[issue1912] WMAPro-in-WMAVoice support not implemented
Ronald S. Bultje rsbul...@gmail.com added the comment:
Attached patch does the initialization of proper contexts for support of
WMAPro-in-WMAVoice. The actual decoding doesn't work yet because the
call to avcodec_decode_audio() is missing. Init fails though:
[wmapro @ 0x101855200] no length prefix
If you want to help, upload a sample of this file to
ftp://upload.ffmpeg.org/MPlayer/incoming/ and contact the ffmpeg-devel
mailing list.
basically, once done correctly, the proper thing to do is to use
ff_copy_bits() to re-align, then call the WMAPro decoder, count the
number of bits read and then go back into the WMAVoice decoder and
subtract that number of bits (not bytes) off of the bit context.
Shouldn't be too hard once I know what to do with the WMAPro decoder
init.
