[QUOTE="frag999, post: 309472, member: 62830"] Big_Kev, Sounds great. My suggestion would be to leave the VLC as separate because there are tons of variables for transcoding that can be changed to optimize ones experience. Due to this complexity you might avoid a lot of issues by leaving it up to each user to define this. With that being said, here is what I can use for VLC to transcode across the internet from Mediaportal: this is the input from tvserver: rtsp://192.168.2.152/stream5.0 this is the streamout that I use for transcoding: :sout=#transcode{vcodec=mp2v,vb=500,scale=0.5,acodec=mpga,ab=128,channels=2}:duplicate{dst=std{access=http,mux=ts,dst=192.168.2.152:8081}} -this setting gives a 50% reduction in frame size (scale=0.5), transcoded to mpeg2 video at 500kbit/s and mpeg audio at 128kbit/s. It plays ok over a 1Mb upload cable modem. This is for a Mpeg-TS container/output 192.168.2.152 is the IP of [I]my[/I] TV server "stream5.0" is due to the fact that my dvb card is device #5 in my TV server configuration 192.168.2.152:8081 is the port that VLC is serving to - I have a DNS service so I point my client player to [url]http://XXXXX.myvnc.com:8081[/url] where XXXX is my personalized choice that I got through No-IP.com (free DNS here) A few problems I have ran into: 1. "stream5.0" is a TS file saved during timeshifting. If you change channels, the timeshift file does not erase itself so if you restart your client player, it will go to the beginning of the timeshift file and not to the current position of the timeshift file. This probably could be worked out if I studied it more. 2. I personally get around problem #1 by using mytheatre as my DVB-S tuning software that interfaces with a DVB-T driver emulator that MP TVserver "tunes". So, I actually pickup a UDP stream from Mytheatre. 3. Better video quality could be output if VLC would do h264 conversion better, but I guess the current windows version 0.9.2 is having troubles here. This is another reason I would leave the VLC part out of the solution at this point... Thanks Big_Kev for taking the time to incorporate my request.:thx: [/QUOTE]
