[BUG] Collect key frames does not work

[Selur]

Tried to reproduce with your file,..
Log shows "Grabbing key frame positions from current video stream for better cut support on passthrough,..."
Hybrid does call:

ffmpeg -i C:\Users\Selur\Desktop\Test.mp4 -vf select="eq(pict_type\,PICT_TYPE_I)" -vsync 2 -loglevel debug -an -sn -f null -

And from the output (see attachment) there is only one IDR frame in the stream.
All other I frames are non-IDR frames and thus no key frames.

[Parsed_select_0 @ 000002697ff98e80] n:46.000000 pts:46046.000000 t:1.534867 key:1 interlace_type:P pict_type:I scene:nan -> select:1.000000 select_out:0
[h264 @ 0000026901533f00] nal_unit_type: 1(Coded slice of a non-IDR picture), nal_ref_idc: 2

-> so I don't see a bug here.
