Kaffeine with VLC backend.

Kaffeine with VLC backend.

[Malcolm Priestley]

Hi Mauro

Have you encountered a strange bug with Kaffeine with VLC backend.

Certain channels will not play correctly, the recordings will also not 
play in VLC.

However, they will play fine with xine player. Only some channels are 
affected of those provided by SKY such as 12207 V on Astra 28.2.

These channels will play fine with Kaffeine with xine backend they also 
play with VLC's dvb-s interface.

Any ideas what could be wrong with the TS format?

I am wondering if SKY are inserting something into the format.

Regards


Malcolm

Just a follow up it appears that the PCR is missing from the stream 
which is transmitted on a different PID.

In the case of the above channel manually adding PID 8190 the backend 
plays normally.

You're likely using an old version of Kaffeine. See this BZ:

Somehow, PCR PID needs to be added to the PID filter.

Unless there is a way VLC can ignore it like xine does?

I suspect that it is probably easier to patch Kaffeine for it to filter
the PCR PIDs and send to libVLC.

Part of the filtering logic is at:
	src/dvb/dvbsi.cpp

Please notice, however, that part of the contents of this file is
auto-generated via tools/updatedvbsi.cpp from tools/dvbsi.xml.
