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 (Input 8K AAC -> (AAC FLV) youtube streaming noise
17 septembre 2017, par Biswa DasHello I run a streaming encoder for a non profit cause. Chosen FFMPEG as it’s very simple and doing the job near perfectly however the audio is noisy popping and cracking. Video is crystal clear.
ffmpeg version N-86950-g1bef008 Copyright (c) 2000-2017 the FFmpeg developers
built with gcc 7.1.0 (GCC)Here is my command.
ffmpeg -rtsp_transport tcp -i $RTSP_SRC -vcodec copy -af "volume=12dB" -ar 8000 -acodec aac -f flv rtmp://a.rtmp.youtube.com/live2/$DEST_KEY
However when I just play the stream the noise levels are quite acceptable.
ffplay -rtsp_transport tcp -i $RTSP_SRC
What I have tried so far.
- Change input audio sampling from 8K to 16K (that’s all is supported currently). It made the noise problem much worse. I can’t change it to a native FLV sampling(44100 or 22050 or 11025) at least not yet, the integrated rtsp stream does not support it.)
- My working theory is during resampling stream noise is getting boosted. So to eliminate that I tried audio copy codec even then there is no significant improvement.

FFMPEG : Encoding settings to meet YouTube recommendation.
1er novembre 2016, par Dinindu PereraSo I need to encode to meet these guidelines from YouTube for 480p and 1080p videos. I need help in the settings of FFMPEG. The video should encode reasonably fast.
These are the guidelines :
480p 30fps x264- Video Bitrate : 2560 kbps
- Audio Bitrate : 384 kbps
1080p 30fps x264
- Video Bitrate : 8192 kbps
- Audio Bitrate : 384 kbps
I’m still learning the ropes with video encoding. Thanks in advance :)
