Thank you very much for your explanation. It worked but with rtmpgw. Its better for me cause it does not use temp files. I do like:
am start -a android.intent.action.VIEW -d
http://127.0.0.1 -f 0x10000000 -n org.videolan.vlc.betav7neon/.gui.video.VideoPlayerActivity
rtmpgw -v -r etc
Only need to figure out how to start this terminal script through a widget.
Thank you very much for providing the port.
