Diego Biurrun	acf91215c7	x86: dsputil: Avoid pointless CONFIG_ENCODERS indirection The remaining dsputil bits are encoding-specific anyway.	11 years ago
Ben Avison	42c1cc35b7	armv6: Accelerate ff_imdct_half for general case (mdct_bits != 6) The previous implementation targeted DTS Coherent Acoustics, which only requires mdct_bits == 6. This relatively small size lent itself to unrolling the loops a small number of times, and encoding offsets calculated at assembly time within the load/store instructions of each iteration. In the more general case (codecs such as AAC and AC3) much larger arrays are used - mdct_bits == [8, 9, 11]. The old method does not scale for these cases, so more integer registers are used with non-unrolled versions of the loops (and with some stack spillage). The postrotation filter loop is still unrolled by a factor of 2 to permit the double-buffering of some VFP registers to facilitate overlap of neighbouring iterations. I benchmarked the result by measuring the number of gperftools samples that hit anywhere in the AAC decoder (starting from aac_decode_frame()) or specifically in ff_imdct_half_c / ff_imdct_half_vfp, for the same example AAC stream: Before After Mean StdDev Mean StdDev Confidence Change aac_decode_frame 2368.1 35.8 2117.2 35.3 100.0% +11.8% ff_imdct_half_* 457.5 22.4 251.2 16.2 100.0% +82.1% Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Oliver Fromme	a32dcaaaf8	avcodec/dvdsubenc: Add dvdsub workaround for some players The issue affects dvdsub subtitles (a.k.a. VOBSUB). Some players -- in particular hardware players -- cut off the lowest row of pixels if the number of rows in the subtitle is odd. The patch below implements a work-around for that. If the number of rows is odd, it is simply rounded up to an even number, adding an invisible (i.e. fully transparent) row. The work-around can be enabled or disabled with a new option -even_rows_fix. The default is disabled, so there is no change of behaviour for users who don't care about it. The overhead for the fix is low, and in many cases even zero: For subtitles with an odd number of rows (i.e. in 50% of cases on average), the size increases by two bytes because a fully transparent row is encoded as 0x00 0x00. However, in the VOBSUB standard, all data packets are padded to 2KB anyway, so in most cases the additional bytes just use some part of the padding, so there is no overhead. Only in the rare case that the 2KB boundary is hit (0.1% chance), a full 2KB block is added. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
