Just on a quick look at this log, there appear to be 4 chunks of video stream:
16:38:02 - good timestamps
16:38:35 - good timestamps
16:38:53 - good timestamps
16:39:06 - bad timestamps
Can you confirm this log shows 4 different channels, and only the fourth one stuttered?
The first 3 blocks have timeststamps like:

i.e. the dts and pts values are all valid.
The last one looks like:

The pts:-4503599627370496 means unknown, and most frames have that.
I'm making the assumption that it is just streams with the large numbers of unknown pts values that are not smooth. Is that right?
