configure: add dxva2 extralibs to avcodec · 4ec2daf0

James Almer authored Jan 06, 2019

DXVA2 may be enabled even when every relevant module is disabled,
which would result in the dependency generator not including its
extralibs to avcodec.

avformat/vapoursynth: properly initialize err variable in read_header_vs() · e0686318

The variable "err" is not initialized, and set only when something went wrong.
When everything is OK, nobody sets it, so using it result in UB.

libavcodec: Remove dynamic relocs from aarch64/h264idct_neon.S · 6fcf8131

Manoj Gupta authored Dec 28, 2018

Some of the assembly functions e.g. ff_h264_idct_dc_add_neon
has code like:
        movrel          x14, X(ff_h264_idct_add_neon)

Linker cannot resolve them fully at link time and emits dynamic
relocations.
Use explicit labels instead so that no dynamic relocations are
needed at all.

This avoids lld complains about text relocations.

Previously, a few packets from such streams, probably buffered for

mov: Remove duration-of-last-frame heuristic hack · 8f585c3c

Derek Buitenhuis authored Dec 24, 2018

This breaks totally valid files that get caught in its heuristic.

This, according to the commit message, is my own doing, having asked
Michael to implement this check and providing a sample that was
"wrong". I am now atoning for my sins, and removing this hack, having
seen the light (aka that this was silly to do in the first place).

Resotores correct behavior on valid files.

This reverts commit 8e5e84c2.
