* configure: Don't do enable_deep_weak on disabled variablesMartin Storsjö2013-05-02
| | | | | | | | | | | | | This avoids cases where configure tries to weakly enable an item which actually is disabled, ending up still enabling dependencies of the item which itself is only enabled weakly. More concretely, the h264 decoder suggests error resilience, which is then enabled weakly (unless manually disabled). Previously, dsputil, which is a dependency of error resilience, was enabled even if error resilience wasn't enabled in the end. Signed-off-by: Martin Storsjö <martin@martin.st>
* configure: Use a different variable name in push/popvarMartin Storsjö2013-05-02
| | | | | | | | | The variable name 'var' is commonly used to iterate through arguments in other functions. When the pushvar function internally uses the variable 'var', it makes pushing/popping the variable 'var' not work as intended. Signed-off-by: Martin Storsjö <martin@martin.st>

* mpegvideo: Use hpeldsp instead of dsputil for half-pel functionsRonald S. Bultje2013-04-19
| | | | | | This also converts vc1, since that is mpegvideo-based. Signed-off-by: Martin Storsjö <martin@martin.st>

* Integrate lcov/gcov into LibavReinhard Tartler2013-04-05
| | | | | | | The gcov/lcov are a common toolchain for visualizing code coverage with the GNU/Toolchain. The documentation and implementation of this integration was heavily inspired from the blog entry by Mike Melanson: http://multimedia.cx/eggs/using-lcov-with-ffmpeg/
* clang: use -fsantize=address and -fsanitize=threadLuca Barbato2013-04-03
| | | | The previous syntax is deprecated.
* configure: Check for the atomic.h functions used in the suncc atomics headerMartin Storsjö2013-04-03
| | | | | | | The "suncc" atomics implementation uses a suncc specific memory barrier, but also relies on a few atomic functions from atomic.h, that are not suncc specific but specific to solaris. This made the current implementation fail on suncc on linux.
* configure: prettify atomics handling.Anton Khirnov2013-04-03
| | | | | Add simpler names and a shorthand for native atomics (as opposed to pthreads fallback).
* configure: Add error_resilience as dependency to the eatqi decoderMartin Storsjö2013-03-27
| | | | | | | This makes standalone compilation of the eatqi decoder succeed. The dependency comes from the shared mpeg12dec.o file. Signed-off-by: Martin Storsjö <martin@martin.st>

* configure: Remove the mpegvideo dependency from svq1Martin Storsjö2013-03-26
| | | | | | The svq1 decoder can be built standalone without mpegvideo. Signed-off-by: Martin Storsjö <martin@martin.st>
* h264: Make it possible to compile without error_resilienceRonald S. Bultje2013-03-26
| | | | | | | | | | Error resilience is enabled by the h264 decoder, unless explicitly disabled. --disable-everything --enable-decoder=h264 will produce a h264 decoder with error resilience enabled, while --disable-everything --enable-decoder=h264 --disable-error-resilience will produce a h264 decoder with error resilience disabled. Signed-off-by: Martin Storsjö <martin@martin.st>
* lavc: Move start code finding to utils.cMartin Storsjö2013-03-26
| | | | | | | | | | This allows dropping the mpegvideo dependency from a number of components. This also fixes standalone building of the h264 parser, which was broken in 64e438697. Signed-off-by: Martin Storsjö <martin@martin.st>

* atomic: Check for __sync_val_compare_and_swap instead of __sync_synchronizeMartin Storsjö2013-03-08
| | | | | | | | | | | | Not all gcc configurations have an implementation of all the atomic operations, and some gcc configurations have some atomic builtins implemented but not all. Thus check for the most essential function, whose presence should indicate that all others are present as well, since it can be used to implement all the other ones. Signed-off-by: Martin Storsjö <martin@martin.st>
* lavu: add support for atomic operations.Ronald S. Bultje2013-03-08
| | | | | | | | | | These could be used for reference counting, or for keeping track of decoding progress in references in multithreaded decoders. Support is provided by gcc/msvc/suncc intrinsics, with a fallback using pthread mutexes. Signed-off-by: Anton Khirnov <anton@khirnov.net>

* h264: Integrate draw_horiz_band into ff_h264_draw_horiz_bandRonald S. Bultje2013-03-07
| | | | | | | | | | This makes the decoder independent of mpegvideo. This copy of the draw_horiz_band code is simplified compared to the "generic" mpegvideo one which still has a number of special cases for different codecs. Signed-off-by: Martin Storsjö <martin@martin.st>
