| Problem | Likely Cause | Solution | |---------|--------------|----------| | MKV upload fails | File size exceeds PHP/Apache limit | Increase upload_max_filesize and post_max_size in php.ini, or use FTP/SFTP | | Video plays without audio | Missing audio codec (DTS, FLAC) | Transcode audio to AAC using ffmpeg: -c:a aac -b:a 256k | | Subtitles don’t appear | Browser doesn’t support MKV soft subs | Extract subtitles: ffmpeg -i movie.mkv subs.srt and load externally | | Buffering every few seconds | Network bottleneck or disk I/O | Enable chunked streaming via HLS or MPEG-DASH | | “File not found” after upload | Permissions issue | chown www-data:www-data movie.mkv and chmod 644 |

Uploading is only half the battle. The real need behind is playback. Browsers do not natively support MKV containers. Here are three solutions.
MKV (Matroska Video) is a popular multimedia container format. It isn't a video format itself but a "wrapper" that can hold an unlimited number of video, audio, and subtitle tracks in one file.
When you expose to the internet, you risk hotlinking, bandwidth theft, and unauthorized access.
