Ffmpeg (debian) not seeing libx264 presets?

Question

fmpeg

I put ffmpeg from sorts and libx264 from sorts too, everything is kosher.
I'm trying to convert a file:

ffmpeg -y -i House.M.D.s08e03.rus.LostFilm.avi -acodec libfaac -ac 2 -ab 96k -ar 44100 -vcodec libx264 -vpre /root/ffmpeg/ffpresets/libx264-normal.ffpreset -g 100 -keyint_min 50 -b 300k -bt 300k -threads 2 house-q1.mp4

I get:

<u>File for preset '/root/ffmpeg/ffpresets/libx264-normal.ffpreset' not found</u><br/>

Well, that is, if you specify it simply -vpre normaldoes not find it either. But then I gave him the file.
Anyone can help?

Answer 1

you must do -fpre for the full path, or -vpre to search in one of the preset paths.
But you don't have to do all this anymore, because ffmpeg has abandoned its presets in favor of libx264 presets

Answer 2

And why did you build it, and not install it from the repository?
apt-get ffmpeg - or something like that

Answer 3

/root/ffmpeg/ffpresets/libx264-normal.ffpreset

Are you doing this from root? Do not do it this way.
And about -vpre, we would look at the help:
-vpre preset set the video options to the indicated preset
I.e. you need to create this file and put the required video settings there.

Answer 4

On Windows builds, this also happened: I could not find presets and gave out corrupted x264.
After some time I updated, everything worked.

Answer 5

There is an option to explicitly specify the preset file, this may help without solving this problem.

Answer 6

Can you explain why you don't include ffmpeg's own presets (which are in /usr/share/ffmpeg/)?
Or did you install it somehow crookedly?
