Re: Upgrading to a newer kernel version in Starkl

The 4.16 kernel I've pointed you to, will boot, what interfaces do you need support for? The encoder for example works in the latest kernel, but the HDMIrx doesn't (neither does the decoders), but we could probably give you code to do decoding in the newer kernel, what we don't currently have (but i...

Re: Upgrading to a newer kernel version in Starkl

The specific kernel repo is at https://bitbucket.org/4kopen/linux/src/4kopen-bringup/

It's currently 4.16 but we have a v5.0 as well.

Re: Upgrading to a newer kernel version in Starkl

Hi, We are working on the newer kernel, this however won't be in STARKL it will likely be in Raspbian, and we will have buildroot and poky solutions, this is currently work in progress. Most can be found on the bitbucket repositories, and https://mathembedded.atlassian.net/wiki/spaces/4K/pages/11748...

Re: OpenMAX IL for h.264 stream

I'm able to create the decoder component & change states to loaded. I ran into a problem with my test program transitioning states to idle because the ST OMX implementation is complaining that it doesn't support NON tunnel'ed mode. I'm only using the decoder right now, so there is no need for tunne...

Re: OpenMAX IL for h.264 stream

Hi Doug, Ok so there are open max plugins, though I'm not sure this is the right way to go. Gstreamer is the supported interface we are using, for playback, have you seen the wiki for playing back. As for the webcam, but it's likely the webcam doesn't have the drivers, we are currently just enabling...

Re: Decoding HDMI with HDCP copy protection from cable boxes

Hi Doug,

The STiH418 does support HDCP on both the RX and TX, the TX can be enabled if you have HDCP keys, and an HDCP license.

HDCP RX however requires a different sales type with RX enabled, and is not enabled on the 4Kopen board (for obvious reasons).

Cheers

Re: Encoding from HDMI Rx

Hi Vasvu,

The example is at the top of the post:

Code: Select all

hdmirx-capture --dec-id=0 --dvp-start --vid-capture-profile=2 --debug --encode /tmp/video.ts
Though we also recommend:

Code: Select all

mkfifo /tmp/video.ts
Then you can read the other side of the pipe using cat or gstreamer to stream the TS file.

Re: IEEE-1588

> Q1: What is the clock that is used by 1588 hardware counter. From the code I would say 215MHz, though it's converted based into one of two values: /* Convert the ptp_clock to nano second * formula = (1/ptp_clock) * 1000000000 * where, ptp_clock = 50MHz. */ data = (1000000000ULL / 50000000); /* 0.4...
