[FFmpeg-user] Failed installing FFMPEG on CentOS

Wed Nov 29 11:02:27 EET 2017

Hi Carl and Moritz,

Thanks for your assist earlier on, but still the solution couldn't work out.

I'm not using a pre-installed binary.

The binary should have been created when I initially run ./configure without
any parameters.

Now I run the following commands:

./configure --enable-gpl --enable-libmp3lame

make install

Attached are the results of the command line execution.

I would like to highlight the ffmpeg folder does not contain the libmp3lame
subfolder; could this be the problem?

Here's my folder listing:

The command line was last run on 28-Nov. The ffmpeg binary is 11-Nov, so it
should have been created earlier on.

If you didn't manage to compile ffmpeg (the output from make tells me it
cannot have created a binary), how did you manage to execute ffmpeg
afterwards? Are you actually running a pre-installed binary instead?

Please confirm that you are trying to build current FFmpeg git head

(nothing else is supported here) and that you are using a sane configure

line like "./configure --enable-gpl --enable-libmp3lame".

Missing configure option "--enable-libmp3lame"
