Huh, this is quite an amount of replies. The script basically works by inserting information about the current beat as well as the timing into the score, which is then output to svg. We then parse these svg files to retrieve this information and remove the codes. These cleaned svgs are then converted to png files. These are then turned into frames and sent to ffmpeg. Converting the svg is done using inkscape for now, as this one handles ligatures and such stuff. Of course this means that we lack otf features for now.
Currently this thing supports multiple pages as well as automatic scrolling (both vertically and horizontally). Support for repeats, jumps and omissions will eventually come, as well as handling of multiple scores (which I’ll implement by using score IDs. Alignment is done by setting the context property Score.timestep to the time in seconds. For jumps and repeats this will probably at some point allow giving a list of timestamps, one entry for each time the part is played. @Paolo: I started this because I just couldn’t get ly2video to handle timing well (that one uses a relative approach, so timing is adjusted by bpm. This is of course extremely volatile, as errors can sum up. My script instead aligns by the actual timestamp.). Also ly2video has to compromise on quality and speed as it works mainly on png. And yes, I’m going to publish the script once I’ve got it in a better shape. So far I’ve only been working on it a few hours. @Kira: Glad you like it! @Kevin: Syncing up to MIDI is surely possible. My script is fast enough to make display in realtime viable (and if we can modify the viewer of frescobaldi to draw additional stuff we can get even faster. So it should very well be possible to do something like this for Frescobaldi. @Hendur: This script is written in python so far. Currently it relies on the output of Lilypond, eventually it should do stuff like running Lilypond and injecting relevant Lilypond code automatically. @Mario: Yes! I will not give a more detailed explanation than the above for I’m a bit too tired now. I’ve currently just spend a few hours on this thing, once it is in a better shape I will make this available. @Tom: No, I’m not asking for feedback at this point. I’m just letting you know that I have something like this in the works. Once I have this far enough to be usable I’ll be open for feedback. @Kenneth: I don’t think you need to wait long, but I need to add some logistics first. Cheers, Valentin Am Freitag, 18.
