From b6ecf8bb4e0fbda10f41770187e2120c282770f4 Mon Sep 17 00:00:00 2001 From: Antti Palosaari Date: Tue, 29 May 2012 12:17:20 -0300 Subject: [PATCH] [media] dvb_usb_v2: add .get_ts_config() callback Add new callback in order to resolve used TS (MPEG transport stream) configuration. Normal TS is 188 byte payload only but there is currently 204 byte TS and raw TS supported too. Traditionally TS type was mapped as a frontend property but it does not work no longer after we changed from MFE (multi-frontend) to SFE (single-frontend). So it is not possible to map TS for the given FE as there could be only one FE instead of multiple.
