[MPlayer-users] "mplayer -identify" doesn't output movie aspect

[Louis-David Mitterrand]

Hi,

Before converting a .vob to .flv with ffmpeg my script makes a run of 

	timgad:~% mplayer -really-quiet -ao null -vo null -frames 0 -identify phile.vob
	ID_VIDEO_ID=0
	ID_AUDIO_ID=128
	ID_FILENAME=30_jours_de_nuit.vob
	ID_DEMUXER=mpegps
	ID_VIDEO_FORMAT=0x10000002
	ID_VIDEO_BITRATE=9000000
	ID_VIDEO_WIDTH=720
	ID_VIDEO_HEIGHT=576
	ID_VIDEO_FPS=25.000
	ID_VIDEO_ASPECT=0.0000
	ID_AUDIO_FORMAT=8192
	ID_AUDIO_BITRATE=0
	ID_AUDIO_RATE=0
	ID_AUDIO_NCH=0
	ID_LENGTH=118.08
	ID_VIDEO_CODEC=mpegpes
	Using SSE optimized IMDCT transform
	Using MMX optimized resampler
	ID_AUDIO_BITRATE=192000
	ID_AUDIO_RATE=48000
	ID_AUDIO_NCH=2
	ID_AUDIO_CODEC=a52

so aspect is apparently 0 but when playing the file:

	Movie-Aspect is 1.78:1 - prescaling to correct movie aspect.
	VO: [xv] 720x576 => 1024x576 Planar YV12 

Where is that information contained?

Thanks,
