* x86inc: Avoid creating unnecessary local labelsHenrik Gramner2016-01-23
| | | | | | | | | | | | The REP_RET workaround is only needed on old AMD cpus, and the labels clutter up the symbol table and confuse debugging/profiling tools, so use EQU to create SHN_ABS symbols instead of creating local labels. Furthermore, skip the workaround completely in functions that definitely won't run on such cpus. Note that EQU is just creating a local label when using nasm instead of yasm. This is probably a bug, but at least it doesn't break anything. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* x86inc: Simplify AUTO_REP_RETHenrik Gramner2016-01-23

* x86inc: Preserve arguments when allocating stack spaceHenrik Gramner2016-01-23
| | | | | | | | When allocating stack space with a larger alignment than the known stack alignment a temporary register is used for storing the stack pointer. Ensure that this isn't one of the registers used for passing arguments. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* x86inc: Improve FMA instruction handlingHenrik Gramner2016-01-23
| | | | | | | | | | | | | | * Correctly handle FMA instructions with memory operands. * Print a warning if FMA instructions are used without the correct cpuflag. * Simplify the instantiation code. * Clarify documentation. Only the last operand in FMA3 instructions can be a memory operand. When converting FMA4 instructions to FMA3 instructions we can utilize the fact that multiply is a commutative operation and reorder operands if necessary to ensure that a memory operand is used only as the last operand.

The openh264 option is dropped altogether since it is just a fallback for -max_nal_size anyway. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

* lavc: Move frame_skip_* to codec private optionsVittorio Giovara2016-01-21
| | | | | | | | | | | | | | These options are only used by mpegvideoenc and vpx. They are very codec-specific options, so deprecate the global variants. Add an allowed value to the private options for frame_skip_cmp which seems to have been forgotten, but perfectly working. The libvpx frame dropping feature uses one of such option (frame_skip_threshold) without the other three. For this reason rename the option to something more consistent with the other libvpx variables. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

* configure: Improve requesting specific featuresLuca Barbato2016-01-21
| | | | | | | | | | | | | | | | | | Before this patch trying to enable only https by issuing --disable-protocols --enable-protocol=https --enable-gnutls does not enable https, and --disable-all --enable-protocols does not enable libavformat and the protocols component. Now the default-enabled options are set after the explicitly disabled/enabled options are evaluated. If an explicitly enabled option cannot be enabled configure will fail printing an error message.

* libkvazaar: Set frame rate as a rational numberArttu Ylä-Outinen2016-01-19
| | | | | | | | | | | | Updates libkvazaar to pass the exact frame rate to Kvazaar by setting the numerator and denominator separately instead of a single floating point number. The exact frame rate is needed for writing timing info to the bitstream. Requires Kvazaar version 0.8.1.

* flvdec: Add sanity checking of the last packet sizeMartin Storsjö2016-01-19
| | | | | | | | For http, this avoids spurious warnings about failed requests (e.g. HTTP error 416 Requested Range Not Satisfiable), if the last packet is truncated and the size read is bogus. Signed-off-by: Martin Storsjö <martin@martin.st>
* flvdec: perform duration search just onceMichael Niedermayer2016-01-19
| | | | | | | | When loading a truncated flv file, it would previously try to do a seek to the end of every packet read. For some input protocols (such as http), such repeated seek attempts are cripple the reading performance. Signed-off-by: Martin Storsjö <martin@martin.st>

* dca: fix misaligned access in ff_dca_convert_bitstreamAndreas Cadhalpun2016-01-15
| | | | | | | | | | | | The function is used on unaligned buffers (such as those provided by AVPacket), accessing them as uint16_t causes SIGBUS crashes on architectures like SPARC.

* nvenc: generate dts properlyAnton Khirnov2016-01-12
| | | | | | | | | | When there is a non-zero decoding delay due to reordering, the first dts should be lower than the first pts (since the first packet fed to the decoder does not produce any output). Use the same scheme used in mpegvideo_enc (which comes from x264 originally) -- wait for first two timestamps and extrapolate linearly to the past to produce the first dts value.
