test: add dumping of img_format metadata This is fragile enough that it warrants getting "monitored". This takes the commented test program code from img_format.c, makes it output to a text file, and then compares it to a "ref" file stored in git. Originally, I wanted to do the comparison etc. in a shell or Python script. But why not do it in C. So mpv calls /usr/bin/diff as a sub-process now. This test will start producing different output if FFmpeg adds new pixel formats or pixel format flags, or if mpv adds new IMGFMT (either aliases to FFmpeg formats or own formats). That is unavoidable, and requires manual inspection of the results, and then updating the ref file. The changes in the non-test code are to guarantee that the format ID conversion functions only translate between valid IDs.

test: add tests for zimg RGB repacking This tests the RGB repacker code in zimg, which deserves to be tested because it's tricky and there will be more formats. scale_test.c contains some code that can be used to test any scaler. Or at least that would be great; currently it can only test repacking of some byte-aligned-component RGB formats. It should be called repack_test.c, but I'm too lazy to change the filename now. The idea is that libswscale is used to cross-check the conversions performed by the zimg wrapper. This is why it's "OK" that scale_test.c does libswscale calls. scale_sws.c is the equivalent to scale_zimg.c, and is of course worthless (because it tests libswscale by comparing the results with libswscale), but still might help with finding bugs in scale_test.c. This borrows a sorted list of image formats from test/img_format.c, for the same reason that file sorts them. There's a slight possibility that this can be used to test vo_gpu.c too some times in the future.

video: clean up some imgfmt related stuff Remove the vaguely defined plane_bits and component_bits fields from struct mp_imgfmt_desc. Add weird replacements for existing uses.

As a compromise, split mp_image_pixel_ptr() into 2 functions, because I think it's a bad idea to implicitly round, but for some callers being slightly less strict is convenient. This shouldn't really change anything. In fact, it's a 100% useless change. I'm just cleaning up what I started almost 8 years ago (see commit 00653a3eb052). With this I've decided to keep mp_imgfmt_desc, just removing the weird parts, and keeping the saner parts.

video: add pixel component location metadata I thought I'd probably want something like this, so the hardcoded stuff in repack.c can be removed eventually. Of course this has no purpose at all, and will not have any. (For now, this provides only metadata, and nothing uses it, apart from the "test" that dumps it as text.) This adds full support for AV_PIX_FMT_UYYVYY411 (probably out of spite, because the format is 100% useless). Support for some mpv-only formats is missing, ironically. The code goes through _lengths_ to try to make sense out of the FFmpeg AVPixFmtDescriptor data. Which is even more amazing that the new metadata basically mirrors pixdesc, and just adds to it. Considering code complexity and speed issues (it takes time to crunch through all this shit all the time), and especially the fact that pixdesc is very _incomplete_, it would probably better to have our own table to all formats. But then we'd not scramble every time FFmpeg adds a new format, which would be annoying. On the other hand, by using pixdesc, we get the excitement to see whether this code will work, or break everything in catastrophic ways. The data structure still sucks a lot. Maybe I'll redo it again. The text dump is weirdly differently formatted than the C struct - because I'm not happy with the representation. Maybe I'll redo it all over again. In summary: this commit does nothing.

On the other hand, by using pixdesc, we get the excitement to see whether this code will work, or break everything in catastrophic ways. The data structure still sucks a lot. Maybe I'll redo it again. The text dump is weirdly differently formatted than the C struct - because I'm not happy with the representation. Maybe I'll redo it all over again. In summary: this commit does nothing.

video: shuffle imgfmt metadata code around I guess I decided to stuff it all into mp_imgfmt_desc (the "old" struct). This is probably a mistake. At first I was afraid that this struct would get too fat (probably justified, and hereby happened), but on the other hand mp_imgfmt_get_desc() (which builds the struct) calls the former mp_imgfmt_get_layout(), and the separation doesn't make too much sense anyway. Just merge them. Still, try to keep out the extra info for packed YUV bullshit. I think the result is OK, and there's as much information as there was before. The test output changes a little. There's no independent bits[] array anymore, so formats which did not previously have set this now show it. (These formats are mpv-only and are still missing the metadata. To be added later). Also, the output for the cursed packed formats changes.

video: add pixel component location metadata I thought I'd probably want something like this, so the hardcoded stuff in repack.c can be removed eventually. Of course this has no purpose at all, and will not have any. (For now, this provides only metadata, and nothing uses it, apart from the "test" that dumps it as text.) This adds full support for AV_PIX_FMT_UYYVYY411 (probably out of spite, because the format is 100% useless). Support for some mpv-only formats is missing, ironically. The code goes through _lengths_ to try to make sense out of the FFmpeg AVPixFmtDescriptor data. Which is even more amazing that the new metadata basically mirrors pixdesc, and just adds to it. Considering code complexity and speed issues (it takes time to crunch through all this shit all the time), and especially the fact that pixdesc is very _incomplete_, it would probably better to have our own table to all formats. But then we'd not scramble every time FFmpeg adds a new format, which would be annoying. On the other hand, by using pixdesc, we get the excitement to see whether this code will work, or break everything in catastrophic ways. The data structure still sucks a lot. Maybe I'll redo it again. The text dump is weirdly differently formatted than the C struct - because I'm not happy with the representation. Maybe I'll redo it all over again.

test: add dumping of img_format metadata This is fragile enough that it warrants getting "monitored". This takes the commented test program code from img_format.c, makes it output to a text file, and then compares it to a "ref" file stored in git. Originally, I wanted to do the comparison etc. in a shell or Python script. But why not do it in C. So mpv calls /usr/bin/diff as a sub-process now. This test will start producing different output if FFmpeg adds new pixel formats or pixel format flags, or if mpv adds new IMGFMT (either aliases to FFmpeg formats or own formats). That is unavoidable, and requires manual inspection of the results, and then updating the ref file. The changes in the non-test code are to guarantee that the format ID conversion functions only translate between valid IDs.

video: change chroma_w/chroma_h fields to use shift instead of size When I added mp_regular_imgfmt, I made the chroma subsampling use the actual chroma division factor, instead of a shift (log2 of the actual value). I had some ideas about how this was (probably?) more intuitive and general. But nothing ever uses non-power of 2 subsampling (except jpeg in rare cases apparently, because the world is a bad place). Change the fields back to use shifts and rename them to avoid mistakes.
