I get the message ""Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument"" and there is a strange setting 1/90000 in both the output's video and audio stream instead of 1/25 (video, PAL) & 1/48000 (audio). It worked with an older version of ffmpeg but I cannot tell you since when this problem exists. I tried both commands: {{{ ffmpeg -input.avi target pal-dv output.dv ffmpeg -i input.avi -map 0 -f dv -pix_fmt yuv420p -r 25 -ar 48000 -ac 2 output.dv }}} Here's what I have for you {{{ ffmpeg version N-49166-g205b2d2 Copyright (c) 2000-2013 the FFmpeg developers built on Jan 23 2013 13:40:58 with gcc 4.4.5 (Ubuntu/Linaro 4.4.4-14ubuntu5.1) configuration: --enable-gpl --enable-ffplay --enable-libfaac --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libtheora --enable-libvorbis --enable-libx264 --enable-nonfree --enable-postproc --enable-version3 --enable-x11grab libavutil 52. 15.100 / 52. 15.100 libavcodec 54. 90.100 / 54. 90.100 libavformat 54. 61.103 / 54. 61.103 libavdevice 54. 3.102 / 54. 3.102 libavfilter 3. 33.100 / 3. 33.100 libswscale 2. 2.100 / 2. 2.100 libswresample 0. 17.102 / 0. 17.102 libpostproc 52. 2.100 / 52. 2.100 Splitting the commandline.
