Thank you Vitaliy and your team for your awesome, awesome work. Next paycheck I'll make sure to send more money your way.
A question for you hackers: from what you have written, it seems like the sensor can output both 25fps and 30fps depending on NTCS/PAL settings. Does this mean that the sensor's framerate can be set via firmware? What about 60p? Is that actually possible?
In anycase, looking forward to your hack.
Thank you again, J.
Yep, bitrate is set at 10Mbit, but bit_rate_value_minus1 and cpb_size_value_minus1 do not match. Same for 1080 MP4 modes (as they are more approariate for 22-23Mbit.).
Bitrate readings - Stock Settings PAL 25p MP4
Yep, if you look, they are higher than 1080p24 settings (with formally higher bitrate) :-)
Even more difference is in 720p MP4, as they are higher than settings for 16Mbit modes :-)
I absolutely do not get why this 10Mbit is used.

MPEG-4, Advanced Video Coding, Baseline Profile Description:
Baseline is the least complex of the three original MPEG-4_AVC profiles (Baseline, Main, and Extended), i.e., it places the least demand on a decoder. The Baseline Profile is constrained in several ways, including a limit to intra (I) and predicted (P) slice types (slice is the MPEG-4_AVC term for a single macroblock or a set of macroblocks that make up a portion of an individual picture.) For a discussion of additional contraints and the levels that may be used in this profile, see Appendix A in Part 10 of the standard, pp. 204-211.

Thanks guys.
GX1 is complicated. Due to MP4 and some changed code.
That a very welcoming ptools picture @Vitaliy_Kiselev :-) Congrats on your hard work.
PTool, work in progress.
Various MP4 specific modes settings are being added.
Take care VK. Hope you soon ok again.
Take care. Priority to health, family and friends. ptool can wait :-)
