Allwinner H618 Hardware-Accelerated Video Decoding & Encoding

[DK1991]

 

Hello dear comminuty,

 

I have spent the last few days trying to get Hardware-Accelerated Video Decoding Encoding to work on the H618.

 

I have tried everything but it does not work.

 

ffmpeg -input_format mjpeg -video_size 1920x1080 -i /dev/video1 -c:v cedrus264 -f rtsp rtsp://localhost:$RTSP_PORT/$MTX_PATH

my goal is to output a rtsp stream from a camera.

But I get this ERROR: 

[cedrus264 @ 0xaaaae53e5170] VE Open error.

Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

sudo ffmpeg -f v4l2 -video_size 1280x720 -i /dev/video1 -c:v cedrus264 -pix_fmt nv12 test1.mp4

It was a hard way for me to get compile FFmpeg with Cedrus

I have to say that I am new to Linux. Therefore I hope that someone can give me a detailed instruction on how to finally get it running.

otherwise I despair of this project
