--disable-hwaccels does not disable hardware codecs: it disables hwaccels only, decoders and encoders will still be present. If you want to disable decoder and encoder wrappers as well then you will need to either use --disable-decoders --disable-encoders or disable them individually. (And that still doesn't disable filtering or hwcontext generic support using these libraries, which can be used separately.) > --disable-autodetect disables others besides the HW libs.

Under what circumstances does a user want to disable autodetect for some subset of libraries while allowing it for others? There can still be surprise dependencies, which is presumably the thing they want to avoid. > P.S. Isn't AMF for providing support for AMD GPU decoder/encoders? Just encoders, but yes. - Mark _______________________________________________ ffmpeg-devel mailing list firstname.lastname@example.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
