ffmpeg: Unrecognized option 'crf'. Error splitting the argument list: Option not found
Solution 1
Your ffmpeg
is not from the Ubuntu 17.10 repo and looks like it was compiled on your machine. It lacks --enable-gpl --enable-libx264
which is required to use -c:v libx264
. Unrelated, but it has --disable-x86asm
which is never recommended as it will result in slowness.
You have several options to fix this:
Use the ffmpeg package from the repo:
sudo apt-get install ffmpeg
Download a recent compiled
ffmpeg
binary and put it in/usr/local/bin
or~/bin
.Follow the Ubuntu guide on the FFmpeg Wiki to compile
ffmpeg
.
Solution 2
In my case was anaconda3 which my system was calling ( and installling, removing, etc didn't fix my problem), you could find out if it is your case with:
whereis ffmpeg
After that I saw all the possible path, the system was calling conda
version instead of system
version. To be sure you have a compatible version with --crf
install it with:
sudo apt-get install ffmpeg
then for calling with it, you should use the path from the system or modify your PATH variables (this is modify ~/.profile
or ~/.bash
or more options and how it works here). I didn't do that because everything works with ffmpeg conda version except the --crf
argument.
How to use the compatible version with --crf
/usr/bin/ffmpeg -i input.mp4 -vcodec libx265 -crf 28 output.mp4
Where /usr/bin/ffmpeg
is a one of the results of whereis ffmpeg

R S over 6 years@Mulvya done, take a look, please.
-
Gyan over 6 yearsYou need a ffmpeg binary with libx264 included. Get it from johnvansickle.com/ffmpeg
-
R S over 6 years@Mulvya thanks, also I would appreciate if someone knows how to make it work with usual build.

Elisa Cha Cha over 6 years@RS Your version
N-90232-g0645698ecc
is not from the repo. It looks like a compiled version. See trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu for compile guide, or just use the actual ffmpeg package from the repo.

Elisa Cha Cha almost 6 years@VivekMishra I don't know anything about bravobit android dependencies. I recommend asking a new question.
