* libkvazaar: Set frame rate as a rational numberArttu Ylä-Outinen2016-01-20
| | | | | | | | | | | Updates libkvazaar to pass the exact frame rate to Kvazaar by setting the numerator and denominator separately instead of a single floating point number. The exact frame rate is needed for writing timing info to the bitstream. Requires Kvazaar version 0.8.1. Signed-off-by: Arttu Ylä-Outinen <arttu.yla-outinen@tut.fi>

* | AAC encoder: use signed coeffs when measuring IS energyClaudio Freire2016-01-17

* | AAC encoder: enforce SF delta in PNS and IS SFsClaudio Freire2016-01-17
| | | | | | | | | | | | | | | | | | Make sure to properly enforce maximum scalefactor delta in PNS and I/S, not as an absolute range but relative to the previous and first scalefactor, the latter important since PNS uses an implicit inicial scalefactor derived from the global gain, and encoded in a different way, which makes a big difference in the allowed range.

* | lavc/ccaption_dec: clear all unused rows during rollupAman Gupta2016-01-14
| | | | | | | | | | | | Sometimes rollup captions can move around the screen. This fixes "ghost" captions from below the current rollup area from continuing to be captured when a rollup moves higher up on the screen.

* | lavc/ccaption_dec: implement real_time optionAman Gupta2016-01-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This new mode is useful for realtime decoding of closed captions so they can be display along with mpeg2 frames. Closed caption streams contain two major types of captions: - POPON captions, which are buffered off-screen and displayed only after EOC (end of caption, aka display buffer) - PAINTON/ROLLUP captions, which are written to the display as soon as they arrive. In a typical real-time eia608 decoder, commands like EOC (end of caption; display buffer), EDM (erase display memory) and EBM (erase buffered memory) perform their expected functions as soon as the commands are processed. This is implemented in the real_time branches added in this commit. Before this commit, and in the !real_time branches after this commit, the decoder cleverly implements its own version of the decoder which is specifically geared towards buffered decoding. It does so by actively ignoring commands like EBM (erase buffered memory), and then re-using the non-display buffer to hold the previous caption while the new one is received. This is the opposite of the real-time decoder, which uses the non-display buffer to hold the new caption while the display buffer is still showing the current caption. In addition to ignoring EBM, the buffered decoder also has custom implementations for EDM and EOC. An EDM (erase display memory) command flushes the existing contents before clearing the screen, and EOC similarly always flushes the active buffer (the previous subtitle) before flipping buffers.

* | avcodec/aacenc_is: replace pow(x, 0.75) by x/sqrtf(sqrtf(x))Claudio Freire2016-01-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is quite an accurate approximation; testing shows ~ 2ulp error in the floating point result. Tested with FATE. Alternatively, if one wants "full accuracy", one can use powf, or sqrt instead of sqrtf. With powf, one gets 1 ulp error (theoretically should be 0, as 0.75 is exactly representable) on GNU libm, with sqrt, 0 ulp error.

* | AAC encoder: encode out-of-phase I/S efficientlyClaudio Freire2016-01-13
| | | | | | | | | | | | | | | | | | | | | | Use the ability to invert phase with ms_mask instead of changing the codebook when possible, to avoid having to switch codebooks if some bands are INTENSTY_BT and others are INTENSITY_BT2, since usually a set ms_mask uses less bits that a codebook change. While it may not always be a win (ie: if it causes an ms_mask bitmap to be sent when it wouldn't have been otherwise), it's unlikely since the ms_mask bitmap will almost always be there already for M/S itself.
* | AAC encoder: fix I/S relative error evaluationClaudio Freire2016-01-13
| | | | | | | | | | | | | | The relative error between two encoding strategies is the simple difference of rate-distortion values, and not the absolute difference. An absolute measure would allow worsening of the quantization error as well as improving.
* | AAC encoder: various fixes in M/S codingClaudio Freire2016-01-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Fix sf_idx and band_type addressing to address only the first subwindow in the group (others could hold garbage values) 2. Don't step on ms_mask when is_mask is set. I/S selection already sets the ms_mask properly and shouldn't be overridden. 3. Use mid/sid cb/sf when computing coding error, as should be since those are the cb/sfs that will eventually be set. 4. Fix distortion computation on multi-subwindow groups (was subtracting the bits terms multiple times) 5. Clear ms_mask when one side uses PNS and the other doesn't. When using PNS, ms_mask signals correlated noise, which can be detected just like regular M/S detection, so we don't skip noise bands, but when only one side uses PNS setting the flag can confuse some encoders, so avoid that.
