We are trying to send a test video stream directly from Aximmetry via RTMP. However, we are encountering repeated errors in the log:
- "Failed to create file: I/O error
- "Failed to stream video to rtmps://…:443/app/…"
- "Error writing audio frame: I/O error"
- "Error closing file: I/O error"
We are using an RTMPS endpoint (AWS IVS-style URL). The same RTMP/RTMPS URL and stream key work without any issues on the same machine when using Wirecast, so we can likely rule out network, firewall, or credential problems.
Hi,
This may still be caused by the firewall if Windows is blocking Aximmetry while allowing Wirecast to work normally.
As a first step, try running Aximmetry as Administrator: https://my.aximmetry.com/post/3761-rtmp-output-error
If that does not help, test whether Windows Firewall is the source of the problem by temporarily disabling it, or check that Aximmetry is properly allowed through the firewall.
In addition, make sure the stream is started correctly in Aximmetry. More details are available here: https://aximmetry.com/learn/virtual-production-workflow/setting-up-inputs-outputs-for-virtual-production/video/streaming/streaming-youtube-facebook-twitch-etc/#starting-your-stream
If none of the above resolves the issue, please tell us which exact AWS services you are using. We will do our best to recreate the problem using the same setup and settings.
Warmest regards,
