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) (...)

HTML5 audio and video support
13 avril 2011, parMediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
For older browsers the Flowplayer flash fallback is used.
MediaSPIP allows for media playback on major mobile platforms with the above (...) -
Support audio et vidéo HTML5
10 avril 2011MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...)

FFMPEG to create an MPEG-DASH stream with VP8
24 avril 2017, par Kenneth WordenI’m trying to use FFMPEG to stream a live video feed from my webcam
/dev/video0. Following scattered tutorials and scarce documentation (is this a known problem for the encoding community ?) I arrived at the following bash script :#!/bin/bash
ffmpeg \
-y \
-f v4l2 \
-i /dev/video0 \
-s 640x480 \
-input_format mjpeg \
-r 24 \
-map 0:0 \
-pix_fmt yuv420p \
-codec:v libvpx \
-s 640x480 \
-threads 4 \
-b:v 50k \
-tile-columns 4 \
-frame-parallel 1 \
-keyint_min 24 -g 24 \
-f webm_chunk \
-header "stream.hdr" \
-chunk_start_index 1 \
stream_%d.chk &
sleep 2
ffmpeg \
-f webm_dash_manifest -live 1 \
-i stream.hdr \
-c copy \
-map 0 \
-f webm_dash_manifest -live 1 \
-adaptation_sets "id=0,streams=0" \
-chunk_start_index 1 \
-chunk_duration_ms 1000 \
-time_shift_buffer_depth 30000 \
-minimum_update_period 60000 \
stream_manifest.mpdWhen I run this script, my webcam light turns on, the
stream.hdrandstream_manifest.mpdfiles are written, and chunks start to be created (i.e.stream_1.chk,stream_2.chk, etc...). However, FFMPEG throws the following error :Could not write header for output file #0 (incorrect codec parameters
?) : Invalid data found when processing inputI will explain what I think I am doing with this script, and hopefully this will expose any errors in my thinking.
First, we invoke FFMPEG to use Video for Linux 2 (v4l2) to read from my webcam (
/dev/video0) of a resolution 640x480. The input format ismjpegwith a framerate of 24fps.I then declare that FFMPEG should "map" (copy) the video stream output by v4l2 to a file. I specify the pixel format (YUV420P) and use libvpx (VP8 encoding) to encode the video stream. I set the size to be 640x480, use 4 threads, set the bitrate to be 50kbps, do some magic with tile-columns and frame-parallel options, and set the I-frames to be 24 frames apart.
I then create a
stream.hdrfile. The starting index is 1. This command continues to run infinitely until I kill it, grabbing new video from my webcam and outputting it into chunks.I then sleep for 2 seconds to give the previous command time to generate a header file.
And that’s really it. The next invocation of FFMPEG simply creates the MPEG-DASH manifest file given the header generated in the previous step.
So what’s going on ? Why can I not view the video in a web browser (I’m using Dash.js) ? I serve the manifest, header, and chunks on a Node.js server so that trivial issue is not the problem.
Edit : Here is my full console output.

If so, could I avoid the transcoding by command ? Or it is a necessary ?
It it is a need, WHY ? -
Launching ffmpeg from inside my C code doesn't convert video stream from fifo
13 mai 2017, par abraxas1(Beaglebone Black, ubuntu 16.04 linux 4.4.62-ti-r99)
I have a raw h264 feed coming into my C program (into a callback from a custom API) and then I named-piped the raw h264 to a file and this CLI command converts that file successfully.
ffmpeg -report -re -framerate 30 -y -f h264 -i orbi_0148.cam1.h264 -c:v copy -an -video_size 1920x1080 -f mp4 orbi_0148.cam1-1.mp4
I then try to launch this command from my program with the same options using execv(),
first mkfifo the fifo’s,
then launch ffmpeg (shown below) starts the streaming form the cameras to my callback function, and out to the fifos.
I close the fifos at the end of video recording, and don’t get any file created and get this output, which I don’t understand at all.
(the successful command line output follows below this output generated from execv())
thanks, any help much appreciated.
hardware has come in now and the spot light is on me.(execv output with options -report -y -i /tmp/fifocam3.h264 -c:v copy -an -video_size 1920x1080 -f mp4 /media/sd-card/orbi_0140.cam3.mp4)
