No, because I had hardware H.264 encoder support. :-) (The decoding in FFmpeg on the other side was still software. But it was seemingly much cheaper to do a H.264 software decode.)

At some point, I had a similar issue (though not related to licensing), and it turned out it was faster to do a high-bitrate H.264-encode of the stream before sending it over the FFmpeg socket than sending the raw RGBA data, even over local

I guess not a lot of games really use OpenGL at all anymore? But I haven't gone around and tried making a survey. :-)

OpenGL also supports SPIR-V, a similar intermediate format, since 2017 (it came into core in OpenGL 4.6).

For NES Tetris, playing on PAL is basically considered easy mode. Some of the top players have been doing it to train for difficult feats.

Yes, I think “only rarely useful” covers it :-) I know there are some codecs that support it, e.g. VP9?

The big change is basically that we now typically specify exactly which integer approximation to the (real-valued, “ideal”) DCT to use; this means the decoder and encoder is much likely to fall out of sync. As a bonus, this means we can use

by Sesse__ 2y ago
The DCT, just like the DFT, is a discrete version of the (analog) Fourier transform. (FFT is just a clever, fast implementation of the DFT, just like when people say “DCT” they usually mean a similarly fast implementation of the DCT. Call i

My basic problem is that I'm really struggling to hear the difference between many of your samples :-) And I've already got a bit of experience with microtonality (DSP background, playing and have tuned multiple instruments, reaso

If you have two addresses in the same /64, you know almost certainly they are on the same LAN. If you have two addresses in neighboring /64s (same initial 63 bits), or in general within the same /48 (same initial 48 bits), yo

By being part of a larger, routable prefix. gnfargbl didn't say the _address_ was unroutable, but that effectively, routing policies mean that /48 is a common minimum unit for administrative purposes (similar to how /24 has a

by Sesse__ 2y ago
But the /64 would not be publicly routable (i.e., be visible in the global BGP table). I guess in practice, it's more like IPv4 /24 = IPv6 /48, though. The closest analog to an IPv4 /32 would probably be an IPv6 &#x

I agree with that statement, but it has nothing to do with snprintf() versus e.g. strcpy_s(), where you have exactly the same requirement to pass the right size. (Separately, there's a discussion about how many bytes you are allowed to

by Sesse__ 2y ago
The sanest solution is, surprisingly, snprintf(dst, sizeof(dst), "%s", src).

I sometimes write intrinsic comparisons (e.g., something like "x < 'a'" instead of "_mm_cmplt_epi8(x, _mm_set1_epi8('a'))") just to make sure the compiler understands what's going on and can d

One thing that's not all that obvious from this large chunk of assembly is that Clang manages to rewrite (x >= 'a' && x <= 'z') into (x - 'a') < <some constant> which s

In NetWare 4.x (and even more so in 5.x), you could give NLMs their own address space. But by then, it was probably lost anyway.

By default, it seems git-send-email adds the in-body From: with the committer. (I don't know if git am picks this up, but I suppose it does.) If I add --from _after_ $oldsha..$newsha, it seems that's the git-format-patch --from, w

I deliver and read mail locally. I don't think that matters a whole lot in this case, though? As long as you can send email from your server to yourself somehow, I guess you're fine.

It is so that the push doesn't actually become a push. :-) If the pre-receive hook exits with success, the push goes through and random people can write whatever they want to my repository. If it fails, the repository is left exactly a

They also, effectively, fit information in the indexes of the parameters. I.e., _which_ of the parameters are nonzero carries real information. In a sense, they have done their fitting using nine parameters, of which five are zero.

And I do vividly recall someone saying that the later CS betas had lag-compensating things that were unfair, and invited others to play beta 1, “where you actually hit what you aim at”!
