Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang 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. -

Youtube stream of looping JPG stops randomly
6 juillet 2021, par timw99Hi I'm fairly new at ffmpeg.


I'm currently trying to get a low FPS Youtube stream working over RTMP using a JPG on loop which content gets changed using a NodeJS script periodically. I'm using the following command to stream (variable 3 is my stream key) :


ffmpeg -re -loop 1 -pix_fmt bgr24 -framerate 5 -i img/now.jpg -re -stream_loop -1 -i output.mp3 -f flv -vcodec libx264 -profile:v main -g 60 -keyint_min 30 -b:v 400k -minrate 400k -maxrate 400k -preset ultrafast -tune zerolatency -bufsize 2000k rtmp://a.rtmp.youtube.com/live2/$3



There's multiple things wrong here. The bitrate doesn't actually stay at 400k/s. It just goes to around 200-1000k and then just starts decreasing until the stream stops (usually at around 200-300k bitrate). It still seems like data is being sent (bitrate and current FPS are still updated (though they're very low) and speed goes parabolic. The frame counter itself just stops and Youtube doesn't continue streaming. See example :


frame= 515 fps=5.0 q=12.0 size= 5803kB time=00:01:42.84 bitrate= 462.3kbits/
frame= 518 fps=5.0 q=11.0 size= 5824kB time=00:01:43.41 bitrate= 461.3kbits/

I'm using a Digital Ocean VPS to run it, but the same happens on my own desktop which definitely has the hardware for a simple stream like this. Could it have something to do with me replacing the JPG content while trying to stream it ? I get this error every once in a while, but it seems like it fixes itself judging by the info :


[mjpeg @ 0x562824d1fb40] overread 8
[mjpeg @ 0x562824d1fb40] EOI missing, emulating



I can provide more information if it's needed. Thanks in advance.

Piping to ffmpeg on windows
8 septembre 2021, par Totte KarlssonI'm planning to pipe live image data (bitmaps) to ffmpeg in order to create an AVI file.



Looking at the ffmpeg docs regarding pipes, https://ffmpeg.org/ffmpeg-protocols.html#pipe, it only mentions UNIX pipes.



I'm planning using the technique described here : is it possible to send ffmpeg images by using pipe ?



Is there a major difference on Windows that causes piping data to ffmpeg not working on Windows ?

uwp app throw error when install from package but works fine in any mode when run directly launching from visual studio
30 septembre 2020, par Abhishek SharmaI have created an app wrapping FFmpeg in uwp now for the requirement
I have all the major dll of FFmpeg and then set to content and copy always in property
now when I launch the app installed from the visual studio in any mode weather release, debug, x86,x64 it works fine but as I created a package and then install the app and run it, it throws an error where it says that dll not found not directly but says file not found which is because of dll because I face that problem in debug mode before and it's because of dll not available to uwp
you can look at the project here : https://github.com/AbhiSharma9350/Winfftool
