program guide (epg) preview window not scaled properly on OS X

[risto78@…]

when displaying the program guide on OS X, the live tv preview window is merely offset but not scaled

the embedded window is shown at the size of the display, so it overlaps the guide and runs past the edge of the screen it looks like the mainwindow viewport is resized instead for some reason

[risto78@…]

it's been a month can we please get this at least assigned to someone who looks at Mac OS Tickets? eg nigel or danielk

[Nigel]

One month? That's nothing. The embedded TV window has been broken in one way or another since the start of the OS X port (thats late 2004). I don't use that feature. Note that assigning it to someone can often mean it is ignored for longer because other devs think "OK, Nigel is dealing with that one!"
Anyway, in trunk, the embedded window scales OK if Live TV is configured to start in the guide, but the guide is never displayed (probably because the clipping region is the size of the entire window?). After exiting the guide, the small embedded window area remains. If normal LiveTV is started, and the EPG is enabled, the window never scales down, and then the TV image stays in the window (i.e. the menu is never displayed after exiting TV). I will examine fixes when I have time (this is a busy few months for me)

[Phil]

I'm seeing this issue also. I went back through Sniderpad's builds and it seems that it first appeard in: 20081110 SVN Revision 19001

20081103 SVN Revision 18900 appears to scale OK.

Also, I don't know if it's related but I'm also seeing Mythfrontend crash every time that the program guide displayed. This also was introduced in the same build.

[Phil]

Sorry for the extra comment - but is there a way to just disable the preview in the guide as a way to work around the scaling and crash issue? I haven't found anything in the setup options for this.

[jyavenard@…]

To disable EPG,

in mythtv/libs/libmythtv/videooutbase.cpp

in function: void VideoOutput::EmbedInWidget?(WId wid, int x, int y, int w, int h)

replace:

if (!allowpreviewepg)

return;

with: if (!allowpreviewepg)

return;

Recompile

(In [20620]) Scale embedded playback window properly. Refs #6211.

[dstrang@…]

I've tested this patch; I can confirm that it works - the embedded playback window does scale, and it doesn't crash MythFrontend anymore.

However, there is a small issue - If you "escape" out of the guide, the playback window does not scale back to the original size.

[anonymous]

I haven't had that occur, but the aspect in the embedded window, and the main window after escaping, can be wrong. There are also occasional crashes when "always display the guide"is set:

Bumping open 0.22 milestone tickets to 0.24

[mythtv@…]

Got EPG Problem after updating to 0.22-fixes from sniderpad:

Going from LiveTV to EPG and back only works with decoder "Standard", Video Renderer "OpenGL" and OSD Renderer OpenGL2, in which case the preview window is not shown, with decoder Mac Acceleration or video renderer quartz-accel the LiveTV picture overlays the EPG and if you switch back to LiveTV that is not scaled correctly anymore. My Minis have a Intel GMA GPU, but at least one user confirmed this behaviour ​here. Both of us are running Snow Leopard, should we try our own compile as sniderpad still seems to be on Leopard.

Please advice whether this is related or should become it's own ticket or what additional information you need.

Hi ppl!

I looked into the quartz renderer and made it going. I'll attach a patch against release-0.23-fixes.

• EPG embed video shows up and scales proper
• going back, fullscreen is restored
• manual zoom works
• manual aspect needed some hacks in myth api ...

Still buggy:

• hit apple+q closes the video window but myth keeps running (how to tell myth to quit?)
• I haven't tested the other gimmiks like floating window or output to the dock. I hardly miss that features.

Also to make 0.23 going for MacOsX, look at ticket:8179 and ticket:8442

Please apply that patch!

fixes quartz video renderer on OsX

[Nigel]

chr, thanks for the patch. With it, bringing up the guide in Live TV does the right thing. Sadly, it creates another problem...
Aspect changing no longer works. Pressing W changes the aspect of the OSD, but the playback image is unchanged.
The patch does seem to contain a few things that are un-needed, but it did point me toward the API change in EmbedInWidget?() that I missed. I will commit a fix for that ASAP. Could you email me (nigel@… or on the developer's list) to discuss the other changes in your patch?

[Nigel]

(In [25133]) API change missed in a long-ago mythtv-vid merge [19417], which meant EmbedInWidget?() wasn't overriding the base class's version. On Mac OS X, should prevent unusable window after exiting Program Guide, but does not correct the window scaling problems. Thanks to 'chr'. Refs #6211

This cs(25133) breaks compilation for videoout_d3d.cpp as 'wid' is assigned to m_hEmbedWnd in the function. The #include "osdsurface.h" in videoout_d3d.cpp needs to go too If I don't set m_hEmbedWnd it seems to break HD playback? That could be something else tho

[Nigel]

(In [25138]) Fix my oops in [25134]. Thanks Mark. Refs #6211. The osdsurface and HD playback probs will have to wait until I can test build.

Well, guess what those uneeded things are fixing .... xD

I'll attach some patches, with some more comments, which are actually necessary to make myth0.23-fixes going on my mac-mini-ppc. I do believe, trunk needs that patches as well.

Press W and automatic aspect change of live tv works for me.

[Nigel]

(In [25263]) Allow video out subclasses to implement ToggleAspectOverride?(), and do that in Mac OS Quartz code. Apple-W will now do something! Windows code probably also should have this enabled? Thanks to Christoph Rudorff. Refs #6211.

[Nigel]

(In [25279]) Simple repair of embedded video in guide. Refs #6211. Does not obey aspect/fill in embedded area, or after exiting guide, but might enable PiP (untested)

(In [25291]) When pausing video output to access GUI (e.g. EPG from Recordings), hide that video rectangle so users can actually see the GUI and popups. Seems to only be a problem on Mac OS X. Refs #6211. Hopefully negates Christoph's part1.patch. (also contains some whitespace and comment changes)

(In [25292]) Also hide fullscreen output when video paused for GUI (e.g. EPG guide grid). Refs #6211. Now I just gotta backport all this to 23-fixes.

calling End() after my recent changes to enable embedding).
