* avcodec: add metadata to identify wrappers and hardware decoderswm42017-12-14
| | | | | | | | | | | | | | | | | | | | | Explicitly identify decoder/encoder wrappers with a common name. This saves API users from guessing by the name suffix. For example, they don't have to guess that "h264_qsv" is the h264 QSV implementation, and instead they can just check the AVCodec .codec and .wrapper_name fields. Explicitly mark AVCodec entries that are hardware decoders or most likely hardware decoders with new AV_CODEC_CAPs. The purpose is allowing API users listing hardware decoders in a more generic way. The proposed AVCodecHWConfig does not provide this information fully, because it's concerned with decoder configuration, not information about the fact whether the hardware is used or not. AV_CODEC_CAP_HYBRID exists specifically for QSV, which can have software implementations in case the hardware is not capable. Based on a patch by Philip Langdale <philipl@overt.org>.

* lavc/qsvenc: set HRD buffer sizeLi, Zhong2017-12-12
| | | | | | | | | | Hypothetical Reference Decoding (HRD) model assumes that data flows into a buffer of the fixed size BufferSizeInKB with a constant bitrate. Smaller BufferSizeInKB means smaller frame size variations, but more difficult to maintain HRD. Signed-off-by: Zhong Li <zhong.li@intel.com> Signed-off-by: Maxym Dmytrychenko <maxim.d33@gmail.com>

* libavcodec: Don't use dllexport, only dllimport when building DLLsMartin Storsjö2017-11-19
| | | | | | | | | | | | | | | | | | | | The only purpose of dllexport (which is set while building the library that exports the symbols) is to have the linker automatically export such symbols into a DLL without using a def file - it doesn't affect the generated code. For both MSVC and mingw builds, this isn't essential since we override what symbols to export via an autogenerated def file instead. Update a comment in configure to refer to the right concept. With lld, this avoids warnings about duplicate export directives, when some symbols are requested to be exported both via dllexport attributes and via the autogenerated def file. This also reduces the number of lines of code marginally. Signed-off-by: Martin Storsjö <martin@martin.st>
* makedef: Pass EXTERN_PREFIX from configure to makedefMartin Storsjö2017-11-16
| | | | | | | | | | This avoids having to use either "dumpbin -headers" to find out the current architecture, or pass $ARCH from configure to deduce it. When configuring with --disable-asm, ARCH is equal to "c", which doesn't give any indication of what symbol prefix is to be used. Signed-off-by: Martin Storsjö <martin@martin.st>

* vaapi_h264: Do not use deprecated header typeMark Thompson2017-11-12
| | | | | SEI headers should be inserted as generic raw data (the old specific type has been deprecated in libva2).
* vaapi_h264: Add workaround for bad SEI in old Intel driversMark Thompson2017-11-12
| | | | | | | | | | | | | | With pre-2.0 Intel drivers in CBR mode, if an explicit SEI message with the old (now deprecated) type is not included, the driver generates and inserts some timing SEI which is almost certainly invlaid. Before 7a4fac5e91789b73e07bd4ad20493cfde028df76 we always inserted our own SEI so this would not be visible, but since then it has been possible to disable that. We would also like to avoid using the deprecated type, and using the new type, while working in old drivers, does not suppress the spurious message like the old type does. Therefore, suppress the bad SEI insertion by providing a zero-length buffer with the old type, which the driver can insert harmlessly.

* libspeexenc: Use speex_lib_get_mode instead of the speex_foo_mode data symbolsMartin Storsjö2017-11-04
| | | | | | | | | | | | | This avoids issues linking to a DLL version of libspeex, since the libspeex headers lack proper dllimport declarations for the data symbols. This isn't an issue when building with mingw with GNU binutils, since GNU ld can fix up that kind of data import automatically. libspeexdec.c already uses speex_lib_get_mode as well.

* configure: Stop using dlltool to create an import libraryMartin Storsjö2017-10-30
| | | | | | | | | | | | | | | There shouldn't be any functional difference between the import library created by dlltool and the one produced by the linker itself. Keep installing it with both names though, for compatibility with users that expect both to exist. The dlltool step was added in ec10a9ab4; prior to that, a MSVC compatible import library was generated using lib.exe. After that commit, there was no functional difference between the two import libraries (and since MSVC 2012, link.exe works just fine with the GNU binutils generated one).
