Can't get I422 format yuvdata out form VLC??

Hi,

I posted this question to the windows troubleshooting, but now added also here, sorry.

So my problem is, I can't get I422 format yuvdata out from the VLC -player. My version is 1.0.1and I've used these settings:
- video output module: YUV video output
- device fifo or filename: c:\temp\stream.yuv
- used chroma I422 (I420 as a default)

When I checked the logfile, there were a message:

pic out sz 720x576, of (0,0), vsz 720x576, 4cc I422, ar 5:4, sar 1:1, msk r0xff0000 g0xff00 b0xff
main debug: looking for video filter2 module: 20 candidates
main debug: TIMER module_need() : 50.000 ms - Total 50.000 ms / 1 intvls (Avg 50.000 ms)
main error: no chroma module for I420 to I422 i=720x576 o=720x576
main error: video output creation failed

What could be the reason for not having I420=>I422 chroma module??

Thanks!

Did you enable FFMPEG swscale and postprocess supports?

Do you mean: Video PostProcessing filter => FFMPEG post proceccing filter chains? I have there "default" -value.. Quality level is 6.

For swscale I tested bicubic, bi-linear etc.. didin't work.

Please could you tell exactly what filters and where I have to enable. Actually, I didn't even found any separate enable for FFMPEG, but saw many many definitions inside ffmeg.. Always I got a message that chroma filter not found.. :(

thanks for your help.

I think VLC does not support I420 to I422 conversion, in fact.
