* Add update_gpac.py
Add a Python script that partially automates updating GPAC to a newer
version.
* Update GPAC to version 1.0.1
Update the vendored version of GPAC to version 1.0.1.
* Add necessary GPAC header files
Add some GPAC header files that GPAC needs to compile.
* Define _GF_CONFIG_H_ to fix Linux build failing
gpac/configuration.h has a series of default configuration options for
various platforms, but it doesn't have a case for Linux and it results
in a compilation error if it encounters an unknown platform.
The settings in configuration.h don't appear to try to set any defaults
for Linux anyway, so we can disable all use of those configuration.h
settings by defining _GF_CONFIG_H_.
* Add some more necessary GPAC header files
Add a few more header files necessary to get GPAC to compile.
* Fix renamed and removed media types
Some mp4 media types ("clcp", "c608") were renamed by GPAC. "c708"
appears to have been removed, so we can just add the definition of that
to the top of mp4.c.
* Remove Remotery from updated GPAC
Remotery appears to be some code for profiling GPAC which we aren't
using, and including Remotery.c and Remotery.h ends up pulling in a lot
of files, so it's easier to just remove the include of Remotery.h and
the single use of it in os_divers.c
* Remove unused box definitions
Remove box definitions that we don't use from box_funcs.c in order to
avoid adding too many files from GPAC.
* Replace alloc function declarations with defines
Replace the GPAC wrappers around the malloc-style functions (gf_malloc,
gf_free, etc.) with defines that use the standard C versions of these
functions so that we can avoid including GPAC's alloc.c
* Remove WebVTT handling code in gf_isom_dump_srt_track
Remove the code that handles WebVTT in gf_isom_dump_srt_track to avoid
needing to pull in a lot of other files from GPAC.
gf_isom_dump_srt_track doesn't appear to be used by ccextractor directly
or indirectly (it's only called in gf_isom_text_dump which doesn't
appear to be called anywhere else) so it should be fine removing it.
* Disable use of Remotery and gzip on Linux
Use GPAC_DISABLE_REMOTERY and NO_GZIP to disable Remotery because we
aren't interested in profiling (see
5c0c9cf71e for more info) and gzip
compression through gzio.c respectively.
* Fix compilation errors in GPAC on linux
GPAC on linux after the update requires some threading functions and
dynamic loading functions in pthread and dl respectively.
* Add necessary files for GPAC to compile
Add several C and header files that GPAC needs to compile
* Disable Remotery and Gzip in all build systems
Disable Remotery and gzip (using the same method as
f49dc371b5) for:
- The linux build script (linux/build)
- The mac build script (mac/build.command)
- The mac makefile
- cmake
- bazel
- Visual Studio
* Add extra GPAC files to several build systems
Add the names of several GPAC files that were added in the update to the
linux and mac Makefiles and to the Windows Visual Studio project.
Adding these filenames isn't necessary for CMake, Bazel, or the linux or
mac build scripts because all of them compile all C files recursively in
the src/thirdparty/gpacmp4 directory instead of having an explicit list
of files to compile.
* Change NO_GZIP to GPAC_DISABLE_ZLIB in VS project
Instead of defining NO_GZIP to disable gzip support, define
GPAC_DISABLE_ZLIB, which does the same thing but also prevents the
compiler from trying to zlib.
* Avoid using GPAC's configuration.h completely
GPAC's configuration.h has a few problems with the defaults that it
sets:
- It defines GPAC_MEMORY_TRACKING on Windows, which switches to an
alternate implementation of malloc, meaning that we would have to pull
in alloc.c
- It causes compilation errors on Linux (see 9164c08979)
This disables using configuration.h by:
- Defining GPAC_HAVE_CONFIG_H to make GPAC use a separate config.h file
instead of the default configuration.h file
- Making an essentially empty config.h file to make attempts to include
it not fail
This commit also removes configuration.h from the repo to make sure we
don't accidentally include it, and removes the _GF_CONFIG_H_ hack from
the previously mentioned commit because we don't need it anymore (it's
sole purpose was avoiding using configuration.h).
* Link pthread and dl on Mac and Linux
Add -lpthread and -ldl to link pthread and dl respectively on Mac and
Linux. Needed because the update to GPAC 1.0.1 introduced os_thread.c
(which uses pthread) and os_module.c (which uses dlsym and related
functions).
* Remove unused Remotery.h header file
5c0c9cf71e removed the only use of
Remotery.h in the GPAC files that we pulled in, so there's no need to
keep it around.
* Add GPAC update to changelog
* Fix cmake build error
Building with CMake currently fails because it can't find functions from
dl (dlopen, dlsym, etc.)
* Fix bazel build error
Bazel currently doesn't find the header files in gpac/modules/ when
building gpac, most likely because it isn't searching all directories in
gpac/ recursively for header files
* Define GPAC_HAVE_CONFIG_H in lib_ccx BUILD file
lib_ccx indirectly includes gpac/tools.h, which tries to include
gpac/configuration.h, which was removed in
b46c4e8a2d. This just copies the solution
from that commit to the bazel BUILD file (defining GPAC_HAVE_CONFIG_H so
GPAC uses gpac/config.h instead).
* Link to dl and pthread in bazel GPAC BUILD file
The updated GPAC version requires functions from dl and pthread, which
weren't linked to previously when building with bazel.
