  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP 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" (...)

  • Does ffmpeg support 7.x channels encoding in Dolby Digital format (.ac3) ?

    4 novembre 2019, par CC2023

    Using ffmpeg, I was able to encode 5.x channels from .wav to .ac3. But 7.x channels did not work. The encoded .ac3 missed channel 6th and 7th.

    Does ffmpeg support 7.x channel encoding for .ac3 ?

    My ffmpeg version git-2019-10-28-68f623d. Thanks.

  • ffmpeg hwmap SW decoded frame to OpenCL and hwmap back to h264 for SW encode

    3 novembre 2019, par Oleksandr Kyrpa

    I trying speed up process and avoid copy frames between GPU and CPU. But got error : "Segmentation fault : 11", so may be I’m doing something wrong ?

    My full ffmpeg command and log here :

    ./ffmpeg -i ../720.mp4 -init_hw_device opencl=ocl:0.1 -filter_hw_device ocl  -filter_complex "hwmap,avgblur_opencl=30,hwmap"  -c:v h264 -an -t 10 -y ../out_blur.mp4 -loglevel debug

    Output :

  • FFMPEG NVENC HEVC to H264

    18 octobre 2022, par Sambir

    I try to transcode a HEVC 4k broadcast down to 1080p H264. HEVC 4K to HEVC 1080p works but when I try hevc to h264 i get "No NVENC capable devices found"

    



    Now I am wondering is it not possible to fully hw transcode HEVC to H264 ?

    



    Code used :

    



    ffmpeg -timeout 10000000 -reconnect 1 -reconnect_at_eof 1 -reconnect_streamed 1 -reconnect_delay_max 2 -hwaccel_device 0 -hwaccel cuvid -vcodec hevc_cuvid -resize 1920x1080 -i 'http://inputstream' -max_muxing_queue_size 1024 -map 0:0 -map 0:2 -acodec libfdk_aac -b:a 96k -c:v h264_nvenc -gpu 0 -preset llhq -profile high -rc:v vbr -qmin:v 26 -qmax:v 32 -b:v 4M -maxrate 4M -bufsize 8M -threads 0 -r 25 -g 100 -f mpegts 'udp://127.0.0.1:6472' 


    



    When I run the code :

    



    [h264_nvenc @ 0x3bf42c0] Provided device doesn't support required NVENC features
Error initializing output stream 0:0 — Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
Conversion failed !

    



    Is it not possible to convert HEVC back to H264 ?

    



    log :
