TSからFLVへの変換について
MPEG Transport Stream is the standard container for digital broadcasting, while Flash Video (FLV) was once the dominant format for streaming video on the web. Converting TS to FLV repackages broadcast content into the Adobe Flash container with H.264 video and AAC or MP3 audio: a format still used by some legacy streaming servers, RTMP-based workflows, and older content management systems.
TSをFLVに変換する理由
While Flash Player itself is discontinued, FLV containers remain relevant in live streaming infrastructure. RTMP ingest servers (used by OBS, Wirecast, and many CDNs including legacy Wowza/Red5 setups) accept FLV streams natively. If you are feeding broadcast content into an RTMP-based streaming workflow or archiving for a legacy CMS, FLV is the required format.
主な活用例
- Feeding recorded broadcast content into an RTMP-based live streaming server
- Uploading TV recordings to legacy content management systems that only accept FLV
- Converting IPTV captures for use with OBS Studio's media source (FLV input)
- Providing broadcast clips to legacy video platforms that still process FLV internally
- Archiving broadcast recordings for FLV-based video-on-demand systems still in operation
仕組み
The converter removes TS broadcast headers (PAT, PMT, null packets) and re-encodes the video as H.264 Baseline or Main Profile wrapped in FLV's tag-based container format. Audio is encoded as AAC-LC or MP3 at 128 kbps. FLV uses a simple tag structure (video tag type 9, audio tag type 8, script data type 18) with timestamps in milliseconds. An onMetaData script tag is injected for duration, bitrate, and resolution info to enable proper seeking.
品質とパフォーマンス
FLV with H.264 video delivers identical quality to the same codec in MP4 at the same bitrate. The container itself does not affect quality — only the encoding settings matter. At 4-8 Mbps for 1080p content, the output is visually excellent.

最良の結果を得るためのヒント
- 1Use H.264 Baseline Profile if the FLV will be used with older RTMP server software for maximum compatibility
- 2Set keyframe interval to 2 seconds for smooth seeking in streaming workflows
- 3Choose AAC-LC audio over MP3 for better quality at the same bitrate within FLV
- 4If the FLV is for RTMP streaming, match the encoding settings to your CDN's recommended ingest profile
- 5Consider MP4 instead of FLV for any non-RTMP use case — it offers identical quality with better modern support

TS to FLV conversion serves the niche but important use case of RTMP streaming workflows and legacy platforms that still require the Flash Video container format.
