"glitch" can mean lots of things, and a decoding failure is only one of them 
and better to call it what it is (i.e head-switching noise from an analog 
source can also be called a glitch, as could a dropped frame).

In this case, it looks like a transmission/data error or dropped packet(s). 
Can a frame-based filter even look for that? You're kind of getting into 
Automatic Content Recognition, which gets tricky and isn't a job for the 
command line utils.

There is a freezedetect filter, but that may not be what you want.

I think you better off looking at the log messages for decoder errors.
