Hi,
 
I've tried to use the Helix DNA Server in order to stream a 3gp file with
H263 & NB-AMR tracks.
The SDP that returns as answer to the DESCRIBE request specifies the tracks
as video/X-RN-3GPP-H263 & audio/X-RN-3GPP-AMR instead of the standard
video/H263-2000 & audio/AMR.
That fails players other than RealPlayer from accepting the streams.
 
I've found out that if I change the strings that pMediaName accepts in
switch-case at CQT_TrackInfo_Manager::InitNonHinted
(datatype/mp4/fileformat/qtatmmgs.cpp) than it influence the produced SDP.
Nevertheless, when doing so, the players don't play correctly (doesn't
display the video and produce noise from the audio). From sniffing and
looking at the RTP content it seems the same as before (that played with
RealPlayer) though.
 
Bug #5121 discuss the issue of the non-standard mime-types at the SDP
(despite it's summery description). This bug was created on July but still
left at status 'NEW'.
 
Regards,
Assaf Y.
