AOMedia AV2 open video codec release nears, delivers around 40% bandwidth reduction

The Alliance for Open Media (AOMedia) will release the AV2 open video codec specification by the end of the year, as an update of the now widely-used AV1 video codec with up to 40% bandwidth reduction at the same level of quality. In the meantime, Debargha Mukherjee, Google Principal Engineer, has shared a progress report about AV2, first offering a historical perspective with the list of digital video codecs from 1990 to 2030 (expected), then stating AV2 goals, and going through requirements, coding tools, and what’s been achieved so far. You can check the eleven-minute presentation (04:27 – 15:30) embedded at the end of this post, or continue reading for the highlights of the talk. AV2 will be released very soon, while the H.267 proprietary video codec might only be released around 2030. We haven’t seen a lot of support/traction for H.266, so we’ll have to see if H.267 ever […]

Ugoos AM9 Android 14 TV box features Amlogic S905X5 Armv9 SoC, supports H.266 and AV1 codecs

Ugoos AM9 is an Android 14 TV box powered by an Amlogic S905X5 quad-core (Armv9) Cortex-A510 SoC, which supports features such as H.266 and AV1 hardware video decoding and AI Super Resolution (AI-SR) through the built-in 4 TOPS NPU. We first noted the Amlogic S905X5 SoC in an upcoming SEI Robotics TV box about two years ago. Details were sparse at the time, and in the meantime, Amlogic introduced the similarly named S905X5M, which is still a “regular” Armv8 SoC with four Cortex-A55 cores, and found in products such as ODROID-C5 SBC and Ugoos X5M Pro. However, I had not heard anything about the more powerful S905X5 SoC until I came across the Ugoos AM9 TV box this morning. Ugoos AM9 specifications: SoC – Amlogic S905X5 CPU – Quad-core Cortex-A510 Armv9 processor delivering 40K+ DMIPS GPU – Arm Mali-G310 V5 GPU clocked at 1 GHz for 4K HDR user interfaces […]

Xiaomi TV Stick 4K (2nd Gen) – A quad-core Cortex-A55 TV Stick with Google TV

We’ve just written about the Ugoos X5M Pro as one of the first Amlogic S905X5M TV boxes, but the market is expanding, and Xiaomi TV Stick 4K (2nd Gen) Google TV dongle is now available as a smaller version of the company’s Xiaomi TV Box S (3rd Gen) based on the same or similar processor. The TV stick features 2GB RAM, 8GB eMMC flash, a 4K-capable HDMI male port, and WiFi 6 and Bluetooth 5.2 connectivity, and not much else, as one would expect from an HDMI TV stick. It ships with a Bluetooth remote that supports Google Assistant voice commands. The company did not list the exact part number of the processor, and while it matches the Amlogic S905X5M specifications, it should be another model without Ethernet support, like Amlogic did in the past with the S905Y4, so maybe an S905Y5M? Xiaomi TV Stick 4K (2nd Gen) specifications: SoC – […]

MECOOL KM9PRO MAX 4K Streaming Box runs Google TV 12.0 on Realtek RTD1325 SoC

MECOOL KM9PRO MAX 4K is a Google TV 12.0 streaming box based on the Realtek RTD1325 quad-core Cortex-A55 SoC which we initially found in the Formuler Z Mini 4K Android 12 dongle. Since it’s a more traditional TV box as opposed to an HDMI dongle, it adds features like 10/100Mbps Ethernet, optical S/PDIF output, an AV composite and audio jack, two USB 2.0 ports, while keeping the 4K-capable HDMI 2.1 port and WiFi 5 and Bluetooth 5.0 connectivity. The KM9PRO Max 4K also comes with a larger 32GB eMMC flash.

Amlogic S905X5M vs S905X4 – Features and benchmarks comparison

Amlogic S905X5M is an update to the Amlogic S905X4 quad-core Cortex-A55 SoC with a higher 2.5 GHz CPU clock and a new generation Arm G310 CPU that delivers up to close to three times the performance of the Mali-G31 MP2 GPU for more advanced and smoother HDR user interfaces. The S905X5M and S905X4 share the same video decoding capabilities, notably AV1 and H265 up to 4Kp75, but the new S905X5M drops support for H.265 1080p60 video encoding, only keeping H.264 1080p30. One of the new features is the inclusion of an NPU designed specifically for Super Resolution enabling video upscaling with better image quality. You’ll find the differences between the Amlogic S905X5M and S905X5 processors in the comparison table below. The Amlogic S905X5M adds some HDMI 2.1 features that deserve an explanation: QMS (Quick Media Switching) – A source device can instantly switch its content’s resolution or frame rate without […]
