James Almer	72254b19b8	x86/alacdsp: add simd optimized functions Signed-off-by: James Almer <jamrial@gmail.com>	9 years ago
James Almer	b70566d6ca	avcodec/alacdec: split off decorrelate_stereo and append_extra_bits as alacdsp Reviewed-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: James Almer <jamrial@gmail.com>	9 years ago
Ganesh Ajjanagadde	2cbaa078d1	avcodec: use HAVE_THREADS header guards to silence -Wunused-function When compiled with --disable-pthreads, e.g http://fate.ffmpeg.org/report.cgi?time=20150917015044&slot=alpha-debian-qemu-gcc-4.7, a bunch of -Wunused-functions are reported due to missing header guards around threading related functions. This patch should silence such warnings. Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>	9 years ago
Hendrik Leppkes	eb011f73ca	avcodec/alac: remove dead code cruft The output is always planar since two major bumps, remove all code related to packed output.	9 years ago

Michael Niedermayer	f7068bf277	avcodec/alac: Clear pointers in allocate_buffers() Fixes: 06a4edb39ad8a9883175f9bd428334a2_signal_sigsegv_7ffff713351a_706_mov__alac__ALAC_6ch.mov Found-by: Samuel Groß, Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	10 years ago
Andreas Cadhalpun	243e8443cd	alac: Reject rice_limit 0 if compression is used If in compression mode rice_limit = 0 leads to call `show_bits(gb, k)` in `decode_scalar` with k = 0. Request a sample in case it is valid and it should be accepted. Signed-off-by: Luca Barbato <lu_zero@gentoo.org> CC: libav-stable@libav.org	10 years ago
Andreas Cadhalpun	4b657a1b1e	alac: reject rice_limit 0 if compression is used If rice_limit is 0, k can be 0 in decode_scalar, which calls show_bits(gb, k). Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago

Christophe Gisquet	30cac8313a	alac: add option to decoded incorrect ALAC Prior to 56.1.100, incorrect ALAC files for 24bps content were produced, in particular not decoding losslessly. Add an option to allow correctly decoding those streams. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Martin Storsjö	59480abce7	alac: Do bounds checking of lpc_order read from the bitstream In lpc_prediction(), we write up to array element 'lpc_order' in an array allocated to hold 'max_samples_per_frame' elements. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Martin Storsjö	35cbc98b72	alac: Check that the channels fit at the given offset The code tries to decode a number of channels at the offset given by the ff_alac_channel_layout_offsets table. Even if the number of channels decoded so far doesn't exceed the total number of channels, we need to check that we actually can decode that number of channels at this offset as well.

Martin Storsjö	f7c5883126	alac: Limit max_samples_per_frame Otherwise buffer size calculations in allocate_buffers could overflow later, making the code think a large enough buffer actually was allocated.

Justin Ruggles	68a04b0cce	alacdec: do not be too strict about the extradata size Sometimes the extradata has duplicate atoms, but that shouldn't prevent decoding. Just ensure that it is at least 36 bytes as a sanity check. CC: libav-stable@libav.org	12 years ago
