Hi guys,

I am getting an error: http://pastebin.com/NrxBq2Ts. But do not know if it's bad code:http://pastebin.com/3nCSh2F0 or unstable kernel.

I am using Ubuntu linaro 12.11 and kernel sunxi-v3.0.76-r0 in cubieboard.

kernel: https://github.com/linux-sunxi/linux-su ... v3.0.76-r0
cubieboard: http://cubieboard.org/

Command: NOTE: cedar is the specific cubieboard decoder: CedarX is Allwinner's multimedia co-processing technology for hardware accelerated video and image decoding, as used inside their A10 SoC's and others. I am using a special port vlc to Allwinner A10. If i use: runs cool!

VLC is unable to convert from the decoder plugin's output format to the video output plugin's input format.

Note that you can obviously not have a custom video output and custom video output callbacks at the same time.

I beg your pardon, but I do not understand.

Do you mean that vlc can playback a video using custom decoder like cedar, but libvlc does not? Because there are lots of callback functions.

If I use another graphical library can work? Like libx11 or libqt. The result is the same?

thanks for your help.

Your code requests RV16 as video output chroma. Your decoder outputs something else. VLC does not know how to convert that something else to RV16.

Now I get it!

You have reason, i changed to 'libvlc_video_set_format(mp, "RV32", VIDEOWIDTH, VIDEOHEIGHT, VIDEOWIDTH*4);' and i get this:

[0x44a37d00] main filter error: Failed to create video filter2
[0x44a363f0] main filter error: Failed to create video filter2
[0x44a34dc0] main filter error: Failed to create video filter2
[0x44a343a0] main vout display error: Failed to create video filter2
[0x44a343a0] main vout display error: Failed to adapt decoder format to display

Thanks for your help and time!
