Bug Description
I have a VoIP stream with audio (either G729 or G711) + video in RTP PT=H264.
The H264 stream is compressed but most frames fail to decompress (give error-code -4 or -5).
I proved that the H265 causes rohc failures, by filtering out the video/H264 steam (it is udp-port 5006 which I can sent uncompressed) while I feeding the rohc_compress2 with the rest (i.e. the audio), which make the "call" successful.
I have tried to use it with & without ROHC_PROFILE_RTP, while only using ROHC_PROFILE_UDP, but the problem was there.
I am using ROHC v1.6.1 in x86 Ubuntu-10.4
Attached a pcap file, of the original stream (w/o rohc) stream.

I reproduced the problem. It seems to be related to RTP TS that doesn't change for several packets. I continue the analysis.
