Posted by Charbax – October 3, 2017

Mark Gregotski, DIrector of the Linaro Digital Home Group, provides an update on the latest work in open source for the Digital Home Group that LHG is working on including the adoption of OP-TEE (Open Portable Trusted Execution Environment) with DRM integrations including PlayReady DRM PK v3.3 on AOSP 8.0 on the HiKey960 development board and Widevine for Linux and for Android AOSP. NXP demonstrates some of their work, NXP has recently joined the Linaro Digital Home Group. The LHG group has worked to integrate V4L2 with gstreamer and ffmpeg to improve media playback on ARM offloading all the computation onto the video codec hardware of the SoC.

Autofocus test on Firmware 2.0 Panasonic GH5

Posted by Charbax – September 28, 2017

I am doing my first handheld autofocus test using the Panasonic GH5 and its new Firmware 2.0 update. I'm hoping that the auto-focus may be good enough for my style of handheld, always moving, constantly re-framing, focusing on faces and things people show off. What do you think about this Autofocus performance? This was filmed with Serge Broslavsky at Linaro Connect 2017, see his GH5 setup here. This video was filmed at 4K60p at 150mbit/s H264. Thus far the Panasonic GH5 firmware can't film 4K60 in HLG HDR mode and they don't yet offer an H265 option at 4K60 to save on bitrate at same quality for faster YouTube uploading.

Serge Broslavsky’s GH5 setup with Zoom H5, monopod, light, some DIY, some from Aliexpress

HDMI alt mode USB Type-C in a UHD Blu-ray player

Posted by Charbax – September 26, 2017

HDMI Licensing Administrator shows 4K60 Premium Certified HDMI alt mode over USB Type-C Connector on a modified UHD Blu-ray player, by just re-routing the HDMI signal instead of going to an HDMI connector can transfer the same HDMI signal through the USB Type-C connector. For now devices like smartphones, tablets and PCs who want to be able to output HDMI signal over USB Type-C need to have a small chip to transfer the HDMI signal but later some SoCs might be adding this functionality directly onto the SoC.
