When i used these commands,
$ ffplay -vlowres 1 Mahi-Ve.avi
or
$ ffplay -vlowres 2 Mahi-Ve.avi
Following is the output:

0
Still screen is black.

But when i converted
$ ffmpeg -i Mahi-Ve.avi -r 10 out1.avi
$ ffmpeg -i WLAN_Bluetooth_demo.wmv out2.avi
and played using these commands
$ ffplay -vlowres 1 Mahi-Ve.avi
or
$ ffplay -vlowres 2 Mahi-Ve.avi
it plays well.
What could be possible reasons for this ? Why is that the file plays well
with low bitrate and low resolution,and not with the actual resolution and
bitrate ?
Thanks for your precious inputs.
