Hi,

---steps to reproduce:

gst-launch-0.10 -v videotestsrc ! "video/x-raw-yuv, framerate=(fraction)25/1,
format=(fourcc)I420, width=1920, height=1080" ! ffenc_ljpeg buffer-size=2000000
! queue ! ffdec_mjpeg ! queue ! videoscale ! "video/x-raw-yuv, width=384,
height=216" ! identity ! xvimagesink

---error: 

It seems to drop 99%.

---more infos:

It works (no drops) if I replace xvimagesink by fakesink.

gst-launch-0.10 -v videotestsrc ! "video/x-raw-yuv, framerate=(fraction)25/1,
format=(fourcc)I420, width=1920, height=1080" ! ffenc_ljpeg buffer-size=2000000
! queue ! ffdec_mjpeg ! queue ! videoscale ! "video/x-raw-yuv, width=384,
height=216" ! fakesink sync=1

Maybe something is not working with the qos.

(note that I do not know an other decoder than ffedc_mjpeg to decode loss less
jpeg)

Julien
