Two questions:
1) Why does the Linux installation page recommend installing libgl1-mesa-dev. I seem to compile and run fine without it. Is there some feature that this enables?
2) Why is the --no-yasm flag recommended to compile ffmpeg? Is it just so you don't have to install yasm to build it? Doesn't this potentially make the resulting library slower, or does the functionality used by makemkv not use any assembly code?

Yes, no asm code used by audio codecs. Just not to install yasm.kevmitch wrote:or does the functionality used by makemkv not use any assembly code?
Re: libgl1-mesa-dev and --no-yasm
That would be incorrect. Some of it is inline, but you'll also find some in libavcodec/x86/ac3dsp.asm, libavcodec/x86/imdct36.asm, and so on which require yasm (or nasm) and are used by audio decoders.mike admin wrote:Yes, no asm code used by audio codecs.

No idea what the impact is on overall performance though.
