Can't find preset files
1er juin 2012, par Bilthonthis is a ffmpeg issue. I've got this error saying it could not find the hq preset file, then I read in the documentation that it looks for the preset files at 'PREFIX/share/ffmpeg' and also at '$HOME/.ffmpeg'. The thing is I'm calling ffmpeg from whithin a php file that calls a python script that finally executes the command something like 'commands.getstatusoutput(command)' so I was not sure who the user was.
The solution ? I just used -fpre and my call now looks like this :
/usr/local/bin/ffmpeg -i ../files/tmpvideos/myStream.flv -y -acodec libfaac -ab 96k -b 800k -maxrate 800k -minrate 600k -bufsize 800k -s 720x640 -vcodec libx264 -g 300 -r 20 -fpre /home/admin/.ffmpeg/libx264-hq.ffpreset -threads 0 ../files/tmpvideos/4647-60.mp4
I created that directory under /home/admin and am 100% sure that there the file is there now, but still ffmpeg says :
File for preset '/home/admin/.ffmpeg/libx264-hq.ffpreset' not foundSo I'm not sure why is it not working since I'm specifying the complete path now. Any ideas ?
One reason that I'm thinking of, is that it maybe was not compiled correctly, like with all the flags and stuff. What I mean is that while some outputs out there looked like this :

libswscale 0.10. 0 / 0.10. 0mine looks more like this :

libavdevice 52. 2. 0 / 52. 2. 0
libswscale 0.11. 0 / 0.11. 0No configuration stuff. What do u think ? could be that this ffmpeg was not compiled correctly so it will never find the presets ? I didn't compile it, so can't be sure.
Thanks and sorry for the verbosity of the question.
