You can easily identify an indexing issue by observing how the file behaves in standard media players like VLC, MPC-HC, or PotPlayer. Look for the following symptoms:
Open your terminal or command prompt and run the following command: ffmpeg -i input_broken.mkv -c copy output_fixed.mkv Use code with caution. -i input_broken.mkv : Points to your corrupted source file.
The scrub bar (timeline) is grayed out, making it impossible to click and skip around.
If an MKV file lacks a Cues element (common with incomplete downloads or interrupted live recordings), the media player must estimate the location or read the entire file sequentially to find the requested timestamp. This results in heavy CPU usage, sluggish seeking, or software crashes. Common Causes of Broken or Missing MKV Indexes mkv index
