2011-07-21fix more merge issuesYaowu Xu
With this fix, the experimental branch now builds and encodes correctly with the following two configure options respectively: --enable-experimental --enable-t8x8 --enable-experimental Change-Id: I3147c33c503fe713a85fd371e4f1a974805778bf
2011-07-20fixed a number of problems caused by auto mergesYaowu Xu
The auto merge process pull and merge commits from public git or master branch. These automerges while worked well most time, but has created a few problems. This commit fixed several issues existed long before the latest 8x8 transform commit. Change-Id: I895ca99713231b1aec521d57db5d9839f74aacfa

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.

2011-05-24MODE_INFO size reductionScott LaVarnway
Declared the bmi in MODE_INFO as a union instead of B_MODE_INFO. This reduced the memory footprint by 518,400 bytes for 1080 resolutions. The decoder performance improved by ~4% for the clip used and the encoder showed very small improvements. (0.5%) This reduction was first mentioned to me by John K. and in a later discussion by Yaowu. This is WIP. Change-Id: I8e175fdbc46d28c35277302a04bee4540efc8d29

2010-11-11Use of temporal context for encoding delta updates.Suman Sunkara
- Used three probability approach for temporal context as follows: P0 - probability of no change if both above and left not changed P1 - probability of no change if one of above and left has changed P2 - probability of no change if both above and left have changed In addition, a 1 bit/frame has been used to decide whether to use temporal context or to encode directly. The cost of using both the schemes is calculated ahead and the temporal_update flag is set if the cost of using temporal context is lower than encoding the segment ids directly. This approach has given around 20% reduction in cost of bits needed to encode segmentation ids. Change-Id: I44a5509599eded215ae5be9554314280d3d35405
2010-09-29Fix loopfilter delta zero transitionsJohn Koleszar
Loopfilter deltas are initialized to zero on keyframes in the decoder. The values then persist from the previous frame unless an update bit is set in the bitstream. This data is not included in the entropy data saved by the 'refresh entropy' bit in the bitstream, so it is effectively an additional contextual element beyond the 3 ref-frames and the entropy data. The encoder was treating this delta update bit as update-if-nonzero, meaning that the value would be refreshed even if it hadn't changed, and more significantly, if the correct value for the delta changed to zero, the update wouldn't be sent, and the decoder would preserve the last (presumably non-zero) value. This patch updates the encoder to send an update only if the value has changed from the previously transmitted value. It also forces the value to be transmitted in error resilient mode, to account for lost context in the event of lost frames. Change-Id: I56671d5b42965d0166ac226765dbfce3e5301868
2010-09-14Changed code to remove extra read/write loops when not necessarySuman Sunkara
Modified code so that: -When above and left contexts are same and not equal to current segment id, it needs to read a maximum of 2 segment_tree_probabilities. - When above and left contexts are different and not equal to current segment id, it needs to read only a single segment_tree_probability.

2010-09-13Delta updates to segmentation map using left and above contexts.Suman Sunkara

2010-09-03Reduced the size of MB_MODE_INFOScott LaVarnway
Moved partition_bmi and partition_count out of MB_MODE_INFO and placed into MACROBLOCK. Also reduced the size of other members of the MB_MODE_INFO struct. For 1080p, the memory was reduced by 1,209,516 bytes. The decoder performance appeared to improve by 3% for the clip used. Note: The main goal for this change is to improve the decoder performance. The encoder will be revisited at a later date for further structure cleanup. Change-Id: I4733621292ee9cc3fffa4046cb3fd4d99bd14613
