FLV Streamer FAQ

How do I play an older FLV file online?

Upload your FLV file. Most browsers cannot decode FLV; when yours cannot, the page says so and links to a converter, and converting to MP4 makes it play.

Why won't my FLV file play in the browser?

FLV often wraps legacy codecs (DivX, Xvid, WMV3, etc.) that modern browsers don't decode natively. Converting the FLV to MP4 (H.264) makes it play everywhere.

Will I lose quality playing or converting FLV?

Playback never changes your file. If you convert FLV to a modern format, choose a high-quality preset to keep the result visually close to the FLV source.

Is FLV still a good format to keep my videos in?

FLV is widely compatible with old software but uses dated, less efficient compression. For streaming and small files, converting FLV to MP4 or WebM is usually better.

Does the FLV player upload my file?

No. Your FLV file stays in your browser for local playback and is never sent to a server.

Can I play FLV on my phone?

Mobile browsers have limited FLV codec support. If it won't play, convert the FLV to MP4 first for reliable mobile playback.

Can I add subtitles to a FLV video?

No. The player has no option to load SRT or VTT subtitle files.

Why is my FLV file so large for its quality?

Older FLV codecs compress less efficiently than modern ones. Converting FLV to H.264/H.265 typically shrinks the file substantially at the same quality.
