Libreelec for rk3328

[Ac2n]

thanks mo123 where can I download this old 4.4 kernel LibreELEC ?
I will try with http://releases.libreelec.tv/LibreEL...2.1-box.img.gz

[Ac2n]

So, http://releases.libreelec.tv/LibreEL...2.1-box.img.gz
boot but don't work so fine..
balbes150 , please can you post the last version of your LE for RK3328 in kernel 4 ? can see in #103

Add new image 20191210 kernel 4 and 5

Please check the operation of different codecs on rk3328 in the latest 20191210 images with kernel 5.

Regarding #120 comments, LibreELEC-RK3328.arm-9.1-devel-20190512173254-bdfaff1-box from http://kwiboo.libreelec.tv/test/old/ is kernel 5.1, not 4.4. :-(

These versions are not updated and are no longer supported.

thanks balbes150 ..

In the link that you give me there is a kernel 4 version of 23-11-2019, I will test this one..
However I can not find the version of 10-12-2019 which seems to be the last made under kernel 4, if someone has keep a copy of this version please share.

Have a nice day..

If you really want the Kernel 4 versions then just use the Official or Alpha images directly from LibreELEC. balbes150 makes Development images so you can use or test the latest and greatest features and code updates available to LibreELEC software.

About the problem of lack of HW acceleration while playing XVID videos in MX10, #114, Kodi says:

CDVDVideoCodecDRMPRIME::Open - using decoder V4L2 mem2mem MPEG4 decoder wrapper
CDVDVideoCodecDRMPRIME::Open - unable to open codec

I'm starting to think that the problem may be in the absence of a node for the RGA device in the DTB of the image, given http://opensource.rock-chips.com/wiki_Rga.

In the dmesg of the stock android kernel, RGA is correctly initialized, as shown next, but not so in the image:

<6>[    1.610403]  [0:      swapper/0:    1] rga: Module initialized.
<6>[    1.611086]  [0:      swapper/0:    1] rga2 ff390000.rga: rga ion client create success!
<6>[    1.611313]  [0:      swapper/0:    1] rga: Driver loaded succesfully

Does this make sense?

This is a completely different core, it is outdated and not used for LE.

Libreelec arm and aarch64 20200416 kernel 5.7-rc1

This is a completely different core, it is outdated and not used for LE.

I see. I'm pasting what I've got just in case it is useful to anyone.

Adding this to the DTS:

    rga@ff390000 {
        clock-names = "aclk", "hclk", "sclk";
        clocks = <2 154 2 340 2 69>;
        compatible = "rockchip,rk3288-rga";
        interrupts = <0x0 0x21 0x4>;
        reg = <0x0 0xff390000 0x0 0x1000>;
        dma-coherent;        
        resets = <0x2 0x8A 0x2 0x8B 0x2 0x88>;
        reset-names = "axi", "ahb", "core";
        status = "okay";
    };

The kernel inits the driver:

[   10.052260] rockchip-rga ff390000.rga: HW Version: 0x04.00
[   10.056743] rockchip-rga ff390000.rga: Registered rockchip-rga as /dev/video0

and lsmod shows:

v4l2_mem2mem           45056  2 hantro_vpu,rockchip_rga

Sadly this does not get me HW accel play of XVID videos.

My current understanding is that the Rockchip rk3328 codec is Hantro G1 compatible, and the mainline driver presently does not handle MPEG4 part 2, ASP (i. e., xvid)

https://github.com/torvalds/linux/tree/master/drivers/staging/media/hantro

(would be great to be shown wrong).

Mainline doesn't support certain mpeg4 currently, it's software decoded.
Only 4.4 kernel with an old mpp_mpeg4_hardware_decoding patch plays mpeg4/xvid correctly, the patch is only in RK322x LE images and MVR9 RK3328 image I made.
The patch is not compatible with 5.7 kernels as mpp is not used anymore and it was switched to v4l2 codec drivers which only supports Mpeg2, VP8. H264 currently and VP9 that was recently added but not in LE yet.
RGA has to do with 2D rendering in Linux and doesn't affect video playback.

Thank you, that is clarifying.

Thank you, that is clarifying.

It is better to post this information on the LE forum so that all LE developers can see it.
