I know if I set a PES FILTER and mark as DMX_OUT_TS_TAP flag, then I can read the filtered stream from dvr device. But now I want to record all PIDs instead of a specific one. How to achieve this? Is it possible to open demux device without set any filter? Thanks in advance!

As Kurt said, if you set pesfilter with output as DMX_OUT_TS_TAP and pass the pid, it will record the streams corresponding to that pid. So, if I pass audio and video pid, then it will record only the audio and video streams. I wanted to know how to record the DVB SI/PSI tables corresponding to the streams I'm recording. Do I have to pass the pids of the tables I want to record or is there some other way? Right now, I'm using the pid value 0x2000 for setting pes filter which is proving to be computationally intensive and consuming lot of CPU. Please help.

With this you'll be able tou watch the video and hear the audio. If you need more tables you should read iso-13818-1, and en 300 438 Cheers -- CAND Frederic Product Manager ANEVIA _______________________________________________ linux-dvb mailing list linux-dvb@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb ^ permalink raw reply [flat|nested] 10+ messages in thread
