Les vidéos
21 avril 2011, parComme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...) -
Keeping control of your media in your hands
13 avril 2011, parThe vocabulary used on this site and around MediaSPIP in general, aims to avoid reference to Web 2.0 and the companies that profit from media-sharing.

FFMPEG latest version for Wamp or Xampp
28 septembre 2014, par Ÿüšhä KĥãnI have seen the php ffmpeg project
http://sourceforge.net/projects/ffmpeg-php/files/
the last version was 0.6 in 2008 but I need ffmpeg 1.8 to work on a video sharing script. SO I googled it but came with no results. Anyone know how can I get the php_ffmpeg.dll (for windows i mean) latest version for working with it on my localhost on wamp or xampp ? -
getting errors from FFMpeg when spawned from .NET
18 mars 2014, par BrannonWhen I run FFMpeg from the command line like this
ffmpeg.exe -hwaccel auto -re -i "C:\Users\Public\Videos\Sample Videos\Wildlife.wmv" -an -sn -c:v bmp -pix_fmt bgr24 -f rawvideo - > junk.binit works fine. However, when I spawn the exact same thing (minus
> junk.bin) I get this nasty "bad header" error after a few seconds of playback. What is causing this ? I have trouble believing my process blocks the pipe longer than the filesystem does, but it should be able to block the pipe indefinitely without defeating the decoding. The truncated stderr is below. My code to spawn the thing is here.ffmpeg version N-60761-g916a792 Copyright (c) 2000-2014 the FFmpeg developers

mimetype : application/x-truetype-fontAs you can see, one of the streams is a FLAC 6.1 stream. I wanted to convert that to AAC, and I know how to do that, basically like this :
ffmpeg -i "input.mkv" -codec:v copy -codec:a aac -strict -2 -b:a 320k -f matroska "output.mkv"But apparently AAC doesn’t support 6.1 audio :
...
[aac @ 03b26860] Unsupported number of channels: 7
Output #0, matroska, to 'd:\Movies\[Coalgirls]_Spirited_Away_(1920x1038_Blu-ray_FLAC)_[92372194].aac.mkv':
Stream #0:0(jpn): Video: h264, yuv420p10le, 1920x1038 [SAR 1:1 DAR 320:173], q=2-31, 23.98 fps, 90k tbn, 1k tbc (default)
Stream #0:1(jpn): Audio: aac, 0 channels, 128 kb/s (default)
Metadata:
encoder : Lavc55.67.100 aac
Stream #0:2(eng): Subtitle: ssa, 128 kb/s (default)
Metadata:
encoder : Lavc55.67.100 ssa
Stream mapping:
Stream #0:0 -> #0:0 (copy)
Stream #0:1 -> #0:1 (flac (native) -> aac (aac))
Stream #0:9 -> #0:2 (ssa (native) -> ssa (native))
Error while opening encoder for output stream #0:1 - maybe incorrect parameters such as bit_rate, rate, width or heightThat’s fine, so I wanted to downmix it to 5.1 and encode as AAC. But I can’t seem to work out how to. Any advice ?
