2011-06-28New ways of passing encoded data between encoder and decoder.Stefan Holmer
With this commit frames can be received partition-by-partition from the encoder and passed partition-by-partition to the decoder. At the encoder-side this makes it easier to split encoded frames at partition boundaries, useful when packetizing frames. When VPX_CODEC_USE_OUTPUT_PARTITION is enabled, several VPX_CODEC_CX_FRAME_PKT packets will be returned from vpx_codec_get_cx_data(), containing one partition each. The partition_id (starting at 0) specifies the decoding order of the partitions. All partitions but the last has the VPX_FRAME_IS_FRAGMENT flag set. At the decoder this opens up the possibility of decoding partition N even though partition N-1 was lost (given that independent partitioning has been enabled in the encoder) if more info about the missing parts of the stream is available through external signaling. Each partition is passed to the decoder through the vpx_codec_decode() function, with the data pointer pointing to the start of the partition, and with data_sz equal to the size of the partition. Missing partitions can be signaled to the decoder by setting data != NULL and data_sz = 0. When all partitions have been given to the decoder "end of data" should be signaled by calling vpx_codec_decode() with data = NULL and data_sz = 0. The first partition is the first partition according to the VP8 bitstream + the uncompressed data chunk + DCT address offsets if multiple residual partitions are used.

2011-06-28Avoid text relocations in ARM vp8 decoderMike Hommey
The current code stores pointers to coefficient tables and loads them to access the tables contents. As these pointers are stored in the code sections, it means we end up with text relocations. eu-findtextrel will thus complain about code not compiled with -fpic/-fPIC. Since the pointers are stored in the code sections, we can actually cheat and let the assembler generate relative addressing when accessing the coefficient tables, and just load their location with adr.

2011-06-23Revert "Reduce overshoot in 1 pass rate control"John Koleszar
This reverts commit 212f6183739d448ad5fa2ccf1b4edd30829b2806. Further testing shows that the overshoot accumulation/damping is too aggressive on some clips. Allowing the accumulated overshoot to decay and limiting to damping to golden frames shows some promise. But some clips show significant overshoot in the buffer window, so I think this still needs work. Change-Id: Ic02a9ca34f55229f9cc04786f4fab54cdc1a3ef5

2011-06-20adjusting the calculation of errorperbitYaowu Xu
RDMULT/RDDIV defines a bit worth of distortion in term of sum squared difference. This has also been used as errorperbit in subpixel motion search, where the distortions computed as variance of the difference. The variance of differences is different from sum squared differences by amount of DC squared. Typically, for inter predicted MBs, this difference averages around 10% between the two distortion, so this patch introduces a 110% constant in deriving errorperbit from RDMULT/RDDIV. Test on CIF set shows small but positive gain on overall PSNR (.03%) and SSIM (.07%), overall impact on average PSNR is 0. Change-Id: I95425f922d037b4d96083064a10c7cdd4948ee62

2011-06-17Merge "Use SSE as BPRED distortion metric consistently"John Koleszar
2011-06-16Assign boost to GF bit allocation if past frame had no ARF.Ronald S. Bultje
Modify the second-pass code to provide a full golden-frame (GF) bit allocation boost if the past GF group (GFG) had no alt-ref frame (ARF), even if the current GFG does contain and ARF. This mostly has no effect on clips, since switching ARFs on/off between GFGs is not very common. Has a positive effect on e.g. cheer (+0.45 SSIM at 600kbps) and football (+0.25 SSIM at 600kbps), particularly at high bitrates. Has a negative effect (-0.04 SSIM at 300kbps) at pamphlet, which appears only marginally related to this patch, and crew (-0.1 SSIM at 700kbps). Change-Id: I2e32899638b59f857e26efeac18a82e0c0b77089

2011-06-15Disable specialcase for last frames if the sequence contains ARFs.Ronald S. Bultje
firstpass.c contains some rate adjustment code that assures that the last few frames in a sequence abide by rate limits. If the second-to- last group of frames contains an alt-ref frame (ARF), the last golden frame (GF) is zero bytes, and we will thus spend a ridiculously high number of bits on regular P-frames trying to hit the target rate. This does slightly enhance the quality of these last few frames, but has no perceptual value (other than hitting the target rate). Disabling this code means we consistently (slightly) undershoot the target rate and consequently do worse on the last few frames of a clip, which is particularly noticeable for small clips. The quality- per-bitrate is generally better, ~0.2% better overall on derf-set, especially on clips such as garden, tennis, foreman at low bitrates. Has a negative effect on hallmonitor at high bitrates. Change-Id: I1d63452fef5fee4a0ad2fb2e9af4c9f2e0d86d23
