Henrik Gramner	a344e5d094	x86: bswapdsp: Don't treat 32-bit integers as 64-bit The upper halves are not guaranteed to be zero in x86-64. Also use `test` instead of `and` when the result isn't used for anything other than as a branch condition, this allows some register moves to be eliminated.

Dave Yeo	4da585ae47	OS/2: Cleanup slib_create_def_cmd Export symbols by name rather then ordinal. Remove PROTMODE directive as it does not make sense for 32 bit library.

Anton Khirnov	a062a55d37	hevc_parser: fix standalone build with the hevc decoder disabled The parser depends on hevc_ps, which in turn needs some data tables. Found-by: James Almer <jamrial@gmail.com>	10 years ago
Anton Khirnov	b9f76d19d8	hevc_ps: make sure failing to decode an SPS always returns an error Some of the goto err clauses do not set the error code. It seems better to fall back on INVALIDDATA instead of adding it everywhere explicitly.	10 years ago
Anton Khirnov	077b559433	hevc: handle a NULL sps in set_sps() properly This can happen in update_thread_context(), when the previous frame was corrupted.	10 years ago
Anton Khirnov	18156b53f9	hevc: do not pass an entire HEVCContext into export_stream_params() It only needs the parameter sets.	10 years ago
Anton Khirnov	650060dfb6	hevc_parser: parse and export some stream parameters Particularly those that will be needed by the QSV decoder. More can be added later as necessary.	10 years ago
Anton Khirnov	7f78155dc6	hevc: improve a comment That loop does the actual full decoding, so 'parse' can be misleading.	10 years ago
Anton Khirnov	d82e1adc20	hevc: move splitting the packet into NALUs into a separate function This function is independent of the decoding context, so we'll be able to use it in the parser.	10 years ago
Anton Khirnov	ae05b48655	hevc: eliminate the second call to hls_nal_unit() Also, make hls_nal_unit() work only on the provided NAL unit, without requiring a whole decoding context. This will allow splitting this code for reuse by the parser.	10 years ago
Anton Khirnov	d7bebe4805	hevc: skip invalid/ignored NALUs when splitting the packet There is no need to wait until actually decoding the NALU. This will allow to get rid of the second hls_nal_unit() call later.	10 years ago
Anton Khirnov	b11acd5732	hevc: remove HEVCContext usage from hevc_ps Factor out the parameter sets into a separate struct and use it instead. This will allow us to reuse this code in the parser.	10 years ago

Anton Khirnov	86eee85dad	bytestream2: set the reader to the end when reading more than available This prevents possible infinite loops with the calling code along the lines of while (bytestream2_get_bytes_left()) { ... }, where the reader does not advance. CC: libav-stable@libav.org	10 years ago
Henrik Gramner	8bc67ec2c0	Checkasm: assembly testing and benchmarking tool It provides the following features: * verify correctness by comparing output to the C version. * detect failure to save and restore clobbered callee-saved registers. * detect 32-bit parameters being used as if they were 64-bit in x86-64 (the upper halves are not guaranteed to be zero - but in practice they very often are, which makes those bugs hard to spot otherwise). * easy benchmarking. Compile by running 'make checkasm'. Execute by running 'tests/checkasm/checkasm'. Optional arguments are '--bench' to run benchmarks for all functions, '--bench=<pattern>' to run benchmarks for all functions that starts with <pattern>, and '<integer>' to seed the PRNG for reproducible results. Contains unit tests for most h264pred functions to get started, more tests can be added afterwards using those as a reference. Loosely based on code from x264. Currently only supports x86 and x86-64, but additional architectures shouldn't be too much of an obstacle to add. Note that functions with floating point parameters or floating point return values are not supported. Some compiler-specific features or preprocessor hacks would likely be required to add support for that. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	10 years ago

Andreas Cadhalpun	1410eeb6ea	imc: Use correct position for flcoeffs2 calculation flcoeffs2[pos] should be the log2 of flcoeffs1[pos]. flcoeffs1[0] can be 0 here, thus flcoeffs2[pos] gets set to -inf, causing problems further down. This seems to have been copied from imc_decode_level_coefficients in commit `4eb4bb3` without updating the position.

Henrik Gramner	d1a6cb195f	x86: Serialize rdtsc in read_time() Improves the accuracy of measurements, especially in short sections. To quote the Intel 64 and IA-32 Architectures Software Developer's Manual: "The RDTSC instruction is not a serializing instruction. It does not necessarily wait until all previous instructions have been executed before reading the counter. Similarly, subsequent instructions may begin execution before the read operation is performed. If software requires RDTSC to be executed only after all previous instructions have completed locally, it can either use RDTSCP (if the processor supports that instruction) or execute the sequence LFENCE;RDTSC." SSE2 is a requirement for lfence so only use it on SSE2-capable systems. Prefer lfence;rdtsc over rdtscp since rdtscp is supported on fewer systems.
