    Modules spécifiques
    Pour la configuration d’Apache, il est conseillé d’activer certains modules non spécifiques à MediaSPIP, mais permettant d’améliorer les performances : mod_deflate et mod_headers pour compresser automatiquement via Apache les pages. Cf ce tutoriel ; mode_expires pour gérer correctement l’expiration des hits. Cf ce tutoriel ;
    Il est également conseillé d’ajouter la prise en charge par apache du mime-type pour les fichiers WebM comme indiqué dans ce tutoriel.

  • Convert input gray16le to RGB output stream

    22 novembre 2018, par Albert Garcia

    I’m reading a v4l2 format input video with pixel format gray16le from a USB camera connected to my computer. I can display it without problems.

    My question is that I want to read that video with ffmpeg (on /dev/video0) and stream it to a websocket. If I read a "normal" rgb video, this is the command that I’m using to accomplish it :

    ffmpeg -f v4l2 -i /dev/video0 -framerate 9 -c:v mpeg1video -f mpegts https://......

    When I try to read from the gray16le format camera, I’ve tried lots of commands but the output is always in grayscale. For example :

    ffmpeg -f v4l2 -i /dev/video0 -framerate 9 -pix_fmt yuyv422 -c:v mpeg1video -f mpegts https://......
    
ffmpeg -f v4l2 -i /dev/video0 -framerate 9 -pix_fmt rgb24 -c:v mpeg1video -f mpegts https://......

    Is there an option in ffmpeg to apply a colormap or a LUT to the input video before streaming it ?

    Thanks !

  • Unable to build ; undefined symbols for architecture x86_64 :

    In the process of trying to create an RTSP screen streaming server, I tried looking at CocoaSplit for an example.

    



    Problem is, I can't get it to compile.

    



    I have FFMpeg installed on my computer using Homebrew following FFMpeg's guide on https://trac.ffmpeg.org/wiki/CompilationGuide/MacOSX .

    



    But on compilation, Xcode is throwing out errors such as

    



    Undefined symbols for architecture x86_64:

"_cmnMemAlloc", referenced from:_aac_encode_init in libavcodec.a(libvo-aacenc.o)
"_cmnMemCheck", referenced from:_aac_encode_init in libavcodec.a(libvo-aacenc.o)
"_cmnMemCopy", referenced from:_aac_encode_init in libavcodec.a(libvo-aacenc.o)
"_cmnMemFree", referenced from:_aac_encode_init in libavcodec.a(libvo-aacenc.o)
"_cmnMemSet", referenced from:_aac_encode_init in libavcodec.a(libvo-aacenc.o)


    



    and so on.

    



    The header search paths field in project settings has the directory of /usr/local/include in it.

    



    What seems to be the problem here ?
