Do you have a publicly accessible URL I can connect to that shows the problem?

popcornmix avatar Mar 10 '14 14:03 popcornmix

sorry , you could not access to .

chenyayun avatar Mar 10 '14 14:03 chenyayun

Can you run both streams with -g and post (e.g. to pastebin) the omxplayer.log files produced.

popcornmix avatar Mar 10 '14 14:03 popcornmix

yes, I can . I will paste the log file here tomorrow!
