Problem Description
When compressing a video, the process fails with a "Muxer error". The log shows that the HEVC encoder produces no output sample within 10 seconds. I have tried switching the codec to H.264 (AVC), but the error still occurs. The target frame rate was originally set to 0, but I later changed it to 50 (same as original) – still no success. This happens on a MediaTek Dimensity 9400 device running Android 16.
Expected Behavior
The compression should complete successfully, producing a 720p video with the original frame rate (50 fps), without crashing or throwing a muxer timeout error.
