* Add support for building shared libraries with MSVCMartin Storsjö2012-10-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This requires the makedef perl script by Derek, from the c89-to-c99 repo. That scripts produces a .def file, listing the symbols to be exported, based on the gcc version scripts and the built object files. To properly load non-function symbols from DLL files, the data symbol declarations need to have the attribute __declspec(dllimport) when building the calling code. (On mingw, the linker can fix this up automatically, which is why it has not been an issue so far. If this attribute is omitted, linking actually succeeds, but reads from the table will not produce the desired results at runtime.) MSVC seems to manage to link DLLs (and run properly) even if this attribute is present while building the library itself (which normally isn't recommended) - other object files in the same library manage to link to the symbol (with a small warning at link time, like "warning LNK4049: locally defined symbol _avpriv_mpa_bitrate_tab imported" - it doesn't seem to be possible to squelch this warning), and the definition of the tables themselves produce a warning that can be squelched ("warning C4273: 'avpriv_mpa_bitrate_tab' : inconsistent dll linkage, see previous definition of 'avpriv_mpa_bitrate_tab'). In this setup, mingw isn't able to link object files that refer to data symbols with __declspec(dllimport) without those symbols actually being linked via a DLL (linking avcodec.dll ends up with errors like "undefined reference to `__imp__avpriv_mpa_freq_tab'"). The dllimport declspec isn't needed at all in mingw, so we simply choose not to declare it for other compilers than MSVC that requires it. (If ICL support later requires it, the condition can be extended later to include both of them.) This also implies that code that is built to link to a certain library as a DLL can't link to the same library as a static library. Therefore, we only allow building either static or shared but not both at the same time. (That is, static libraries as such can be, and actually are, built - this is used for linking the test tools to internal symbols in the libraries - but e.g. libavformat built to link to libavcodec as a DLL cannot link statically to libavcodec.) Also, linking to DLLs is slightly different from linking to shared libraries on other platforms. DLLs use a thing called import libraries, which is basically a stub library allowing the linker to know which symbols exist in the DLL and what name the DLL will have at runtime. In mingw/gcc, the import library is usually named libfoo.dll.a, which goes next to a static library named libfoo.a. This allows gcc to pick the dynamic one, if available, from the normal -lfoo switches, just as it does for libfoo.a vs libfoo.so on Unix. On MSVC however, you need to literally specify the name of the import library instead of the static library. Signed-off-by: Martin Storsjö <martin@martin.st>
* avcodec: Rename avpriv_frame_rate_tab to ff_mpeg12_frame_rate_tabMartin Storsjö2012-10-18
| | | | | | | This table doesn't need to be shared with libavformat any longer. Add mpeg12 to the name to make it less ambiguous, while renaming it. Signed-off-by: Martin Storsjö <martin@martin.st>
* gxf: Add a local copy of the relevant parts of the frame rate tableMartin Storsjö2012-10-18
| | | | | | | | | | | | | This avoids having to share this table across the library boundaries. This shared table used to be problematic, if always declaring all exported data symbols with the dllimport attribute (even while building that same library), since it needs to be a link-time constant when it is used in AVCodec declarations (in mpeg12enc.c).

* configure: Split out msvc as a separate target OSMartin Storsjö2012-10-18
| | | | | | | | | | The name mingw32 as target OS is both misleading, and very little of the target OS specific settings actually match. Since the target OS default is set based on uname, the default (which on MSYS is set to mingw) is overridden by --toolchain=msvc. Signed-off-by: Martin Storsjö <martin@martin.st>
* aviobuf: Remove a senseless ifdef in avio_seekMartin Storsjö2012-10-18
| | | | | | | | | This seemed to assume that one never used writing avio unless muxers or networking was enabled. This ifdef is a remnant since 8fa641f8. Signed-off-by: Martin Storsjö <martin@martin.st>

* libmp3lame: resize the output buffer if neededJustin Ruggles2012-10-17
| | | | | | | | | The LAME API documentation for the required buffer size refers to the size for a single encode call. However, we store multiple frames in the same output buffer but only read 1 frame at a time out of it. As a result, the buffer size given in lame_encode_buffer() is actually smaller than what it should be. Since we do not know how many frames it will end up buffering, it is best to just reallocate if needed.

| | | | | | | | | For a sample size of 32 bits, the shift would overflow producing undefined results.

* swscale: try to use mmap only if availableMans Rullgard2012-10-15
| | | | | | | | | | | | Some systems, e.g. Minix, have sys/mman.h defining MAP_ANONYMOUS without providing (working) mmap and friends. The mmx filter generation code checks only for MAP_ANONYMOUS, not for availability of mmap itself which leads to build errors on aforementioned systems. This changes the conditional compilation to use mmap only if all the required functions are available. Signed-off-by: Mans Rullgard <mans@mansr.com>
