[MEncoder-users] WMV to FLV problem with video

Mon Jan 12 18:30:23 CET 2009

Ok, I dont have ffmpeg, I have mplayer, I just played the video and the
output is this:

C:\MPlayer>mplayer Video.wmv
MPlayer 1.0rc2-4.2.1 (C) 2000-2007 MPlayer Team
CPU: AMD Turion(tm) 64 Mobile Technology ML-32 (Family: 15, Model: 36,
Stepping: 2)
CPUflags:  MMX: 1 MMX2: 1 3DNow: 1 3DNow2: 1 SSE: 1 SSE2: 1
Compiled with runtime CPU detection.

Playing Video.wmv.
ASF file format detected.
[asfheader] Audio stream found, -aid 1
[asfheader] Video stream found, -vid 2
VIDEO:  [MP43]  320x240  24bpp  1000.000 fps    0.0 kbps ( 0.0 kbyte/s)
==========================================================================
Opening video decoder: [ffmpeg] FFmpeg's libavcodec codec family
Selected video codec: [ffdivx] vfm: ffmpeg (FFmpeg DivX ;-) (MS MPEG-4 v3))
==========================================================================
==========================================================================
Opening audio decoder: [ffmpeg] FFmpeg/libavcodec audio decoders
AUDIO: 22050 Hz, 2 ch, s16le, 32.0 kbit/4.54% (ratio: 4005->88200)
Selected audio codec: [ffwmav2] afm: ffmpeg (DivX audio v2 (FFmpeg))
==========================================================================
AO: [dsound] 22050Hz 2ch s16le (2 bytes per sample)
Starting playback...
VDec: vo config request - 320 x 240 (preferred colorspace: Planar YV12)
Could not find matching colorspace - retrying with -vf scale...
Opening video filter: [scale]
VDec: using Planar YV12 as output csp (no 0)
Movie-Aspect is undefined - no prescaling applied.
[swscaler @ 00D4AEB0]SwScaler: using unscaled yuv420p -> rgb32 special
converter
VO: [directx] 320x240 => 320x240 BGRA

Also, how could I find out this fps option if I am doing the convertion in
the server after users upload video files?
