Franck
