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: NAndreas Cadhalpun <Andreas.Cadhalpun@googlemail.com> Signed-off-by: NLuca Barbato <lu_zero@gentoo.org>

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.

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).

Otherwise, closing the encoder can crash.

Change 'nvenc_<codec>' to '<codec>_nvenc', which is consistent with other similar decoders and encoders (QSV, MMAL).

This test does no encoding, setting the flag was done just to silence the warning removed in the previous commit.

The AVStream codec context is often not (and should not be) the actual encoding context, so this warning will be spurious in many cases.

Use two separate functions, depending on whether VFP/NEON is available. This is set to require armv5te - it uses blx, which is only available since armv5t, but we don't have a separate configure item for that. (It also uses ldrd, which requires armv5te, but this could be avoided if necessary.) Signed-off-by: NMartin Storsjö <martin@martin.st>

Before 741b494f, 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.

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
