Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela. -

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.

How do I properly reduce the resolution of a 360 video using ffmpeg ?
10 avril 2017, par user3799235I have tried reduction with the following technique from a scale of
2048:1024with something like :ffmpeg -i eagle360half.mp4 -vf scale=1024:512 video360_1024.mp4however the playback then becomes warped and warbly (visually similar to a bad vhs tape). I can only speculate that this has something to do with the meridians and equirectangular projections. How would I properly scale/ reduce resolution of a 360 video usingffmpeg, or is this possible with some other cli tool ?Here is the output of mediainfo, ffmpeg, and then mediainfo again :

Error of "Built target opencv_imgproc" while compiling opencv2
23 mars 2017, par HongFollowing https://github.com/menpo/conda-opencv3, while I compile opencv, there is following error (please read the error at the end of the post). The only change I made is to enable ffmpeg by modifying "-DWITH_FFMPEG=1" in BUILD.SH. Any suggestion ?
