Subject: much faster service change on same transponder (just FTA)
X-Git-Tag: 2.6.0~3750
X-Git-Url: https://git.cweiske.de/enigma2.git/commitdiff_plain/0b30e9845b60aae63e6d7e5b8e3a80bdfe4e4ad5

much faster service change on same transponder (just FTA)

add ability to "zapto" and "record" services and use just cached pids (no use of PMT) ( no playback yet !!!! )

this is implemented likewise to enigma1
Example entry in lamedb:

6dca:00c00000:044d:0001:1:0
Das Erste
p:ARD,c:000065,c:010066,c:020068,c:030065,f:4

p: is the provider name
c:XXPPPP: are cached pids
  00 is the video pid
  01 is the audio pid
  02 is the text pid
  03 is the pcr pid
f: is a flag bitmask
  bit 3 (decimal 4) is used for disable use of the pmt (just use cached pids)
