[Live-devel] Error in Outputting mp4 format file

You didn't explain how you redirected 'stdout' to a file, but if you do it on the command line in the usual way - e.g., 
	./openRTSP -4 -d 20 rtsp://184.72.239.149/vod/mp4:BigBuckBunny_115.mov > outputFile.mp4
then things should work OK.  The basic issue here is that the file written to by "QuickTimeFileSink" has to be 'seekable', because ".mov"/".mp4" files contain header information near the start that can be filled in only when the stream ends.

Alternatively, if that doesn't work, you could modify your copy of "playCommon.cpp" to change the call to "QuickFileFileSink::createNew()" (on line 686) to use your output file name, instead of "stderr".
