Hello. I've been working on porting one of my previous projects to XBMC (Video here: https://www.youtube.com/watch?v=XtlR-wWlbDQ) that combined a Perl script, an Arduino, and VLC Media Player. Its function: given parameters for desired revolutions, video playback could be modulated to keep the person (me) at a reasonable pace on an exercise bike.
I am porting this setup to XBMC because I'm replacing my previous home theater setup with Raspbmc. I've... honestly been having a lot of fun with it, and thanks to probably a lot of people for making it straightforward to slap something together.
But the questions...
Question #1:
So far, I have a working port that can pause/play the queued media provided I keep up. However, I'm finding that the functionality I had in VLC for programmatically speeding up or slowing down the video appears to be missing from the Python Addon API (the latter being the more important function).
The xbmc.executebuiltin( 'PlayerControl( Forward )' ) type of controls seem to only support doing "fast forward" or "rewind" types of playback. In my previous implementation, I was able to slow down the video if I dipped below 100%, and could walk playback speed up or down depending on how I did. Looking at the documentation for the OMXPlayer, hitting "1" and "2" will slow down or speed up video, respectively. Are these commands available from within the Python API?
Question #2:
I previously had a heads-up text display that I could use to indicate things like a) Current RPMs, b) Desired RPMs, c) remaining time in a video, etc. I'm finding that there is a Notification built-in function, but I cannot for the life of me figure out what it is doing (if anything at all).
Really, I only want a bit of text on the screen that will update no more than once a second, showing me my exercise progress. Is there a way to accomplish this via the Python API? Any of the APIs?
Thanks in advance.
