Sorry for my failure to read thoroughly... Okay, I think I'm doing it
correctly now. Here's what I get.
First terminal window:
$ mkdir -m 0755 /tmp/fifodir_28317/
$ /bin/nice -n19 /usr/bin/mythtranscode --showprogress -p autodetect -c 1004 -s 2006-12-19-21-55-00 -f "/tmp/fifodir_28317/" 2>&1
Second terminal window:
$ /bin/nice -n19 ffmpeg -f rawvideo -s 720x480 -r 29.970 -i /tmp/fifodir_28832/vidout -f yuv4mpegpipe - 2> /dev/null | /bin/nice -n19 yuvdenoise 2> /dev/null | /bin/nice -n19 ffmpeg -threads 4 -y -f s16le -ar 48000 -ac 2 -i /tmp/fifodir_28832/audout -f yuv4mpegpipe -s 720x480 -aspect 1.33333333333333 -r 29.970 -i - -aspect 1.33333333333333 -r 29.970 -deinterlace -croptop 10 -cropright 14 -cropbottom 10 -cropleft 14 -s 320x240 -vcodec mpeg4 -b 960 -lumi_mask 0.05 -dark_mask 0.02 -scplx_mask 0.5 -mv4 -part -vtag divx -acodec mp3 -ab 128 -f avi './Star Trek- Voyager - Caretaker.avi' 2>&1

Stream mapping:

Unsupported codec for output stream #0.1
Then in the first window the process goes and appears to complete to
100%. All I get is a 0 byte file. I'm trying this one using the divx
codec. I have divx4linux package installed.
How do I get ffmpeg to recognize divx?
I also tried asf (using the default settings) and I get:
[msmpeg4 @ 0x84db2d8]multi threaded encoding not supported by codec
Error while opening codec for output stream #0.0 - maybe incorrect parameters such as bit_rate, rate, width or height
Right now I'm trying it using XviD and the eta is over 9 hours. This is
on a dual Xeon 2Ghz machine.
I'm using nuvexport-0.4-0.20061203.svn.noarch.rpm. I would also like to
try MP4 but it looks like I need to download the source and build that
to enable it. I guess I'd like to get asf and divx working before
reinstalling from source and enabling it.
Suggestions are appreciated.
Thanks,
James
