Seeking doesn't work well in M4A files with very few chunks due to
the seek method used (chunk based using the info in the 'stco' atom).
According to libm4a/demux.c the expected seek resolution using this
method is 1/4 to 1/2 seconds. However, ffmpeg generates files with a
1 megabyte chunk size, so the resolution is much worse than expected
on some files: around 30-40 seconds at 256kbps.
There was a bug with the seek position reported back to Rockbox: the
codec pretended it could seek exactly to the requested sample, but it
would only seek to the start of a chunk. This could leave the UI in a
confusing state because the real playback position was different from
what the elapsed time showed. Fix this by recalculating the reported
sample position using the chunk start.
To fix the low seek accuracy, use the table in the 'stsz' atom to skip
individual packets within a chunk. This is very accurate, but it takes
a lot of RAM to allocate the table. Currently the table is not allowed
to use more than half of the codec RAM, which should suffice for short
files on most targets. On files where the table is too large the codec
will fall back to the less accurate chunk-based seek method.

It was possible for the tag tree's buflib move callback to turn a
null pointer non-null. The tagcache_search_clause->str can be null
for OR clauses. Also ensure that clauses are zeroed on allocation
to ensure garbage pointers don't creep in.

A couple of places use sizeof(int) for allocations and copying but
the indices are longs, which causes bugs in the simulator on 64-bit.

UBSan reports an avalanche of unaligned pointer bugs stemming from
hardcoded 4-byte alignments used in certain places. Use sizeof(long)

These operations can only be used in limited circumstances and have
exactly one user. bufgettail especially seems of dubious value; how
often do you need to read N bytes from the end of a file without
changing the file position?
strip_tags() was the only function using them, to strip off ID3v1
and APE tags off the end of buffered tracks. This would save only
32-192 bytes per track -- if the container format uses APE/ID3v1.
It hardly seems worth the effort.

According to the on screen instructions, any other button
should mean No.
More importantly, in my experience at least, the Select
"button", since it is touch-activated, can sometimes be
pressed by accident, especially when a warning screen
is displayed as a result of pressing that same button.

np_file is a buffer of size MAX_PATH. After
removing only the file name component and
leaving the rest of the path, the
available space may not be sufficient
for appending another file name (possibly of
size MAX_PATH itself) to it.
This can occur after a file of acceptable
length is opened in ImageViewer, and you
then advance to another file whose path
(including the file name) is longer than
MAX_PATH.

This plugin provides a menu for easily editing the root redirect file
on targets that support multiboot. You can select a new root from a
list of Rockbox installations detected on the filesystem or remove all
redirects to boot from the default location.
To avoid searching the whole filesystem, only subdirectories of the
volume roots are checked for valid installations. Only installations
that are compatible with the current player will be displayed.

Reworking handling of player specific data (static player configuration,
as well as information retrieved from the server) changed the behaviour
on a non-present configuration entry. This eventually caused the
mountpoint not being set for players that don't have a bootloader file
on disk. Fixing this accidentially removed the default-if-not-found
handling for the bootloader file.
Restore the old default value behaviour for both cases.
