@v0lt:
If the encoder supports it, you should -- but you'll have to drive it manually, same as usual.
@Gromozeka:
Not for this pass.

There's a lot more required than just UI work.

Phaeron, you can do work port from ffmpeg to other encoders?
External encoders\ffmpeg
-f rawvideo -s %(width)x%(height) -i - -f yuv4mpegpipe - | mencoder.exe (xvid_encraw.exe, mpeg2enc.exe and other) |

I understand.
Still, I unloaded the pictures. For the future. Maybe 
This is only an idea. But I have not brought it to the end.
One of the variants turned out like this.

No. The pipe that you're using is a feature of the command processor (cmd.exe), and it's not as simple in this case because I need to maintain the pipes and monitor all of the processes involved. That's a lot more work and complexity than I want to take on at this time.
Why are you trying to pipe multiple processes, btw?

Because Virtualdub without ffmpeg not pipe to mencoder.exe, xvid_encraw.exe
Hcenc - best mpeg2, but not eat pipe
P.S: Phaeron, why this not work?
External encoders\xvid_encraw.exe
-type 0 -csp yv12 -single -cq 3,0 -smoother 0 -vhqmode 4 -masking 2 -max_key_interval 250 -quality 6 -vhqmode 4 -qtype 0 -noclosed_gop -max_bframes 1 -bvhq -bquant_ratio 100 -bmin 4 -bmax 10 -avi "%(tempvideofile)"
xviD_encraw here:
http://rapidshare.com/files/388850573/xvid...encraw.rar.html
Input options:
-i string : input filename (stdin)
-type integer: input data type (yuv=0, pgm=1, avi/avs=2)
-w integer: frame width ([1.2048])
-h integer: frame height ([1.2048])
-csp string : colorspace of raw input file i420, yv12 (default)
-frames integer: number of frames to encode
Output options:
-dump : save decoder output
-save : save an Elementary Stream file per frame
-o string : save an Elementary Stream for the complete sequence
-avi string: save an AVI file for the complete sequence
-mkv string: save a MKV file for the complete sequence

You're missing the parameters to set width/height/framerate/frame count, but even then I can't get this build to take a stdin stream properly. It just keeps encoding 0 frames.

This parameters unnecessary
this parameters work fine from comand line:
| CODE | | xvid_encraw.exe -i 1.avs -type 2 -single -cq 3,0 -smoother 0 -vhqmode 4 -masking 2 -max_key_interval 250 -quality 6 -vhqmode 4 -qtype 0 -noclosed_gop -max_bframes 1 -bvhq -bquant_ratio 100 -bmin 4 -bmax 10 -threads 2 -avi out.avi |

When you pipe raw video, the encoder needs the framesize and fps parameters.

What do you think about the support yuv4mpegpipe? Here are some of the format YUV4MPEG2.
Choosing a input format for Video can do for the tab as well as Audio. |

not? its very good idea, because yuv4mpegpipe support mencoder, mpeg2enc, xvid_encraw and other comand line encoders! but yuv support only ffmpeg and x264
