Ticket #747 (open enhancement)
Enable AMV encoding for audio
|Reported by:||shimmy||Owned by:|

|Analyzed by developer:||no|
The 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 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I think it would be easy to merge the outdated adpcm_ima_amv encoder from the amv-codec-tools into FFmpeg.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.
