2013-06-17Change the encryption feature to use a callback for decryption.Jeff Petkau
This allows code calling the library can choose an arbitrary encryption algorithm. Decoder control parameter VP8_SET_DECRYPT_KEY is renamed to VP8D_SET_DECRYPTOR, and now takes an small config struct instead of just a byte array. Change-Id: I0462b3388d8d45057e4f79a6b6777fe713dc546e

2012-09-11fix valgrind mem leak on garbage decodeJim Bankoski
Multiple decoders were getting allocated per frame. If the decoder crashed we exitted with out freeing them and the next time in we'd allocate over. This fix removes the allocation and just has 8 boolcoders in the pbi structure Change-Id: I638b5bda23b622b43b7992aec21dd7cf6f6278da

2012-04-24Simplifies decoder multithread synchingAttila Nagy
Increment the last_row_mb_col counter by nsync after last MB of row is ready. This way we dont need to check for last MB of row when synching. Set last MB of row ready just after row extension is done, This avoids o potential race condition whit the processing of last MB of next row. Change-Id: I19c44fd6041116ee5483be2143b4f4bfcd149eac

2012-01-30New RTCD implementationJohn Koleszar
This is a proof of concept RTCD implementation to replace the current system of nested includes, prototypes, INVOKE macros, etc. Currently only the decoder specific functions are implemented in the new system. Additional functions will be added in subsequent commits. Overview: RTCD "functions" are implemented as either a global function pointer or a macro (when only one eligible specialization available). Functions which have RTCD specializations are listed using a simple DSL identifying the function's base name, its prototype, and the architecture extensions that specializations are available for. Advantages over the old system: - No INVOKE macros. A call to an RTCD function looks like an ordinary function call. - No need to pass vtables around. - If there is only one eligible function to call, the function is called directly, rather than indirecting through a function pointer. - Supports the notion of "required" extensions, so in combination with the above, on x86_64 if the best function available is sse2 or lower it will be called directly, since all x86_64 platforms implement sse2. - Elides all references to functions which will never be called, which could reduce binary size. For example if sse2 is required and there are both mmx and sse2 implementations of a certain function, the code will have no link time references to the mmx code. - Significantly easier to add a new function, just one file to edit. Disadvantages: - Requires global writable data (though this is not a new requirement) - 1 new generated source file. Change-Id: Iae6edab65315f79c168485c96872641c5aa09d55
2011-12-21Remove opaque pointer VP8D_PTRJohn Koleszar
Use an opaque struct rather than typecasting through VP8D_PTR, an int*. Change-Id: Ia260b7d53d7e0950cfa1e00f4ecead1099bd3b87
2011-12-15Moved dequant idct into commonScott LaVarnway
These functions are now used by the encoder. This is WIP with the goal of creating a common idct/add for the encoder and decoder. A boost of 1.8% was seen for the HD rt test clip used. [Tero] Added needed changes to ARM side. Change-Id: Ibbb8000be09034203d7adffc457d3c3f8b06a5bf
2011-11-01Changing decoder input partition API to input fragments.Stefan Holmer
Adding support for several partitions within one input fragment. This is necessary to fully support all possible packetization combinations in the VP8 RTP profile. Several partitions can be transmitted in the same packet, and they can only be split by reading the partition lengths from the bitstream. Change-Id: If7d7ea331cc78cb7efd74c4a976b720c9a655463

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

2011-06-28New 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.

2011-05-19Adding error-concealment to the decoder.Stefan Holmer
The error-concealer is plugged in after any motion vectors have been decoded. It tries to estimate any missing motion vectors from the motion vectors of the previous frame. Intra blocks with missing residual are replaced with inter blocks with estimated motion vectors. This feature was developed in a separate sandbox (sandbox/holmer/error-concealment).

2010-10-27Eliminate more warnings.Timothy B. Terriberry
This eliminates a large set of warnings exposed by the Mozilla build system (Use of C++ comments in ISO C90 source, commas at the end of enum lists, a couple incomplete initializers, and signed/unsigned comparisons). It also eliminates many (but not all) of the warnings expose by newer GCC versions and _FORTIFY_SOURCE (e.g., calling fread and fwrite without checking the return values). There are a few spurious warnings left on my system: ../vp8/encoder/encodemb.c:274:9: warning: 'sz' may be used uninitialized in this function gcc seems to be unable to figure out that the value shortcut doesn't change between the two if blocks that test it here. ../vp8/encoder/onyx_if.c:5314:5: warning: comparison of unsigned expression >= 0 is always true ../vp8/encoder/onyx_if.c:5319:5: warning: comparison of unsigned expression >= 0 is always true This is true, so far as it goes, but it's comparing against an enum, and the C standard does not mandate that enums be unsigned, so the checks can't be removed.

2010-09-23Adjust multi-thread sync ranges according to image sizesYunqing Wang

2010-09-17Restructure multi-threaded decoderYunqing Wang
On each MB, loopfiltering is done right after MB decoding. This combines two loops in multi-threaded code into one, which reduces number of synchronizations to half. The above-row/left-col data are saved in temp buffers for next-row/next MB decoding. Tests on 4-core gLucid machine showed 10% decoder performance gain with threads=4 (tulip clip). Testing on other platforms isn't done yet. Change-Id: Id18ea7c1e84965dabea65d4c01ca5bc056ddeac9
2010-09-09Improved subset block searchScott LaVarnway
Improved the subset block search and fill. (about 3% improvement for 32 bit) Modified/merged the code in order to create vp8_read_mb_modes_mv which can decode the modes/mvs on a macroblock level. This will allow the decode loop (in the future) to decode modes/mvs on a frame, row, or mb level. Change-Id: If637d994b508792f846d39b5d44a7bf9aa5cddf3

2010-08-10First modification of multi-thread decoderYunqing Wang
This is the first modification of VP8 multi-thread decoder, which uses same threads to decode macroblocks and then do loopfiltering for each frame. Inspired by Rob Clark, synchronization was done on every 8 macroblocks instead of every macroblock to reduce lock contention. Comparing with the original code, this implementation gave about 15%- 20% performance gain while decoding my test clips on a Core2 Quad platform (Linux). The work is not done yet. Test on other platforms are needed. Change-Id: Ice9ddb0b511af1359b9f71e65066143c04fef3b5
