Hi ALL, 

I used the "testOnDemandRTSPServer" for my streaming project, the video
streaming seems working fine, but  the  testOnDemandRTSPServer program
kept post  warning message on my screen as followings:

MPEG4VideoStreamParser::parserVideoObjectLayer(): this appears to be a
'short video header which we current don't support 

MPEG4VideoStreamParser::analyzeVOLHeader(): marker_bit 2 not set!  

 I am sure I did  not enable short video header flag in my mpeg-4
encoding. I do not why I got these warning messages.   

 my input stream contains one channel of video and the format are 

 Headers +  Elementary_Stream   + Headers +  Elementary_Stream  +
Headers +  Elementary_Stream + .......

 Headers =  Visual_object_Sequence_Header    Visual_Object_Header
Visual_Object_Layer_Header   

I also tried that only sending headers at the beginning,  then loading
Elementary_Stream to streamer without headers between
Elementary_Streams,  but it seemed the streaming was not working at all.


Thank you for your help.
