* lavc/qtrle: Use AV_PIX_FMT_PAL8 for 1-bit videoMats Peterson2016-01-04
| | | | | | | | | | | | | | | | | | | | | | This commit fixes the lack of palettized display of 1-bit video in the qtrle decoder. It is related to my commit of lavf/qtpalette, which added 1-bit video to the "palettized video" category. As far as I can see, everything works fine, but comments are of course welcome. Below are links to sample files, which should now be displayed properly with bluish colors, but which were previously displayed in black & white.

| * dca: change the core to work with integer coefficients.Alexandra Hájková2015-12-23
| | | | | | | | | | | | | | | | | | | | | | | | The DCA core decoder converts integer coefficients read from the bitstream to floats just after reading them (along with dequantization). All the other steps of the audio reconstruction are done with floats which makes the output for the DTS lossless extension (XLL) actually lossy. This patch changes the DCA core to work with integer coefficients until QMF. At this point the integer coefficients are converted to floats. The coefficients for the LFE channel (lfe_data) are not touched. This is the first step for the really lossless XLL decoding.

| * arm: add a cpu flag for the VFPv2 vector modeJanne Grunau2015-12-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The vector mode was deprecated in ARMv7-A/VFPv3 and various cpu implementations do not support it in hardware. Vector mode code will depending the OS either be emulated in software or result in an illegal instruction on cpus which does not support it. This was not really problem in practice since NEON implementations of the same functions are preferred. It will however become a problem for checkasm which tests every cpu flag separately. Since this is a cpu feature newer cpu do not support anymore the behaviour of this flag differs from the other flags. It can be only activated by runtime cpu feature selection.

* | lavf/srtdec: rewrite parsing logicClément Bœsch2016-01-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes Ticket #5032 The samples in Ticket #5032 is using \r\r\n as line breaks. Since we already are handling \r, or \n, or \r\n as line breaks, \r\n\n will be considered as a double line breaks. This is an issue because ff_subtitles_read_text_chunk() will as a result stop extracting a chunk after just one line. So instead of parsing the SRT by "chunks" (which means splitting every double LB), this new parser is detecting timing lines, and split the events on this basis. While this sounds safe and simple, it needs to take into account the event number preceding the timing line while handling situations such as: - event number starting at 0 or actually any number instead of 1 - event numbers not being ordered at all - event number being followed by text garbage (this really happened, see Ticket #4898) - event payload containing one or multiple number (a protagonist saying a count-down, a date or whatever) which could be confused with a chapter number - event number being empty (see Ticket #2167) - all kind of weird line breaks can appear randomly like wild pokémons - untrustable line breaks (Ticket #5032) The sample madness.srt tries to sum up most of this into one sample, ticket5032-rrn.srt is the file containing \r\r\n line breaks. and empty-events-2167.srt contains empty events.

| | | | | | | | | | | | | | | | | | | | | | | | | | When the interpolated value is divided by the sum of weights, no rounding is done, which means the value is truncated. This results in a slight bias towards dark green in the interpolated area. Rounding properly removes the bias. I measured this change to reduce the interpolation error by 1 to 2 % on average on a number of sample input and logo area combinations.

* | AAC encoder: improve SF range utilizationClaudio Freire2015-12-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch does 4 things, all of which interact and thus it woudln't be possible to commit them separately without causing either quality regressions or assertion failures. Fate comparison targets don't all reflect improvements in quality, yet listening tests show substantially improved quality and stability. 1. Increase SF range utilization. The spec requires SF delta values to be constrained within the range -60..60. The previous code was applying that range to the whole SF array and not only the deltas of consecutive values, because doing so requires smarter code: zeroing or otherwise skipping a band may invalidate lots of SF choices. This patch implements that logic to allow the coders to utilize the full dynamic range of scalefactors, increasing quality quite considerably, and fixing delta-SF-related assertion failures, since now the limitation is enforced rather than asserted. 2. PNS tweaks The previous modification makes big improvements in twoloop's efficiency, and every time that happens PNS logic needs to be tweaked accordingly to avoid it from stepping all over twoloop's decisions. This patch includes modifications of the sort. 3. Account for lowpass cutoff during PSY analysis The closer PSY's allocation is to final allocation the better the quality is, and given these modifications, twoloop is now very efficient at avoiding holes. Thus, to compute accurate thresholds, PSY needs to account for the lowpass applied implicitly during twoloop (by zeroing high bands). This patch makes twoloop set the cutoff in psymodel's context the first time it runs, and makes PSY account for it during threshold computation, making PE and threshold computations closer to the final allocation and thus achieving better subjective quality. 4. Tweaks to RC lambda tracking loop in relation to PNS Without this tweak some corner cases cause quality regressions. Basically, lambda needs to react faster to overall bitrate efficiency changes since now PNS can be quite successful in enforcing maximum bitrates, when PSY allocates too many bits to the lower bands, suppressing the signals RC logic uses to lower lambda in those cases and causing aggressive PNS. This tweak makes PNS much less aggressive, though it can still use some further tweaks. Also update MIPS specializations and adjust fuzz Also in lavc/mips/aacpsy_mips.h: remove trailing whitespace
* | avformat/mp3dec: prefer "fast_seek" to TOC seek for CBR files.Chris Cunningham2015-12-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "Fast seek" uses linear interpolation to find the position of the requested seek time. For CBR this is more direct than using the mp3 TOC and bypassing the TOC avoids problems with TOC precision. (see https://crbug.com/545914#c13) For VBR, fast seek is not precise, so continue to prefer the TOC when available (the lesser of two evils). Also, some re-ordering of the logic in mp3_seek to simplify and give usetoc=1 precedence over fastseek flag. Signed-off-by: wm4 <nfxjfg@googlemail.com>
* | AAC encoder: make pe.min a local minimumClaudio Freire2015-11-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | As noted in a comment, pe.min in the reference encoder is centered around current pe. The bit reservoir algo needs pe.min to be a local minimum, because it can only account for local PE variations. If it's set to a global minimum as was being done, bit reservoir logic doesn't work as efficiently. This patch tries to forget old minimums and converge to a local minimum without losing the stability of the previous solution. Listening tests until now suggest this solves numerous RC issues.
