  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

    hwcontext_vulkan : do not use optical flow queueus by default

    We don't use them, and on NVIDIA, each queue takes around 30ms
    
to allocate, and the driver has a global limit of ONLY 112 queues.

    15 novembre 2017, par Red5goahead

    Is it possible that with Nvidia whql driver (385.69) for Windows 10 x64 1709 Cuda is not working to deinterlace H264 video stream ?

    Mpc-HC, lav codec screenshot setup
    enter image description here

    Please refer to this one minute sample /111 MB

    I tried with MPC-HC and FFMPEG h264_cuvid decoder with -hwaccels and -deint switch (-resize it’s working fine for example), no other sw filter in the chain of course, the result color space is Cuda/NV12

  • How to record video from old webcam using ffmpeg on Linux ?

    5 février 2015, par Moomin

    After couple of hours I finally accepted my absolute lack of knowledge and decided to post this question here.
    I’m trying to record video from an old external USB webcam (Media-Tech MT400 -> 0c45:6029) with ffmpeg but without much success.

    First thing I’ve tried was to run to try something that works for the built-in webcam) :

    ffmpeg -f v4l2 -i /dev/video1 test.avi

    But that returned a following error :

    Cannot find a proper format for codec 'none' (id 0), pixel format 'none' (id -1)

    Here is what I get from v4l2-ctl -d /dev/video1/ --all --list-formats-ext

    Unfortunately that was not of much help to me, but I tried capturing webcam output with VLC and recording it which.... WORKED !

    I tried ffmpeg -i vlc-record[...].avi on VLC recording which returned following information :

    Input #0, avi, from 'vlc-record-2015-02-05-05h22m52s-v4l2____dev_video1-.avi':
    
  Duration: 00:00:01.58, start: 0.000000, bitrate: 26937 kb/s
    
    Stream #0:0: Video: rawvideo (I420 / 0x30323449), yuv420p, 352x288, 27671 kb/s, 22.10 tbr, 22.10 tbn, 22.10 tbc

    I thought that was enough information (rawvideo and yuv420p) led to run ffmpeg with following arguments (I have found yuv4 using ffmpeg -formats)

    ffmpeg -f rawvideo -vcodec yuv4 -i /dev/video1 test.avi

    The result was only slightly better than one that I saw after my first attempt :

    [IMGUTILS @ 0x7fff497d3920] Picture size 0x0 is invalid
    
[rawvideo @ 0x9c4720] Could not find codec parameters for stream 0 (Video: yuv4, yuv420p, -4 kb/s): unspecified size
    
Consider increasing the value for the 'analyzeduration' and 'probesize' options
    
/dev/video1: could not find codec parameters

    Again after some searching and several tries I added ’-video_size cif` option and.... it WORKED !!!!

    Well, not really...

    Input #0, rawvideo, from '/dev/video1':
    
  Duration: N/A, start: 0.000000, bitrate: 30412 kb/s

    LED on webcam turned on as during capturing video with VLC but all that was recorded was TV-like noise.

    So here I am after 7 hours - still without work solution - asking for your help.

    Thanks in advance.
