Description
Maybe not a bug but couldn't find better way to submit a request/suggestion(?)
This is a feature request for RealNetworks RealAudio 10 demuxer/codec support,
to properly demux and decode/playback RealMedia 10 encoded audio files/media.
(MPlayer currently get "ERROR mplayer generated exception in decode_audio").
Since RA10 is based on MPEG-4 AAC I guess/hope you can use libFAAD as the base?

(Note! This report is not to be confused with BUG #193 which is for RV10 video)

Same as for bug#193: All information I have indicates that at least on the
decoder side this is the same as RealAudio9, which already is supported
(although unfortunately only via binary codecs).
If you find anything that proves the opposite, reopen.

And what concerns the playback problems: I works fine for me with MPlayer CVS.
Most samples actually are decoded with the opensource faad codec.
So if you have playback problems, please provide a sample (not just links to
pages that contains several samples but the one that doesn't work for you) and
make a proper bugreport (i.e. at least mplayer -v log). For detail see the
bugreports.html file.

I have a rmvb file that mplayer doesn't play. The information given by
AVIcodec is as follows:
Video : 204 MB, 661 Kbps, 25.0 fps, 512*384 (4:3), RV40 = RealVideo 9
Audio : 19.77 MB, 64 Kbps, 32000 Hz, 2 channels, 0x0 = RealAudio 8,raac-0
I think the main problem with this file lies in the raac-0 audio codec.
Mplayer was able to play files with RV40 = RealVideo 9 and RealAudio 8,cook-21
codecs. I would be happy to upload the files if you need it.

Works here. Your mplayer binary or installation seems to be the problem.

Works here with MPlayer CVS, too. It uses the faad decoder to play the audio
btw, could be that
1) your version does not yet include it
2) it was fixed recently

Thanks. Hope the 4CC codes ("raac"/"racp") already been or will added too =)))
PS! Note that this was opened as a feature request, (not as a bug report) ;-)

(In reply to comment #9)
Thanks. Hope the 4CC codes ("raac"/"racp") already been or will added too =)))
Why? I works without that for me, as they are used only in .rm files and are
converted to 'MP4A', which is the one everybody else uses. No idea why real
always thinks it has to do things different.
Or are there any files that need it?

Which created additional confusion because that feature was already there
(especially as I had assumed that you had tried at least the latest release to
see if that feature is already there). You better should have mentioned your
MPlayer version.
"RealAudio 10 : This is a family of audio codecs. New codecs are AAC, RealAudio
Lossless, and RealAudio Multi-channel. RA8 (cook) is used for 96 kbps and
below. HE-AAC in the form of aacPlus from Coding Technologies is included on
Windows" "RealAudio 10 aacPlus (AAC+) is the same as HE-AAC, RealProducer wraps
AAC in RM (.ra) for RealPlayer 10 and ADTS .aac for RealPlayer 10 Gold"
4CC codes for the AAC codec flavors when wrapped in RM:
raac: AAC or HE-AAC
racp: HE-AAC
RealPlayer 10's AAC decoder, raac.dll, can decode both AAC, HE-AAC and Raw ADTS
