FFmpeg RTSP problem with IP camera

I download FFmpeg windows binary and use ffplay.exe successfully for media files and some Ip Cameras with RTSP support (eg Acti).

I try ffplay on a Bosch( h264) NDC 265 P camera it does not work. When i start ffplay with debug option i get folllowing 

D:\Test>ffplay -debug 1 rtsp:/XXXXXXXXXX/video

Got the same issue with H.264 stream from Bosch DINION HD camera on attempt to play it with ffplay (version 0.10).

The root cause of your problem is in the incorrect payload type in SDP:

m=video 0 RTP/AVP 35
a=rtpmap:35 H264/90000

Looks like that's common case for Bosch devices to send out their data on pt value 35 instead of the normal dynamic range.
Just remove the pt in the h264/mpeg4 and h263 (de)payloaders and you will have support for Bosch.

As well several related issues for this problem:

Same was found for set of another Bosch devices: Bosch DINION HD 720p IVA, Bosch DINION NBN-498-P IVA, Bosch NTC-255-PI, Bosch VIP X1600 XFM4.
