* test: make tests part of the mpv binarywm42019-11-081-6/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Until now, each .c file in test/ was built as separate, self-contained binary. Each binary could be run to execute the tests it contained. Change this and make them part of the normal mpv binary. Now the tests have to be invoked via the --unittest option. Do this for two reasons: - Tests now run within a "properly" initialized mpv instance, so all services are available. - Possibly simplifying the situation for future build systems. The first point is the main motivation. The mpv code is entangled with mp_log and the option system. It feels like a bad idea to duplicate some of the initialization of this just so you can call code using them. I'm also getting rid of cmocka. There wouldn't be any problem to keep it (it's a perfectly sane set of helpers), but NIH calls. I would have had to aggregate all tests into a CMUnitTest list, and I don't see how I'd get different types of entry points easily. Probably easily solvable, but since we made only pretty basic use of this library, NIH-ing this is actually easier (I needed a list of tests with custom metadata anyway, so all what was left was reimplement the assert_* helpers). Unit tests now don't output anything, and if they fail, they'll simply crash and leave a message that typically requires inspecting the test code to figure out what went wrong (and probably editing the test code to get more information). I even merged the various test functions into single ones. Sucks, but here you go. chmap_sel.c is merged into chmap.c, because I didn't see the point of this being separate. json.c drops the print_message() to go along with the new silent-by-default idea, also there's a memory leak fix unrelated to the rest of this commit. The new code is enabled with --enable-tests (--enable-test goes away). Due to waf's option parser, --enable-test still works, because it's a unique prefix to --enable-tests.
* test: fix cmocka assert_float_equal shadowing warningswm42019-09-211-3/+0
| | | | | | | | | Just use cmocka's function. It takes an epsilon argument, which we now provide directly. There's no assert_double_equal() in cmocka (and the float variant actually forces a conversion to the float type), but fortunately we didn't use it.

* vo_opengl: add gamma-auto optionStefano Pigozzi2015-03-041-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | This automatically sets the gamma option depending on lighting conditions measured from the computer's ambient light sensor. sRGB – arguably the “sibling” to BT.709 for still images – has a reference viewing environment defined in its specification (IEC 61966-2-1:1999, see http://www.color.org/chardata/rgb/srgb.xalter). According to this data, the assumed ambient illuminance is 64 lux. This is the illuminance where the gamma that results from ICC color management is correct. On the other hand, BT.1886 formalizes that the gamma level for dim environments to be 2.40, and Apple resources (WWDC12: 2012 Session 523: Best practices for color management) define the BT.1886 dim at 16 lux. So the logic we apply is: * >= 64lux -> 1.961 gamma * =< 16lux -> 2.400 gamma * 16lux < x < 64lux -> logaritmic rescale of lux to gamma. The human perception of illuminance roughly follows a logaritmic scale of lux [1]. [1]: https://msdn.microsoft.com/en-us/library/windows/desktop/dd319008%28v=vs.85%29.aspx
* chmap_sel: add multichannel fallback heuristicStefano Pigozzi2014-12-291-0/+11
Instead of just failing during channel map selection, try to select a close layout that makes most sense and upmix/downmix to that instead of failing AO initialization. The heuristic is rather simple, and uses the following steps: 1) If mono is required always prefer stereo to a multichannel upmix. 2) Search for an upmix that is an exact superset of the required channel map. 3) Search for a downmix that is the exact subset of the required channel map. 4) Search for either an upmix or downmix that is the closest (minimum difference of channels) to the required channel map.
