  • 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" (...)

  • FFMPEG not enough data (x y), trying to decode anyway

    7 juin 2016, par Forest J. Handford

    I’m trying to make videos of Direct3D games using a C# app. For non-Direct3D games I stream images from Graphics.CopyFromScreen which works. When I copy the screen from Direct3D and stream it to FFMPEG I get :

    [bmp @ 00000276b0b9c280] not enough data (5070 < 129654), trying to
    decode anyway

    An MP4 file is created, but it is always 0 bytes.

    To get screenshots from Direct3D, I am using Justin Stenning’s Direct3DHook. This produces images MUCH bigger than when I get images from Graphics.CopyFromScreen (8 MB vs 136 KB). I’ve tried increasing the buffer (-bufsize) but the number on the left of the error is not impacted.

    I’ve tried resizing the image to 1/6th the original. That reduces the number on the right, but does not eliminate it. Even when the number on the right is close to what I have for Graphics.CopyFromScreen I get an error. Here is a sample of the current code :

    When I search the internet for the error all I get is the FFMPEG source code, which has not proven to be illuminating. I have been able to save the image directly to disk, which makes me feel like it is not an issue with disposing the data. I have also tried only grabbing one frame, but that produces the same error, which suggests to me it is not a threading issue.

    Any ideas would be greatly appreciated. My current workaround is to save the files to the HDD and compile the video after gameplay, but it’s a far less performant option. Thank you !

  • ffmpeg mapping to mkv introduces "fake" delay relative to video

    1er août 2016, par JMor

    I need to map this x.264 clip into a matroska container using ffmpeg :

    ffmpeg -i f-0.mp4 -c copy f-0.mkv

    Here is the ffmpeg console output :

    ffmpeg -i f-0.mp4 -c copy f-0.mkv

    The result seems good, playing with well synchronized audio and video. However, MediaInfo shows a new item under Audio (that the original clip didn’t have) :

    Delay relative to video                  : 1mn 5s

    Here is the Mediainfo from the original f-0.mp4 file :

    There is no delay whatsoever and no reason to insert a delay.

    I am concerned that this information (Delay relative to video) be used by some players or other applications as a delay that should be corrected. Is there a way to prevent this from happening ?
