I was referring to consumer DRM systems, not in-theater projection systems. Is there also a concern of Netflix-bitrate 4K video being used in theaters?

Color theory has been extremely well researched for quite a long time. If you are not familiar, I would suggest reading up on the CIE 1931 color space [1]. Some of the confusion in the article relates to terminology. >When we say “yellow

This is the opposite of my experience (assuming the same performance level). Though I consider FPGAs and GPUs mostly cut out for vastly different purposes. I unfortunately can't find a good reference to back this up because very few pe

FPGAs are certainly not known for their low power consumption. Especially for something like an OpenCL workload, you'd probably do much better with a vector processor architecture, like on GPUs.

by TD-Linux 12y ago
>(I actually don't know so feel free to correct me). Okay, I will :) Many FPGAs load their program from a SPI chip on board, which can't be reprogrammed. However, it's increasingly common for another microcontroller or SoC

Don't forget the rather oppressive DRM required by Hollywood for 4K video content. This is why 4K is currently only available for Netflix original content.

Emscripten generates asm.js code by default. Also Emscripten should be C standard compliant. So any behavior that isn't correct is likely an Emscripten bug.

The license costs for HE-AAC alone are probably more than the FM radio chip, unfortunately.

ORTC is just an API. The WebRTC protocol itself is defined in RTCWEB at the IETF and based on the existing RTP and RTCP transports, and SCTP transport layer. I don't think you'll be able to do better.

WebRTC already has p2p support for group chat. appear.in is one example of an implementation. The main limitation is that upload bandwidth scales linearly with the number of people in the group chat. But that's often OK for up to 10 or

I don't really think it's appropriate to use LWN subscriber links on HN, by the way.

6" is the diagonal measurement. So that's 1800 pixels diagonally. 1080p is 1920x1080, so about 2200 pixels diagonally. I absolutely love the look of the crisp text on the Nexus 6, but I don't think that it would be very visib

Most consumer sources are also-limited to 8-bit precision. 10-bit encodes from these are made using a fancy temporal debanding filter, which only works in certain cases. Keep in mind that there is a range expansion when converting to monito

The Qualcomm Snapdragon 805 in the Nexus 6 fully supports VP9 hardware acceleration. Though I'm not sure about the benefits of 4K video on a 6 inch screen.
945.
by TD-Linux 12y ago
Qualcomm and Samsung's SoCs now support VP9. In addition, nVidia's K1 and newer SoCs also support it.
946.
by TD-Linux 12y ago
I think many thought this a year ago, but it's not the case any more. All of the major SoC vendors are shipping VP9 in their newest system-on-chips. In addition, a new licensing pool for HEVC just formed, and has yet to announce their

Yes. Use the -F flag and any formats that are WebM / DASH use this format.

I also have XfinityWifi. The box that provides it is extremely buggy. I recommend setting it to "Bridge mode" (which turns it into a dumb modem) and then using OpenWRT in a normal, router configuration. You get a really good speed

In the case of NETVC, all contributors are required to submit IPR declarations. This doesn't prevent other uninvolved parties from popping up with patents later, but is still far better than the "patent-blind" approach that M

As another point of reference, you can compare the licensors in the MPEG-LA H.264 patent pool: http://www.mpegla.com/main/programs/AVC/Pages/Licensors.aspx with those in the MPEG-LA HEVC patent pool: ht

If you haven't looked at in a while, you should try VP9 again. It is much faster, especially if you try the new 1.4.0 release candidate. Also keep in mind that MPEG 4 includes two separate video codecs, ASP and AVC, with wildly differe

Indeed, uBlock was the problem. I'll file a bug.

How does this differ from OpenSCAD? The example looks nearly identical.

Unfortunately, BPG is heavily patent encumbered so no one can risk shipping it right now.

They are very similar. Both include an explicit patent grant. However, GPLv3 requires that redistributions keep the original HDL intact, which I prefer. Also, the fact that one of the primary authors considers it a good choice for hardware

This was an incredibly well written article. I didn't realize who had written it until it referenced the GPLv3. The arguments are convincing enough that I'm going to use GPLv3 rather than the Apache 2.0 license for my future open
