S5IS video bitrate/compression

Hello all,

Please excuse me if this has already been asked, but does anyone know if the VIDEO BITRATE/COMPRESSION will be added to the S5IS?


Thanks, the Alchemist.....

 It is not very difficult to implement.

I don't have time to do that right now :p I'll have to see if the video code is comparable first but I fear the worst. It's on my todo list.

 Don't fear,its just a boring and time-consuming but task if you're determined. To get the full xref tree,don't trust
 IDA's 'XREFs TO' command. Instead copy the IDB in some text editor(a huge file). Start from Task_MovieRecord.
 Now find the occurrences of this task just by simple text search,identify those functions and repeat this procedure
 for those functions (thus do it recursively) until everything converges to task_Startup or some 'important' function
 before that which has been already hooked via boot.c. 
 Now add some more functions which emerge from task_MovieRecord,these are responsible for bitrate changing.
 The real trouble is that S5IS has more functions related to movie mode than the A-series and that will make the job
 more time consuming. But in theory,it can be done by the above procedure. 

 P.S. Now I think you already knew all that! :)

Thanks guys!

Say DataGhost are you the ONLY programmer working on this stuff?

Eh, someone else can do it, but I guess (not sure :P ) I'm the one with the most S5IS coding experience / knowledge. This task doesn't really require that, but it'd be handy to have a camera around for testing.
