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!

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.

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

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

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.
