- dxva2_hevc: re-write reference frame handling · 902a55f7
  Hendrik Leppkes authored May 28, 2015
```
The old logic required an explicit clearing of the lists first and was
prone to overflow the DXVA2 struct in some circumstances.

- mov: always check avio_read return value · 5c720657
  Andreas Cadhalpun authored May 26, 2015
```
If avio_read fails, the buffer can contain uninitialized data.

This fixes 'Conditional jump or move depends on uninitialised value(s)'
valgrind warnings, and addresses a few memleaks.

pixfmt: remove misleading and broken documentation · a64a5773

wm4 authored May 28, 2015

This was probably broken some time ago. The breakage is now part of the
ABI. For example, we have:

    AV_PIX_FMT_XYZ12BE
    AV_PIX_FMT_NV16
    AV_PIX_FMT_NV20LE

AV_PIX_FMT_NV20LE is wrong. It has the value 113, but as little-endian
format it should be even. This must have been quite obvious when these
formats were added (because of the AV_PIX_FMT_XYZ12BE entry), but
nobody cared or knew about this.

The future libavutil major bump will also break this additionally,
because disabling FF_API_VDPAU will remove an odd number of entries from
the middle of the enum.
