Add ability to determine recording frame number about picamera

[martinohanlon]

That was quick Dave... I only noticed you had made the change when I
logged into github to fork the picamera repo to make the change myself.

Other data people might find useful to pull out while the video is being
recorded is the ptc and dtc.

Thanks again

Mart

Hi Martin - yup, it was a really trivial change so I figured I'd knock it off and push it to the repo quickly. I'll add some recipes to the docs for it at some point (I'm intending to do three for the split_recording: time-based, size-based, and now frame-based).

What are PTC and DTC? I tried googling a bit for them but drew a blank (the entries on wikipedia's acronyms pages didn't look too promising either).

Ah ha! Did you mean pts and dts as mentioned in this thread? If so, assuming James returns with good news (i.e. that the GPU actually fills in those fields), it should be pretty trivial to extend picamera to support them. I'll keep an eye on the thread and see what James reports. If it's affirmative, I'll open a new enhancement ticket for it.

Yes. Pts, dts. Sorry.

I made some mods to raspivid to pull them out; as I remember it was as
simple as pulling them out of the headers in the buffer.
