Librairies et logiciels spécifiques aux médias
10 décembre 2010, parPour un fonctionnement correct et optimal, plusieurs choses sont à prendre en considération.
Il est important, après avoir installé apache2, mysql et php5, d’installer d’autres logiciels nécessaires dont les installations sont décrites dans les liens afférants.

FFmpeg - downmixing FLAC 6.1 to AAC 5.1
7 juillet 2014, par MartijnI can’t seem to figure out how to do this. I’ve been staring at these commands :
https://trac.ffmpeg.org/wiki/AudioChannelManipulationBut to no avail. It’s a tad above my level, sadly. Here’s the ffmpeg -i output for the video in question :

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 :
...

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 ?

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

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 ?
