So... I've made some progress. I can now generate the exact same commands RTMPDumpHelper generates but I cannot get them to work. Whenever I fetch the parameters, compile the command and execute it (either using my program or calling rtmpdump.exe manually) I get the NetStream.Play.Failed error. Weirdly RTMPDumpHelper works...
It look's like this:
Code:
E:\rtmpdump-2.4>rtmpdump -r "rtmp://video466.myfreecams.com:1935/NxServer" -a "NxServer" -f "WIN 16,0,0,305" -W "http://www.myfreecams.com/mfc2/flash/
MfcVideo150223.swf" -p "http://www.myfreecams.com/mfc2/static/player.html?broadcaster_id=0&cache_id=1428445108&target=main" -C N:140083383 -C S: -C N:103423376 -C S:DOWNLOAD -C N:3423376 -y "mp4:mfc_103423376.f4v" -o "CaliGirlxx_2015-04-13_13-11-37.flv"
