* h264: fully check cropping amount from spsVittorio Giovara2014-08-26
| | | | | Even if sps.crop is true, the cropping amount may be zero. Fixes a sample with a valid but broken container cropping.

* vc1: Fix the skip conditionLuca Barbato2014-08-26
| | | | | As written in the comment above, skip must be added only if a start code is found.
* rv34: use ff_mpeg_update_thread_context only when decoder is fully initializedJanne Grunau2014-08-22
| | | | | | | | | | | | | MpegEncContext based decoders are only fully initialized after the first ff_thread_get_buffer() call. The RV30/40 decoders may fail before a frame buffer was requested. ff_mpeg_update_thread_context() fails on half initialized MpegEncContexts. Since this can only happen before a the first frame was decoded there is no need to call ff_mpeg_update_thread_context(). Based on patches by John Stebbins and tested by John Stebbins.

* error_resilience: Drop asserts from guess_mv()Diego Biurrun2014-08-21
| | | | | The asserts check struct members that are not referenced in guess_mv() and one of them fails to compile.

* proresenc: Properly account for alpha planeChristophe Gisquet2014-08-18
| | | | | | | | | | The packet buffer allocation considers the alpha channel as DCT-coded, while it is actually run-coded and thus requires a larger buffer. CC: libav-stable@libav.org Signed-off-by: Diego Biurrun <diego@biurrun.de> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* proresenc: Realloc if buffer is too smallChristophe Gisquet2014-08-18
| | | | | | | | | | | | | | The buffer allocation may be incorrect (e.g. with an alpha plane), and currently causes the buffer to be set to NULL by init_put_bits, causing a crash later on. So, detect that situation, and if detected, reallocate the buffer and ask for a sample that shows the problem.

* hevc_filter: avoid excessive calls to ff_hevc_get_ref_list()Anton Khirnov2014-08-09
| | | | | | | | 1) each of the loops run within a single CTB, so the relevant reference list is constant 2) when that CTB is, or lies on the same slice as, the current one, we can use a simple access instead of a relatively expensive call to ff_hevc_get_ref_list()
* hevc_refs: drop the handling of negative coordinates in ff_hevc_get_ref_list()Anton Khirnov2014-08-09

* hevc_filter: drop more redundant checksAnton Khirnov2014-08-09
