2015-06-18Add dynamic resize logic for 1 pass CBR.Marco
Decision to scale down/up is based on buffer state and average QP over previous time window. Limit the total amount of down-scaling to be at most one scale down for now. Reset certain quantities after resize (buffer level, cyclic refresh, rate correction factor). Feature is enable via the setting rc_resize_allowed = 1.

2015-06-09Enable more split modes for animated content.Paul Wilkins
For content that is identified as likely to contain some animation or graphics content, increase the availability of split modes for good quality speeds 1-3. On a problem test animation clip this improves metrics results by about 0.25 db and makes a noticeable difference visually. It also causes a small drop in file size (~0.5%) but a rise in encode time of about 5-6% at speed 2. For more normal content it should have no effect.

2015-05-20Fast feedback of bits on undershoot.paulwilkins
This patch provides a partial rapid feedback of bits resulting from extreme undershoot. Some improvement on some problem animated material but in its current form only a small impact on the metrics results of our standard test sets. Change-Id: Ie03036ea8123bc2553437cb8c8c9e7a9fc5dac5d
2015-05-20Fix issues with mixed ARF and GF groups.paulwilkins
This patch addresses two issues that can occur when the encoder chooses to use a mixture of ARF and GF groups. The first issue relates to a failure to reset the "ARF active" flag correctly when transitioning from coding ARF groups to coding GF groups. This caused some golden frames to be encoded with an incorrect bit rate target as if they were ARF overlay frames. The second issue relates to the encoding of a single short GF group just before a key frame. Where the last group before a key frame is an ARF group we expect the final frame before the key frame to be an low data rate overlay frame. However, when the last group is a GF group, the final frame before the key frame should be a normal frame with a normal bit allocation. This issue had the potential to cause a single poorly coded frame just before a key frame. If that key frame were a forced key frame rather than a real scene cut, this might cause pulsing.

2015-05-14Revert "Skip the last frame update for some frame repeats."paulwilkins
Testing on another rate control patch reveals that in some situations, where the encoder is flipping in and out of arf mode, we get an encoder decoder mismatch. Whilst it is still not clear why, skipping the last buffer update seems to trigger the problem. Until I can establish why, or if there is another underlying cause, I am reverting this change. This reverts commit e5112b3ae3352c4c55fb31235305f3f80f4b8f7e. Change-Id: I315c5200414de89458015823344b7367e9dd75ba

2015-05-12Protect new metric computation with use_highbitdepth flagYaowu Xu
The computation of new metrics is not supported yet in highbitdepth mode. This commit adds protection to make sure the computation is done only when highbitdepth is not on. This protection shall be revised when support of highbitdpeth computation is added. This resolves the encoder crash when configured with both --enable-internal-stats --enable-vp9-highbitdepth Change-Id: Id9f4bcc4fa26d9ca0e9eabade83f3f88a5b212e6

2015-05-08Skip the last frame update for some frame repeats.paulwilkins
Where a frame appears to be a repeat of an earlier frame or frame buffer, but the first pass code does not anticipate this (usually because it is matching the GF or ARF buffer not the last frame buffer), do not update the last frame buffer. This helps ensure that the content of the last frame buffer is kept "different" where possible, and not updated to match the GF or ARF. This is particularly helpful in some animated sequences where there are groups of repeating frames. Here it has quite a big impact. However, in most of our standard test clips it has little or no impact. Change-Id: I77332ee1a69f9ffc0c6080bfeb811c43fd8828e6
