Comment (by misty):
I noticed that the original patch in this ticket fails on parsing MPS
files, which is a related format also used on the PSP. MPS files are MPEG
files used on PSP Video discs. They lack the PSMF header used by .pms
files, and so the special casing in the original patch fails to support
their audio. I've attached a patch that fixes this by unconditionally
reading a new byte for the `startcode` for `PRIVATE_STREAM_1` sections,
and doing the comparison on that to find ATRAC-3 streams. In my testing,
it works fine for both MPS and PSMF files.
Is there anything else that devs would like to see before these patches
can be accepted?
