  • Encoding and processing into web-friendly formats

    13 avril 2011, par

    MediaSPIP automatically converts uploaded files to internet-compatible formats.
    Video files are encoded in MP4, Ogv and WebM (supported by HTML5) and MP4 (supported by Flash).
    Audio files are encoded in MP3 and Ogg (supported by HTML5) and MP3 (supported by Flash).
    Where possible, text is analyzed in order to retrieve the data needed for search engine detection, and then exported as a series of image files.

  • Encoding 25mp video

    18 août 2016, par Yuval.Sightec

    I have a 25MP uncompressed video file of 100 frames.

    I tried to encode it with ffmpeg and h264 encoder into a .mp4 file, but the encoding got stuck around the 10th frame.
    This is the script :

    avconv -y -i input.avi -c:v libx264 -preset medium -b:v 5000K -pass 1 -c:a libfdk_aac -b:a 5000K -f mp4 /dev/null && \
    
avconv -i input.avi -c:v libx264 -preset medium -b:v 5000K -pass 2 -c:a libfdk_aac -b:a 5000K output.mp4

    I am running it on a jetson TK1 with nvidia gpu, is there any way to use an accelarating encoding in order to make the encoding possible ?

    Please, if you can, give me a sampler script of something that might work.
    Right now, I dont care how much time the encoding take, as long as it will work.

    Thank you in advance ! :)

  • avcodec/nvenc : include nvEncodeAPI v7 SDK header

    avcodec/nvenc : include nvEncodeAPI v7 SDK header

    As Nvidia has put the most recent Video Codec SDK behind a double
    
registration wall, of which one needs manual approval of a lenghty
    
application, bundling this header saves everyone trying to use NVENC
    
from that headache.
    

    The header is still MIT licensed and thus fine to bundle with ffmpeg.
    

    Not bundling this header would get ffmpeg stuck at SDK v6, which is
    
still freely available, holding back future development of the NVENC
    
encoder.

  • Intel QuickSync and Nvenc at same Time on Ubuntu Server

    15 mai 2019, par Ahmet Gürer

    Im setting up a new Ubuntu Server with an Intel i7 6700k and Nvidia Gpu 1080ti. Is it possible to use Intel iGPU and Nvidia Gpu at same time on transcoding ?

    Example :
    Stream 1 transcoding with iGPU
    Stream 2 transcoding with nvenc

    I will use it at same time. Is that possible ?

    • I Installed Nvidia Cuda Drivers and Intel SDK
    • Activated iGPU and Nvidia GPU
    • Try to start with iGPU but get the error that Driver not found
