| | | | | | | | | | | | | | | | The loops were reading ahead one line, which could end up outside the buffer for reference blocks at the edge of the picture. Removing this readahead has no measurable performance impact. Signed-off-by: Mans Rullgard <mans@mansr.com>

| * indeo3: do not try to output more lines than we can fitKostya Shishkov2012-10-19
| | | | | | | | | | | | | | | | Internally chroma planes have multiple of four height while allocated image planes might be smaller if CODEC_FLAG_EMU_EDGE is set. Thus we should not output more lines of chroma than frame can accept. Also the decoder can be safely switched to direct rendering now.

| | | | | | | | | | | | | | | | | | | | | | aac_tablegen.h includes aac.h for the POW_SF2_ZERO definition, but this also pulls in a raft of other headers, some of which are not safe to use in code built with the host compiler. Moving POW_SF2_ZERO to aac_tablegen_decl.h, where the declaration of the array it relates to already resides, fixes the problems. Signed-off-by: Mans Rullgard <mans@mansr.com>

| * 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>

| * 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.
