* | x86: hevc_mc: split differently callsChristophe Gisquet2014-08-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In some cases, 2 or 3 calls are performed to functions for unusual widths. Instead, perform 2 calls for different widths to split the workload. The 8+16 and 4+8 widths for respectively 8 and more than 8 bits can't be processed that way without modifications: some calls use unaligned buffers, and having branches to handle this was resulting in no micro-benchmark benefit. For block_w == 12 (around 1% of the pixels of the sequence): Before: 12758 decicycles in epel_uni, 4093 runs, 3 skips 19389 decicycles in qpel_uni, 8187 runs, 5 skips 22699 decicycles in epel_bi, 32743 runs, 25 skips 34736 decicycles in qpel_bi, 32733 runs, 35 skips After: 11929 decicycles in epel_uni, 4096 runs, 0 skips 18131 decicycles in qpel_uni, 8184 runs, 8 skips 20065 decicycles in epel_bi, 32750 runs, 18 skips 31458 decicycles in qpel_bi, 32753 runs, 15 skips Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

* | wavpackenc: reset trailer info on block encodingChristophe Gisquet2014-08-22
| | | | | | | | | | | | | | | | | | | | | | In some cases, in particular if several blocks are needed because of the channel layout (e.g. 2.1), the information used to write the trailing bits terminating the sample data was not reset. This would cause potential desync on the decoder, although decoded samples were actually mostly fine. Fixes ticket #3879.
* | wavpack: check number of channelsChristophe Gisquet2014-08-22
| | | | | | | | | | This means container and codec disagree. The codec is supposed to know better so this could be an error instead.

|\| | | | | | | | | | | | | * commit 'dc4b2e7d33903a6b9380e8a84b22b3a20facbb08': rv34: use ff_mpeg_update_thread_context only when decoder is fully initialized Merged-by: Michael Niedermayer <michaelni@gmx.at>
| * 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.

* | avcodec: fix aac/ac3 parser bitstream buffer sizeMichael Niedermayer2014-08-22
| | | | | | | | | | | | | | | | | | | | | | Buffers containing copies of the AAC and AC3 header bits were not padded before parsing, violating init_get_bits() buffer padding requirement, leading to potential buffer read overflows. This change adds FF_INPUT_BUFFER_PADDING_SIZE bytes to the bit buffer for parsing the header in each of aac_parser.c and ac3_parser.c.

* | imc: reject files with unfathomable sampling ratesChristophe Gisquet2014-08-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | With huge sampling rates, the table derivation method does not converge fast enough. While fixing it using e.g. Newton-Rhapson-like methods (the curve is nicely convex) is possible, it is much simpler to reject these cases. The value of 96000 was arbitrarily chosen as a realistic value, though 1000000 would still work and converge. Fixes ticket #3868.
