Creating farms of unique websites
13 avril 2011, parMediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...) -

FFmpeg - how to configure H264 encoder to output 1 packet after 1 frame (no B frames)
30 octobre 2018, par maxestIs it possible to configure FFmpeg encoder such that when I call :
avcodec_send_frame
I can then call :
avcodec_receive_packet
and receive the packet ?
Right now I have to call avcodec_send_frame a few dozens times before avcodec_receive_packet returns any valid packet. In other words I would like the latency to be reduced to 0.

FFMPEG : How to chose a stream from all stream
3 mars 2016, par combo_ciI try to convert a UDP stream (that genrated from DVB signal) to HLS m3u8 file with this code :
ffmpeg -i udp://239.1.2.1:60001 -acodec aac -strict -2 -vcodec libx264 -hls_wrap 100 -f hls /var/www/html/ts/1.m3u8UDP stream contain 1 channel (in this case IRIB-TV1).
When i run this code ffmpeg detect all of service and channel that streamed from DVB card with this message :
Input #0, mpegts, from 'udp://239.1.2.1:60001':

service_provider: IRIBAs you see ffmpeg finf 4 channel in UDP stream, But VLC play only channel 1(IRIB-TV1).
Now i have have 2 question :
1-Can I get all channel and service via this ffmpeg code ?
2-Can i choose a spesial stream from this ffmpeg code ?(i know that ffmpeg can choose a stream with -map otion but i want to choose other service_name that in output log)
output file is :

FFMPEG : How to chose a stream from all stream
17 janvier 2020, par AliI try to convert a UDP stream (that genrated from DVB signal) to HLS m3u8 file with this code :
ffmpeg -i udp://239.1.2.1:60001 -acodec aac -strict -2 -vcodec libx264 -hls_wrap 100 -f hls /var/www/html/ts/1.m3u8UDP stream contain 1 channel (in this case IRIB-TV1).
When I run this above code, ffmpeg detect all of service and channel that streamed from DVB card with this message :
Input #0, mpegts, from 'udp://239.1.2.1:60001':

service_provider: IRIBAs you see ffmpeg finf 4 channel in UDP stream, But VLC play only channel 1(IRIB-TV1).
Now I have have 2 question :
1-Can I get all channel and service via this ffmpeg code ?
2-Can I choose a special stream from this ffmpeg code ?(I know that ffmpeg can choose a stream with -map option but I want to choose other service_name that in output log)
output file is :
