channel change/format change

[jacques.facquet@…]

I use tuner and SVideo Input, when I start from tuner (SECAM), its ok, if I change for SVideo (PAL) its ok, if I come back to tuner mythtv say to the driver to change in PAL format (not ok), I have to patch ivtv driver to put secam in the format. I have done some tests with mythtv/trunk but stopped when I was even disabled to use SVideo input, so, I don't know if it works with recent revision (less than 2 months). The format change seem to be late on the channel change.

[Isaac Richards]

Can someone translate this into english, please? I'm not understanding the problem.

[jacques.facquet@…]

sorry, I'll try. The tuner is in SECAM, the SVideo input in PAL. I can record in SECAM on the tuner, then in PAL on SVideo input, but, then if I want record on tuner again, mythtv want record in PAL.

[danielk]

Can you reproduce this with the latest SVN?

Also what is the global format? SECAM or PAL? What are the formats of the two channels?

If this bug still exists, please attach a backend log with "-v record,channel" where you switch from SECAM->PAL->SECAM where it fails on that second switch.

BTW to use the SVideo input you probably need to attach a source to that input with a single channel in the video mode you need.

[jacques.facquet@…]

Can you reproduce this with the latest SVN?

worst with the latest unstable svn : SVideo/PAL Input #0: 'Composite 0' Input #1: 'Composite 1' Input #2: 'Composite 2' Input #3: 'Composite 3' Input #4: 'Tuner 0' Input #5: 'Composite 4' Input #6: 'S-Video 0' Input #7: 'S-Video 1' Input #8: 'S-Video 2' Input #9: 'S-Video 3' Channel is correct.

changing for tuner SECAM :

Channel(/dev/v4l/video0)::SwitchToInput?(in 4): Error -1 while setting video mode 'PAL' (v2), "Périphérique ou ressource occupé", trying v4l v1 Channel(/dev/v4l/video0)::SwitchToInput?(in 4): Error -1 while setting video mode 'PAL' (v1): Périphérique ou ressource occupé TVRec(1) Error: Failed to set channel to 1. Reverting to kState_None TVRec(1): Changing from WatchingLiveTV to None

That's all :-(

Also what is the global format? SECAM or PAL? What are the formats of the two channels?

Global format is SECAM. format for tuners channels is SECAM, for SVideo channels is PAL.

If this bug still exists, please attach a backend log with "-v record,channel" where you switch from SECAM->PAL->SECAM where it fails on that second switch.

As you can see, if I switch to PAL mythtv want switch to SECAM, and if I switch to SECAM, mythtv want switch to PAL ..... I have a patch to force SECAM format on tuner, so, It's working fine but ... I have tried a code which force SECAM when I reveive PAL or SECAM when I receive PAL, it's working too :-(

BTW to use the SVideo input you probably need to attach a source to that input with a single channel in the video mode you need.

Yes, it's a dummy channel with PAL format.

(In [7597]) References #427.

This makes Channel::SwitchToInput?() set the video format based on the channel video format when it is asked to set the channel rather being told to just switch to the input.

I think the problem may have been that SwitchToInput?() was failing because the default format was invalid for the input, so it never got to the point of setting the correct format when it set the channel.

[bjm <bjm@…>]

[7597] breaks ToggleInputs?. When pressing "C" playback freezes on the last frame from the current input. After several seconds the a dialog is displayed for "Error was encountered while displaying video.". "Return to menu" goes back to a black screen rather than the menu. After several more seconds a popup says "The connection to the master backend server has gone away for some reason.. Is it running?". The MBE process is running but cannot be contacted even after restarting the frontend.

Can you try it again, I just checked something in that may fix it...

[bjm <bjm@…>]

Verified fix for the ToggleInputs? issue. I can't speak to the original format change issue.

One nit; UpdateOSDInput() is not called to display the card number and input as it should when changing inputs on the same card with TOGGLEINPUTS. It is, however, still correctly displayed when changing cards with SWITCHCARDS and when starting live TV.

Jacques, I'm going to close this ticket now.

I tried setting my S-Video input to PAL, and it seemed to be doing the right things when switching. If this is still a problem for you, reopen the ticket with logs using the new code...
