* avutil/pixdesc: Add av_chroma_location_(enum_to_pos|pos_to_enum)Andreas Rheinhardt2022-09-261-0/+22
| | | | | | | They are intended as replacements for avcodec_enum_to_chroma_pos() and avcodec_chroma_pos_to_enum(). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* lavu/pixdesc: favour formats where depth and subsampling exactly matchPhilip Langdale2022-09-171-6/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since introducing the various packed formats used by VAAPI (and p012), we've noticed that there's actually a gap in how av_find_best_pix_fmt_of_2 works. It doesn't actually assign any value to having the same bit depth as the source format, when comparing against formats with a higher bit depth. This usually doesn't matter, because av_get_padded_bits_per_pixel() will account for it. However, as many of these formats use padding internally, we find that av_get_padded_bits_per_pixel() actually returns the same value for the 10 bit, 12 bit, 16 bit flavours, etc. In these tied situations, we end up just picking the first of the two provided formats, even if the second one should be preferred because it matches the actual bit depth. This bug already existed if you tried to compare yuv420p10 against p016 and p010, for example, but it simply hadn't come up before so we never noticed. But now, we actually got a situation in the VAAPI VP9 decoder where it offers both p010 and p012 because Profile 3 could be either depth and ends up picking p012 for 10 bit content due to the ordering of the testing. In addition, in the process of testing the fix, I realised we have the same gap when it comes to chroma subsampling - we do not favour a format that has exactly the same subsampling vs one with less subsampling when all else is equal. To fix this, I'm introducing a small score penalty if the bit depth or subsampling doesn't exactly match the source format. This will break the tie in favour of the format with the exact match, but not offset any of the other scoring penalties we already have. I have added a set of tests around these formats which will fail without this fix.

* avutil/pixdesc: deprecate AV_PIX_FMT_FLAG_PSEUDOPALwm42018-04-031-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PSEUDOPAL pixel formats are not paletted, but carried a palette with the intention of allowing code to treat unpaletted formats as paletted. The palette simply mapped the byte values to the resulting RGB values, making it some sort of LUT for RGB conversion. It was used for 1 byte formats only: RGB4_BYTE, BGR4_BYTE, RGB8, BGR8, GRAY8. The first 4 are awfully obscure, used only by some ancient bitmap formats. The last one, GRAY8, is more common, but its treatment is grossly incorrect. It considers full range GRAY8 only, so GRAY8 coming from typical Y video planes was not mapped to the correct RGB values. This cannot be fixed, because AVFrame.color_range can be freely changed at runtime, and there is nothing to ensure the pseudo palette is updated. Also, nothing actually used the PSEUDOPAL palette data, except xwdenc (trivially changed in the previous commit). All other code had to treat it as a special case, just to ignore or to propagate palette data. In conclusion, this was just a very strange old mechnaism that has no real justification to exist anymore (although it may have been nice and useful in the past). Now it's an artifact that makes the API harder to use: API users who allocate their own pixel data have to be aware that they need to allocate the palette, or FFmpeg will crash on them in _some_ situations. On top of this, there was no API to allocate the pseuo palette outside of av_frame_get_buffer(). This patch not only deprecates AV_PIX_FMT_FLAG_PSEUDOPAL, but also makes the pseudo palette optional. Nothing accesses it anymore, though if it's set, it's propagated. It's still allocated and initialized for compatibility with API users that rely on this feature. But new API users do not need to allocate it. This was an explicit goal of this patch. Most changes replace AV_PIX_FMT_FLAG_PSEUDOPAL with FF_PSEUDOPAL. I first tried #ifdefing all code, but it was a mess. The FF_PSEUDOPAL macro reduces the mess, and still allows defining FF_API_PSEUDOPAL to 0. Passes FATE with FF_API_PSEUDOPAL enabled and disabled. In addition, FATE passes with FF_API_PSEUDOPAL set to 1, but with allocation functions manually changed to not allocating a palette.
