Thanks for the tip. However, I'm not using ffmpeg to encode. I'm not 
sure if you are suggesting options for the encoding or the decoding process.
My camera encoders to mpeg4 itself and has very low delay. I'm just 
trying to play with ffplay, also with low delay.

It looks like (from the man page) that low_delay is only an encoding 
option for motion encoding or something - but I could be wrong.

Can you elaborate, perchance?

Thanks & have a great day,
