OMXplayer + UDP Multicast video corruption.... - Raspberry Pi Forums

-

hi....

using ffmpeg create h264 multicast live stream of presenter , content (powerpoint slides) trying play on raspberry pi3 using omxplayer....the command using play is:

omxplayer -o both udp://239.255.42.42:5004 --live

stream starts ok presenter full screen, , when switch view powerpoint fullscreen/presenter picture-in-picture, works.

however, when presenter changes slides view on rpi shows top half of new slide , bottom half of previous one....see attached slide....the bottom half of previous slide (which black).

if switch fullscreen presenter view, displayed fine.

have tried try , fix this....changing codecs, bitrates, h.264 profiles etc., can't work.

works fine in vlc, seems point problem omxplayer. have checked network , there appears no problems, no dropped packets etc.

i'd grateful in resolving this.....

if tell me typically causes this, might point me in right direction fixing myself.

also, hope right forum this....if not please point me @ more appropriate one.

muchly in advance.

cacheman.

Valutazione Template - Joomla! Forum - community, help and support

SD Datastring Convention
