Problem with switching channel with VLC

Added by Florian Eckert about 10 years ago

I have a problem with switching channels.
I have a channel list on my VLC @ Mac. If I switch a channel it does not work. I have to double-click a channel in the list twice to switch the channel. The first double-click does not result in a channel switch.

I have the tvheadend sources from the GIT repository, compiled and installed on my raspberry pi with the raspbian OS.
I use a Sundtec USB stick in DVB-C mode.
VLC client on apple mac.

Does someone hase a good idea? Shall I provide additional information?

Hi Florian,

Maybe check in the debug-log ( bottom of the tvheadend interface, enable debug) if there is any reaction there at the first attempt to switch from VLC.

If there is, what is the message?

Alex.

Ok, here is what I triggered and the debug output:

I activated the debug log level:

Loglevel debug: enabled
Okt 08 21:15:55 eit: processing complete
Okt 08 21:16:15 dvb: "/dev/dvb/adapter0" tuning to "418,000 kHz" (Autoscan)

Okt 08 21:16:15 eit: install table handlers
Okt 08 21:16:16 eit: begin processing
Okt 08 21:16:35 eit: processing cancelled

Now I started VLC and double-clicked one channel in the channel list:

Okt 08 21:17:29 subscription: "HTTP" direct subscription to adapter: "Sundtek DVB-C (III)", network: "", mux: "602,000 kHz", provider: "ARD", service: "Das Erste HD", quality: 100

Okt 08 21:17:29 Service: Sundtek DVB-C (III)/602,000 kHz/Das Erste HD: Status changed to [Hardware input] [Input on service] [Demuxed packets] [Reassembled packets]

No TV-Picture is displayed and the VLC progress bar is scrolling (waiting for transmission)
Now I double-click the same channel again and after round about 1 second I have a TV-picture. Additional the debug log output:

Okt 08 21:19:55 subscription: "HTTP" direct subscription to adapter: "Sundtek DVB-C (III)", network: "", mux: "602,000 kHz", provider: "ARD", service: "Das Erste HD", quality: 100
Okt 08 21:20:00 webui: Start streaming /stream/service/_dev_dvb_adapter0_Sundtek_DVB_C__III_602000000_283d

Now I press the forward button I the VLC control to the next channel:

Okt 08 21:21:36 mkv: Live stream: Write failed -- Datenübergabe unterbrochen (broken pipe)
Okt 08 21:21:36 webui: Stop streaming /stream/service/_dev_dvb_adapter0_Sundtek_DVB_C__III_602000000_283d, muxer reported errors
Okt 08 21:21:36 dvb: "/dev/dvb/adapter0" tuning to "450,000 kHz" (Transport start)

Okt 08 21:21:36 Service: Sundtek DVB-C (III)/450,000 kHz/ZDF HD: Status changed to [Hardware input] [Input on service] [Demuxed packets] [Reassembled packets]

Then double-click on the channel (the TV-Picture is available)

Okt 08 21:21:56 webui: Stop streaming /stream/service/_dev_dvb_adapter0_Sundtek_DVB_C__III_602000000_283d, timeout waiting for packets
Okt 08 21:21:56 subscription: "HTTP" unsubscribing

Okt 08 21:22:40 webui: Start streaming /stream/service/_dev_dvb_adapter0_Sundtek_DVB_C__III_450000000_2b66

Stopping the TV by pressing stop button results to the following debug output:

Okt 08 21:23:39 mkv: Live stream: Write failed -- Datenübergabe unterbrochen (broken pipe)
Okt 08 21:23:39 webui: Stop streaming /stream/service/_dev_dvb_adapter0_Sundtek_DVB_C__III_450000000_2b66, muxer reported errors

Maybe some interesting information is the line:

TS: Sundtek DVB-C (III)/450,000 kHz/ZDF HD: Transport error indicator
