Description

I'm having an issue with ATSC 1080i input and A/V sync. 720p input from the same ATSC source works fine. I can run xinelibout and streamdev clients and the video looks fine - no errors and no jumping. Sat input of SD and HD work fine.

Constant running errors in the log file:

I had a similar issue with SD broadcasts and by changing the Makefile switch below I was able to get it to stay in sync but this does not work with the ATSC input.
CONFIG += -DUSE_MPEG_COMPLETE # support only complete mpeg packets

I have a piece of recorded video available should you want it.

1-2min recording would help, finding the failure.

Where can I upload the file? It's about 253Mb compressed.

Your last update (I just did a pull) seems to have stopped the a/v sync issues! The log file does get filled with messages though.
