* fate/aacenc: increase tolerance for ln-128k testLynne2022-11-24
| | | | | | | | | | | The encoder is sensitive to changes in precision, and its test target was a compromise. It was already close to failing on x87 FPUs. ff_mdct_init used double precision entirely from the scale to computing the MDCT exp tables. av_tx_init uses single-precision for the scale, with a small input change which was enough to tip the test into failing on x87 FPUs. Increase the fuzz factor in line with other AAC encoder tests to fix.

* dcaenc: convert to lavu/txLynne2022-11-06
| | | | | | The encoder is fixed point, and uses an MDCT only for analysis. Due to the slightly different rounding, the encoder makes a different decision, so the tests have to be adjusted as well.

* aacdec: convert to lavu/tx and support fixed-point 960-sample decodingLynne2022-11-06
| | | | | | | | | | | This patch replaces the transform used in AAC with lavu/tx and removes the limitation on only being able to decode 960-sample files with the float decoder. This commit also removes a whole bunch of unnecessary and slow lifting steps the decoder did to compensate for the poor accuracy of the old integer transformation code. Overall float decoder speedup on Zen 3 for 64kbps: 32%

* avcodec/svq1: fix interframe mean VLC symbolsPeter Ross2022-11-01
| | | | | | | | | | | | | | | | | | Fixes ticket #128. The SVQ1 interframe mean VLC symbols -128 and 128 are incorrectly swapped in our SVQ1 implementation, resulting in visible artifacts for some videos. This patch unswaps the order of these two symbols. The most noticable example of the artiacts caused by this error can be observed in https://trac.ffmpeg.org/attachment/ticket/128/svq1_set.7z '352_288_k_50.mov'. The artifacts are not observed when using the reference decoder (QuickTime 7.7.9 x86 binary). As a result of this patch, the reference data for the fate-svq1 test ($SAMPLES/svq1/marymary-shackles.mov) must be modified. For this file, our decoder output is now bitwise identical to the reference decoder. I have tested patch with various other samples and they are all now bitwise identical.
* avcodec/svq1enc: output ident string in extradata fieldPeter Ross2022-11-01

* ffmpeg: Add display_{rotation, hflip, vflip} optionsJan Ekström2022-10-19
| | | | | | | | | This enables overriding the rotation as well as horizontal/vertical flip state of a specific video stream on the input side. Additionally, switch the singular test that was utilizing the rotation metadata to instead override the input display rotation, thus leading to the same result.

* lavu/riscv: CPU flag for the Zbb extensionRémi Denis-Courmont2022-10-05
| | | | | | | | | | | | Unfortunately, it is common, and will remain so, that the Bit manipulations are not enabled at compilation time. This is an official policy for Debian ports in general (though they do not support RISC-V officially as of yet) to stick to the minimal target baseline, which does not include the B extension or even its Zbb subset. For inline helpers (CPOP, REV8), compiler builtins (CTZ, CLZ) or even plain C code (MIN, MAX, MINU, MAXU), run-time detection seems impractical. But at least it can work for the byte-swap DSP functions.

* avcodec/rl2: Remove wrong checkAndreas Rheinhardt2022-10-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This check is intended to be avoid buffer overflows, yet there are four problems with it: 1. It has an in-built off-by-one error: len == out_end - out is perfectly fine and nothing to worry about. This off-by-one error led to the pixel in the lower-right corner not being set properly for the back frame of the sample from the rl2 FATE-test. This pixel is copied to every frame which is the reason for the update to the reference file of said test. With this patch, the output of the decoder matches the output as captured from the reference decoder* (apart from the fact that said reference somehow lacks the top part of the frame (copied over from the background frame)). 2. Given that the stride of the buffer may be different from the width of the video (despite one pixel taking one byte), there is a second check lateron making the first check redundant (if one returns immediately; a simple break at the second check is not sufficient, because it only exits the inner loop). 3. The check is based around the assumption of the stride being positive (it has this in common with the other check which will be fixed in a future commit). 4. Even after fixing the off-by-one error, the check in question is still triggered by all the non-background frames in the FATE sample as well as by A1100100.RL2. In all these cases, they use len == 255 and val == 128. For videos with background frame this just means "copy from the background frame", which would be done anyway lateron.* Yet for videos without it copying it is necessary to avoid leaving uninitialized parts in the video. *: Available in https://samples.mplayerhq.hu/game-formats/voyeur-rl2/ **: Due to this, the code that copies the rest from the back frame is no longer executed for any of the samples available on the sample server. Given that these are only the files from the demo version of this game, I don't know whether this code is executed for any file in existence or not.

* lavu/cpu: CPU flags for the RISC-V Vector extensionRémi Denis-Courmont2022-09-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RVV defines a total of 12 different extensions, including: - 5 different instruction subsets: - Zve32x: 8-, 16- and 32-bit integers, - Zve32f: Zve32x plus single precision floats, - Zve64x: Zve32x plus 64-bit integers, - Zve64f: Zve32f plus Zve64x, - Zve64d: Zve64f plus double precision floats. - 6 different vector lengths: - Zvl32b (embedded only), - Zvl64b (embedded only), - Zvl128b, - Zvl256b, - Zvl512b, - Zvl1024b, - and the V extension proper: equivalent to Zve64f and Zvl128b. In total, there are 6 different possible sets of supported instructions (including the empty set), but for convenience we allocate one bit for each type sets: up-to-32-bit ints (RVV_I32), floats (RVV_F32), 64-bit ints (RVV_I64) and doubles (RVV_F64). Whence the vector size is needed, it can be retrieved by reading the unprivileged read-only vlenb CSR. This should probably be a separate helper macro if needed at a later point.
* lavu/cpu: detect RISC-V base extensionsRémi Denis-Courmont2022-09-27
| | | | | | | | | | This introduces compile-time and run-time CPU detection on RISC-V. In practice, I doubt that FFmpeg will ever see a RISC-V CPU without all of I, F and D extensions, and if it does, it probably won't have run-time detection. So the flags are essentially always set. But as things stand, checkasm wants them that way. Compare the ARMV8 flag on AArch64. We are nowhere near running short on CPU flag bits.
