Sorry about the crash. I think it's likely related to the thumbnails that are created for each key frame, both in the bottom area and the side area. Not sure what the best solution is to address this.

It appears the issue with FLIR cameras is that when you have two of them of the same model connected at the same time, the identifier we use doesn't differentiate between them and this causes a crash. Single camera should work.

Is there a possibility that this will be enhanced/fixed in the future to allow for 2 of the same FLIR cameras to work? Or is this just a permanent shortcoming of the driver(s)?

Yes it should be fixable.

No, RTSP is not supported at this time.
See if the camera has an MJPEG stream, this is the protocol that is supported.

Thanks.

I know about this crash unfortunately at the moment I don't have a solution. I'm tracking the bug here: https://github.com/Kinovea/Kinovea/issues/165

It's an incompatibility between two external dependencies… unfortunately it's not looking good so far.

Hi, unfortunately I think you are hitting the bug where file names with Korean characters fail to load. There is no fix at this moment, a work around is to rename the files to use Latin characters, sorry.

Saving dual video with auto pause on key images isn't supported at this point. Same for slideshow feature, only supported when saving individual videos.

Yes it's a good observation. There is no "absolute" time reference so whether you assume the events in the images are happening at the beginning, middle or end of the frame interval doesn't really matter as long as you always assume the same alignment, addition/subtraction between time stamps will work the same. The timestamps are coming from the video file and ultimately from the camera where they could mean any alignment. Inside the playback screen as soon as the time interval starts it tries to display the corresponding frame.

To further complicate the issue many cameras have a rolling shutter, different *lines* are captured at different times within the frame interval.

At the moment there is not any way to do this but I've been considering this for a long time.
For my curiosity where is the json file coming from?

That's very odd and the first time I hear about something like this, I'm not sure what could cause the issue.

If you go to the log folder there might be a number of crash files with names starting with "Unhandled Crash", could you please send me the log.txt and log.txt.1 and any of those Unhandled crash files at joan at kinovea dot org please?

Are you working with two instances of Kinovea or dual screen inside one instance?
Do you have the same issue when working with just one video? Is it specific to when you work with two videos?

Normally when it crashes the next time you open it should propose to load the last session, including any unsaved changes, if you don't see that there might be a second problem.

So it picks up voice correctly but not the ball impact, at roughly the same volume? I'm not sure but maybe there is some sort of clipping of high frequencies or maybe it's even a feature of the microphone to remove high pitched "clicks" which are normally undesirable in voice communication? See if there is any sort of "helpful" noise filtering that you could disable.

Hi, these instructions are for an older version, there is an additional "arming" mechanism now that's preventing unwanted recordings, and it's disarmed by default (this may change in the future but for now it's like this). In the toolbar at the bottom of the screen there is a speaker icon that you need to toggle. Once you toggle it to "armed" it should work. You need to do this once at the beginning of the session.

You can start with this:
- Stream format = "Mono" or "Mono8"
- Exposition = 4405 µs or lower. (1000000 / 227)

Also for Daheng apparently sometimes the camera has a default bit depth at 10 bits which limits the max frame rate, for this you need to go in the Galaxy Viewer and change the setting for "SensorBitDepth" to "Bpp8".

I didn't quite get the relation between triple playback and HD framing.

It should be possible to add spacing between the two videos, or maybe a margin at the bottom, I'll write it down for later.

The plugins tend to be specific in the version of Kinovea they work with, for now. If you are using version 2024.1 I would suggest to use the GenICam plugin: https://www.kinovea.org/en/forum/viewtopic.php?id=2005

It is unlikely to happen in the near future. Other things you can do is launch two instances of Kinovea, but you won't have synchronization, or maybe synchronize two videos first, export that and then load the combo with the third.

May I ask if this is for synchronizing 3 different persons or 3 different views of the same person, or something else?
