2011-09-19Fix necessary for input partitions iface to match the RTP profileStefan Holmer
These changes fixes a glitch between the RTP profile and the input partitions interface. Since there's no way for the user to know the actual number of partitions, the decoder have to read the multi_token_paritition bits also when input partitions mode is enabled. Included are also a couple of fixes for issues with independent partitions and uninitialized memory reads. Change-Id: I6f93b15287d291169ed681898ed3fbcc5dc81837

2011-08-24Removed bmi copy to/from BLOCKDScott LaVarnway
for SPLITMV and B_PRED modes. Modified code to use the bmi found in mode_info_context instead of BLOCKD. On the decode side, the uvmvs are calculated only when required, instead of every macroblock. This is WIP. (bmi should eventually be removed from BLOCKD) Small performance gains noticed for RT encodes and decodes.(VGA) Change-Id: I2ed7f0fd5ca733655df684aa82da575c77a973e7

2011-08-15Don't set the bmi mode when doing error concealmentStefan Holmer
Since the block will be interpreted as an inter block, the mode will be interpreted as a motion vector, resulting in bad concealment. Change-Id: Ifcc685ae1cc883492bce6dbd61e418d91a89b053
2011-08-12Propagate macroblock MV to subblocks for error concealmentJohn Koleszar
EC expects the subblock MVs to be populated, but f1d6cc79e43f0066632f19c1854ca365086b712b removed this code. This commit restores it, protected by CONFIG_ERROR_CONCEALMENT. May move this to the EC code more directly in the future. Change-Id: I44f8f985720cb9a1bf222e59143f9e69abf56ad2
2011-08-12Disable error concealment until first key frame is decodedStefan Holmer
When error concealment is enabled the first key frame must be successfully received before error concealment is activated. Error concealment will be activated when the delta following delta frame is received. Also fixed a couple of bugs related to error tracking in multi-threading. And avoiding decoding corrupt residual when we have multiple non-resilient partitions. Change-Id: I45c4bb296e2f05f57624aef500a874faf431a60d
2011-08-12Fix potential OOB read with Error ConcealmentJohn Koleszar
This patch fixes an OOB read when error concealment is enabled and the partition sizes are corrupt. The partition size read from the bitstream was not being validated in EC mode. Change-Id: Ia81dfd4bce1ab29ee78e42320abe52cee8318974

2011-07-22fix sharpness bug and clean upJohann
sharpness was not recalculated in vp8cx_pick_filter_level_fast remove last_filter_type. all values are calculated, don't need to update the lfi data when it changes. always use cm->sharpness_level. the extra indirection was annoying. don't track last frame_type or sharpness_level manually. frame type only matters for motion search and sharpness_level is taken care of in frame_init move function declarations to their proper header Change-Id: I7ef037bd4bf8cf5e37d2d36bd03b5e22a2ad91db

Separate simple filter with reduced no. of parameters. MB filter level picking based on precalculated table. Level table updated for each frame. Inside and edge limits precalculated and updated just when sharpness changes. HEV threshhold is constant. ARM targets use scalars and others vectors.

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.

2011-06-27Adding support for error concealment in multi-threaded decodingStefan Holmer
