* pass QDMC extradata to the decoderSascha Sommer2011-02-06
| | | | | | | Makes playing QDMC files in MPlayer work when using the libavformat demuxer. Problem was that the extradata was not passed from demuxer to decoder. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

* ac3enc: Change EXP_DIFF_THRESHOLD to 500.Justin Ruggles2011-02-02
| | | | | | | | | This patch changes the exponent difference threshold in the exponent strategy decision function of the AC-3 encoder. I tested lowering in increments of 100. From 1000 down to 500 generally increased in quality with each step, but 400 was generally much worse. Signed-off-by: Mans Rullgard <mans@mansr.com>

* Separate format conversion DSP functions from DSPContext.Justin Ruggles2011-02-02
| | | | | | | This will be beneficial for use with the audio conversion API without requiring it to depend on all of dsputil. Signed-off-by: Mans Rullgard <mans@mansr.com>

* VP8: merge chroma MC callsJason Garrett-Glaser2011-01-31
| | | | | Adds some duplicated code, but avoids duplicate edge checks and similar. ~0.5% faster overall on Parkjoy test sample.
* Implement a SIMD version of emulated_edge_mc() for x86.Ronald S. Bultje2011-01-31
| | | | | From ~550 cycles (C version) to 170 (SSE/x86-64), 206 (MMX/x86-32) and 196 (SSE2/x86-32) cycles.

* Flush final frames in libfaac encoder.Justin Ruggles2011-01-29

* Rearrange MpegEncContext to simplify access from asmMans Rullgard2011-01-29
| | | | | | | | | This moves the fields needed by asm near the top, before any structs or other members which complicate the offset calculation. Modifying other structs will no longer require updating the offsets, and the asm code is slightly simpler due to the smaller offsets. Signed-off-by: Mans Rullgard <mans@mansr.com>

* Optimize C version of ff_emulated_edge_mc().Ronald S. Bultje2011-01-28
| | | | | From ~780 cycles to 551 cycles, mostly just by using libc memcpy() instead of manually shuffling individual bytes around.

* Hide the now-prefixed decoders, encoders, parsers, bsf, hwaccel objects.Diego Elio Pettenò2011-01-28
| | | | | | | This significantly reduces the size of the symbol table in the generated ELF shared object (as well as the other linked tables). Signed-off-by: Mans Rullgard <mans@mansr.com>

* VP8: don't overread edges on fourtap MC.Ronald S. Bultje2011-01-26
| | | | | | | Fix C VP8 H+V MC functions which do two-dimensional 4/6-tap filters to not overread beyond their edges if the second filter is 4-tap, since the outer pixels aren't there anymore since 44002d8323023c35f51d523a7d305e45103ba7a1.
* Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.Diego Elio Pettenò2011-01-26
| | | | | | | None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>
* Make ff_cmap_read_palette static to libavcodec/iff.c. Delete iff.h.Diego Elio Pettenò2011-01-26
| | | | | | | | The iff.h header only declared one function that is now static, the libavformat/iff.c source file wasn't using it before. Drop the file entirely. Signed-off-by: Mans Rullgard <mans@mansr.com>

* ac3: Remove ff_ac3_critical_band_size_tab.Justin Ruggles2011-01-26
| | | | | | | It is only used to generate band_start_tab, which about the same size, at runtime, so it's simpler just to always hardcode band_start_tab. Signed-off-by: Mans Rullgard <mans@mansr.com>
