Mar 13, 2013 Part of their cost cutting measures included not purchasing a pricey blanket license to use the MPEG-2 and VC-1 video codecs. This doesn’t mean the Raspberry Pi is not capable of decoding media encoded in MPEG-2 or VC-1, but that by default the codecs cannot run on the Raspberry Pi hardware for want of a proper license.

Applying it to a4.14.44
start.elf
(latest as of time of writing) results in the following diff:Some initial analysis was done by q3kon Hacker News:
Yes, it seems to patch a licensing function at 0xEC95FD4 [1] to always return 1,by patching the jump at 0xEC95FE2 (that should be only taken for the always-allowed H263 codec)to always be taken, thus always allowing all codecs.

After loading and analyzing
start.elf
, we can find the is_licensed
routineat address 0xEC96290
by jumping to the file offset given to us by xxd
beforehand. The relevant code sections are available insub_EC96290.asm and is_licensed.asm.Here, two memory locations (
0xEE86680
for MPEG-2 and 0xEE869E0
for VC-1)that point to the .bss
segment are checked to determine the return value ofis_licensed
. There are no other obvious references to these locations instart.elf
, so memory-breakpoint debugging (TBD) is probably needed.
