[patch] add a simple cache to GetSampleCttsIndex() #76

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
My application was spending 70% of it's time reading offsets in this function, 
this patch add a way to cache it similar to the one in GetSampleTimes().

Looks nice, I'll see if I can get this in this week--do you have a piece of 
code I can use to test this change?

Thanks.

No, but I guess a simple app that just reads a video track (h.264 with 
b-frames) using MP4ReadSample() would show the difference.

Sorry for the delay, been really busy.  Patch is in r440.

I saw in subler there was some patch for utf16 support in chapter titles?  If 
you can get me a patch, I can look into getting that into the library.  
Otherwise, no worries.

Those patches are more like ugly hacks. Better if you don't see them. :)
