Intruducing a HEVC H.265 encoder

[hi3516a]

errors

[jagabo]

Does it work with HDCP protected streams?

[pandy]

利落的设计风格，恭喜你，

我希望谷歌的翻译是正确的

hi3516a seem to not supporting HDMI input (only output is visible on datasheet i can find) - jagabo question is then even more important.

[hi3516a]

Hi Jagabo, High-bandwidth Digital Content Protection (HDCP) 1.4 is support with internal HDCP keys
HDCP repeater support: up to 127 KSVs supported

Yes, there's no HDMI PHY inside the SOC, we use a ADI's HDMI receiver. The YUV paralell output port is coonected to Hi3516A's VI port.

[hi3516a]

3g-SDI interface is under developing

[jagabo]

Hi Jagabo, High-bandwidth Digital Content Protection (HDCP) 1.4 is support with internal HDCP keys
HDCP repeater support: up to 127 KSVs supported

Could you clarify what you mean by this? Can the device record HDCP protected sources?

[hi3516a]

Sure, it can record HDCP protected sources.

[jagabo]

So, are you selling them? If so, how much? Can it encode as h.264 too?

[lordsmurf]

"we" use?
Sounds like an ad to me.

[hi3516a]

Hi Jagabo,
Yes, it could encode the video into both H265 and H264. both stream at the same time

非常好!

多少钱?

[ezcapper]

how is it powered. Do you just put in a PCI Express port and it works? Is it powered by the usb port. I'm not technically savvy, sorry for the stupid questions.

[hi3516a]

It is not a PCIE card, it would work standalone, so it is powered by a DC adapter with DC7V~14V .
It do has a USB OTG port, a 4G/LTE module or a WIFI module could be connected to the USB port. now we are just show a live demo of realtime H.265 encoding and 4G wireless transmission, you could use VLC to watch our hevc streaming. The video server address is:
rtsp://123.57.230.189:554/test.sdp

[ezcapper]

VLC is saying that the input cannot be opened. Is it compatible with 3d sources, will it produce 3d output? how much is the card?

And to make it work, you would only have to buy a DC Adapter like this one?:
http://www.amazon.com/Power-Adapter-2-1mm-Regulated-Supply/dp/B006QYXFRO/ref=sr_1_1?s=...4Z2KECPRJVZTWB

Is there a place on the board to plug in the adapter?

Thanks for your help!

[hi3516a]

Only VLC 2.2.1 or later could support H265 stream. If yes, please try again now.

[hi3516a]

setup VLC-media-player,use network streaming

[hi3516a]

you could also get some basic information

[ezcapper]

Thanks for the help. It might be the computer I was on had limited permissions. How much are you selling the card for?

Is there an adjustable bitrate?


The stream appears to be down today, but I recorded a ~21sec test with ffmpeg yesterday attached below if anyone is interested

ffmpeg -i rtsp://123.57.230.189:554/test.sdp -c:v copy -c:a copy out.mp4

There appear to be some duplicate frames /frame drop issue (picture pauses, but the scrolling overlay continues) . In a few places, the overlay jumps too, but the picture moves (so a disconnect between the two), and in others the drops are synchronized (both overlay and picture have drops or duplicates). But the main picture drops are too frequent to be merely a 24p/25p conversion. These things might indicate either network / bandwidth issue but it could be a card issue, or a source issue, or recording issue - hard to say without more info

at that bitrate, that's good enough for my needs, as long as it doesn't drop frames when recording to media. This technology is very fascinating!

Is there an adjustable bitrate?

apparently I missed this in the first post

Supporting the CBR/VBR bit rate control mode, ranging
from 16 kbit/s to 40 Mbit/s

I searched for "bitrate", but not "bit rate" in the browser...DUH

Just wondering, what can this card do that the ZIDOO X9 Quad Core Media Player can't?

Does that box capture and encode HDCP protected video?

[Selur]

from what I read so far, that the zidoo can too (up to 4k resolution using HEVC and AAC with mp4 and mkv as container).

I don't believe that the zidoo x9 can encode using HEVC. It only has a HEVC decoder. Thus the $650 price difference between the two. If you want the recording features of the zidoo x9 only, the tronsmart pavo m9 is very similar, but less expensive than the zidoo. But both those boxes are not at the level of this box recording wise.

But you bring up a very good point. In a couple years, Chinese Android boxes will make capture cards obsolete. The tronsmart pavo m9 can capture apple tv out of the box. An elgato, hauppage, avermedia, etc. will never be able to do that. You get a whole capture computer for the price of a video capture card.

This is a guy recording with the zidoo:

It is now upgrade to a single board. H265 encoding+Ethernet+HDMI.
