How might I start digging into the code at this point and seeing what's going on? I'm not certain if looking at the files mentioned are the best place to start as I'm guessing they are responding to something going wrong somewhere else.

I am wondering if you’re seeing the same freeze that I am.

Are you using omxvideoenc or omxvideodec? I am seeing a freeze when omxvideodec receives an out-of-order packet from an rtp source, I get "no valid PTS, using oldest DTS” from videodecoder followed by "decreasing timestamp”. Do you see anything like that your side?

I also stumbled on this freeze being reported from (what I believe is) the same GPU hardware that’s in the PI, not had a chance to work out if this is related:
