Hi,

I'm trying to figure out why UDP streaming doesn't work. I'm using the 9.11 release source, but I've tried this also with the latest nightly builds and confirmed it is still broken. I've seen a few postings about this lately in the user forums with no real solutions. I'm trying to stream an MPEG-2 TS over UDP. I've created a .strm file with udp://127.0.0.1:6666. I'm sending the stream from VLC. VLC can also receive this, but XBMC fails. The relevant part of the log is below.

I've traced the failure to the following call in CDVDDemuxFFmpeg::Open(CDVDInputStream* pInput):

if( m_dllAvFormat.av_open_input_file(&m_pFormatContext, strFile.c_str(), iformat, FFMPEG_FILE_BUFFER_SIZE, NULL) < 0 )

Any suggestions on how I can best debug this when it is failing inside the DLL? Anybody know why UDP streaming doesn't work?

Thank you.

Actually, (to answer my own question five minutes after I posted) I think this is one part due to Ticket #9496 "Can't play an UDP unicast stream". The second part is that I had tried to use multicast addresses, but I didn't realize that a multicast address needs to have the @ in the URL (udp://@239.255.168.8:1234). I think I can work around Ticket #9496 for what I'm trying to do.

Thanks anyway.

Weird that it needs an @ in the url. That seems odd.
