--- Comment #1 from Nicolas Dufresne (stormer) <nicolas.dufresne at collabora.co.uk> ---
One thing I observe is that ffmpeg seems to append a "dummy" frame at the end.
I would need to refer to the spec, but the relevant log is:

gstflvdemux.c:1620:gst_flv_demux_parse_tag_video:<flvdemux0> pushing 115 bytes
buffer at dts 0:00:33.266000000 with duration 99:99:99.999999999, offset 999,
keyframe (0)
gstflvdemux.c:1761:gst_flv_demux_parse_tag_type:<flvdemux0> tag data size is 5
gstflvdemux.c:1382:gst_flv_demux_parse_tag_video:<flvdemux0> parsing a video
tag
gstflvdemux.c:1413:gst_flv_demux_parse_tag_video:<flvdemux0> dts bytes 00 81 F2
00 (33266)
gstflvdemux.c:1432:gst_flv_demux_parse_tag_video:<flvdemux0> got cts 0
gstflvdemux.c:1436:gst_flv_demux_parse_tag_video:<flvdemux0> video tag with
codec tag 7, keyframe (1) (flags 17)
gstflvdemux.c:1521:gst_flv_demux_parse_tag_video:<flvdemux0> Nothing left in
this tag, returning

I would highlight that this is marked as keyframe, but does not contain a NALU.
