For each tuner/demod (adapter) in your setup you can capture an entire channel transport stream with all its virtual/sub channels with something like this:<br /><br />gst-launch-1.0 dvbsrc frequency=503000000 delsys=atsc modulation=8vsb bandwidth=AUTO ! filesink location=capture.ts<br /><br />You can specify what adapter to use by passing a number to dvbsrc:<br /><br />gst-launch-1.0 dvbsrc adapter=0 ...<br /><br />You can get the necessary tuning parameters from the channels.conf file you created with dvbv5-scan.<br /><br />This example is again using ATSC but you get the idea.<br /><br />Hope it helps!reynaldohttps://www.blogger.com/profile/13415907051020449270noreply@blogger.comtag:blogger.com,1999:blog-6712537364188853874.post-80315075928299743142021-05-14T03:31:12.974-07:002021-05-14T03:31:12.974-07:00Can it handle getting more channel from a multiple...Can it handle getting more channel from a multiplex at once ?<br /><br />I used to have a set-top box with two tuners, but you could record two channels and watch a third as long as it was within a multiplex being used by one of the two recorders.<br /><br />I bought 4 dual USB Digital TV tuners, which is more than enough to cover UK TV, any idea how I can set this up to record every channel to a buffer, but then also be able to extract any program from that buffer ?stuaxohttps://www.blogger.com/profile/08755227063937859112noreply@blogger.com
