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().

2011-11-09Relocated idct/add calls for encoderScott LaVarnway
Call the idct/add after the tokenize. This is WIP with the goal of creating a common idct/add for the encoder and decoder. This move is necessary because the decoder's version of the idct clobbers qcoeff, which is used by the tokenize. Change-Id: I6b08d8e8397cd873647fa4fb9469884e3c876756

2011-11-07Added check to make sure maximum buffer size not exceededAdrian Grange
Added code to clip the buffer level to the maximum buffer size. Without this the buffer level would increase unchecked. This bug was found when encoding an essentially static scene at 2Mb/s. The encoder is unable to generate frames consistent with the high data-rate because Q bottoms out at Qmin. As frames generated are consistently undersized the buffer level increases and does not get checked against the maximum size specified by the user (or default).

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

2011-10-31Correct SPLITMV clampingJohn Koleszar
Prior to this fix, the clamping state of the last subblock partition dominated, whereas the correct behavior is to clamp if any partition needs clamping. This bug was introduced by v0.9.6-232-g6b25501 See also: [1]: http://code.google.com/p/webm/issues/detail?id=371 [2]: https://bugzilla.mozilla.org/show_bug.cgi?id=696390 Change-Id: I444db492b4c4f05f039c7da6f4216da8207dc138
2011-10-28added code to clear 2nd order block when appropriateYaowu Xu
It is discovered that in rare situations the 2nd order block may produce a few small magnitude coefficients that has no effect on reconstruction. The situations are a combination of low quantizer values (high quality) and low energy in residual signals (content dependent). This commit added code to detect such cases and reset the 2nd order block to all 0. Patch 1 to 4 used code to do all-zero-check on idct result buffer, and tests on derf set showed a consistent gain of .12%-.14% on all metrics.But due to a recent change Ie31d90b, the idct result buffer is not longer populated. So patch 5&6 use an alternative method to detect the situations. Tests on derf set now shows a consistent quality gain of .16%-.20%. As suggested by Jim, Patch 7&8 removed the condition of all first order block not having any coefficient, instead we reset 2nd order coefficients to all 0 if sum of absolute value of the coefficients is small. So it does slightly more than just detecting the oddity as discussed above, but tests on derf set now show a consistent gain of .20%-.23% on all metrics. It is worth noting here that this change does not have any effect on mid/high quantizer range, it only affects the quantizer value 18 or blow. Within this range, the change helps compression by up to 2.5% on clips in the derf set. Change-Id: I718e19cf59a4fc2462cb7070832759beb9f7e7dd
