Built for legacy-media triage
More than a generic video player.
FLV-specific structure checks help explain playback and seeking problems while your original files remain untouched.
Queue whole collections
Open FLV files, run bounded scans of local folders, search the queue, and safely resume recent review work.
Understand file health
Review streams, metadata, timeline continuity, truncation signals, tag sizes, and a cancellable SHA-256 fingerprint.
Review precisely
Seek, change speed, request adjacent frames, set an A–B loop, and pin the player above other windows.
Control audio and subtitles
Choose available tracks or add a validated local SRT, ASS, SSA, or WebVTT subtitle up to 4 MB.
Leave a portable record
Add timestamped markers, save a review session, and export diagnostics as JSON or readable Markdown.
Keep work on your PC
No account, ads, telemetry, cloud processing, automatic uploads, or bundled codec-pack setup.
Clear scope. Honest results.
Inspect even when a stream cannot play.
Profile B plays FLV files containing FLV1 video and MP3 audio. H.264, AAC, F4V, and other combinations are outside the supported playback scope. When a stream is excluded or damaged, FLV Video Player Pro keeps its metadata, findings, markers, and export tools available instead of claiming a repair it did not perform.

Coming to Microsoft StoreQuestions, answered
Before you open the archive
Does the app upload my videos?
No. The desktop app initiates no uploads, analytics, advertising, cloud processing, or update-check requests.
Will every FLV file play?
No. Profile B supports FLV1 video with MP3 audio; other or damaged streams are outside the playback claim. Inspection may still remain available.
Does it change or repair files?
No. Source media is opened and verified for local review. Snapshots, sessions, and reports are written only when you choose a destination.
Where can I get help?
The support guide covers playback, subtitles, damaged files, diagnostics, and the information to include with a support request.
