Hi, i'm new to ffmpeg and have a very simple problem (checked the FAQ already) I try to encode a mpeg file from a list of images. The frames are PNG-files and named as followed: frame0001.png, frame0001, ... frame2000.png As fare as I understand the man-pages correctly the following line should produce a mpeg file: ---------------------------------------- ffmpeg -i vh%04d.png /tmp/a.mpg ---------------------------------------- But all I get is the following error message: ---------------------------------------- ffmpeg version 0.4.9-pre1, build 4738, Copyright (c) 2000-2004 Fabrice Bellard configuration: --build i386-linux --enable-gpl --enable-pp --enable-zlib --enable-vorbis --enable-a52 --enable-dts --disable-mmx --disable-debug --prefix=/usr built on Feb 5 2005 01:20:01, gcc: 3.3.5 (Debian 1:3.3.5-6ubuntu1) Input #0, image2, from 'vh%04d.png': Duration: 00:01:58.0, start: 0.000000, bitrate: N/A Stream #0.0: Video: png, 300x300, 25.00 fps Output #0, mpeg, to '/tmp/a.mpg': Stream #0.0: Video: mpeg1video, 300x300, 25.00 fps, q=2-31, 200 kb/s Stream mapping: Stream #0.0 -> #0.0 [mpeg1video @ 0x82d0e1c]only YUV420 is supported Error while opening codec for stream #0.0 - maybe incorrect parameters such as bit_rate, rate, width or height ---------------------------------------- The problem seams to be the 'only YUV420 is supported' part. I tried jpg-fiels (like in the man pages) with the same result. Any Hint? Regards, johannes PS: Using Linux/Ubuntu version of ffmpeg.

For the very same purpose I used mlt (http://mlt.sf.net) and it worked quite well. The command line for the inigo tool is: inigo -group in=0 out=20 *png -consumer avformat:/tmp/slideshow.mpeg Bye, Torsten

Thanks for the link but I would really like to use ffmpeg since it comes with my ubuntu installation. MLT is not available in the distribution and I'm already busy compiling and testing my one stuff :) As far as I understand the docu ffmpeg should be able to encode png or jpg images to movie file. Is this true? Regards, Johannes

I think you need to force yuv420p conversion: ffmpeg -i vh%04d.png -pix_fmt yuv420p /tmp/a.mpg
PS: Using Linux/Ubuntu version of ffmpeg.
Always use the CVS version. The releases are always very old. Besides, you''ll not get much help from the MLs unless you use it because lots of issues are already fixed in CVS. /Roine
Hi,

Works, thanks.

Very Old? The Ubuntu version is 0.4.9-pre1 which is the last version I get from the ffmpeg SF-page.
Besides, you''ll not get much help from the MLs unless you use it because lots of issues are already fixed in CVS.
I have read the man-pages, FAQs and Readmes and got the impression, that the current stable ffmpeg version can encode movies from singe images. Therefore people should give me at least a hint if it is already fixed in the CVS version. Thanks again, Johannes
