M3U8 Player

Paste an HLS (.m3u8) link and press Play stream. The player shows every quality level with its resolution, bitrate and codecs, tells you whether the stream is live or on demand, and explains in plain words why a stream will not load.

How to use the M3U8 Player

1. Paste the .m3u8 address into the Stream URL box, or press one of the test streams.
2. Press Play stream. The playlist is read and the video starts; the Stream info panel lists every quality level.
3. Pick a quality from the menu to lock a resolution, or leave it on Auto to adapt to your connection.
4. Watch the live stats under the player to check buffering, bitrate and dropped frames.
5. If it fails, read the explanation box: it tells you whether the cause is CORS, an expired link, a wrong address or an unsupported codec.
6. Have a playlist file? Open the Paste or open playlist tab to check its contents, or select it together with its segment files to play it offline.

How HLS streaming works

HTTP Live Streaming cuts a video into short files, usually 2 to 10 seconds long, and describes them in plain-text M3U8 playlists. A master playlist points to several renditions of the same video at different resolutions and bitrates. The player measures how fast segments download and switches up or down between renditions, which is called adaptive bitrate streaming. Because everything is ordinary HTTP files, HLS works through any web server or CDN.

A minimal master playlist looks like this:

#EXTM3U
#EXT-X-STREAM-INF:BANDWIDTH=3000000,RESOLUTION=1280x720,CODECS="avc1.64001f,mp4a.40.2"
720p/index.m3u8
#EXT-X-STREAM-INF:BANDWIDTH=800000,RESOLUTION=640x360,CODECS="avc1.42c01e,mp4a.40.2"
360p/index.m3u8

Common M3U8 tags

Typical bitrate ladder

Streaming services choose their own ladders, but these values for H.264 at 30 fps are a common starting point. Higher frame rates and more detailed content need more; HEVC and AV1 need roughly 30 to 50 percent less for similar quality.

Data per hour = bitrate in Mbps × 3,600 ÷ 8 ÷ 1,000 GB. For smooth playback your connection should be at least 1.5 times the bitrate of the level you want.

Troubleshooting checklist

• CORS error: the server must answer with Access-Control-Allow-Origin. Test it with a CORS tester, or play the stream in VLC.
• 403 Forbidden: signed links expire, often after minutes or hours. Copy a fresh link from the original site.
• Plays without picture: the video codec (often HEVC) is not supported by this browser; the audio may still play.
• Stalls every few seconds: check the buffer and your bandwidth in the stats. Pick a lower quality if your bandwidth is close to the level bitrate.
• http:// link fails: secure pages cannot load insecure streams. Try https:// instead.
