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.
