My discussion of pts/dts and time_base.den surrounded the common 
AVCodecContext, which should be relevant to ffmpeg muxing in general.

Yes, but these are facilitated through a common code layer. Quite frankly, it 
is hard to tell where common behavior and muxer-specific behavior starts / 
ends. I threw it out in hopes of shedding light on something that might be 
affecting your situation, as it sounded like it had some similarities to things 
which I had encountered. FFmpeg development in general has been an exercise of 
frequently wandering around in the dark, and I personally appreciate those who 
take the time to offer ideas and things they've run into, even if not identical 
to my use case, as they may shed light on possibilities in my situation, and 
the knowledge can be applied and yield some progress. 

My apologies, though I wouldn't have known anyway -- I was not aware that 
pts/dts and time_base.den were handled differently across muxers. I guess I 
missed that part in the ffmpeg user guide. I guess it also means Dranger's 
discussion of them would be not generally applicable either, as I don't recall 
his information being muxer-specific. Good to know. 

Nevertheless, I hope you get your problem solved. I'll keep my powder dry on 
throwing out possibly relevant info anymore in this thread. 

Good luck, 

Brad
