fastforward key is not properly recognized of my Belgacom-BGC TV V4 remote

I have created Belgacom-BGC_TV_V4.lircd.conf but this file doesn't properly recognize the fast forward key.

So when pressing the fastforward button it recognizes it as the play key instead of the fastforward key.

Also notice that unlike the other keys I couldn't record that key using irrecord !

Maybe I should manually update Belgacom-BGC_TV_V4.lircd.conf based on the raw output (see below) produced by mode2 command.

sh-4.4# mode2 --driver default --device /dev/lirc0

manual update didn't fix it !
Maybe I have chosen the wrong part (I have chosen the last part).

another approach:

  1. raw recording of several key strokes
  2. aligning them based on gaps
  3. check for same number after gap
  4. identify median pulse value.
  5. identify median value gap (must be 0 or 1)
    6....
