Michael Niedermayer	729b2d02af	utvideoenc: align mangled buffer starts. This is essential for fast SIMD accesses. The same should be done with the predict output. Reviewed-by: Derek Buitenhuis <derek.buitenhuis@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Michael Niedermayer	f92f4935ac	utvideoenc: use ff_generate_len() 19% faster smaller files this may also fix possible integer overflows due to previous 32bit useage Tested with libutvideo and our utvideo decoder, this patch does not change decoder output in the test Reviewed-by: Derek Buitenhuis <derek.buitenhuis@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Nicolas George	52820bc578	lavfi/overlay: fix return values. They were only roughly adapted when error return was added to the push functions.	12 years ago

Nicolas George	beeba9161a	lavfi: add a closed field to AVFilerLink. It will help forward errors and maintain consistency.	12 years ago
Nicolas George	ac07f941ae	ffmpeg: use AV_BUFFERSRC_FLAG_PUSH. It reduces the lifespan of buffers in filter graphs, and therefore the memory consumption.	12 years ago
Justin Ruggles	5d4ef004bf	adpcm_swf: Use correct sample offsets when using trellis. Fixes invalid reads when encoding mono streams when trellis is used.	12 years ago
Samuel Pitoiset	7011a42b1a	rtmp: support strict rtmp servers In order to send or receive a stream FCPublish, FCSubscribe and _checkbw are completely optional and often not implemented. releaseStream over a non-existen stream might report an error instead of being silent.

Mans Rullgard	5b170c0bea	x86: remove FASTDIV inline asm GCC 4.3 and later do the right thing with the plain C code. Earlier versions in 32-bit mode generate one extra instruction, needlessly zeroing what would be the high half of the shifted value. At least two gcc configurations miscompile the inline asm in some situations. In 64-bit mode, all gcc versions generate imul r64, r64 followed by shr. On Intel i7 and later, this imul is faster 32-bit mul. On older Intel and all AMD, it is slightly slower. On Atom it is much slower. Considering where the FASTDIV macro is used, any overall negative performance impact of this change should be negligible. If anyone cares, they should file a bug against gcc and get the instruction selection fixed. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago

Diego Biurrun	66baa45801	configure: Drop fastdiv option There is no point in having the user disable any fastdiv macros. Besides the condition implementation was broken and only disabled the C implementation, but no platform specific assembly versions.	12 years ago
Diego Biurrun	4264a0dd54	build: Make the E-AC-3 encoder select the AC-3 encoder The E-AC-3 encoder depends on almost all of the code of the AC-3 encoder, so it makes no sense to enable one without the other.	12 years ago

Jan Ekström	2e2d0b1142	fate: make Ut Video encoder tests use bitexact swscale flags The failures on various architectures and compilers on the RGB(A) tests seem to have been because of one-off YCbCr->RGB conversion results.
