k0los Posted September 6, 2018 Posted September 6, 2018 (edited) Hello, I am looking for a cheap SoC (less than 15$ per SoC) that has the most efficient HW based h.264 encoder. I want to transcode multiple 1080p (6-12 mbps bitrate source) TS streams. I will probably use couple of those SoC's. I was reading about Allwinner V3S (~3$ per CPU) based SoCs but can't find any cheap one for sale based on that chip. Also I don't really know what kind of performance this cheap have for HW h.264 encoding. Anyone have any experience with HW 1080p encoding on SoCs? Any suggestions? Edited September 6, 2018 by k0los

k0los Posted September 8, 2018 Author Posted September 8, 2018 hello martos, interesting links. Especially that kickstarter campaign, from what I see they need 11k euro more to start implementing h.264 encoding for Allwinner VPUs, Rockstar based android boxes look interesting and cheap, you could get board out of them, they are <15$. Wonder what kind of encoding performance do they have.

gounthar Posted October 20, 2019 Posted October 20, 2019 Sorry if I hijack the thread, I hesitated with creating another one. I am still struggling with the OrangePi RK3399 regarding the h.264 encoding of the HDMI-IN and the camera. For the time being, I use a hardware h.264 encoder (TBS2605), but still have the project to use ARM SoCs running Armbian. I've seen other threads on other SoCs able to do hardware encoding, so I was wondering if we could make a table with all the information regarding h.264 encoding and transcoding on various SoCs and SBCs more or less handled by Armbian. h.264 encoding boards Name h.264 decoding h.264 encoding h.264 transcode Tests done on Armbian OrangePi RK3399 Y N N N (OrangePi Debian) What do you think of my proposal? Thanks.

Expand That is a good idea but I comes with the burden of the maintenance. Alternative option is that we add three badges H264D H264E H264T under "Specifications" at download pages and give you access that you can do that? 1

On 10/25/2019 at 8:53 PM, martos said: what is your linux ? Expand As already stated to have all features out the box you need at least kernel 5.4.0-rc1. The rootfs distribution does not really matter as long as it provides software of the latest mainline releases. I tinker with cubox-i and hummingboard and as I wanted all bells and whistles I chose the quad variant with 2GB ram for me. This is working for me since round about fedora 26. OK, in the early days many of early adopter patches were required. But nowadays only proper configuration is necessary.

Just composed my first transcode pipeline, see transcode-pipeline.pdf for reference. I do not really know what I am doing (google was my friend) and there are so much knobs for configuration and fine tuning so YMMV. transcode-pipeline.pdfFetching info... 1
