The other is in the libavcodec source directory and The reason that config.h has been prebuilt is that this is one of the places you select whichĬodec(s) to enable/disable for ffmpeg.

It's not that difficult to figure out how to do. For more instructions on how to build libavcodec see:īear in mind that you should NOT run the configure script that comes with ffmpeg - it doesn'tĮxist in the hax264 directories - because config.h has been prebuilt for a Windows system. It is useful for integrated debugging with Visual Studio, however, which is why it's still There is a solution file included (and itĪctually builds the blasted thing) but it'll be way too slow, especially in debug mode. The ffmpeg portions (libavcodec) MUST be built using Msys and gcc.
If you have expertise in this area by all means get in touch and let's work in a newer solution! I can't seem to get the solution ported to anything newer, but that's probably just due to my unfamiliarity with Microsoft compiler environments. The compiler used for the filter is Microsoft Visual Studio 2003 dot Net. Have a slew of very peculiar unresolved externals. Your baseclasses library is built that way too (or change them both to dynamic) or you'll Mind that the actual ".ax" (DLL) file is built with static linkage to the runtime libs - be sure Someįolks include the baseclasses as part of the project to keep the build options in order,īut I don't feel comfortable mixing M$ and the GPL that closely. Pathing on my primary development machine can get a bit arcane, to say the least. You'll need to adjust your pathing to the DirectShow baseclasses library for sure. I found the original much easier to understand than the newer, "tryouts" version. Note that this is an early version of ffdshow. The base filter was created by DSWizard, and some portions were deduced by It ain't perfect, as they say, but it works! And I'm always open to hearing from those who have a better idea/implementation.

It was very difficult to find example code for a working filter that uses ffmpeg, so I hope that this may assist otherĭevelopers who face the same issues I faced when this had to be written.
However, this does expose the guts of a working DS filter - it could be easily modified to handle other underlying codecs. This is by design for patent liability reasons. Only the H264 codec from ffmpeg is exposed, and only the decoder is enabled. This filter wraps the libavcodec portion of the FFMpeg project.

It only registers for the "H264" FourCC, and the drivers are installed with "normal" priority, so it should coexist with other codecs peacefully. HAX264 is a DirectShow Video Transform Filter for decoding H264(AVC) video. Hax264 - Open Source DirectShow Decoding for H264(AVC) Video
