    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 doesn't recognize Quicktime DV codec

    8 août 2017, par 3pointedit

    I have had success with excellent advice, on a Mac OSX10.5, converting a modified MXF media structure to h264 while retaining multitrack audio. But I cannot get ffmpeg to work in Windows environment.

    See this page.

    Here’s the result of latest failure-

  • FFmpeg concat produces bad Video

    6 mars 2019, par Amorphis

    I have installed ffmpeg on a microsoft/dotnet:2.2-aspnetcore-runtime docker container using
    1.apt-get update
    2.apt-get install ffmpeg.

    seems to be installed fine, but when I try and use it as such
    ffmpeg -f concat -i /data/mylist.txt -c : copy /data/output.mp4

    the output is that the first video part is ok, but the second colors are all messy (hard to explain) and when I change the order of the videos in the list still the first in the list is ok and the second is messed up.

    p.s same settings on a different machine works (ffmpeg for ubuntu)

  • Is there a set of working P/Invoke declarations for FFMpeg, libavutil, libavformat and libavcodec in .NET ?

    11 février 2014, par casperOne

    I'm currently looking to access libavutil, libavformat and libavcodec (all part of FFMpeg) from .NET.

    Currently, I'm getting the libraries from the automated builds of the shared FFMpeg package performed every night for Windows 32-bit.

    I am also using the code from the ffmpeg-sharp project. In that project, I have removed a number of classes that were not compiling (they are wrapper classes not the P/Invoke declarations).

    The code compiles fine, but I am running into a few issues.

    First, it appears that the build of av*.dll uses the cdecl calling convention, as I was receiving a number of PInvokeStackImbalanceException when trying to call av_open_input_file. This was easy enough to change to get it to work right. The AVFormatContext structure is populated.

    After that, I want to call av_find_stream_info to get information about the streams in the file. However, when calling that with the AVFormatContext retrieved from the call to av_open_input_file, an AccessViolationException is thrown indicating that I am trying to read or write from protected memory.

    Has anyone used P/Invoke to access the libavutil, libavformat and libavcodec dll libraries through P/Invoke and have gotten it to work ?

    I should mention that working with the command-line version of FFMpeg, while a solution, is not a viable solution in this case, access needs to occur through the libraries. The reason for this is that I'd have to thrash the disk way too much to do what I need to do (I have to do a frame-by-frame analysis of some very high definition video) and I want to avoid the disk as much as possible.
