I wrote a python app on raspbian wheezy ver Sept. 2012 where rtmp streams are read from TV urls to be displayed via omxplayer piped in from rtmpdump - r theurl .. | omxplayer /dev/stdin.
The memory split is 128-128. What happens is that omxplayer aborts with segmentation fault after correctly interpreted the stream from /dev/stdin.
If I save the rtmpdump output in a file then that file can be played by omxplayer without any problem.
Any idea on this issue? Has anybody tried something like this?
