  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • Unable to playback hardware encoded H.264 to RED5 server using FFmpeg

    26 février 2019, par Les

    I have a USB camera that is capable of H.264 on-board compression. I use the following FFmpeg command line to grab the encoded H.264 from the camera and put it in a ’flv’ container :

    ffmpeg -y -f dshow -vcodec h264 -i video="USB Camera" -vcodec copy -copyinkf -f flv c:\temp\test.flv

    This works as expected and I can view the video using VLC no problem. Following this principle I then attempt to stream to a RED5 server using the following command :

    ffmpeg -y -f dshow -vcodec h264 -i video="USB Camera" -vcodec copy -copyinkf -f flv rtmp://192.168.75.34/live/livestream

    The RED5 server detects the stream but I am unable to connect to it and view it using my basic Python program.

    If I do the same thing but use FFmpeg to carry out H.264 encoding of the default capture pin (MJPEG), it will stream correctly.

    I’m not sure if there is some flag in the command line that I might be missing ? Any help with this issue would be much appreciated.

    Here is the log output from the second FFmpeg command :

    C :\ffmpeg-latest-20190219\ffmpeg-static\bin>ffmpeg -y -f dshow -vcodec h264 -i video="USB Camera" -vcodec copy -copyinkf -f flv rtmp ://192.168.75.176/live/livestream"

  • Why is the filesize different when swapping audio tracks using ffmeg ?

    20 août 2021, par Brian

    I have a movie that I have encoded using Handbrake on a Mac a long time ago. When I encoded the movie, I put the stereo audio as track 1 and the 5.1 audio as track 2. The starting filesize is 853,320,914 bytes. Below is the data from ffprobe.

Unsupported codec with id 100359 for input stream 3


    


    My goal is to swap the stereo audio track with the 5.1 audio track and make the 5.1 audio track the default without having to reencode. To do this, I used the following command :

    


    ffmpeg -i "Annabelle - Comes Home (2019)/Annabelle - Comes Home (2019)_old.m4v" -map 0:v:0 -map 0:a:1 -map 0:a:0 -disposition:a:0 default -disposition:a:1 none -c copy "Annabelle - Comes Home (2019)/Annabelle - Comes Home (2019).m4v"

    


    Everything works as it should, I think anyways as I didn't get any errors...

    What I don't understand is why is the file size different ? The resulting file is larger at 854,292,790 bytes. Shouldn't the file sizes be the same since I literally just swapped tracks 0 and 1 ?

    Il reste des gifs pas très jojo sur le plugin.
    À remplacer par https://www.florin-pop.com/blog/2019/03/css-pulse-effect/ par exemple.
