No problem, I can explain EVA format (I examined it some time ago).
1- EVA files 10fps:
- Each frame takes 30 sectors (15Kb)
- First 128x106 bytes are YJK data
- Rest of bytes are PCM data
- Last two bytes indicates PCM size (they should be 1575 =15.75k/10fps)
2- EVA files 12 fps (this one uses a 'dirty' system):
- Each frame takes 30 sectors too
- Data is stored in this way:
[{PCM(1byte)+PIC(11bytes)}*11+PCM(1)+PIC(7)]*106 lines
- Rest of bytes are PCM data
- Last two bytes indicate the same (they should be 1312 or 1313=15.75/12fps)
I hope you to find this info useful.
Bye,
Manuel
