I-remux ye-1 GB WebM ku-FLV ivame ukuqedwa ngamasekondi angama-5-15 ngaphandle kokulahlekelwa umgangatho. WebM idinga ukucophelela: VP8 noma VP9 ividiyo (AV1 manje) nge Vorbis noma Opus umsindo, futhi akukho okuthile okuningi. I-FLV ivame ukuphatha i-Sorrenson Spark noma i-H.264 video ne-MP3 noma i-AAC audio, efakwe kufomethi yokuhamba eyenziwe nge-RTMP delivery.
