Because we are looking for digital video decoder not analog, so it is possible to get a copy of the decoder memory having decoded frames if we use this gold card. Just we want to make a copy and we will not modify the buffer anymore. > > Thanks & Regards, > Suresh.S Suresh S wrote: > Hi, > > If I am using FusionHDTV 5 RT gold card as a DVB card, then what are the decoders available (what decoders generally the peoples are using nowadays).

There is no decoding in hardware nor kernelspace. The application handles the decoding in userland. For information about the mpeg decoding, look into mplayer, libmpeg2 or ffmpeg. Side note: I would appreciate it if you would stop sending the same question to me in private over and over again. There is a mailing list for these questions (cc added) ... Asking the same question multiple times is not going to change the answer -- there is no hardware decoder on these pci boards, and we do not decode the stream in kernelspace -- it all happens in userland. I hope this helps. Mike _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
