[FFmpeg-user] Convert MPEG-PS progressive to Interlaced

[kumar vikram]

Hi All,
I have been struggling with converting PS progressive stream to PS
interlaced for my test app.

But all the conversion commands used by me are converting to Frame based
interlaced stream but what I am looking for is I-P field based interlace(I
frame having top filed and next frame having the bottom field) .

Can someone help me with proper command do convert with ffmpeg?

Regards,
Vikram
