Alexandra Hájková	f7ec7f546f	wma: Convert to the new bitstream reader	8 years ago
Andreas Cadhalpun	e8651f51aa	wmavoice: validate block alignment This prevents a division by zero crash in wmavoice_decode_packet. The problem was introduced by commit `3deb4b54a2`. Reviewed-by: Ronald S. Bultje <rsbultje@gmail.com> Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com>	8 years ago
Andreas Cadhalpun	91e6a64d2e	wmavoice: truncate spillover_nbits if too large This fixes triggering the av_assert0(ret <= tmp.size). The problem was reintroduced by commit `7b27dd5c16` and originally fixed by `2a4700a4f0`. Reviewed-by: Ronald S.

Ronald S. Bultje	33d7f822f8	wmavoice: protect against zero-energy in adaptive gain control. Otherwise the scale factor becomes NaN, resulting in corrupt output. Fixes #5426.	8 years ago
Ronald S. Bultje	7b27dd5c16	wmavoice: move overflow handling to common code.	8 years ago
Ronald S. Bultje	b011bb5f8b	wmavoice: reindent.	8 years ago
Ronald S. Bultje	3deb4b54a2	wmavoice: disable bitstream checking. The checked bitstream reader does that already. To allow parsing of superframes split over a packet boundary, we always decode the last superframe in each packet at the start of the next packet, even if theoretically we could have decoded it. The last superframe in the last packet is decoded using AV_CODEC_CAP_DELAY.	8 years ago

Ronald S. Bultje	8cfbbd928c	get_bits: introduce safe bitreading to prevent overreads. When turned on, H264/CAVLC gets ~15% (CVPCMNL1_SVA_C.264) slower for ultra-high-bitrate files, or ~2.5% (CVFI1_SVA_C.264) for lower-bitrate files. Other codecs are affected to a lesser extent because they are less optimized; e.g., VC-1 slows down by less than 1% (all on x86). The patch generated 3 extra instructions (cmp, cmovae and mov) per call to get_bits(). The performance penalty on ARM is within the error margin for most files, up to 4% in extreme cases such as CVPCMNL1_SVA_C.264. Based on work (for GCI) by Aneesh Dogra <lionaneesh@gmail.com>, and inspired by patch in Chromium by Chris Evans <cevans@chromium.org>.	13 years ago
