Seems stream 1 codec frame rate differs from container frame rate: 1000.00
(1000/1) -> 10.00 (10/1)
Input #0, asf, from '/videos/VIZ1.WMV':
Duration: 00:04:57.1, start: 0.000000, bitrate: 8 kb/s
Stream #0.0: Audio: wmav2, 11025 Hz, mono, 8 kb/s
Stream #0.1: Video: MSS1 / 0x3153534D, 640x480, 10.00 fps(r)
PIX_FMT_YUV420P will be used as an intermediate format for rescaling
Output #0, flv, to '/videos/myfile.flv':
Stream #0.0: Video: flv, yuv420p, 320x240, q=2-31, 0 kb/s, 15.00 fps(c)
Stream mapping:
Stream #0.1 -> #0.0
Unsupported codec (id=0) for input stream #0.1

Please help!!! I am badly in need of an solution.

Meena

Since you appear to be running Linux, you would likely get more answers in our Linux Forum. ffmpegX is the Mac version of the program. Moving you.

Hello,
WMV is a tricky format to convert for many converters because of the variable bitrate in the audio and video streams not to mention since it is a proprietary Windows format ffmpeg developers have to be careful in regard to licensing and drm issues and therefore are not able to support WMV handling as well as other non-proprietary formats.

Having said that, looking at your command line I would suggest you try it without the "-sameq" command. Also many of the latest ffmpeg SVN versions have changed their command syntax, For instance instead of the video Codec being identified as "-vcodec h264" some of the latest versions require "-vcodec libx264". I'm only guessing here but if possible you might want to revert back to an older build of ffmpeg and try your commands there. All I know is if you find a version of ffmpeg that works, hold on to it for dear life, all it takes is one small syntax change to make it useless.

There is a great little ffmpeg GUI front end called WinFF that works in Linux and Windows, it won't solve your problems if the ffmpeg SVN is at fault but over a good build it has many great presets for converting pretty much anything.
