2011-11-11avoid resetting framerate during vpx_codec_enc_config_set()John Koleszar
The calculated frame_rate is a state variable in the codec, and shouldn't be maintained in the configuration struct. Move it to the main part of cpi so that it isn't clobbered when the configuration struct is updated. The initial framerate estimate is moved from the vp8_cx_iface.c wrapper into the body of init_config() in onyx_if.c, so that it is only called once and not reset on every call to vp8_change_config().

2011-10-20Fix: check cx_data buffer prior to writeJames Berry
check to make sure that cx_data buffer has enough room before writting to it, prior behavior did not which could result in a crash. Change-Id: I3fab6f2bc4a96d7c675ea81acd39ece121738b28
2011-10-11Added rate-targeted temporal scalabilityAdrian Grange
Added the ability to create rate-targeted, temporally scalable, VP8 compatible bitstreams. The application vp8_scalable_patterns.c demonstrates how to use this capability. Users can create output bitstreams containing upto 5 temporally separable streams encoded as a single VP8 bitstream.

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.

2011-06-28New 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.

2011-04-25Merge "Change rc undershoot/overshoot semantics"John Koleszar
2011-04-25Add rc_max_intra_bitrate_pct controlJohn Koleszar
Adds a control to limit the maximum size of a keyframe, as a function of the per-frame bitrate.

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.

2011-03-10Removed firstpass motion mapAdrian Grange
The firstpass motion map consists of an 8-bit flag for each MB indicating how strongly the firstpass code believes it should be filtered during the second pass ARNR filtering. For long or large format material the motion map can become extremely large and hamper the operation of the encoding process. This change removes the motion map altogether, leaving the second pass to rely on the magnitude of the motion compensated error to determine the filter weight to use for the MB during ARNR filtering. Tests on the derf set indicate that the effect of this change is neutral, with some small wins and losses. The motion map has therefore been removed based on a cost/benefit evaluation.

2011-01-17Fix CQ range and experimental KF sizing changes.Paul Wilkins
The CQ level was not using the q_trans[] array to convert to a 0-127 range as per min and maxq Experimental change to try and match the reconstruction error for forced key frames approximately to that of the previous frame by means of the recode loop. Though this may cause extra recodes and the recode behavior has not been optimized, it can only happen on forced key frames. Change-Id: I1f7e42d526f1b1cb556dd461eff1a692bd1b5b2f
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.

2010-10-21Move firstpass motion map to stats packetJohn Koleszar
The first implementation of the firstpass motion map for motion compensated temporal filtering created a file, fpmotionmap.stt, in the current working directory. This was not safe for multiple encoder instances. This patch merges this data into the first pass stats packet interface, so that it is handled like the other (numerical) firstpass stats. The new stats packet is defined as follows: Numerical Stats (16 doubles) -- 128 bytes Motion Map -- 1 byte / Macroblock Padding -- to align packet to 8 bytes The fpmotionmap.stt file can still be generated for debugging purposes in the same way that the textual version of the stats are available (defining OUTPUT_FPF in firstpass.c) Change-Id: I083ffbfd95e7d6a42bb4039ba0e81f678c8183ca

2010-09-23Add getter functions for the interface data symbolsJohn Koleszar
Having these symbols be available as functions rather than data is occasionally more convenient. Implemented this way rather than a get-codec-by-id style to avoid creating a link-time dependency between the encoder and the decoder. Fixes issue #169 Change-Id: I319f281277033a5e7e3ee3b092b9a87cce2f463d
2010-09-20Add high limit check for unsigned parametersGuillermo Ballester Valor
The patch related with issue #55 (5a72620) fixed some warnings, but the fix was not optimal. It actually was a trick to confuse compiler rather than a fix. This patch fixes it by creating a new macro used when needed just a high limit check for an unsigned. Change-Id: I94b322e0f7fb07604b3b1df1f9321185f48cfcb5

2010-09-02encoder: remove postproc dependencyJames Zern
Remove the dependency on postproc.c for the encoder in general, the only unchecked need for it is when CONFIG_PSNR is enabled. All other cases are already wrapped in CONFIG_POSTPROC. In the CONFIG_PSNR case the file will still be included. Additionally, when VP8_SET_POSTPROC is used with the encoder when post processing has been disabled an error will be returned. This addresses issue #153. Change-Id: Ia6dfe20167f7077734a6058cbd1d794550346089

This is to accommodate output packets for both compressed data and psnr stats. For each frame, there are at least one packet for compressed data and one for psnr stats.
