I'm currently decoding H264 frames with the microsoft decoder and then rendering it to the screen. It works fine for a few seconds and then goes into a weird loop where it shows a set of previous old samples and then a newer one. It continuously loops through these same 2 sets only updating the second one to a somewhat newer series of samples. I have the decoder set to low latency mode but even turning that off doesn't change anything.
Here is a portion of the end of my mftrace log:

I can see that at a certain point the decoder is unable to process the data until it fills up a buffer of 499ms worth of samples but I don't understand why. I'm so confused as to why this isn't working. Especially why it's displaying samples from
so long ago but, I don't see any indication of using those samples in the trace. Any help would be greatly appreciated. I'm desperate to find out why this is happening.
