Reading that the ffmpeg internal ffvpx decoders/encoders are superior to those shipped by libvpx I recompiled ffmpeg with the --disable-libvpx option, but now I don't have vpx support at all. So did I misunderstand what --disable-libvpx does? I says that ffmpeg will link to the external library to get those encoders/decoders, exactly what I don't want. I also haven't found an option to explicitly enable ffvpx.

There is no "ffvpx" as such, what is there are the internal vp8 and vp9 decoders (just decoders, no encoders). They are available unless you explicitly disable them with --disable-decoder=vp8,vp9

I meant the internal decoders ffvp8 and ffvp9 with ffvpx. Good to know that there are no encoders, but I can't think of anything where I would need an encoder. I rebuild ffmpeg with --disable-libvpx and --enable-decoder='vp8,vp9' but still I don't have vpx support.

Again, there is no vpx in ffmpeg, there's vp8 and vp9. What exactly do you mean by "don't have vpx support", that you can't decode vp8 and vp9 video? Building ffmpeg, when ./configure finishes it lists everything that will be built, are vp8 and vp9 among the decoders in that list?
Offline
The x in vpx is just a placeholder for 8 or 9, sorry if this wasn't clear. Exactly, decoding of webm files (both with vp8 and vp9 codec) is not supported. vp8 and vp9 are in ffmpeg's configure output as enabled decoders. Linking against libvpx allows me to decode, but afaik other (from a different developer) decoders will be used.

Ok, that makes no sense. Post the full ./configure line you use and the output. Also, can you provide a sample file that doesn't play?

That configure output is weird. Like *really* weird, lots of stuff missing all over the place. So I tried your ./configure command locally. And my output was also weird! Basically, *do not set* --disable-random, it screws everything up. The reason you couldn't play webm files wasn't actually the lack of vp8/9, but the lack of a matroska demuxer (webm is a subset of matroska, so without a matroska demuxer you can't play webm files).
BTW, you don't need the --enable-hwaccel and --enable-decoder parts, you have everything enabled anyway.

It's funny how a --disable-random compile option can randomize so much... I removed that option und built again, now everything is working again.
