  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • Unable to compile ffmpeg to support NVIDIA hardware acceleration

    17 mars 2017, par user3847630

    I am trying to compile ffmpeg to support NVIDIA hardware acceleration. But I am getting the following errors :

    libavcodec/cuvid.c: In function ‘check_cu’:
    
libavcodec/cuvid.c:83:5: error: implicit declaration of function ‘cuGetErrorName’ [-Werror=implicit-function-declaration]
    
     cuGetErrorName(err, &err_name);
    
     ^
    
libavcodec/cuvid.c:84:5: error: implicit declaration of function ‘cuGetErrorString’ [-Werror=implicit-function-declaration]
    
     cuGetErrorString(err, &err_string);

    I have installed CUDA by following the instruction on NVIDIA Developer forum. The configuration I used is :

    ./configure --enable-nonfree --enable-nvenc --enable-cuda --enable-cuvid --enable-libx264 --enable-gpl

    The GPU on my laptop is NVIDIA Corporation GM108M [GeForce 840M].

  • Ffmpeg hardware acceleration unsupported formats betwen transpose and auto_scaler_0

    11 août 2021, par Eduard6421

    I am trying to develop a transoding service which makes use of nvidia hardware acceleration capabilities ( The gpu used in this process is a Tesla T4) ; I want to generate a mpeg-dash playlist for my video so that i can stream it ;

    


    ffmpeg -y -hwaccel cuda -hwaccel_output_format cuda -i mobil1.mp4 -c:v h264_nvenc -c:a aac  \
-map v:0 -b:v:0 1000k -maxrate:0 1500k -bufsize:0 2500k -filter:v:0 "scale_npp=1920:1080:force_original_aspect_ratio=decrease" -map 0:a -b:a 128k \
-f dash dash.mpd


    


    But when mobile videos are uploaded ( which have rotation metadata ) I encounter the following error :

    


    Impossible to convert between the formats supported by the filter 'transpose' 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 #0:0


    


    How can i solve this issue ? I am using the following docker image :
jrottenberg/ffmpeg:4.4-nvidia
