wingchun22 : on the ffmpeg docs it does metion info to join flv to flv then follow the example. wingchun22 : are you sure its not possable yes. : i have seen examples on the net where images have been joined to mp3 to produce flv files do you mean you just want to take the audio from the flv? that you can do. if you mean you want to append two sections of video, you need to incorporate more tools. probably easiest, create flv1 from pic and audio with ffmpeg, merge fl1 with main flv, with flvbind or flvmerge(i think). encode final flv to 3gp. tripp
