Emballe médias : à quoi cela sert ?
4 février 2011, parCe plugin vise à gérer des sites de mise en ligne de documents de tous types.
Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ; -
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.

Raspberry Pi 4 live streaming with ffmpeg [closed]
12 décembre 2019, par BerriSo speedify created a blog post and youtube video about making an IRL streaming backpack using the Elgato Cam Link 4k, Raspberry Pi 4, and ffmpeg.
They gave pretty detailed instructions, and included downloads to prebuilt scripts/commands to get it all running once put together.
Blog post :
https://speedify.com/blog/how-to/build-irl-streaming-backpack-complete-guide/ffmpeg command from post :
ffmpeg_command = “/home/pi/bin/ffmpeg -nostdin -re -f v4l2 -s ‘1280×720’ -framerate 24 -i /dev/video0 -f alsa -ac 2 -i hw:CARD=Link,DEV=0 -vcodec libx264 -framerate 24 -rtbufsize 1500k -s 1280×720 -preset ultrafast -pix_fmt yuv420p -crf 17 -force_key_frames ‘expr:gte(t,n_forced*2)’ -minrate 850k -maxrate 1000k -b:v 1000k -bufsize 1000k -acodec libmp3lame -rtbufsize 1500k -b 96k -ar 44100 -f flv – | ffmpeg -f flv -i – -c copy -f flv -drop_pkts_on_overflow 1 -attempt_recovery 1 -recovery_wait_time 1 rtmp://live.twitch.tv/app/live_” + streamKey + “‘\n”I replaced
-i hw:card=link,dev=0in that command with-i hw:2,0because-i hw:card=link,dev=0gave me "file does not exist" errors in the log. "streamkey" is filled with the appropriate key for my twitch.Github Resources + Instructions used :
https://github.com/speedify/rpi-streaming-experimentI’m using all the exact same hardware as outlined in the post, and have gotten everything installed correctly as far as I can tell.
But when I go to run the ffmpeg command, it seems like nothing actually gets sent over to twitch correctly.The log after trying to run it looks like this.
If anybody has any insight as to what may be going wrong, it would be greatly appreciated.Starting ffmpeg

Converting mkv to mp4 with ffmpeg sometimes loses video
9 décembre 2019, par RobertWHow can I create a universal as possible command line to convert mkv to mp4 ?
I fixed an issue where sometimes I’d lose audio (I think) and now I’m losing video.
This is the command I currently use (I’ve used a few, including-analyzeduration 1G -probesize 50Mbut I always end up with broken videos at some point) :if [[ $(pgrep -i ffmpeg) ]] ; then
echo "FFMPEG IS ALREADY RUNNING!"
else
echo "Starting mkv to mp4 conversion...";
for i in /var/www/html/uploads/Videos/*/*/*/*.mkv;
do name=$(echo "${i//.mkv/}");
echo "$name";
ffmpeg -n -i "$i" -c copy -c:a aac -movflags +faststart "${name}.mp4"; rm -v -f "${name}.mkv";
done
fiOutput of running that on the specific videos I’m losing picture on :

FFmpeg recording works on one laptop but not the other
30 novembre 2019, par Jason TThe following command :
ffmpeg -f dshow -framerate 30 -video_size 640x480 -i video="HD Pro Webcam C920" out.mp4works on one laptop (with C920 LogiTech camera) (Im calling it GOOD LAPTOP). It outputs a recorded video. But it will fail on another laptop (called BAD LAPTOP) and by fail on another I mean - it doesnt output a video (see below for output).
The suggestions are to change parameters based on the specific error that occur on BAD LAPTOP. I have tried many different suggestions but they dont seem to work. Furthermore, they dont provide much insight into the underlying cause of the problem.
Ive used the same camera on both laptops. Im using static windows binaries downloaded from FFmpeg web-site (veranoe). Please note the versions used below were different but that doesnt appear to matter.
Trying to diagnose. Anyone have an idea of where the problem may lie. It seems to indicate a problem at the level of the system / camera setup.
Please note that I’ve updated BAD LAPTOP but still no dice. Also please note that Ive tried this on several systems already and it seems to run ok (i.e., produce an output video)
BAD LAPTOP :
$ ffmpeg -y -f dshow -framerate 30 -video_size 640x480 -t 10 -i video="HD Pro Webcam C920" out.mp4
