The Android version Jelly Bean permits FLV files for use by consumers. FLV files can only be viewed using FLV player software. Screen capture & recorder tools can capture FLV videos from the screen. As the initial codec files recognized by the Flash Player and due to their widespread use, FLV files utilizing the H.263 specification under its Sorenson Spark codec are regarded as being compliant. You can use the Nellymoser Asao Codec for recording audio over a video utilizing a microphone and converting the audio to an MP3 file category. You can share a screen in two ways, with the use of a bitmap tile as well as lowering the color depth of the image.
