  • Demande de création d’un canal

    12 mars 2010, par

    En fonction de la configuration de la plateforme, l’utilisateur peu avoir à sa disposition deux méthodes différentes de demande de création de canal. La première est au moment de son inscription, la seconde, après son inscription en remplissant un formulaire de demande.
    Les deux manières demandent les mêmes choses fonctionnent à peu près de la même manière, le futur utilisateur doit remplir une série de champ de formulaire permettant tout d’abord aux administrateurs d’avoir des informations quant à (...)

  • Creating an infinite MP4 with FFMPEG (not looping)

    28 décembre 2017, par ESala

    I know that mp4 streaming is a no-no, this project is just for playing with video :)

    I have an infinite h264 stream provided by a Raspberry Pi camera, and I want to wrap it in an infinite mp4 so I can watch it in a browser.

    (source) raspivid -t 0 -w 1640 -h 1232 -fps 20 -b 500000 -vf -hf -o -

    (ffmpeg) ffmpeg -r 20 -i - -vcodec copy -movflags "frag_keyframe+empty_moov" -f mp4 pipe:1

    What I do is that I pipe (source) into (ffmpeg) and then (ffmpeg) to my program which buffers, uploads to a server, authenticates, etc.

    This works fine, and I am able to watch the stream from a browser.

    PROBLEM : the problem is that (ffmpeg) stops outputting data after 6 minutes.

    When the video reaches 6:00, the (ffmpeg) command just stops writing data to itsstdout.

    I tried changing the framerate, bitrate, resolution, etc but nothing makes a difference, it always stops at 6:00.

    I checked the (source) command and it is still writing to its own stdout.

    QUESTION : Is there something that I am missing ? why does it stop writing to stdout after just 6 minutes ? is the command missing some flag to allow an infinite mp4 ?

    EDIT : added the output of -report below.

  • ffmpeg trying to remove the first few seconds of video

    4 janvier 2018, par zeroasterisk

    I’m trying to remove a few seconds off the front of a video stream (audio already excluded), and I’m getting strange results : I would think that for every second I increase -ss by, the resulting file would be a second shorter... that doesn’t seem to be the case.

    original     ==> 01:04:52.84
    
-ss 19       ==> 01:04:42.84 (diff = 10) [command history shown below]

    Command : ffmpeg -ss # -i temp.mp4 -y -vcodec copy  temp_croppedFromStart.mp4

    Here’s the command history for 19 & 20

  • ffmpeg generate thumbnails on GPU

    22 juin 2018, par Oleksandr Kyrpa

    I try to generate thumbnails with acceleration on GPU, so compile ffmpeg 3.4.1 and run command :

    ./ffmpeg  -i ~/Videos/1080.mp4 -vf "hwupload_cuda,thumbnail_cuda=100,scale_cuda=107:60,hwdownload,format=yuv420p" -vframes 1 -y ~/Videos/thumbs/thumb%03d.jpg

    But I get wrong output picture (the color of thumbnail is green) :

    enter image description here

    Correct image must be black.
    How to make first image with correct color ?

    enter image description here

    log : -loglevel verbose

    UPDATE, working !
    Add format=nv12 before hwupload

    -vf "format=nv12,hwupload_cuda,thumbnail_cuda,scale_cuda=1280:72‌​0,hwdownload,format=‌​nv12"
