 -help                        : print this help message

NB: You can define up to 8192 zones via both the -zones and the -z[qw] options as needed.

I assumed:

"I:\Hybrid\64bit\ffmpeg.exe" -y -loglevel fatal -i "F:\TestClips&Co\files\test.avi" -map 0:0 -an -sn -pix_fmt yuv420p -f rawvideo - | "I:\Hybrid\64bit\xvid_encraw.exe" -cq 3 -w 640 -h 352 -csp i420 -framerate 25 -o "E:\Temp\test.m4v"

should work, but it only gives me:

xvid_encraw - raw mpeg4 bitstream encoder written by Christoph Lampert

xvidcore build version: xvid-1.3.7

Detected 16 cpus, using 16 threads.
   -1: key=0, time=      0, len=      -5 | type=I, quant=  0, len=       0

Tot: enctime(ms) =   0.00,               length(bytes) =       0

N frames:      1 frames, size =       0/      0

as output.
The ffmpeg decoding part works fine. (saving to a file instead of piping properly saves yuv data)
I tried '-csp yv12', which didn't help.
I tried adding '-type 0', which didn't help.
I tried adding '-i stdin' or '-i -' but those aborted with 'Error opening input file stdin' and 'Error opening input file -'.

=> Does anyone know how to use xvid_encraw with pipe input?

Ps.: I know when doing no filtering and the input is avi, directly using xvid_encraw might work, but I'd like to use vspipe and ffmpeg to pipe content to xvid_encraw.
