* dxva2_hevc: re-write reference frame handlingHendrik Leppkes2015-05-31
| | | | | | | The old logic required an explicit clearing of the lists first and was prone to overflow the DXVA2 struct in some circumstances. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

* mov: always check avio_read return valueAndreas Cadhalpun2015-05-31
| | | | | | | | | | | 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 documentationwm42015-05-28
| | | | | | | | | | | | | | | | | | | | 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.

* x86inc: Clear __SECT__Timothy Gu2015-05-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Silences warning(s) like: libavcodec/x86/fft.asm:93: warning: section flags ignored on section redeclaration The cause of this warning is that because `struc` and `endstruc` attempts to revert to the previous section state [1]. The section state is stored in the macro __SECT__, defined by x86inc.asm to be `.note.GNU-stack ...`, through the `SECTION` directive [2]. Thus, the `.note.GNU-stack` section is defined twice (once in x86inc.asm, once during `endstruc`), causing the warning. That is the first part of the commit: using the primitive `[section]` format for .note.GNU-stack etc., which does not update `__SECT__` [2]. That fixes only half of the problem. Even without any `SECTION` directives, `__SECT__` is predefined as `.text`, which conflicting with the later `SECTION_TEXT` (which expands to `.text align=16`).
