ASF WMA Questions, best place to ask?

Hi, I'm not sure if I'm in the right subForum let alone forum on the internet for discussing a technical problem I have with decoding a WMA/ASF encoded Audio Stream Via RSTP/RTP...

So assuming there is a better place to ask, my question is where should I best be hanging out for this sort of discussion?? as below:

which is resulting in strange Clicks/Peaks/Glitch Sounds that don't sound very good when Streaming. And I'm not sure but I have a hunch I've made a mistake stripping the header ( rtp_asf_fix_header )

I'm struggling to pin point why I'm getting Frame Corruption with various errors in console such as:

[wmav2 @ 0x6030200]frame_len overflow
[wmav2 @ 0x6030200]frame_len overflow
2010-10-30 23:20:33.949 RTSP[25908:9d03] -[WMADecoder decodeThread] Packet failure rate is 9.677419 with 31 packets
2010-10-30 23:20:33.949 RTSP[25908:9d03] -[WMADecoder decodeThread] !!!!!Error decoding packet!!!!!

AND

2010-10-30 23:20:33.934 RTSP[25908:9d03] -[WMADecoder decodeThread] Packet read of size 1920
[wmav2 @ 0x6030200]overflow in spectral RLE, ignoring



And Finally

2010-10-30 23:20:35.533 RTSP[25908:6713] -[InternalPCMStreamer handlePropertyChangeForQueue:propertyID:] AudioQueue changed state in unexpected way.

Most of those errors just mean you passed the WMA decoder data it didn't understand, so I would guess that something is wrong with your parser.

FWIW when troubleshooting ASF errors, I usually dump the entire frame to disk, and then compare to the dump produced by MS's "ASF view 9" tool.
