Is it possible to use the ffmpeg binary within the ffmpegx package contents, as a command line program? I would like to convert a WAV audio file to WMA and ffmpeg is supposedly able to do that (didn't see it in ffmpegx), but I'm trying to avoid compiling my own. Normally I'm pretty competent with computers, but I'm a total stranger to UNIX so go easy on me.
Try StreamFab Downloader and download from Netflix, Amazon, Youtube! Or Try DVDFab and copy Blu-rays! or rip iTunes movies!

The copy of ffmpeg in ffmpegX may be compiled without the WMA encoding options. Not sure if major did that, but I couldn't get it to work either.
The -formats option lists only decoding ability for wmav1 and wmav2. -
A regular "Audio file to mp3" conversion would go something like:
Code:ffmpeg -i in.wav -y -threads 2 -vn -f mp2 -acodec mp3 -ab 128 -ar 44100 -ac 2 -map 0.0:0.0 -benchmark out.mp3
ffmpeg (the program that should be activated and use the following parameters)
-i in.wav (input file)
-y (overwrite output files)
-threads 2 (thread count)
-vn (disable video)
-f mp2 (force format)
-acodec mp3 (force audio codec)
-ab 128 (set audio bitrate)
-ar 44100 (set audio sampling rate)
-ac 2 (set number of audio channels)
-map 0.0:0.0 (set input stream mapping)
-benchmark (add timings for benchmarking)
out.mp3 (output file)
The input file and output file should be full path in most cases, as the home directory is default.
As ffmpeg isn't installed in /usr/bin/ or so, it should be identified with the full path, too.
To do so in the Terminal, you may use drag-and-drop.
Some of the command line options listed above aren't strictly needed:
- audio sampling rate defaults to same as source if such is valid
- number of audio channels defaults to same as source if such is valid
- stream mapping 0.0:0.0 is default
- benchmarking can be skipped -
I understand running commands and using arguments and so forth (I used to play with DOS a lot), but I'm having trouble getting up to that point.
Here's what I've done.
1. right-click ffmpegx app, and choose Show Package Contents.
2. open Contents/Resources
3. copied "ffmpeg" file into a new folder on HD
4. Launched "Terminal" and navigated to folder containing the "ffmpeg" UNIX executable file.
5. Type "ffmpeg" with and without various arguments at the prompt, and all I get is "command not found"
What am I doing wrong? -

I did this way.
Open a terminal from administrator account
cd /usr/bin
sudo ln -s /Applications/ffmpegX.app/Contents/Resources/ffmpeg .
be carefull to write the last dot
It makes a link in your /usr/bin/ folder to ffmpeg (just doublecheck that the folder has the same name in your computer.
once it's there you can run ffmpeg from everywhere in the shell.
if you are not amministrator you still can make a link in your home directory
ln -s /Applications/ffmpegX.app/Contents/Resources/ffmpeg .
to run it from the directory it is:
./ffmpeg
if you put it in /home/you/bin you can call it
~/bin/ffmpeg
hope I've helped -
That worked. Thanks Stefano!
I didn't even know the 'usr' directory existed. Is there some way to open it from Finder? -
Actually, I see WMAV there under codecs, which would suggest ffmpeg could encode and decode it.

I see. So I'm guessing Finder is configured never to show these folders, and not even give you the ability to set their visibility? What if I wanted to hide my own folder ... I do it from the command line with like an 'h' attribute or something?

So I'm in the process of compiling ffmpeg
I tried to follow the guide here:
http://stephenjungels.com/jungels.net/articles/ffmpeg-howto.html
I've make'd the faac, faad and lame libraries. They're in my usr/local/bin directory.
I'm at the step of configuring ffmpeg using this command:
Code:./configure --enable-libmp3lame --disable-vhook --enable-shared --disable-mmx --enable-libfaac --enable-libfaad --enable-gpl
Code:ERROR: LAME not found If you think configure made a mistake, make sure you are using the latest version from SVN. If the latest version fails, report the problem to the ffmpeg-user <at> mplayerhq.hu mailing list or IRC #ffmpeg on irc.freenode.net. Include the log file "config.err" produced by configure as this will help solving the problem.

-
OK looks like I just had to put the lame.h include file in a lame subdir.
Now I get a new error during the make.
Code:make(20468) malloc: *** vm_allocate(size=4272963584) failed (error code=3) make(20468) malloc: *** error: can't allocate region make(20468) malloc: *** set a breakpoint in szone_error to debug make: *** virtual memory exhausted. Stop.

The 'make' did not finish and gave an error:

Good job, impressive! Any idea what ability you loose by taking out --enable-shard ?
