how to use x264 encoder with directshow
i can't figure out how to use x264 with directshow. i installed many thinks that pretend to have x264 encoder in with no use i downloaded the videoLAN x264 binary and when i run it, it shows so fast a console windows, and nothing happen after that
these is the encoders that i have
i am working on windows 8.1 x64
please help with this issue it's just going to make me crazy hhh, i wanna use x264 because the other encoders that i have installed, either didn't work or encode with so big size.
Answer
x264 itself does not have DirectShow interface, so you need a wrapper (or, you need to implement it yourself). x264vfw is wrapping x264 and exposes the encoder as VFW codec, and DirectShow uses VFW codecs through AVI Compressor Filter. Similar options are: direct264 and x264 wrapper by Monogram. Either way, an installed codec will show up on DirectShow filter list and will be available programmatically (the easiest way to ensure is SDK GraphEdit tool, or GraphStudioNext, or similar).
Once you have the codec installed, you can find it in the filter list. It is typical that the filter is registered into Video Compressors category (x264vfw is here for the example):
The filter extends DirectShow infrastructure and can be used... as documented, as other compressors. Video encoder are not used separately on their own, to build a valid DirectShow graph one normally has source/renderer filters in the topology, and a video encoder is a thing in between.
Below is example of DirectShow filter graph which leverages x264vfw video encoder, and transcodes Windows Media .WMV file into H.264 .MP4 file:
