Instead of wrapping the whole subdirectory's CMakeLists in
a gigantic if block, we use if(NOT HAVE_FOO) + return()
This is tidier since it keeps the indentation generally consistent
across all CMakeLists files.
- Make the build matrix actually run as a matrix
- Add a few exclusion rules to turn off some of the
more esoteric cases.
- Install libav, to test that p3ffmpeg builds
- Don't do a makepanda build at all on this branch
- Simplify uses of Python
- Change indentation style; no indentation for nested lists
This fixes some cases where transitive libraries, as nominated
by a component library, were not being absorbed into a metalib,
due to the library actually not being defined yet. This makes the
logic a little more robust, first by explicitly requiring a metalib
definition to come after all component library definitions, and second
to assume a library "linked" to a component library is a non-component
if it isn't defined (yet).
This commit isn't technically quite right, since Interrogate should
use the definitions from COMPILE_DEFINITIONS but the module should
be built with INTERFACE_COMPILE_DEFINITIONS, but whatever. That can
be changed if it becomes a nuisance later on.
The rationale here is it's consistent with how CMake treats these
two properties.
This changes the target_link_libraries() declarations so they only
go directly to a component library if it's in the same metalib.
If it's outside of the metalib, the correct thing to do is link against
the metalib. CMake takes care of the transitive linking for us, so
there isn't actually any big change here.
I have no idea why this error happens, but it does not seem worth the effort to investigate further, so I'm just reverting the previous change to this file.
I am not sure why the definition of NULL was removed; it might have been by mistake, but in any case it broke code like this:
img = PNMImage(w, h, color_space=CS_srgb)
since it would not understand the default value (NULL) for the argument preceding color_space.
This distinction allows us to better support Python 3, since it will raise exceptions when trying to put arbitrary binary data in a str object.
This also adds some convenience functions for efficiently initializing a Datagram or PTA_uchar from a vector_uchar.
We need to support this because Ubuntu 14.04 ships with this
version, and has no "backports" option to bring in a newer version
(without use of a PPA or compiling it yourself).
We can consider raising the minimums again once Trusty is EOL.
Previously this would close and reopen the codec context;
that's entirely unnecessary, as all supported versions of
libavcodec support flushing the buffers instead.
This leverages libavcodec >= 57.37.100's new asynchronous API,
which both allows decoding in hardware and in a separate thread,
and in any case would free up more CPU time for Panda's app loop.
This also avoids use of the now-deprecated `avcodec_decode_audio4`
AVStream.codec is deprecated as of libavformat version 57.41.100,
so if this version is detected, we switch to AVStream.codecpar instead.
Note this also makes it necessary to construct and use our own codec
context - but doing that is a cleaner approach anyway.
