[Ffmpeg-devel] OS X 10.4.1 + AMR NB Support (success finally)

[Henry Junior]

Thank you very much for your help, I finally got it working.  Here's
what I had to do:

(1) downloaded ffmpeg:

	cmd in terminal:
	cvs -z9 -d:pserver:anonymous at mplayerhq.hu:/cvsroot/ffmpeg co ffmpeg

(2) downloaded AMR codecs from 3GP

	a. downloaded:
http://www.3gpp.org/ftp/Specs/2004-03/Rel-5/26_series/26073-530.zip
		-unzipped the folder 
		-open the extracted folder and unzipped the included file
(26073-510_ANSI-C_source_code.zip)
		-rename the folder 26073-510_ANSI-C_source_code Folder to amr 
		-moved amr folder to libavcodec folder in ffmpeg 
	
	b. downloaded:
http://www.3gpp.org/ftp/Specs/2004-03/Rel-5/26_series/26104-540.zip
		-unzipped the folder 
		-open the extracted folder and unzipped the included file
(26104-510_ANSI_C_source_code.zip)
		-rename the folder 26104-510_ANSI_C_source_code Folder to amr_float 
		-moved amr_float folder to libavcodec folder in ffmpeg 

(3) created config.mak and config.h files:

	cmd in terminal:
	./configure --enable-amr_nb

(4) changed Makefile in AMR in regards to response from results in #4
	
	this is what i changed in libavcodec/amr/makefile:

		from: 
		CFLAGS = -Wall -pedantic-errors -I. $(CFLAGS_$(MODE)) -D$(VAD)
		
		to:
		CFLAGS = -Wall -DMMS_IO -I. $(CFLAGS_$(MODE)) -D$(VAD)

(5) make the application

	cmd in terminal:
	make

(6) install:

	cmd in terminal:
	make install
	
(7) test:
	
	/usr/local/bin/ffmpeg -i path/to/file.wav -acodec amr_nb -ar 8000 -ab
23.85 /path/to/newfile.amr
