* Improve QTRLE encoding performance, no change to output file size/content.Malcolm Bechard2013-02-22
| | | | | | | Avoid searching for the lowest bulk cost for each pixel that isn't a repeat/skip. Instead store the lowest cost as we go along each pixel, and use it as needed. Signed-off-by: Malcolm Bechard <malcolm.bechard@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

* exr: fix overflow check in lineoffset processingPaul B Mahol2013-02-22
| | | | | | | | | | | Also read data size for raw compressions too and make sure its value is sane. Remove code that fills missing blocks with zeroes. It is marginally useful and make implementation of actually useful features harder. Signed-off-by: Paul B Mahol <onemda@gmail.com>

|\| | | | | | | | | | | | | | | | | | | | | * commit '8a11ce43d08352f7a290355ebb5b29c495ad9609': build: Ensure that output directories for header objects are created h264: Get rid of unnecessary casts Conflicts: common.mak Merged-by: Michael Niedermayer <michaelni@gmx.at>
| * h264: Get rid of unnecessary castsMartin Storsjö2013-02-20
| | | | | | | | | | | | | | This gets rid of a number of warnings about casts discarding qualifiers from the pointer target, present since 7ebfb466a. Signed-off-by: Martin Storsjö <martin@martin.st>
| * h264/svq3: Stop using draw_edgesRonald S. Bultje2013-02-19
| | | | | | | | | | | | | | | | | | | | | | Instead, only extend edges on-demand when the motion vector actually crosses the visible decoded area using ff_emulated_edge_mc(). This changes decoding time for cathedral from 8.722sec to 8.706sec, i.e. 0.2% faster overall. More generally (VP8 uses this also), low-motion content gets significant speed improvements, whereas high-motion content tends to decode in approximately the same time. Signed-off-by: Martin Storsjö <martin@martin.st>
| * h264: Don't store intra pcm samples in h->mbRonald S. Bultje2013-02-19
| | | | | | | | | | | | | | | | | | Instead, keep them in the bitstream buffer until we read them verbatim, this saves a memcpy() and a subsequent clearing of the target buffer. decode_cabac+decode_mb for a sample file (CAPM3_Sony_D.jsv) goes from 6121.4 to 6095.5 cycles, i.e. 26 cycles faster.

| * get_bits: Return pointer to buffer that is the result of the alignmentRonald S. Bultje2013-02-19
| | | | | | | | | | | | | | This allows more transparent mixing of get_bits and whole-byte access without having to touch get_bits internals. Signed-off-by: Martin Storsjö <martin@martin.st>

| * h264: Add add_pixels4/8() to h264dsp, and remove add_pixels4 from dsputilRonald S. Bultje2013-02-19
| | | | | | | | | | | | | | | | | | These functions are mostly H264-specific (the only other user I can spot is bink), and this allows us to special-case some functionality for H264. Also remove the 16-bit-coeff with >8bpp versions (unused) and merge the duplicate 32-bit-coeff for >8bpp (identical). Signed-off-by: Martin Storsjö <martin@martin.st>
| * h264chroma: Remove duplicate 9/10 bit functionsRonald S. Bultje2013-02-19
| | | | | | | | | | | | | | These functions do the same thing in 16 bit space and don't need any depth specific clipping. Signed-off-by: Martin Storsjö <martin@martin.st>
| * vp56: Remove clear_blocks call, and clear alpha plane U/V DC onlyRonald S. Bultje2013-02-19
| | | | | | | | | | | | | | | | The non-alpha and alpha-Y planes are cleared in the idct_put/add() calls. For the alpha U/V planes, we only care about the DC for entropy context prediction purposes, the rest of the data is unused. Signed-off-by: Martin Storsjö <martin@martin.st>

| | | | | | | | | | | | | | | | | | | | | | | | | | The new code is also faster and more robust. As for the performance: old decoder + conversion to rgb: fps = 2618 old decoder, without converting to rgb: fps = 4012 new decoder, producing rgb: fps = 4502 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
