2011-07-28Convert rc_max_intra_bitrate_pct to controlJohn Koleszar
Since this is the only ABI incompatible change since the last release, convert it to use the control interface instead. The member of the configuration struct is replaced with the VP8E_SET_MAX_INTRA_BITRATE_PCT control. More significant API changes were expected to be forthcoming when this control was first introduced, and while they continue to be expected, it's not worth breaking compatibility for only this change.

2011-07-19Revert "Disable __longjmp_chk protection"John Koleszar
This reverts commit b73a3693e581583e9ec676f4396d0c3d173e2462. This version of the check doesn't work with generic-gnu, and figuring out the correct symbol version at configure time is probably more work than this is worth. May revisit in the future.

2011-07-13Disable __longjmp_chk protectionJohn Koleszar
glibc implements some checking on longjmp() calls by replacing it with an internal function __longjmp_chk(), when FORTIFY_SOURCE is defined. This can be problematic when compiling the library under one version of glibc and running it under another. Work around this issue for the one symbol affected for now, before taking out the undef hammer.

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).

2011-04-12Change rc undershoot/overshoot semanticsJohn Koleszar
This patch changes the rc_undershoot_pct and rc_overshoot_pct controls to set the "aggressiveness" of rate adaptation, by limiting the amount of difference between the target buffer level and the actual buffer level which is applied to the target frame rate for this frame. This patch was initially provided by arosenberg at logitech.com as an attachment to issue #270. It was modified to separate these controls from the other unrelated modifications in that patch, as well as to use the pre-existing variables rather than introducing new ones.

2011-01-19Implement error tracking in the decoderHenrik Lundin
A new vpx_codec_control called VP8D_GET_FRAME_CORRUPTED. The output from the function is non-zero if the last decoded frame contains corruption due to packet losses. The decoder is also modified to accept encoded frames of zero length. A zero length frame indicates to the decoder that one or more frames have been completely lost. This will mark the last decoded reference buffer as corrupted. The data pointer can be NULL if the length is zero. Change-Id: Ic5902c785a281c6e05329deea958554b7a6c75ce

2011-01-07CQ ModePaul Wilkins
The merge includes hooks to for CQ mode and other code changes merged from the test branch. CQ mode attempts to maintain a more stable quantizer within a clip whilst also trying to adhere to a guidline maximum bitrate. The existing target data rate parameter is used to specify the guideline maximum bitrate. A new parameter allows the user to specify a target CQ level. For normal (non kf/gf/arf) frames, the quantizer will not drop BELOW the user specified value (0-63). However, in some cases the encoder may choose to impose a target CQ that is above that specified by the user, if it estimates that consistent use of the target value is not compatible with guideline maximum bitrate.

2010-12-17Add psnr/ssim tuning optionJohn Koleszar
Add a new encoder control, VP8E_SET_TUNING, to allow the application to inform the encoder that the material will benefit from certain tuning. Expose this control as the --tune option to vpxenc. The args helper is expanded to support enumerated arguments by name or value. Two tunings are provided by this patch, PSNR (default) and SSIM. Activity masking is made dependent on setting --tune=ssim, as the current implementation hurts speed (10%) and PSNR (2.7% avg, 10% peak) too much for it to be a default yet.

The control will indicate which of the reference frames that were updated by setting the 3 LSBs in the input int (pointer). Change-Id: Iac9db60dac414356c7ffa0b0fede88cb91e11bd7
