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

mac_l1

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 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.

mac_l1

Attached zip file with two files in it (one binary, one shell script).
Use the script to capture the screen, the recording is stopped by pressing a key:

1. ./screenrecord_h264.sh test.mp4

Copy the code

You should have installed machybris before, and also avconv (sudo apt-get install libav-tools).

Every frame is captured from framebuffer device /dev/fb0. Using shared memory this RGB frame is converted to YUV420SP / NV21 format using the RGA hardware module. This YUV frame is then given to the encoder using the raw vpu api that generates an h264 bitstream. After key-press this h264 bitstream file is then encapsulated into a movie-container (mp4 in this case) by avconv utility.

You can see some android logging by:

1. sudo /system/bin/logcat

Copy the code

You can see some kernel logging by:

1. sudo tail -f /var/log/syslog

Copy the code

Hope this helps.


Cheers -- mac_l1

Here is the source code:

i can't find why this PPS id is bad. I try to download last ffmpeg sources... and same problem.
...

just to check: does kodi (installed by mackodi) play the movie correctly?
about the colors: i guess it has to do with some special alignment for rockchip hevc vpu frames (stride and slice height). see my post on freaktab: http://freaktab.com/forum/tv-player-support/rk3288-devices/530835-how-to-realize-rk3288-hevc-h265-hw-decoder-under-linux?p=536311#post536311

Ok... Have you installed dual boot  so you can also check with android kodi or other player how the output is?
Or maybe you can send me a link to the movie file so i can check for myself whats  wrong?

I have single boot with Linux on  eMMC. But when i try with Android (on SD card), it's working perfe ...

When playing on Android: is that on lollipop or kitkat (as they have different video libs)? and is that using kodi? what kodi version?
