The program is copy-protected and tied to the serial, and I don't have the source code.

For example, suppose a C program is using /proc/cpuinfo file to verify the serial number. My bad.ДЄs far as userspace programs are concerned, it's pretty easy to fool them and fake the contents of just about any file. Your stealing' instead of answering the question. Also apologies to the asker, we all just gave you a 'Why? Thats not nice. I honestly doubt that it was actually changed (on the CPU I mean), more like he changed some of the firmware code to return a different serial. I'd imagine that he is really just changing the source code that reads the serial and forcing it to return a different value. I'd say that as Dom has the source for the actual low level firmware.

Your unique serial is linked to the MP4 licence, so even if someone got your licence key, they will be unable to do anything with it (unless they could change the Raspberry Pi's serial number.

As that is the security around the licensing. The only reason for changing the serial would be to copy someone else's MP4 licence and use it.

And releasing any information to allow you to change the serial number would break the mechanism for codec licencing, so will never happen.ДЄdditionally as posted in the thread.

This enables you to swap the same SD card between the different Pis without having to edit config.txt each time. If you have multiple Raspberry Pis and you've bought a codec licence for each of them, you can list up to eight licence keys in a single config.txt, for example decode_MPG2=0x12345678,0xabcdabcd,0x87654321. decode_WVC1Дecode_WVC1 is a licence key to allow hardware VC-1 decoding, e.g. decode_MPG2Дecode_MPG2 is a licence key to allow hardware MPEG-2 decoding, e.g. Therefore, a hardware codec licence key is not needed if you're using a Pi 4.

On the Raspberry Pi 4, the hardware codecs for MPEG2 or VC1 are permanently disabled and cannot be enabled even with a licence key on the Pi 4, thanks to its increased processing power compared to earlier models, MPEG2 and VC1 can be decoded in software via applications such as VLC. Hardware decoding of additional codecs on the Pi 3 and earlier models can be enabled by purchasing a licence that is locked to the CPU serial number of your Raspberry Pi. Or seen, anything with mpeg2 or vc1 file. Stories Discover Categories Issuu Store Features Sign up.ДЄ raspberry-drone projekt: Problems regarding the PWM control of brushless motors. Thank you for purchasing codec license keys from the Raspberry Pi Store.To enable codecs on your device(s), add the following lines to the config.txt file in the FAT partition of your SD card: decode_MPG2=0x40312213 decode_WVC1=0x1f2e3d4c If you want to verify that the codecs are now enabled, the following commands will report their status.
