omxh264dec does not decode 25fps

[henryco]

Hello ,

I have the following pipelines that work correctly

sender

gst-launch-1.0 -v ximagesrc display-name=":0" use-damage=false ! queue  !
videoflip method=5 ! videoconvert  ! videoscale ! "video/x-raw, height=768,
width=1360,
framerate=(fraction)30/1,format=(string)I420,force-aspect-ratio=(gboolean)true"
! queue ! x264enc key-int-max=15 pass=pass1 tune=zerolatency qp-max=15
ip-factor=2 speed-preset=veryfast  intra-refresh=true ! queue ! rtph264pay 
pt=96 ! udpsink host=192.168.1.14 port=5000 

receiver

 gst-launch-1.0 -v udpsrc port=5000 caps="application/x-rtp,
media=(string)video, clock-rate=(int)90000, 
encoding-name=(string)H264" ! rtpjitterbuffer ! rtph264depay ! queue !
h264parse ! queue ! omxh264dec ! 
queue ! eglglessink

but the receiver fails if i chose a framerate different from 30/1

(many buffer drops)
may be it's necessary to indicate to receiver also the framerate but i dont
know which element should do that...

also if someone could tell what the preset veryfast means in terms of more
basic parameters ... (?)

thanks in advance
Fred
