:D

with snapshot:

$ dvrescue device://84:3c0a102a:00000000 --control "/dev/tty.RS422 Deck Control" -x test.dvrescue.xml -m test.mkv --csv --verbosity 9
Capture frame 1, press ctrl+c to stop.Segmentation fault: 11

at time of crash the xml is empty and mkv is 946176 bytes. test.mkv.zip

On my M1 laptop:

$ dvrescue device://84:160a010c:00000000 --control "/dev/tty.RS422 Deck Control" --capture -x test81.xml -m test81.mkv
2024-02-27 11:55:01.009 dvrescue[3808:38443] WARNING: AVCaptureDeviceTypeExternal is deprecated for Continuity Cameras. Please use AVCaptureDeviceTypeContinuityCamera and add NSCameraUseContinuityCameraDeviceType to your Info.plist.
Capture frame 1, press c
trl+c to stop.Segmentation fault: 11

xml is empty and the mkv is attached test81.mkv.zip

I tested the deck via /opt/homebrew/opt/ffmpegdecklink/bin/ffmpeg-dl -f decklink -i "UltraStudio HD Mini" -c copy -t 1 out.mkv and that worked fine.

Ok, retesting.

$ dvrescue device://84:160a010c:00000000 --control "/dev/tty.RS422 Deck Control" --capture -x test85.xml -m test85.mkv
2024-02-27 15:01:17.564 dvrescue[18700:168048] WARNING: AVCaptureDeviceTypeExternal is deprecated for Continuity Cameras. Please use AVCaptureDeviceTypeContinuityCamera and add NSCameraUseContinuityCameraDeviceType to your Info.plist.
Capture frame 14, press ctrl+c to stop.drice:dvrescue drice$ 

basically stops on its own right away and gives 3 files test85.zip

I get a little xml though

I then reran things when the deck was already playing and that time the capture kept running.

$ dvrescue device://84:160a010c:00000000 --control "/dev/tty.RS422 Deck Control" --capture -x test86.xml -m test86.mkv

3 files out again test86.zip

ah, some xml errors:

the <source> tag opens but never closes

<source video="sdi" audio="embedded" timecode="vitc">

If I change that element to <source video="sdi" audio="embedded" timecode="vitc"/> then it's valid xml but not valid to schema:

$ xmllint --noout --schema tools/dvrescue.xsd test86.xml
test86.xml:10: element source: Schemas validity error : Element '{https://mediaarea.net/dvrescue}source': This element is not expected. Expected is ( {https://mediaarea.net/dvrescue}frames ).
test86.xml fails to validate

@g-maxime can you also add the pts attribute?
