AMC SDK detects a file as being played but the video is frozen

[simonebarattin]

Good morning,

I'm having an issue with the AMC SDK. I'm developing a streaming application in C#, which shows the live stream of 5 different cameras and allows then the user to record and playback the videos.

What happens is, sometimes when I try to playback the videos, 4 out of 5 play normally but one is like frozen to the first frame. Then, If I stop the videos then the frozen one goes to the correct frame.

I checked the status during the reproduction of the videos and even for the frozen one it shows status 3 (initialized + playing). Also the "OnNewImage" event is triggered even if the video is frozen. So it seems the AMC pipeline is "providing" the frames but the video view doesn't get updated. I tried to invalidate the control to make it refresh but without result. I checked also if some error is reported in the OnError event but nothing is in there.

I think then the problem could be related to the video decoder?

Some info on the setup:

• Axis Media Control SDK 7.5.2 (last version available)
• H265 Decoder provided in https://github.com/orgs/AxisCommunications/discussions/818
• the cameras used are 5 AXIS F2135-RE Fisheye Sensor connected to 2 AXIS F9114 Main Unit. The version of the firmware is 12.2.52. The files I play are the ones I obtain untouched from the recording (.asf videos)

This is the process dump of the diagnostic tool provided in the above mentioned discussion: https://drive.google.com/file/d/1XZEs0ieqQkYMZH1s-F5HB7CKetOqW_P2/view?usp=sharing

Thank you for your support. Regards,
Simone
