You are causing the video steam to be decoded. You are then scaling the pictures to 720x576 -- Why?
You are then forcing SAR and DAR before sending the pictures to the encoder. Since you don't specify
an encoder, the encoder is probably defaulting to MPEG2.
-crf 0
I've never used this bitstream function. Constant frame rate? Yes, it probably is CFR, but why do
you think you need to force it? Leave that out.
