I added 24 bit support a while ago, but it wasn't possible to force 24
bit output. Add 24 and 8 bit to the list of allowed sample sizes.
Although 8 bit audio isn't as widely used as 24 bit, there is no
reason to exclude it.
|
|
Splitting a frame between two buffer chunks causes distortion in the
output. MPD used to assume that the chunk size 1020 would never cause
splitted frames, but that isn't the case for 24 bit stereo (127.5
frames), and even less for files with even more channels.
|
|
Don't attempt to map paths which are already absolute with
map_song_fs(): check with song_in_database() instead of
song_is_file().
|
|
The "rm" command did not send notifications to idle clients. Add it.
|
|
The function deletePlaylist() shouldn't be in playlist.c.
|
|
Don't use our deprecated linked list library, use GLib's GPtrArray
instead.
|
|
The "long" result of strtol() was implicitly casted down to a 32 bit
integer. Add some range checking instead.
|
|
Many command arguments must not be negative; add a separate
parser/checker function for that. For the same reason, add
check_bool(). This eliminates two strange special cases handlers from
check_int().
|
|
Pass index arguments as unsigned integers. They must not be negative,
and even if some caller accidently passes -1, it won't pass the bound
checks (since it's now 2**32-1).
|
|
There are some integers which have a "magic" -1 value which means
"undefined" or "nothing". All others can be converted to unsigned,
since they must not contain a negative number.
|
|
Instead of returning 0 for success and -1 for failure, return true or
false. This seems more natural.
|
|
Also add names for "error" and "ok". I don't like passing anonymous
integer codes around.
This is not yet complete: lots of functions (e.g. in playlist.c)
follow the same convention of -1/0, and these have to be adapted, too.

|
Eliminate CamelCase in all public and static functions.
|
|
The typedef CommandHandlerFunction is only used once. Move its type
into the command struct.
|
|
|
|
Send last modification timestamps to the client. This allows the
client to see when another client modifies a stored playlist.
|
|
"listplaylists" returns a list of all stored playlists. This command
seems more elaborate than listing them below "lsinfo".
|
|
The function print_spl_list() replaces the old function lsPlaylists()
from ls.c.
|
|
spl_list() provides an interface for enumerating all stored playlists.
This separates the internal playlist logic from the protocol specific
function lsPlaylists().
|
|
The return value of spl_append_uri() was somewhat buggy: some branches
returned ACK_* values, and some an enum playlist_result. Unify this.
|
|
Rename addToStoredPlaylist() to spl_append_uri(), and remove the
clearStoredPlaylist() macro.
|
|
The two functions clearStoredPlaylist() and addToStoredPlaylist()
don't belong into playlist.c. clearStoredPlaylist() was a wrapper for
spl_clear(), and is converted into a CPP macro for now.
|
|
Renamed all public functions, prefix is "spl_".
|
|
No CamelCase in file names.
|
|
The list of commands is known at compile time. Instead of creating a
linked list on startup, we can just register all commands in a static
sorted array.
|
|
The command pointers which are passed around aren't being modified -
in fact, no command pointer must be modified once it has been added to
the commandList.
|
|
No CamelCase and no struct typedefs.
|
|
Instead of manually calling memset(0) on the pcm_convert_state struct,
client code should use a library function from pcm_utils.c. This way,
we can change the semantics of the struct easily.
|
|
Renamed all functions which were still in CamelCase.
|
|
No CamelCase, and a struct instead of a typedef.
|
|
Casting a pointer to some sort of integer and formatting it into a
string isn't valid. A pointer derived from this hex string won't work
reliably. Since ffmpeg doesn't provide a nice API for passing our
pointer, we have to think of a different hack: ffmpeg passes the exact
URL pointer to mpdurl_open(), and we can make this string part of a
struct. This reduces the problem to casting the string back to the
struct.
This is still a workaround, but this is "sort of portable", unless the
ffmpeg people start messing with the URL pointer (which would be valid
according to the API definition).
|
|
Since ffmpeg svn r12865, you have to include libavcodec/avcodec.h
instead of avcodec.h. This cannot be checked at compile time, instead
we have to add a check to configure.ac. Viliam's original ffmpeg
plugin was based on the newer ffmpeg library, while my Debian
installation had the older version. My attempt to correct his include
statements wasn't correct after all.

{song,dir}vec_for_each each failed to gracefully handle deleted
files when iterating through. While we were thread-safe, we
were not safe within the calling thread. If a callback we
passed caused sv->nr to shring, our index would still increment;
causing files to stay in the database.
A way to test this is to remove 10 or so contiguous songs from a
>10 song directory.
|
|
Like the songvec nr_lock, only one lock is used for all
traversals since they're rarely changed. This only
projects traversals, but not the individual structures
themselves.
|
|
We definitely don't modify them here.
|
|
This will make it easier to introduce locking
|
|
There was only one user of pathcpy_trunc(), which can be eliminated.
|
|
Again, GLib's version is more robust than ours.
|
|
GLib's g_path_get_basename() is much more reliable than
mpd_basename(). The latter could be tricked into an assertion
failure.
|
|
Identifiers with two leading underscores are reserved for the C
compiler's internal use. Don't use them in the source.
|
|
Due to an off-by-one bug in map_fs_to_utf8(), the function returned
database paths with a leading slash.
|
|
The macro name is HAVE_STRUCT_UCRED, not HAVE_UCRED.
|
|
The typedefs aren't using by anybody but struct input_stream. Remove
them and declare the method type within struct input_stream.
|
|
The mpdurl_* code is internal, don't expose them. Also don't
initialize struct members with NULL.
|
|
client->permission is a bit set, and should be unsigned.
|
|
Reduce two temporary variables to only one.
|
|
There is no sense in using the kernel's send buffer size (SO_SNDBUF)
for MPD's send buffer. Convert it into a static buffer of 4 kB.
|
|
Use a literal in the struct declaration, and sizeof(client->buffer)
everywhere else. Also shrink the buffer from 40 kB to 4 kB. The
buffer must only be large enough to hold one line of input, and 4 kB
is still more than enough.
|
|
The buffer pointers must not exceed the buffer size.
