* x86inc: Add debug symbols indicating sizes of compiled functionsGeza Lore2016-01-23
| | | | | | | | | | | Some debuggers/profilers use this metadata to determine which function a given instruction is in; without it they get can confused by local labels (if you haven't stripped those). On the other hand, some tools are still confused even with this metadata. e.g. this fixes `gdb`, but not `perf`. Currently only implemented for ELF. Signed-off-by: Anton Khirnov <anton@khirnov.net>

* lavc: Move pre_me to codec private optionsVittorio Giovara2016-01-21
| | | | | | | This option is only used by mpegvideoenc. It is a very codec-specific option, so deprecate the global variant. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

| | | | | | | | | | This options is only used by huffyuv, ffvhuv, jpegls, mjpeg, mpegvideoenc, png, utvideo. It is a very codec-specific options, so deprecate the global variant. Set proper limits to the maximum allowed values, and update utvideoenc tests to use the new option name. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

| | | | | | | | | | This option is only used by mpegvideoenc and openh264. It is a very codec-specific option, so deprecate the global variant. 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>

* 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.

* 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. This fixes ubsan runtime error: load of misaligned address for type 'const uint16_t', which requires 2 byte alignment Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* xwddec: prevent overflow of lsize * avctx->heightAndreas Cadhalpun2016-01-13
| | | | | | | | | This is used to check if the input buffer is larger enough, so if this overflows it can cause a false negative leading to a segmentation fault in bytestream2_get_bufferu.

* on2avc: limit number of bits to 30 in get_egolombAndreas Cadhalpun2016-01-13
| | | | | | | | | | More don't fit into the integer output. Also use get_bits_long, since get_bits only supports reading up to 25 bits, while get_bits_long supports the full integer range.

* 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.
* nvenc: fix encoding with B-framesAnton Khirnov2016-01-12
| | | | | | | | | | | When B-frames are enabled and the encoder returns success, all currently pending buffers immediately become valid and can be returned to the caller. We can only return one packet at a time, so all the other pending buffers should be transferred to a new 'ready' fifo, from where they can be returned in subsequent calls (in which the encoder does not produce any new output). This bug was hidden by the incorrect testing of the encoder return value (the return value was overwritten before it was tested).
* nvenc: flush the encoder before closing it, as required by the docsAnton Khirnov2016-01-12
| | | | Otherwise, closing the encoder can crash.
* nvenc: rename encodersAnton Khirnov2016-01-12
| | | | | Change 'nvenc_<codec>' to '<codec>_nvenc', which is consistent with other similar decoders and encoders (QSV, MMAL).
* nvenc: better error handlingAnton Khirnov2016-01-12

* h264: improve behaviour with invalid reference listsAnton Khirnov2016-01-01
| | | | | | | | | | | | | Before 741b494fa8cd28a7d096349bac183893c236e3f9, when the reference list modification description was invalid, the code would substitute the corresponding reference from the initial ("default") reference list. After that commit, it will just return an error. Since there are apparently invalid samples in the wild that used to play fine with the old code, it is a good idea to re-add some sort of error resilience here. So, when the reference list modification results in a missing frame, substitute a previous reference frame for it. The relevant sample again decodes fine with the same output as previously.

* x86: use emms after ff_int32_to_float_fmul_scalar_sseJanne Grunau2015-12-30
| | | | | | | | | | | | | | | | | | | | | Intel's Instruction Set Reference (as of September 2015) clearly states that cvtpi2ps switches to MMX state. Actual CPUs do not switch if the source is a memory location. The Instruction Set Reference from 1999 (Order Number 243191) describes this behaviour but all later versions I've seen have make no distinction whether MMX registers or memory is used as source. The documentation for the matching SSE2 instruction to convert to double (cvtpi2pd) was fixed (see the valgrind bug https://bugs.kde.org/show_bug.cgi?id=210264). It will take time to get a clarification and fixes in place. In the meantime it makes sense to change ff_int32_to_float_fmul_scalar_sse to be correct according to the documentation. The vast majority of users will have SSE2 so a change to the SSE version has little effect. Fixes fate-checkasm on x86 valgrind targets. Valgrind 'bug' reported as https://bugs.kde.org/show_bug.cgi?id=357059
