Compiling with libswscale isn't really optional if you want to play most video files, but if you know what you are doing and all your videos already have a supported pixel formats, it is now possible.
Fixes#711
The symbols moved aren't used in any headers, so they don't
have to be in the installed dtool_config.h. Removing them
keeps the recompiling to a minimum when an optional feature
is toggled.
This changes includes so that local includes are consistently
#include "localFile.h"
while system and third-party includes are consistently
#include <systemFile.h>
This commit mostly converts the former to the latter; the two
exceptions are in android_main.cxx and fmodAudioSound.h, where
the reverse was necessary.
Instead, let's use a PKG::PKGNAME interface library, which simplifies
the linking and also allows us to use imported libraries from
find_package in the future.
This is inefficient because it induces an unnecessary ref()/unref() pair when we just need to move the pointer out of the function. Thanks to 23128e4695, we can now move between related pointer types, making the .p() hack unnecessary.
Newer versions of FFmpeg deprecate returning 0 to indicate
EOF, and instead request use of AVERROR_EOF.
The oldest supported versions of FFmpeg/libav will treat any
error code the same as returning 0.
Fixes#315
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.
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.
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`
