BBC iPlayer HQ stream

[motd2k]

I've modified rtmp.cpp to enable me to open BBC iPlayer's High Quality MP4 streams, i've authenticated, and the server has initiated stream playback, however i'm dropping out with this...

It would appear that ffmpeg is choking on the audio, anyone have any suggestions?

Great work, I'd be interested in your changes as I couldn't get a connection when I tried something similar a while ago. If you've had no joy with playback yet, and can drop me a diff I'll probably have time over xmas to have a look myself.

A suggestion could be to dump everything returned from CDVDInputStreamRTMP::Read to file, as it should be a valid FLV video file. That can be examined in your favourite player or checked manually against the flash spec (which, thank god, is properly documented unlike rtmp). Version 9 here: http://www.adobe.com/devnet/flv/pdf/video_file_format_spec_v9.pdf

I dumped this file as suggested, and initially had problems opening it in any external application - vlc, mplayerc etc. After installing the latest CCCP beta (http://www.cccp-project.net/beta/), it will now open in Media Player Classic.... which detects the following...

Video: MPEG4 Video (H264) 640x368 [Video]
Audio: AAC 44100Hz stereo [Audio]

It would therefore seem that its certainly an ffmpeg issue. I'm using AreaScout's branch, and so my dvdplayer is actually using a fairly recent FFmpeg. I guess i'll seek help on their boards.
