Ronald S. Bultje 0399fe0fd2 lzw: fix potential integer overflow. 2012-03-29 11:36:14 -07:00
Ronald S. Bultje b7b1509d06 truemotion: forbid invalid VLC bitsizes and token values.
SHOW_UBITS() is only defined up to n_bits is 25, therefore forbid
values larger than this in get_vlc2() (max_bits). tokens[][] can be
used as an index in deltas[], which has a size of 64, so ensure the
values are smaller than that.

This prevents crashes on corrupt bitstreams.

Martin Storsjö 9bd41bb191 configure: Check for a different SDL function
This one is available both in SDL 1.2 and in 1.3 (which is the current
version available e.g. in macports), while 1.3 doesn't contain
SDL_Linked_Version().

The current check for SDL_Linked_Version() (available since SDL 1.2.13)
was added in 8f1b06c8, because including the headers for SDL_Init()
redirects the main() function, requiring the main function signature
to match the one of SDL_main (including argc/argv).

Kostya Shishkov a05c41acd1 mp3dec: perform I/S and M/S only when frame mode is joint stereo.
Looks like some LAME versions produce dual stereo mode MP3s with
flags for intensity and middle stereo set. In this mode those flags
should be ignored like the reference decoder and derived ones do.

Mashiat Sarker Shakkhar 28e8c4d59a WMAL: Remove inaccurate and unnecessary doxy
A call to decode_packet() does not always decode a complete WMA packet.
Moreover, this is not the correct place to document calls that are part
of the public API.

Ronald S. Bultje 44257ef426 asf: only set index_read if the index contained entries.
This allows falling back to a binary search if the file contains no
index, thus fixing seeking in such files (e.g. luckynight.wma).

Mans Rullgard 2efb710a34 build: fix doc generation errors in parallel builds
The $(dir) function used to construct OBJDIRS includes a trailing slash
in the names returned, which GNU make 3.82 does not match to the
slash-less 'doc' in the documentation dependencies, causing parallel
build to fail.  Adding a slash fixes this and still works with make
3.81.

Ronald S. Bultje 5484170ac7 rv34: set mb_num_left to 0 after finishing a frame
Prevents running error resilience on a previous frame which will write
to the pic->mb_type[] array of the previous image. The array might
already be re-used for a new image in a subsequent thread, thus cause
two threads to write to the same pic->mb_type[] array, causing a race
condition which can crash in rv34_decode_cbp(), called by
rv34_decode_inter_mb_header() (which accesses mb_type[] twice,
assuming values are maintained, which the race condition breaks).
