Does not render non-AV tracks

Current Raven doesn't render non audio / video tracks. We need to add support for arbitrary track types to be able to fully inspect an OTIO timeline

Performance + power consumption issue

Raven naively uses Dear ImGui in a way that re-renders the window even when not needed. The application's performance & power consumption could be improved by fixing this oversight.

When I initially wrote Raven, this continuous rendering was problematic, and I attempted to use a branches of ImGui with support for ImGuiConfigFlags_EnablePowerSavingMode (see POWER_SAVING in the code). If I recall correctly Raven's WASM/Emscripten build suffered from this issue quite badly, and I was disappointed to see that the power saving mode didn't work in the browser environment due to specifics of how Emscripten works.

At the time, I set that aside for "later" figuring that Dear ImGui would improve and Raven's energy usage would improve by virtue of that change. As of this writing, that feature has not landed in ImGui.

Today (Feb 2024) I was curious to measure Raven's performance on macOS. A quick look at Raven in Activity Monitor shows that this is not a problem. The app consumes 0% CPU when it is not active, or when the user's cursor is not moving, and only about 10% when the user actively zooms/pans. I'm not entirely sure why or how that changed, so some investigation should be done. Also we should compare on other platforms (Windows, Linux) to see if those have also improved.

I also found that ocornut, Dear ImGui's author, has written this advice on the subject which looks pretty straight forward to implement, and which proposes a solution for the Emscripten scenario: https://github.com/ocornut/imgui/wiki/Implementing-Power-Save,-aka-Idling-outside-of-ImGui

So this issue is here to ask for help with the following:

Measure Raven's CPU usage when active vs inactive on these platforms:
- Windows
- Linux
- Emscripten
If those are problematic, then attempt to implement the strategy outlined in the linked wiki page above.

Inspector doesn't support `UnknownSchema` in metadata

At this time Raven doesn't display underlying key / values of UnknownSchema objects in an items metadata. The tree can't be expanded further than the schema root.

To implement this feature, we need a new C++ API to retrieve the data dictionary from the object. See AcademySoftwareFoundation/OpenTimelineIO#1234

Screenshot (redacted)

Crashes when reading OTIO file with SerializableCollection

If Raven is given an OTIO file with a top-level object that isn't a Timeline, it crashes. The most common case of this is an OTIO file with a SerializableCollection containing multiple timelines.

At the very least, it should give the user a helpful error message instead of crashing.

Even better it could present each different type of OTIO object in a reasonable manner. For SerializableCollection, maybe tabs for each item. For other types like MediaReference, Clip, etc. it could just show the JSON and Inspector without the timeline view.

Enable/disable clips

Background:

Clips (and other Items) have an enabled flag which toggles whether they are enabled or disabled. For audio clips, this is a mute/unmute toggle. For video clips, a hide/show toggle.

Problem:

Currently Raven's display shows no indication whether a clip is enabled or disabled.

Feature Request:

Raven should draw disabled Clips in a muted grey color so the enabled/disabled state is clear at a glance.
In the Inspector tab, Raven should show an "Enabled" checkbox which can be toggled on/off to modify the currently selected Clip (or other Item).

Stretch goal:

Tracks are also Items, and can be disabled. Raven should draw whole Tracks with a ghosted/grey style.

Estimated Difficulty:

Easy
Some familiarity with C/C++
Only 2 source files need to be modified (timeline.cpp and inspector.cpp)
Data structure is already in place.
Test data is available.
Only user interface needs to be changed.
No difficult design or architecture choices.
This task is a good introduction to Dear ImGui

HIDPI on mac

HIDPI in imgui is still a mess, if you have a monitors with different DPI's on mac, this happens when you move a window to the higher DPI display.

The easiest work around is to just disable retina framebuffers in glfw

glfwWindowHint(GLFW_COCOA_RETINA_FRAMEBUFFER, GL_FALSE);

I've gotten hidpi working somewhat smoothly on Windows in one of my branches. It's still a mess.
glfw enables DPI awareness by default on Windows. I wish glfw had an equivalent hint for windows.

Trying to install it on Fedora

Hello folks, I'm facing some issues when trying to install it on fedora. Let me share some info.

Initially, I got this

(otio-p37) [wpinheir@ironman build]$ cmake ..
-- Checking for module 'gtk+-3.0'
--   Package 'gtk+-3.0', required by 'virtual:world', not found
CMake Error at /usr/share/cmake/Modules/FindPkgConfig.cmake:607 (message):

  libs/CMakeLists.txt:6 (pkg_check_modules)


-- Configuring incomplete, errors occurred!
See also "/home/wpinheir/code/raven/build/CMakeFiles/CMakeOutput.log".

Then after some time, I returned and once I was very excited to see this working, I tried all the steps below, in order to see this working on linux.

Note. This was complaining about gtk package, but as you can see below, I have already.

the cmake passed a lot of dependencies issues and now, I'm stuck here.

Ps.: I was trying to add the path in some files, better than creating a lot of symlinks, but none of them worked.

Any help will be very welcome.

Audio waveforms

Most NLEs show audio waveform shapes in audio clips on the timeline. Raven would be greatly improved if it had this feature also.

Here's a mockup of what that could look like

Adding such a feature, however, opens many questions about media file formats, loading of media reference target_urls, and other specifics which might be problematic. By design Raven doesn't show video, or play video or audio, so showing waveforms invites the question if the tool should go in that direction or not, which is... complicated.

I figured I'd ask here first, thanks.

Clip color obscures important text details

Bug:
When a clip is selected, it is highlighted in white, which is the same color as some of the text on the clip, making the text unreadable. Furthermore, when adjusting a clip's color in the inspector, the clip color is not visible until you deselect the clip.

Suggested Fix:

The timecode text on each clip could flip from white to black depending on the clip's fill color (like the clip name text does already).
A better choice for the selection highlight color (perhaps a tint, brighten or darken) instead of pure white could work better.
Both of these problems would be avoided if the selection highlight was a border instead of coloring the entire clip.

Track & clip colors

It would be great to have the ability to color code clips and/or tracks in Raven.

For starters, colors could be set in OTIO metadata, but once that is working, we could explore adding that as an official schema feature in OTIO.

Improve WASM experience for loading an OTIO file

Note: I'm not a C++ developer, nor do I have a lot of experience with WASM! Maybe I'm misunderstanding parts of this.

Today I was able to successfully deploy a built WASM version of raven onto one of our web servers. Exciting!

Following the instructions in the README got me a running version of raven, but I spent quite a bit of time trying to figure out how to actually read a file, since the "Open" menu item doesn't do anything in the browser, and I couldn't figure out any way to use javascript to interact with the main window!

I followed a few guides on how to create "files" (in-memory) in emscripten, and these all caused raven to crash completely.

BUT!

What I finally ended up doing was replacing from_json_file(...) with from_json_string(...) in app.cpp. This allowed me to pass in raw json as an argument to the emscripten app, and get the timeline loaded in the browser!

Anyway, after all of that I had two thoughts:

I don't know how emscripten works, but can we expose a function like from_json_string() to javascript? This way people can write their own javascript code to handle finding and reading OTIO files.
Could we add an argument into the main CLI app to do handle passing in raw json, instead of a file path?
Documenting the WASM stuff better would be lovely, especially for people like me who have no idea what they're doing!
