  hwcontext_vaapi: Try the first render node as the default DRM device
  
  If no string argument is supplied when av_hwdevice_ctx_create() is
  called to create a VAAPI device, we currently only try the default
  X11 display (that is, $DISPLAY) to find a device, and will therefore
  fail in the absence of an X server to connect to.  Change the logic
  to also look for a device via the first DRM render node (that is,
  "/dev/dri/renderD128"), which is probably the right thing to use in
  most simple configurations which only have one DRM device.

  avcodec/bsf: Add ff_bsf_get_packet_ref() function
  
  Use of this function can save unnecessary malloc operation
  in bitstream filter.

• libavutil : Use an intermediate variable in AV_COPY*U

  28 juillet 2016, par Martin Storsjö

  libavutil: Use an intermediate variable in AV_COPY*U
  
  If AV_RN and AV_WN are macros with multiple individual reads and
  writes, the previous version of the AV_COPYU macro would fail if
  the reads and writes overlap.
  
  This should not be any less efficient in any case, given a
  sensibly optimizing compiler.
