I haven't read the whole thread, but are there any chances that some of you can achieve some video improvements on the K-3 like changing the codec or upping the bitrate?
Not now!

pentax firmware is encrypted, one has to decrypt, the suggested software is frmcrypt.exe the inbuilt en/decryption is cipher, working of cipher are available (this is a command line programme), thus after pasting the frmcrypt.exe in sys32 running as command line lands as attached, which means nothing or am i wrong. frmcrypt itself is encrypted, looks more of a Pentax software, one can open it in either ida pro, notepad++, hex editor neo to see the sate its in (thought irrelevant to run if procedure is stated, and guess its with pentax) end of road

I do believe that the majority of people who are waiting for this hack are waiting for it because they hope to improve Video codec like either change bit rate to a more broadcast level capturing or entirely swap the codec.

Hopefully wonderful guys who work on this will succeed

So you think there is a chance it will be done in future?

your post makes no sense - we're long past the point of decrypting pentax firmware and i linked you to the open source tool i wrote that does just that.

The error report suggest, it's 32-bit software on 64-bit system and behaving bad.

I haven't catch the idea why you want to use frmcrypt in stead of pfwtool. Try pfwtool and if it doesn't work like it should, help to make it work. If I'm correct frmcrypt is propietary code from rather untrusted source.

ptxfwtool.c tool

svenpeter:Thank you very much for source of your tool ! Finally I was able to deobfuscate and disassemble K-5 firmware. Thank you again!Note for people compiling source on Windows. You should change following lines:
Code:
fp = fopen(path, "r");
...
FILE *fp = fopen(argv[2], "w");
to:
Code:
fp = fopen(path, "rb");
...
FILE *fp = fopen(argv[2], "wb");
Otherwise tool is not working correctly.
