Found this testing the 1.0 gnonlin plugins from git.

I have 2 video slices of 10 frames each, and am then sending this through the
"identity" element with single-segment=true. The timestamps for the first slice
are correct, but when it gets to the 2nd segment (2nd slice), the buffer.pts is
CLOCK_TIME_NONE for every frame, like this:

0

Here's my test script:

This doesn't appear to be a gnonlin issue because if I use
single-segment=false, the buffers all have the expected pts passed through from
the underlying video:
