MediaSPIP version 0.1 Beta
16 avril 2011, parMediaSPIP 0.1 beta est la première version de MediaSPIP décrétée comme "utilisable".
Le fichier zip ici présent contient uniquement les sources de MediaSPIP en version standalone.
Pour avoir une installation fonctionnelle, il est nécessaire d’installer manuellement l’ensemble des dépendances logicielles sur le serveur.

Lost in converting hardware accelarated ffmpeg decoder to raw loopback device
5 septembre 2019, par MikeynlBefore reaching out, i googled enough, tried many different docker containers, building, compiling etc etc.
What I am looking for is a hardware accelerated conversion from a rtsp stream to a /dev/video0 device. I have a working v4l2loopback kernel module, and the following command is working :
ffmpeg -loglevel panic -hide_banner -i "rtsp://192.168.0.17/user=admin&password=&channel=1&stream=0.dsp?real_stream" -f v4l2 -pix_fmt yuv420p /dev/video0I can test the /dev/video0 device to take a screenshot :
ffmpeg -f video4linux2 -i /dev/video0 -ss 0:0:2 -frames 1 /var/www/html/out.pngAbove is working, but taking around 30 / 50% cpu usage to decode/encoding.
I have a fully working test environment with a GeForce GTX 1050. All cuda / nvidia related drivers are in place. ffmpeg is compiled with the following options :
configuration: --enable-nonfree --disable-shared --enable-nvenc --enable-cuda --enable-cuvid --enable-libnpp --extra-cflags=-I/usr/local/cuda/include --extra-cflags=-I/usr/local/include --extra-ldflags=-L/usr/local/cuda/lib64My last attempt was :
ffmpeg -hwaccel cuvid -c:v h264_cuvid -i "rtsp://192.168.0.17/user=admin&password=&channel=1&stream=0.dsp?real_stream" -c:v rawvideo -pix_fmt yuv420p -f v4l2 /dev/video0It gives me an error :
Impossible to convert between the formats supported by the filter ’Parsed_null_0’ and the filter ’auto_scaler_0’
Error reinitializing filters !
Failed to inject frame into filter network : Function not implemented
Error while processing the decoded data for stream #0:0I have at the moment absolute no idea anymore how to solve this.
Thanks in advance !

The final lib was created successfully, no error message in log file,
but when I import the lib to my Xcode Project,
the linker give me tons of errors(missing symbols like :
Undefined symbol: _pjsua_vid_codec_set_priority).
I found thepjsua_vid.ois very small(200Bytes) compare to my pjsip+openh264 build file(was 47KB), perhaps this is the reason cause the link error.
