if source = DVB-T ->output not deinterlaced during transcode

Hello all!
I'm breaking my head trying to properly deinterlace dvb-t input for streaming.
It seems VLC combines two half frames into two separate frames and thus doubling fps and squeezing the resolution by half vertically.
This is the command line I'm using:

Code: Select all

vlc.exe dvb-t://frequency=602000000 :dvb-bandwidth=8 :program=1 :sout=#transcode{vcodec=h264,venc=x264{no-cabac,level=3.0,subme=5,trellis=1,merange=16,min-keyint=25,scenecut=40,ipratio=0.71,ratetol=20k,vbv-maxrate=96k,vbv-bufsize=96k,qcomp=0.6,qpmin=10,qpmax=51,qpstep=4,keyint=30,ref=1,deblock=0:0,aud},threads=2,deinterlace,audio-sync,fps=25,width=300,height=240,vb=800,acodec=mp4a,ab=64,channels=2,samplerate=48000}:std{access=http,mux=ts,dst=0.0.0.0:8080/stream.ts}
Same with VLC 1.01, 1.02 and 1.03.
Any ideas how to solve the problem?

I don't think this is a deinterlace problem: you can set a aspect ratio in client (Video > Aspect ratio > ) and video will be shown correctly. I guess the aspect ratio is given wrong in transcoded stream.

There is known aspect ratio issue with x264 when used with VLC.

Aspect-ratio problem on transcoding should be fixed in 1.1 nightlies
