enhancement: embed playback box, move end of recording prompts to the OSD.

[skamithi]

I posted a huge diff couple weeks back on the dev alias and got some good feedback on it.

This is the first part I wish to submit. I hope it to be a replacement for the "Jump to Recorded Programs" OSD option.

Embedding the playback box involves 4 steps

1) Consolidate the tv object creation code. Created a startTV function that other parts of mythtv can call to start watching a live tv stream or a recording. I've made sure that playlists still works.

2) Add the code in playbackbox.h/cpp , and tv_play.cpp to allow embedding of the playbackbox widget, and cleanup/remove unused functions/variables.

3) Move the playbackbox.h and playbackbox.cpp to libmythtv directory.

4) Ask theme developers to create a new window called "playback-video". This container is essentially playback container with an object called "tv_video", where the recording will be shown. If a theme doesn't have a playback-video container, recording is paused, the "playback" container is used.

1st step is done. I've made 3 changes to mythtv functionality:

i) End of the recording prompt has been moved to the OSD space. Doing this also allows you to rewind, in case you've forwarded too far, and reached the end of the recording.

ii) (and i can change this back to the current mapping). Added a "STOPSHOW" action. On my remote, i have an "exit" and a "stop" button. When i hit stop, I want it to prompt me. When I hit "exit" i want it to quit the show, with no prompt. the "stopshow" action maps to the "stop" button. This way, when I hit the "off" key on my harmony remote, it exits, the show. Before, it would just show the prompt, and never quit.

If this change is accepted, then in the dialog displayed, a dev can add "delete recording" option at a later stage. Selecting "Delete recording" should bring up another dialog asking if you are sure , just like the end of recording prompt. This will allow a user to delete a show midstream if necessary. Right now the OSD dialog only accepts 4 buttons. Looks like a theme change needs to be made to accomodate 5 buttons in the dialog.

iii) When prompted to exit the video, the prompt will remain up for only 2 minutes, then stop displaying, and either exit the show, if at the end, or continuing to play the show.

I haven't changed the tv object creation code in manualbox.cpp. I don't really know what the manualbox is for, so decided not to touch it.

Thoughts, comments are always welcome. my IRC name is skamithi.

[skamithi]

if step one is not rejected, i will continue with step 2 once step 1 is committed.

[skamithi]

still doing further testing. going to test how jumppoint activation affects the code, and looking at other tests before commiting.

[skamithi]

changed "stopshow" action to just "stop". gnome42 offered to help test before i commit.

[skamithi]

changed "stop" action back to "stopshow" from feedback from gnome42.

(In [11519]) Refs #2426. Step 1 patch for the ability to access the "watch recording" screen while watching a show. major code change is the consolidation of most of the startTV calls in various places to one function TV::StartTV. feature change: end of recording prompt is moved to the OSD. this means that at the end of the recording a user can hit any of the rew buttons to jump back, if this was a mistake. ESCAPE action no longer brings up the prompt if prompting is enabled. this function is now done by the "STOPSHOW" action. So now the EXIT button just exits, and the STOP button can either prompt you or behave like the EXIT button depending on the exit prompt setting. thx to gnome42 for testing this patch. pls read the ticket for more details.

[skamithi]

(In [11523]) Refs #2426. per isaac suggestion. changed keybinding. new keybinding is called EXITSHOWNOPROMPTS. this just quits, even if prompts are enabled. removed STOPSHOW action. ESCAPE action will now bring up exit prompts if prompts is enabled. if u chose delete recording from the exit prompt and chose "keep it", recording doesn't exit. resolved that.

[bjm]

(In [11528]) Per comments by Chris Pinkham and Greg Estabrooks, the OSD delete options should not be destructive by default. The default choice is now "No, do not delete". Refs #2426.

[skamithi]

(In [11530]) Refs #2426. if user executes the DELETE action it will show the delete prompt regardless of what the exit prompt setting is. also, just exit the video exit prompt if in a dvd menu.

[skamithi]

(In [11531]) Refs #2426. typo in [11530]

[skamithi]

first version of the part 2 patch. Basically it just replaces the Jump to Program stuff. So to activate it, do as if you were going to "Jump To Program". Instead of a OSD screen, you should now see the Watch Recording screen. I have set the behaviour to be consistent with the other embedded widgets e.g schedule recording, program guide, etc. The video is paused and the watch recording window is displayed. The active show is unhighlighted. buttons such as "play and delete" are removed. Creating a playlist in this mode is not allowed, and those commands don't exist. Preview Video is disabled ( it caused too many lock/unlock problems).

[skamithi]

to test part 2, you have to create symlinks to playbackbox.h and playbackbox.cpp in libmythtv directory. when all is done, these files will be moved to the libmythtv directory.

mythtv>cd libs/libmythtv
mythtv>ln -s ../../programs/mythfrontend/playbackbox.cpp
mythtv>ln -s ../../programs/mythfrontend/playbackbox.h

[skamithi]

(In [11570]) Refs #2426. remove double delete confirmation. put delete OSD in the same order as the watch recording delete prompt. Set default for delete osd to "do not delete"

[Mark.Buechler@…]

Found two faults, one where the frontend segfaults, the other where it locks. Both are triggered by entering recordings from "Jump to Program" from an already running recording. I managed to successfully jump from recording to recording a few times, however.

[skamithi]

remove pbinfolock around runplaybackbox call in tv_play.cpp .

[skamithi]

(In [11581]) Refs #2426. prevent end of recording prompt from appearing during recording editing. save the bookmark when EXITSHOWNOPROMPTS is executed.

[skamithi]

going to use a jumppoint or something similiar to activate embedded pbb. isaac does not want playbackbox.h/cpp moved.

[jochen]

In Ticket #1772 there is a patch for a old version wich allows writing to more than one file from the dvb recorder. This is a part of the multiple channels from one transponder fix.

When someone try's to fix this, this may be a start...

[skamithi]

use function pointer to pass runplaybackbox to tv_play.cpp functions. Jump to programs only works when running mythfrontend. using mythtv exec jump to programs is disabled.

[skamithi]

temp workaround till pin support is added for the JUMPPREV/(jump to last watched show) option. if the recording groups of the current program and next program are not the same, clear the lastProgram variable.

[John Poet <jppoet@…>]

When watching a show where the "end" of the show is never reached due to a cutlist, the "end of recording" prompt is never displayed. Minor issue, since you can delete the show once back in the "Watch Recordings" list.

John

[skamithi]

end of prompt not shown if a cutlist causes the end of the recording to occur before the "real" end of recording. fixed issue where jumping ahead doesn't respect cutlists. this patch should resolve both issues. 1st issue depends on the 2nd.

[skamithi]

(In [11637]) Refs #2426. step 2. when jump to program is executed , this will now bring up the watch recording window instead. currently playing show, comes up as an inactive program. if theme developers would like, this can be changed and a color can be assigned to it. perhaps in the playback window theme, create a "currentlyplaying_fnt" font name and the code can check for this? step 3 is to enable this feature while watching live tv. see ticket for more details.

[skamithi]

(In [11638]) Refs #2426. hittin "left" when arrowaccel is enabled may not work as intended on an exit prompt, if its mapped to any rewind function. this ensures that the left action is honored.

[skamithi]

2 things i'll do for step 3. add pin support for the program accessed using JUMPPREV action. So if the program that was last watched is in a recording group that is password protected, mythtv should pause the video, and bring up a password prompt . Then I will also allow the watch recording screen to be accessed while watching live tv.

[skamithi]

(In [11667]) Closes #2645. Refs #2426. resolves vague responses on new end of recording dialog box.

[skamithi]

(In [11678]) Refs #2426. end of prompt not shown if a cutlist causes the end of the recording to occur before the "real" end of recording. fixed issue where jumping ahead doesn't respect cutlists. this patch should resolve both issues. 1st issue depends on the 2nd.

[skamithi]

step 3. added watch recording feature for live tv. gunzip file contains change to the Titivillus theme. created a "playback-video" window in the ui.xml. This theme change allows you to continue to watch live tv while looking through the list of recordings. If playback-video theme change is not available, it pauses live tv and shows the "watch recording" window using the "playback" window in ui.xml. other themes can be changed as well.

[skamithi]

(In [11705]) Refs #2426. step 3 patch. add jump to program feature when watching live tv. also added recorded group pin support when accessing the last watched program (JUMPPREV). the pin prompt window is not aligned properly. couldn't figure out how to do it. if could fix the window alignment, that would be very nice. To access the watch recording window without pausing live tv you need a "playback-video" container in your theme. provided one for the one i use (titivillus).

[skamithi]

step4: cleanup..remove end of recording code from playbackbox.cpp and fix any bugs reported in the next 2-3 weeks.

[skamithi]

prevents state change from occurring while pause action is been executed. prevents a crash when changing to a different recording.

[skamithi]

(In [11714]) Refs #2426. crash while switching between recordings. prevent state change from occurring while pause is executed. also prevent the pause osd from showing in this case.

[skamithi]

(In [11797]) Refs #2426. some cleanup.

[skamithi]

allow the use of the playback-video container on a prerecorded or recording show.

[skamithi]

(In [12217]) Refs #2426. if a recorded show ringbuffer cannot be started , while loop in TV::StartTV() never quits. this should force it quit. easily reproduced by hitting "play dvd" when there is no dvd.

[skamithi]

change the IsNearEnd?? detection code in tv_play.cpp. makes it easier for the next enhancement, i'll introduce in a later ticket which is to keep the prerecorded running during the program guide.

[skamithi]

(In [12594]) Refs #2426. if embedding the playbackbox, change the behaviour to pause the video when you've reached the end of the recording and maintain the embedded window. previous behaviour was to quit embedding when you reach the end of the recording. this way I'm able to finish doing what I was selecting/changing in the playbackbox without it quitting on me.
