Failed to export recording: Sending frame to channel failed #1515
Description
Description
Failed to export recording: Sending frame to channel failed
Reproduction
Additional Context
- Cap version:0.4.0、0.4.3
- Operating system, version:WIN11
- Device (optional):RTX3080 32GB RAM
Cap_0.3.83 still works normally, but playback during editing after screen recording is very laggy. However, with Cap 0.4.0 or 0.4.3, exporting often fails, and the editing mode is so laggy it's like watching a slideshow. It feels like a step backward in terms of optimization. The problem I'm facing now is that the videos I recorded with 0.4.0 cannot be exported, and rolling back to 0.3.83 doesn't allow me to open those screen recording files anymore. I'm so frustrated.And I couldn't find any logs.

Export now runs an encoder self-test with a libx264 fallback, added since this was reported. This specific failure is believed resolved, please re-test on the latest version and open a fresh issue with logs if export still fails this way.
