Hi, Thanks a lot for all of your help. I had to upgrade libtool and autoconf. Then the build went smoothly. But when I tried yuvdenoise, I got an memory allocation error. Below I include the output. The y4mscaler part of the pipe can be omitted in order to reproduce the problem. I included it because it contains all informations about the video stream: [EMAIL PROTECTED]:/usr/local/xcdroast/MJPEG > lav2yuv final01.eli |yuvdenoise | y4mscaler -I active=692x564+8+4 -S option=cubicCR -O preset=svcd | yuvplay INFO: [yuvdenoise] ======================================================== INFO: [yuvdenoise] Y4M2 Motion-Compensating-YCrCb-Denoiser INFO: [yuvdenoise] ======================================================== INFO: [yuvdenoise] Version: MjpegTools 1.6.2 ++ WARN: [lav2yuv] unspecified sample-aspect-ratio --- taking a guess... **ERROR: [yuvdenoise] malloc failed INFO: [y4mscaler] Input Stream Header: INFO: [y4mscaler] <<< frame size: 704x576 pixels (608256 bytes) INFO: [y4mscaler] <<< frame rate: 25/1 fps (~25.000000) INFO: [y4mscaler] <<< interlace: top-field-first INFO: [y4mscaler] <<< sample aspect ratio: 59:54 INFO: [y4mscaler] SVCD output format requested in PAL/SECAM norm.
