Mans Rullgard	da4c7cce21	x86: fix build with gcc 4.7 The upcoming gcc 4.7 has more advanced constant propagation resulting some inline asm operands becoming constants and thus emitted as literals, sometimes in contexts where this results in invalid instructions. This patch changes the constraints of the relevant operands to "rm" thus forcing a valid type. While obviously suboptimal, this is what older gcc versions already did, and there is no change to the code generated with these. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Mans Rullgard	b4cfb8254e	dnxhddec: avoid a branch in 10-bit decode_dct_block() The minimum weight value is 32 so this test can be skipped for the 10-bit case. Overall speedup 3-4%. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Mans Rullgard	5cc2600964	dsputil: create 16/32-bit dctcoef versions of some functions High bitdepth H.264 needs 32-bit transform coefficients, whereas dnxhd does not. This creates a conflict with the templated functions operating on DCTELEM data. This patch adds a field allowing the caller to choose the element size in dsputil_init() and adds the required functions. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Ronald S. Bultje	80469eafb7	mpegvideo: fix invalid picture unreferencing. Mpegvideo would free frames as soon as they're not the next or prev picture. This is fine for a single-threading model, but fails miserably in a system where pictures can be referenced (as e.g. last/prev pic) in other threads. Keeping track of ownership of pictures keeps image references (e.g. motion vectors, or the reference of a motion vector) alive as long as the picture data itself is alive. This also happens to fix make THREADS=[3-16] fate-vsynth[12]-error.	14 years ago

Justin Ruggles	08a747afb9	eac3enc: use frame exponent strategy when applicable. This checks if the set of selected exponent strategies for all blocks in a channel are in the frame exponent strategy table, and if so, writes the table index instead of each strategy. This saves up to 7 bits per channel per frame, so the overall effect on quality is small.	14 years ago
