Hardware decoder on linux for firefly-rk3288(source opened)

isle

This is how to add hardware decoder to ffmpeg on linux for firefly-rk3288.

First, choose the vpu driver librarys.
We use the hybris library made by mac_l1,also you can choose rockchip's vpu driver library ,which they has put it on a websites.
For convenience ,I put a mac_l1's hybris lib's copy to "baidu pan". here is the link:
http://pan.baidu.com/s/1pKdqUQR


Install the driver library:

1. sudo dpkg  -i machybris-0.1.0_armhf.deb

Copy the code

if you get a mistake. please run this:

1. sudo apt-get -f install

Copy the code

and try again.

After install done ,reboot your board .

Install dependencies library :

1. sudo apt-get install libsdl-dev

Copy the code

this source code need compiled on the development board. if you want to compiled on PC ,you need modify the source code.

Install compile environment:

1. sudo apt-get install build-essential

Copy the code

Get the source code:

1. git clone https://github.com/isle0118/firefly-vpu-linux.git

Copy the code

Compile and Install:

1. ./configure  --enable-shared --prefix=/usr --disable-ffmpeg --disable-ffprobe --disable-ffserver  --disable-static

Copy the code

1. make && sudo make install

Copy the code

Now, you can test the hardware decoder with ffplay .

the source file is here :

1. libavcodec/rkdec_decoder.c

Copy the code

if you want use other driver library or compiled on PC ,just need to modify this file.


Have fun !

Wow! I am impressed!

This opens up the way to get hw decoding in chromium, mplayer and vlc, as they all use ffmpeg/ avcodec as base.
Maybe we can even play netflix on chromium!

Also a new version of machybris (0.1.1) can be downloaded here: http://www.mac-l1.com/v0.1.1/mac ... 4.2-0.1.1_armhf.deb

Great work, isle!

your machybris is Amazing。we can do many things on it.

we really appreciate all your work!

Hi mac_l1:
can you share the method that how to use GPU for encoding?

Hi,
See: https://github.com/mac-l1/machyb ... 64recorder.cpp#L158.
I used this code to capture the screen into a h264-movie using vpu.
This can probably quite easily be added into the shared ffmpeg / avcodec code above from isle.

Hi,

I get an error : librk_on2.so and libvpu.so are missing !

I think a package is missing....

fd101283

OK it's solved with just a reboot .....
Do you know why it's not working with 4K video ?

isle

the vpu can decode 4K video smoothly. But the display was terrible.
so we didn't add 4k support here.

fd101283

Oh bad news.....
It's not possible to add 4K support (maybe with display improvement) ?

I think that the main advantage of this chip is 4K support.

Hi mac_l1:
can you give me screenrecoderh264 for testing HW encoder
