RTSP parsing error if the RTSP packets are received several TCP block #86

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I had already see that before but it seems to me it was fixed (I didn't re-
find the corresponding mail)

I used the r1650

And in the unimrcpserver.log I can read :

Hi Anthony,

I made a few changes in the trunk to handle TCP segmentation for RTSP and MRCP2
streams from one, common place and this caused the issue to show up again.
Fixed in r1657.

Thanks,
Arsen

There is always an issue if the "START-LINE" is truncated

Accepted! Also, I noticed one more weird issue later yesterday. So, I'll try to 
fix
them as soon as get a couple of minutes. 
Thanks.

Hi Arsen,

Another case : The request is truncated between the CR and LF

Hi Anthony,

Thanks for the help testing this stuff over again. Should be fixed in r1668.
