H264 decode on mpeg2 transport stream

Hi All,

I have question regarding h264 dissector in wireshark. I Can see in wireshark preferences that there is some default impelementation of this protocol (H264) so i assume that wireshark should show some NAL packets information in the packet window. Instead of this i have just pes data payload. How can i decode this payload as H264 protocol ? Protocols that is recognized in my stream is 13818-1 MPEG2 transport stream, then paylod is packetized elementary stream and the payload of the PES should be H264. This is not decoded by wireshark.

Please help. Thanks.

Br,
