Récupération d’informations sur le site maître à l’installation d’une instance

Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;

ffmpeg HLS creation and segmentation results in "cannot decode" on iPad
5 mai 2014, par jt_dylanI have the following code that plays on Mac Safari :
<video controls="controls" width="480" height="270">
<source src="http://d1ckv7o9k6o3x9.cloudfront.net/d54cfa01-eff2-4e86-946e-dc8b2ee4a7e8/media/ hls/MVI_5927.m3u8">
</source></video>The url can be cut/pasted into the browser and works also but neither this code nor the url works in Windows Safari or iPad. Specifically on iPad I receive a cannot decode error. On Mac I have Quicktime installed so I tried that on Windows with no luck. The link that can be play on Mac is below.
http://d1ckv7o9k6o3x9.cloudfront.net/d54cfa01-eff2-4e86-946e-dc8b2ee4a7e8/media/hls/MVI_5927.m3u8
Browser Versions of software :
Mac Safari : Version 7.0.3 (9537.75.14) (works)
Windows Safari : Version 5.1.7 (7534.7.2) (doesn’t work - blank screen)
iPad Safari : ios Version 7.1.1 (doesn’t work - cannot decode)Here is how I’m creating my mp4 (lgpl)
I’m creating an mp4 with this command :
ffmpeg -i input.mov c:v mpeg4 q:v 1 test.mp4I’m creating the hls using ffmpeg lpgl with this command :
ffmpegcmd -re -y -i test.mp4 -map 0 -f segment -segment_list test.m3u8 -segment_list_flags +live -segment_time 1 -segment_list_type m3u8 test%05d.ts 2>&1Now this works in Mac Safari with Quicktime installed but results in "cannot decode" if I try the url from ipad Safari.
I then tried with libx264 to create the mp4 as h.264 with aac and then copy to mpeg2 container as follows :
ffmpeg -i test.mov -c:v libx264 -c:a libfdk_aac -preset slower -b:a 240k test.slower.mp4
ffmpeg -i test.slower.mp4 -vcodec copy -f mpegts -bsf h264_mp4toannexb test.slower.ts
ffmpeg -re -y -i test.slower.ts -map 0 -f segment -segment_list test.slower.m3u8 -segment_list_flags +live -segment_time 1 -segment_list_type m3u8 test.slower.%05d.tsThis still produces the same results. Any idea what is wrong here ?
Any help is much appreciated.
Regards,
jt_dylanOutput from libx264 commands below :
ffmpeg -i test.mov -c:v libx264 -c:a libfdk_aac -preset slower -b:a 240k test.slower.mp4

Error Converting MOV to MP4 (avconv/ffmpeg)
29 avril 2014, par user3584988I use :
avconv -i '/INPUT.MOV' -vcodec libx264 -vprofile baseline -acodec aac -strict experimental -r 24 -b 255k -ar 44100 -ab 59k 'OUTPUT.mp4'The conversion is done correctly and smoothly plays PC / MAC, but the video does not play on mobile devices.
Does anyone have the same problem ? How to solve it ?Thanks in advance

using ffmpeg -f ffmetadata to get metadata for a stream [on hold]
23 avril 2014, par user645402I have a stream that I can get the metadata for using ffmpeg :
ffmpeg -i <stream url="url"> -f ffmetadata -
</stream>This works great for the first song, but then returns. The issue is that the stream is from a radio station which plays song after song - i.e. the metadata is changing as time goes on. However, this command will only give metadata for the song currently playing and then exit.
I would like it to keep flowing the metadata as it updates in the stream.
