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. -

FFMpeg Combine wav and avi to mp4
15 avril 2016, par krisphI am trying to combine a wav file and a avi in to a single mp4.
I can do this with the following via php :
$command = 'start /B convertvid\bin\ffmpeg -nostdin -i Temp\\temp.avi -i Temp\\temp.wav -y -filter:v scale=1920:-1 -c:v libx264 -preset ultrafast -movflags faststart -crf 31 -c:a libvo_aacenc -b:a 64k Temp\\output.mp4';
However it takes an age to complete and i need to speed it up, i was just wondering is there anything that could be done to optimize the commands to make it faster ?
I have tried the command using just the command line and it still takes ages...
C:\inetpub\wwwroot\Update\>convertvid\bin\ffmpeg -i Temp\temp.
avi -i Temp\temp.wav -y -c:v libx264 -preset ultrafast -movflags faststart -crf
31 -c:a libvo_aacenc -b:a 64k Temp\testhis.mp4

Encode videos to send with WhatsApp
28 avril 2017, par piegamesI have a series of PNG images of a video I rendered and now I want so send it via WhatsApp. I used to encode my videos with the command from this answer, but apparently the videos can only be played from WhatsApp web ; on the phone I still get an error message. How do I convert them so that they can also be played on phone ?

Problem recording camera stream through ffmpeg - Inappropriate ioctl for device
16 septembre 2021, par Otter_warriorI'm trying to record a camera stream through ffmpeg, but I'm struggling to understand how to write a correct recording command.


This is the camera format according to v4l2


$ v4l2-ctl -d 1 --list-formats-ext
ioctl: VIDIOC_ENUM_FMT
 Index : 0
 Type : Video Capture
 Pixel Format: 'RG12'
 Name : 12-bit Bayer RGRG/GBGB
 Size: Discrete 1920x1080
 Interval: Discrete 0.033s (30.000 fps)



And this is what I tried so far


ffmpeg -framerate 30 -video_size 1920x1080 -i /dev/video0 output.mkv



which would return this and an empty output file


$ ffmpeg -f v4l2 -framerate 30 -video_size 1920x1080 -i /dev/video0 output.mkv

I'm new to ffmpeg so I can't determine which settings or properties could help me with this format, or if this format is even supported at all. Any help would be greatly appreciated.


Note : I am working on a Jetson board, but gstreamer or nvgstcapture are not an option
