Apple Iphone 5 sample about ccextractor HOT 2 CLOSED

I'll be looking into this specific file later, but for now some references:

https://developer.apple.com/library/mac/documentation/quicktime/qtff/qtffchap3/qtff3.html

The file seems to be having a lot of those CC "atoms", which further contain the actual CC data. Task here will be to figure out how those "atoms" are structured and then try to get the actual CC data joined together so that it can be read out correctly.

from ccextractor.

Reading the atoms should be easy, since the MP4 library we use is quite
good... Just check the MP4 main loop and you'll see.

I've I remember correct what we do here is just read the H264 NALs (looking
for the one with data) and dispatch the data to the AVC code.

We could easily check if there's one of these specials CC atoms and just
read it with an alternate loop.
