This overrides the normal content/extension detection, but can be overridden
by the user.
This is an input plugin API extension; ABI is unchanged.
The version is not bumped (we can't bump it due to 1.2).

All the initialisation functions returning a new object instance that
was allocated through malloc() or calloc() can get the malloc
attribute so that the compiler can optimise their call.
|
|
The new structure xine_current_frame_data_t additionally contains cropping
and interlacing information, which both are required for proper conversion
of the image. The existing functions have been adopted to use the code of
the new function. The changeset should be ABI compatible.

Also don't reset memory after it's allocated if we do that with
calloc.
|
|
Using asprintf() instead of malloc() + sprintf() reduces the lines of
code in xine-lib (moving the allocation to the C library or asprintf
replacement), makes it safer to access the string and can also improve
performance whenever the value returned by a function was used as
parameter, as before it had to run the function twice in almost every
case (once for strlen(), once for sprintf()).

|
|
The xine_xmalloc() function is going to be deprecated, as its
behaviour is rarely needed as such, and it's thus misused.
With this, almost all uses of xine_xmalloc() with static size (for
instance the value returned by sizeof()) or with a size that is
guaranteed not to be zero (like strlen()+1) are replaced with calls to
either calloc(1, ...) or malloc().
malloc() is used whenever the allocated memory is going to be
immediately overwritten, while calloc() is used in every other case,
as it sets the whole memory area to zero.

Functions and data structures that are not exported and are only ever
used in the same unit they are defined should be marked static to
improve compiler's ability to optimise them.
This applies to xine_dispose_internal() function for xine-lib, the
extended_to_int() function in the AIFF demuxer, the bandwidths array
in QuickTime demuxer, the wc_pal_lookup table in the WC3 movie
demuxer, and the rm_header and pnm_data_header arrays in pnm input
plugin.

The problem comes from the fact that into xine_probe_fast_memcpy() there is
a call to xprintf, which excutes some actions to this->log_lock. But the
"log_lock" field is still uninitialized. Under Windows, the xine_init()
always crashes because that type is implemented as a structure, so the lock
receives a NULL pointer and the execution is halted. The attached patch
proposes to move the mutex objects to the top of xine_init() function.

With Pthreads for Win32/Win64 I cannot compare two pthread_t items because
they are implemented as structures. This patch fixes the comparison by
using pthread_equal() function.

Changeset 8ffe18290ba5 fixed bug 1784272 (opening raw filenames with #
character, like "show #1.mpg") but at the cost of killing # separator in raw
filenames completely. Although this might be a valid requirement in a new devel
branch, imho, such change in stable branch should be considered a regression.
The original idea of passing partial MRL for the input plugins to try doesn't
work because plugin will generate error messages for every failed attempt to
open the file (like "show " above), even thought the complete MRL is valid
and will be played.
So, since raw filenames are an exception for the MRL scheme anyway, we
try stat'ing the partial filenames to determine what user means with the #.

Retrieving frame size and format is a legal operation even for
otherwise not supported frame formats like XXMC.
|
|
xine_get_current_frame() relies on the caller to provide a sufficiently
sized buffer. To calculate the required size of the buffer, one has to
call xine_get_current_frame() to retrieve the necessary parameters. But
as the image can change between two successive calls one has to pause
the stream for consistency.
To improve the situation, xine_get_current_frame_s() has been introduced
which requires to specify the buffer size when an image is going to be
retrieved. Furthermore, it will return the required/used buffer size.
In that way, it can prevent copying data into a too small buffer and
therefore can be considered safe.
For convenience, xine_get_current_frame_alloc() is provided which takes
care to allocate a sufficiently sized buffer. This function avoids
pausing the stream as the image will be returned in a single call.

This has a side effect: versions older than 1.1.10 do not unescape, so
"#save:foo%23.ts" will result in a file named "foo%23.ts".
Front end maintainers, beware :-)

It changes some "defined (__FreeBSD__)" into "defined (__FreeBSD_kernel__)"
and "__FreeBSD_version" into "__FreeBSD_kernel_version".
The changes are performed on places, where feature of kernel is tested. On
some other places, feature of userland/libc is tested, on them "defined
(__FreeBSD__)" remains.
As proposed, include/configure.h cause __FreeBSD_kernel__ be defined if
__FreeBSD__ is defined.

According to bug 1773769, this breaks foo->open().
The fix (as used in Ville Skyttä's patch, which doesn't cover all cases) is
to replace this with (foo->open)().
This patch was generated using
sed -i -re 's/(([[:alnum:]_]+(->|\.))+open) ?\(/(\1) (/' `grep '[>.]open \?(' include -rIl`

When using DVB subtitles on an SMP machine, we see occasional lockups, which
appear to be caused by one thread acquiring the same ticket twice. Fix this,
by preventing acquire() and release() from blocking if the current thread has
already acquired the ticket.
Code sequences like the following can still block in all acquires and
releases:
ticket->acquire(...)
/* Do something */
ticket->release(...)
However, code sequences like the following, which used to deadlock if ticket
was revoked at just the wrong moment, now succeed:
ticket->acquire(...)
/* Do something */
ticket->acquire(...) /* This acquire cannot block */
/* Do something */
ticket->release(...) /* This release cannot block */
/* Do something */
ticket->release(...)
Without this patch, the inner acquire() and release() calls could block if
ticket was revoked at the wrong time. revoke() would not unblock the blocking
acquire until there have been as many release()s as acquire()s, which cannot
happen.

This function shall be used to poll the number of remaining frames
from a certain point in time on until the reported numbers are all
0. At that point in time, the content on screen is identical to a
certain state of the stream, at which for example, a hardcopy may
be taken.
|
|
The current code has a race condition which can block arbitrary
threads that call for example xine_get_current_frame() until the
stream gets unpaused again. This can happen when the internal
ticket acquiration collides with a ticket revokation for example
when another thread is going to pause the stream.
There are a few situations where a port ticket needs to be
acquired for calling a port function but where it is absolutely
undesireable to get blocked for an undetermined period of time.
Therefore the ticket system should be extended by nonblocking
functions which allow ticket acquiration even when a ticket
revokation is in progress. And in the case where blocking is
not avoidable, it should simply be indicated that no ticket was
acquired. The caller can then choose to repeat the call at a
later point in time.
