Description
Summary of the bug: When generating a mpeg transport stream file with streamid 0:0x11 cur_dts gets invalid which results in invalid macro blocks for every P and I Frame.
How to reproduce:
% ffmpeg -i input -codec libx264 -streamid 0:0x11 output.ts ffmpeg version 20180518-8e7b13b nightly build downloaded from https://ffmpeg.zeranoe.com/builds/
Any other streamid works fine. The -r Flag doesn't resolve the issue.
Attached is the output log generated via report flag.
Patches should be submitted to the ffmpeg-devel mailing list and not this bug tracker.

PID 0x11 is one of the PIDs reserved for DVB metadata; it's generally a bad idea to use this PID for any real stream, because it can be confused with said metadata.

I know. I came recently to the team working on said problem... there is no way to change it.
I would be really grateful for a hint where i should look in the code.
