Troubleshooting FLV/MKV Playback Issues
FLV and MKV files sometimes do not play the way they should. The cause can be missing codecs, outdated players, or even file errors. Here are simple troubleshooting steps you can try!
Troubleshooting 1: Video Does Not Play
If your video does not open, it may be a codec issue. Install a reliable player like VLC Media Player, which supports both FLV and MKV without needing extra codecs.
Troubleshooting 2: No Sound
When the picture plays but no audio is heard, the audio codec may not be supported. Updating your player or installing a codec pack like K-Lite Codec Pack often fixes this.
Troubleshooting 3: Lag or Stutter
If the video stutters, your device may not handle high resolution well. Try lowering the resolution or bitrate, or convert the file to a lighter format for smoother playback.

If the video file is damaged, it may freeze or not play at all. In this case, try re-downloading the file or using a repair tool like Stellar Repair for Video.
