  • De l’upload à la vidéo finale [version standalone]

    31 janvier 2010, par

    Le chemin d’un document audio ou vidéo dans SPIPMotion est divisé en trois étapes distinctes.
    Upload et récupération d’informations de la vidéo source
    Dans un premier temps, il est nécessaire de créer un article SPIP et de lui joindre le document vidéo "source".
    Au moment où ce document est joint à l’article, deux actions supplémentaires au comportement normal sont exécutées : La récupération des informations techniques des flux audio et video du fichier ; La génération d’une vignette : extraction d’une (...)

  • Saving Uncompressed Video Files using OpenCv, Gstreamer, and/or FFMPEG ?

    21 septembre 2022, par adav0033

    I have been trying to implement the cv::VideoWriter function from OpenCV to generate a an uncompressed video file. I started this because of a statement within the OpenCV Documentation which I will link here along with the statement.

    


    cv::VideoWriter::VideoWriter    (   const String &  filename,
int     fourcc,
double  fps,
Size    frameSize,
bool    isColor = true 
)       


    


    "If FFMPEG is enabled, using codec=0 ; fps=0 ; you can create an uncompressed (raw) video file."

    


    Ref. https://docs.opencv.org/3.4/dd/d9e/classcv_1_1VideoWriter.html

    


    However whilst troubleshooting the function I came across the refuting statement,

    


    " VideoCapture and VideoWriter do not provide interface to access raw compressed video stream, except maybe MJPEG in some cases.
Make sure you actually use FFmpeg backend by setting apiPreference parameter : VideoWriter("outfile.avi", cv2.CAP_FFMPEG, ...)"

    


    Ref. https://github.com/opencv/opencv/issues/14573

    


    I am now confused about how I go about writing the cv::VideoWriter function to satisfy the requirements to create an uncompressed video file (.avi) and if it is even possible. If it is not possible how do I achieve the outcome of saving an raw uncompressed video file, as I assume it would use some combination of FFMPEG, OpenCV,or Gstreamer.

    


    Note : My code is implemented in c++

    


  • How to Add Gstreamer Plugin on Mac when installed from Tutorials

    31 juillet 2014, par Dave Collins

    I basically have two installs of gstreamer on my Mac OS X machine :
    The one that works perfectly was installed following this tutorial (http://docs.gstreamer.com/display/GstSDK/Installing+on+Mac+OS+X) and downloading and installing the Developer SDK and using XCode. All tutorials work well.

    I also have a local version installed with Homebrew but video playback does not work on that version (see SO : gstreamer gst-launch sample mac osx plays audio but not video)

    SO, I’m trying to install the FFMPEG plugin into the working xcode dev system so that I can use FFDEC_H263 in a project.

    I tried simply copying the related .SO files (e.g. libgstffmpg.so) from the homebrew (cellar) location to the

     /Library/Frameworks/GStreamer.Framework/Versions/0.10/lib/gstreamer-0.10/

    directory and changing permissions. However, that gives me a "Caught a segmentation fault while loading plugin file" error when building any code.

    I also noticed that in the Xcode directory mentioned above, all of the plugins have a related .a and .la files in the \static subdirectory... Those same files don’t exist in the homebrew version.

    So, what is the proper way to install a plugin when you’ve started with the developer SDK for Mac OSX ?

    I see a response like this, When I use OBS to stream to this RMTP URL it doesn’t have the title I set in the stream as you can see come in response. I am getting stream name but not sure if I do it correctly.

    If I call the path as rtmp://a.rtmp.youtube.com/live2/steamnamefromurl/mykey
    it’s work but not have the title I set by call API. Anyone please check the page and help what I am going wrong. What I am looking for is get the title and description set for stream, or verified that I am doing it correctly.
