2011-03-08Write SSSE3 sub-pixel filter functionYunqing Wang
1. Process 16 pixels at one time instead of 8. 2. Add check for both xoffset =0 and yoffset=0, which happens during motion search. This change gave encoder 1%~3% performance gain. Change-Id: Idaa39506b48f4f8b2fbbeb45aae8226fa32afb3e
2011-03-08Fix a multi-line format-string warning.Ralph Giles
GCC 4.5 and 4.6 both issue a warning about the multi-line format string introduced in bc9c30a0, which also changed the whitespace in the associated stt file by line-wrapping the long format string. Instead, use multiple string constants, which the compiler will concatenate. This maintains the original formatting, but remains legible within the standard line length.

* changes: Improved key frame detection. Improved KF insertion after fades to still.
2011-03-07correct zbin boost for splitmv modeJohn Koleszar
Disable zbin boost in SPLITMV mode as intended. Was incorrectly looking at vp8_ref_frame_order instead of vp8_mode_order when comparing against SPLITMV. This condition should have always been false, as SPLITMV is not in the range of valid reference frames. Change-Id: I0408cc7595eff68f00efef6d008e79f5b60d14bf
2011-03-07Improved key frame detection.Paul Wilkins
In some cases where clips have been encoded with borders (eg. some wide-screen content where there is a border top and bottom and slide shows containing portrait format photographs (border left and right)) key frames were not being correctly detected. The new code looks to measure cases where a portion of the image can be coded equally easily using intra or inter modes and where the resulting error score is also very low. These "neutral" areas are then discounted in the key frame detection code. Change-Id: I00c3e8230772b8213cdc08020e1990cf83b780d8
2011-03-07Improved KF insertion after fades to still.Paul Wilkins
This code extends what was previously done for GFs, to pick cases where insertion of a key frame after a fade (or other transition or complex motion) followed by a still section, will be beneficial and will reduce the number of forced key frames. Change-Id: If8bca00457f0d5f83dc3318a587f61c17d90f135

2011-03-02Fix drastic undershoot in long form contentJohn Koleszar
When the modified_error_left accumulator exceeds INT_MAX, an incorrect cast to int resulted in a negative value, causing the rate control to allocate no bits to that keyframe group, leading to severe undershoot and subsequent poor quality. This error was exposed by the recent change to the rolling target and actual spend accumulators in commit 305be4e4 which fixed them to actually calculate the average value rather than be re-initialized on every frame to the average per-frame bitrate. When this bug was triggered, the target bitrate could be 0, so the rolling target becomes small, which causes the undershoot. The code prior to 305be4e4 did not exhibit this behavior because the rolling target was always set to a reasonable value and was independent of the actual target bitrate. With this patch, the actual target bitrate is calculated correctly, and the rate control tracks as expected. This cast was likely added to silence a compiler warning on a comparison between a double (modified_error_left) and an int (0). Instead, this patch removes the cast and changes the comparison to be against 0.0, which should prevent the warning from reoccuring. This fixes issue #289. Special thanks to gnafu for his efforts in reporting and debugging this fix. Change-Id: Ie5cc1a7b516c578a76c3a50c892a6f04a11621fe

2011-02-24Overflow of frame error accumulators.Paul Wilkins
This fixes an overflow problem in the frame error accumulators. The overflow condition is extreme but did trigger when Frank B. coded some high motion interlaced HD content. The observed effect was a catastrophic breakdown of the rate control leading to massive undershoot and poor bit allocation. All the error values should really be unsigned but I will look at this separately. Change-Id: I9745f5c5ca2783620426b66b568b2088b579151f
