And what does Chromecast or Ugoos, what does not have Dune for FEL to work? For the same reason, don't you think Dune adds support through FW? i hope so if Another streaming devices apparently have FEL support now...
I have no idea, it's very surprising that not 1 but 2 streaming devices can do FEL...
But can they really do it properly? that's why I want @manix to capture the Total Recall scene with his Atomos Shogun.
As someone mentioned already, if you look at the
S922X spec sheet (AM6 Plus SoC is S922X-J) on page 12:
- Amlogic Video Engine (AVE) with dedicated hardware decoders and encoders
- Support multi-video decoder up to 4Kx2K@60fps+1x1080P@60fps
- Supports multiple “secured” video decoding sessions and simultaneous decoding and encoding
Similarly, the
S905D3 spec sheet (Chromecast with Google TV's SoC) on page 11:
- Amlogic Video Engine (AVE) with dedicated hardware decoders and encoders
- Support multi-video decoder up to 4x1080P@60fps
- Supports multiple “secured” video decoding sessions and simultaneous decoding and encoding
So, they are both hardware-capable of decoding 1x2160p@23.976fps + 1x1080p@23.976fps simultaneously, which is BL+FEL @23.976fps (majority of DV UHD releases). In theory, the AM6Plus could handle BL+FEL @60fps while the Chromecast with Google TV could not, although no 60FPS DV FEL UHD has been released to date to test this (Gemini Man is 2160p@60fps MEL).
The key thing enabling proper FEL decode on these SoCs seems to be the AVE-10 hardware decoder:
Amlogic Video Engine(AVE-10) off-loads the Cortex CPUs from all video CODEC processing. It includes dedicated hardware video decoder and encoder.
Perhaps this explains why the RTD1619DR (Dune Pro/Max Vision 4K and Zidoo Z9X/UHD3000/Z10 PRO/Z1000 PRO) is not capable of decoding FEL, despite having a very similar CPU/GPU (6xARM Cortex-A55 + ARM Mali-G51 MP3) to the S905D3 (4xARM Cortex-A55 + ARM Mali-G31 MP2) and S922X-J (4xARM Cortex-A73+2xARM Cortex-A53 + ARM Mali-G52 MP6).
