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. -

nginx : [emerg] invalid port in url "http://192.168.0.100:80/live" in nginx.conf - Restreaming OBS to LAN
17 novembre 2018, par popek069I want to restream OBS to LAN. So I set up nginx server. The server receive stream from OBS using RTMP and restreams it to HTTP to view from another device.
Streaming from OBS works, but when I start nginx I get an errorPS C:\Users\popek\Downloads\nginx> .\nginx.exe -s reload
nginx: [emerg] invalid port in url "http://192.168.0.100:80/live" in C:\Users\popek\Downloads\nginx/conf/nginx.conf:187I’m new to nginx and I’m running Windows 10, nginx server and OBS are on the same pc with ip 192.168.0.100
I’d like to also reencode stream using ffmpeg if it’s possible. I know ffmpeg, I don’t know only how to set input and output.Config : (nginx.conf)

how to not remove transparency using negate option on png files ffmpeg
27 mars 2024, par ReilbasI'm new to FFMPEG.
To make it simple, I've created a program that applies a negative filter to small images in png format. For some of the images, everything is fine and the transparency is maintained... But for others, FFMPEG converted the transparency to either black or white pixels.


I'm just using the command :

ffmpeg -y -i input.png -vf negate output.png


I downloaded the latest binaries for windows from https://www.gyan.dev/ffmpeg/builds/ (2024/03/25)

Should H.264 bit rate be multiples of 8 ?
31 août 2016, par Dan SharpI’m working on a video platform receiving H.264 video and building an HLS stream (transmuxing the H.264 to Mpeg2 TS segments via calls to ffmpeg).
I wanted to set the bit rate to be about 2000 kbps, but I’m wondering : does it matter if it’s 2000 or 2048 ?
In other words, do things calculate better if the bit rate is multiples of 8, like 512 or 2024 or 2048 ?
I don’t know enough about how the bit rate is used, either on the sending side (camera) or on the processing side (ffmpeg).
From tests... I can’t see any noticeable difference between 2000 and 2048, but maybe one is slightly better than another for the transmuxing and segmenting ?
I welcome any thoughts/advice.
