when you record a video on your original SGS 4G camera, your audio sampling is :
66 kbps bit rate.
16 KHz sample rate.
which is pretty lame...
If you ever tried to record live shows or concerts, you probably noticed audio is awful on recorded video...
Introducing Video Recording audio improvement MOD
found and very well explained by rafalense (http://forum.xda-developers.com/show...&postcount=268).
Performed on SGS 4G camera by me. So, now recorded audio sampling is :
118 kbps bit rate.
32 KHz sample rate.
file size change is barely noticed.
Still camera is not modified.
I took, as a basis, the Team Acid modified camera - done by DSexton702.
So it is capable of taking pictures when battery is low and also by using the power button.
This is still in beta as :
1. Currently Audio-Video is out of sync. I need to check if this can be fixed by changing Video sampling rate....
In the meanwhile, you can fix this on PC very easily.
2. This mod does not use the media profile xml for greater video frame rate.
I actually put the original file back. I found the result to be not supported by all players and having some side effects like visual waves (and much larger file size).
3. Actually I examined DSexton702 media profile and it defines some various audio sample rates but always create 16KHz at the end.
If someone here has the knowledge in A/V synchronization or a good setup that works - please let me know so i will fix it.
