h264 encoding demo
Is there a working h264 encoding demo? enc_dec_demo does not seem to compile. It uses older include files (e.g. #include "encoder_type.h") existing in earlier versions of the "old" directory (I think its renamed to type.h)
There is a demo in old directory called "EncoderDemo" which comiles but seems to have issues with the current kernel/board configurations? My debug output gets flooded with disp pixel sequence and or scaler issues. The Display does not show any valid picture/video.
I use an a13-olinuxino board for testing. Thank you, Andreas
Thank you very much! I'll look into that..

Dear developers, Thank you for the demo files. I tried the other demo, but met a problem called Open file /dev/cedar_dev failed. I used pcDuino board with Allwinner A10 CPU. So could you please explain how to solve this problem?
Thank you very much!

Did you check permissions or if the file exists at all?
Did you follow the howto? http://linux-sunxi.org/Cedrus

Yes. I used "root" to run that app and it worked. But I still has some problems about color space. I used YUV420 "foreman.yuv" sequence to test the app and used VLC to check the output file. I fount the color was not right but the Y image was OK now. I need to consider the RAW file format.
Thank you again.
