747	Enable AMV encoding for audio	shimmy		"The [http://wiki.multimedia.cx/index.php?title=AMV amv] format is made for chinese s1mp3 hardware players, and is now part of the latest version of FFmpeg (0.9 - Harmony).

However, its underlying audio is adpcm_ima_amv, and this is unsupported by FFmpeg.

When I call {{{ffmpeg -codecs}}}, it contains the line {{{ D A D  adpcm_ima_amv   ADPCM IMA AMV}}}, which means Decoding supported, Audio codec, Direct rendering, but it doesn't contain E which stands for Encoding.

I found the [http://code.google.com/p/amv-codec-tools/w/list amv-codec-tools] project, which supports this audio format automatically.

I think it would be easy to merge the outdated ''adpcm_ima_amv'' encoder from the amv-codec-tools into FFmpeg.

To be noted, compiling amv-codec-tools with the new FFmpeg version doesn't work, even I disable the ''amv'' and the ''adpcm_ima_amv'' encoders/decoders, I get this error: 

{{{
[NULL @ 039a7860] Requested output format 'amv' is not a suitable output format
sample.amv: Invalid argument
}}}

Which is the same error that occurs when trying to use FFmpeg 0.9 for the AMV format - an issue that should be reported separately.

This issue is very urgent to me and I consider promoting a developer that will make it work."	enhancement	open	wish	avcodec	git-master		adpcm_ima_amv	weitzhandler@…			1	0
