windows access violation loading cairo ToyFontFace

[dyk74]

Hello, I have some trouble creating video file on win11... here the command (I removed personal information) and the result:

python .\venv\Scripts\gopro-dashboard.py --font trebuc.ttf --layout-xml C:\Users[...]\layout.xml --use-gpx-only --gpx C:\Users[...]\20230706030824-58228-data.gpx --profile overlay --show-ffmpeg --debug-metadata --print-timings --overlay-size 1920x1080 C:\Users[...]\test.mov

Here the result: Starting gopro-dashboard version 0.124.0 Running ['ffmpeg', '-version'] Running ['ffmpeg', '-v', 'quiet', '-codecs'] Running ['ffmpeg', '-version'] ffmpeg version is 6.1.1-essentials_build-www.gyan.dev Using Python version 3.12.1 (tags/v3.12.1:2305ca5, Dec 7 2023, 22:03:25) [MSC v.1937 64 bit (AMD64)] GPX/FIT file: 2023-07-02T11:41:40+00:00 -> 2023-07-02T11:53:02+00:00 Timer(loading timeseries - Called: 1, Total: 8.28410, Avg: 8.28410, Rate: 0.12) Generating overlay at Dimension(x=1920, y=1080) Timeseries has 6821 data points Processing....

Where is my mistake (I suppose I made some) Thank you

Hi. Thanks for your interest in the software!

The output you have posted looks like it might not be complete. Please could you double-check that there isn't any missing.

I dont have a Windows machine, so testing on Windows is a bit tricky, but it is believed to work on Windows, and it gets tested when there are significant changes.

I'll find a Windows machine and see if there is a problem. In the meantime, I'd appreciate it if you could double-check that you posted all the output.

Thanks!

[dyk74]

I've checked the output and it is complete...that's why I opened the issue

[dyk74]

Could I send you my layout file? maybe is the file wrong...

[time4tea]

Yes, please do! In theory, the program should report an error parsing the file, but maybe not in this case. Good idea. Please could you send it to gopro-overlay@time4tea.net

Thanks!

Hi

I had the chance to look at your file. When I run the program I am getting an error - I am surprised that you don't see anything? It would be interesting to know how you are running the program.

Anyhow - this isn't a very good error message, but it is caused by the following bit in your layout file:

<component type="text" y="80" size="0" rgb="255,255,255,128">Alt(m)</component>

The font size has been set to zero which is causing a problem. If you set this to a larger value it should work. In the meantime I can add some validation for this value so that the error message is improved.

Thanks for bringing it to my attention.

Hello, I've followed your instruction on the website. Set-ExecutionPolicy Unrestricted -Scope Process

.\venv\Scripts\activate.ps1

python .\venv\Scripts\gopro-dashboard.py --font trebuc.ttf --ffmpeg C:\Users\james\Downloads\ffmpeg-6.0-essentials_build\ffmpeg-6.0-essentials_build\bin input.mp4 output.mp4

Of course the last line has been changed with the line I've sent you before. And I did receive back any error. I will check and I'll give you a feedback.

Error message should be improved in V0.125.0 which is on PyPI.

[time4tea]

I have just tried this on a windows machine - and i agree - you cannot see the output! Even the improved error message. I don't understand this behaviour.

[time4tea]

OK - This is actually a very different error to what it first appeared.... the program is crashing inside PyCairo.

Windows fatal exception: access violation

This seems to be that the required font isn't installed, but I wouldn't expect a fatal error. Still investigating...

[time4tea]

This seems to be a problem in pycairo. Using non-cairo libraries will work, or docker images.

Hi again, I saw your demo in pycairo and I made some test and (I don't know why) this demo works in Windows 11..Maybe the demo can help you: import faulthandler import cairo import os

faulthandler.enable()

print([x for x in os.listdir('c:/windows/fonts') if "arial" in x]) with cairo.SVGSurface("example.svg", 200, 200) as surface: context = cairo.Context(surface) x, y, x1, y1 = 0.1, 0.5, 0.4, 0.9 x2, y2, x3, y3 = 0.6, 0.1, 0.9, 0.5 context.scale(200, 200) context.set_line_width(0.04) context.move_to(x, y) context.curve_to(x1, y1, x2, y2, x3, y3) context.stroke() context.set_source_rgba(1, 0.2, 0.2, 0.6) context.set_line_width(0.02) context.move_to(x, y) context.line_to(x1, y1) context.move_to(x2, y2) context.line_to(x3, y3) context.stroke()

face = cairo.ToyFontFace("arial.ttf", cairo.FONT_SLANT_NORMAL,  cairo.FONT_WEIGHT_NORMAL)
print(face)

In my point of view when the class is called somehow the surface is missing: I suppose that the "face" doesn't know where should be added

[time4tea]

Hmm. that is interesting. thanks!

[dyk74]

I found a workaround (not clean but sounds working): I commented this major_annotation = EllipticAnnotation( ellipse=circle_with_radius(text_radius, centre), tick=TickParameters(step * 2.0, 1, 0), colour=major_annotation_colour, # face=ToyFontFace("arial"), mode=AnnotationMode.MovedInside, texts=major_texts, height=0.05, stretch=stretch, start=start + (length / sectors), length=length - (length / sectors) )

and on every file where the "face" is called...sounds working (on win11) ...please check it deeply
