Support de tous types de médias
10 avril 2011Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

D’autres logiciels intéressants
12 avril 2011, parOn ne revendique pas d’être les seuls à faire ce que l’on fait ... et on ne revendique surtout pas d’être les meilleurs non plus ... Ce que l’on fait, on essaie juste de le faire bien, et de mieux en mieux...
La liste suivante correspond à des logiciels qui tendent peu ou prou à faire comme MediaSPIP ou que MediaSPIP tente peu ou prou à faire pareil, peu importe ...
On ne les connais pas, on ne les a pas essayé, mais vous pouvez peut être y jeter un coup d’oeil.

Supporting all media types
13 avril 2011, parUnlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible. The following are just a few examples from an ever-expanding list of supported formats : images : png, gif, jpg, bmp and more audio : MP3, Ogg, Wav and more video : AVI, MP4, OGV, mpg, mov, wmv and more text, code and other data : OpenOffice, Microsoft Office (Word, PowerPoint, Excel), web (html, CSS), LaTeX, Google Earth and (...)

Using GStreamer to receive and send h264 video (from OBS)
16 mars 2020, par IvoriusI’ve been trying to set up using GStreamer to get support for some input I can output from OBS.
OBS : rtp_mpegts to udp ://localhost:5000
http-launch 8080 webmmux streamable=true name=stream udpsrc uri=udp://localhost:5000 caps="application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)MP2T-ES, payload=(int)
33" ! gstrtpjitterbuffer latency=200 ! application/x-rtp ! rtpmp2tdepay ! video/mpegts ! mpegtsdemux ! video/x-h264 ! queue ! decodebin ! vp8enc ! stream. audiotestsrc ! vorbisenc ! stream.However, using this it seems to accept connections, but just closes them again after a while. Any clues on what I am doing wrong ? I am open to any format changes as long as they’re supported by OBS / ffmpeg.
As a bonus, how do I add support for audio as well ?
Background
I’ve found https://github.com/sdroege/http-launch, which works well in displaying a GStreamer video over http:
<video autoplay="autoplay" controls="">
<source src="https://localhost:8080" type="video/mp4" codecs="avc1.4D401E, mp4a.40.2">
You browser doesn't support element <code>video.
I’ve managed to set up a pipeline where I can use a GStreamer source to pipe into a http-launch
pipeline and display it on video :http-launch 8080 webmmux streamable=true name=stream udpsrc port=5000 caps = "application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264, payload=(int)96" ! mpegtsdemu
x ! h264parse ! TIViddec2 ! videoconvert ! vp8enc ! stream. audiotestsrc ! vorbisenc ! stream.
gst-launch-1.0 -v videotestsrc ! videoconvert ! x264enc tune=zerolatency bitrate=500 speed-preset=superfast ! rtph264pay ! udpsink host=127.0.0.1 port=5000However, I don’t think OBS supports rpt over UDP. It uses ffmpeg to send these packets, which can stream rtp_mpegts. I’ve found some code snippets which claim to support the format, and stitch together the above pipeline.

x86util : import MOVHL macro
11 février 2017, par James Darnleyx86util : import MOVHL macro
Originally committed to x264 in 1637239a by Henrik Gramner who has
agreed to re-license it as LGPL. Original commit message follows.x86 : Avoid some bypass delays and false dependencies
A bypass delay of 1-3 clock cycles may occur on some CPUs when transitioning
between int and float domains, so try to avoid that if possible. -

* cus/stable :
ffplay : factorize thread starting and stopping code into decoder
ffplay : make eof part of videostate and signal it when opening a stream
