MediaSPIP : Modification des droits de création d’objets et de publication définitive
11 novembre 2010, parPar défaut, MediaSPIP permet de créer 5 types d’objets.
Toujours par défaut les droits de création et de publication définitive de ces objets sont réservés aux administrateurs, mais ils sont bien entendu configurables par les webmestres.
Ces droits sont ainsi bloqués pour plusieurs raisons : parce que le fait d’autoriser à publier doit être la volonté du webmestre pas de l’ensemble de la plateforme et donc ne pas être un choix par défaut ; parce qu’avoir un compte peut servir à autre choses également, (...) -
Creating farms of unique websites
13 avril 2011, parMediaSPIP 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" (...) -

unity recorder use at runtime in C#
5 février 2020, par bluejaykeI’m using the unity recorder package in the editor, but I wasn’t sure / didn’t see in the docs if its possible to use the unity recorder package to capture video at runtime — meaning after the project is built to webGL etc., can unity record, and perhaps send / stream the video result to a server ? If not how else would this be accomplished ?

Adding images on both sides of a vertical video using FFmpeg
7 juin 2016, par John DakotaI have a video that I recorded with my phone vertically. When viewing the video on a computer, a large margins on both sides of the video are black. I would like to replace this with an image using FFmpeg.
I read the section on pads on the FFmpeg docs, but it does not say anything about using images as pads (correct me if I’m wrong), it only mentions using colors.

Play UDP live video stream in UWP
19 avril 2018, par Nicolas SévenoI need to display a live video stream in a UWP application.
The video stream comes from a GoPro. It is transported by UDP messages. I think it is a MPEG-2 TS stream.
I can play it successfully using FFPlay with the following command line :
ffplay -fflags nobuffer -f:v mpegts udp://:8554
I would like to play it with MediaPlayerElement without using a third party library.
According to the following page :
https://docs.microsoft.com/en-us/windows/uwp/audio-video-camera/supported-codecs
UWP should be able to play it. (I installed the "MPEG 2 video extension" in the Windows Store).I tried using DatagramSocket and the MessageReceived event to receive the UDP packets, it works without problem :
_datagramSocket = new DatagramSocket();
_datagramSocket.MessageReceived += (s, args) =>
{
Debug.WriteLine("message received");
};
await _datagramSocket.BindServiceNameAsync(8554);Then I create a MseStreamSource :
_mseStreamSource = new MseStreamSource();
_mseStreamSource.Opened += (_, __) =>
{
_mseSourceBuffer = _mseStreamSource.AddSourceBuffer("video/mp2t");
};
this.MediaSource = MediaSource.CreateFromMseStreamSource(_mseStreamSource);And in the DatagramSocket.MessageReceived event I send the messages to the MseStreamSource :
using (IInputStream stream = args.GetDataStream())
{
_mseSourceBuffer.AppendStream(stream);
}The AppendStream method fails with error HRESULT 0x8070000B for some packets.
If I catch the error, the MediaPlayerElement displays the message "video not supported or incorrect file name". (not sure of the message, my Windows is in French).Is the MseStreamSource the correct way to display the stream ? Is there a better solution ?
