เกี่ยวกับการแปลง MP4 เป็น FLV
MP4 to FLV conversion repackages your MPEG-4 video into the Flash Video container format. FLV was the dominant streaming format of the mid-2000s, powering the original YouTube, Newgrounds, and countless Flash-based video players. While Adobe officially discontinued Flash Player in December 2020, FLV remains relevant for legacy content management systems, RTMP live-streaming workflows, and archival of era-specific web content.
Our converter uses FFmpeg to transcode MP4 video to the Sorenson Spark (H.263) or VP6 codec and audio to MP3 or ADPCM within the FLV container. Alternatively, H.264 video can be muxed into FLV directly for RTMP-compatible output.
ทำไมต้องแปลง MP4 เป็น FLV
The primary modern use case for FLV is RTMP (Real-Time Messaging Protocol) streaming. Many live-streaming servers including Wowza, Nginx-RTMP, and some CDN ingest points expect FLV-wrapped H.264 streams. OBS Studio and similar broadcasting software output FLV for RTMP delivery. Additionally, organizations with legacy CMS platforms built during the Flash era may still require FLV files for their video libraries until they complete their migration to HTML5.
