    We are successfully able to upsteam video on wowza server. In result we get file with (.flv) extension . Now we want to downstream video on android phone. But we are not able to play .flv file, We can easily play video file with .mp4 extension . We need to downstream .flv file from RTMP url. Following is URL

    OUTPUT:- test.flv
    Format:- flv

    What i tried to get .mp4 file

    OUTPUT:- crash
    Format:- mp4

    One more thing i.e I treid

    OUTPUT:- Two files named(test.mp4, test.mp4.tmp)
    Format:- flv

    2) Second we would know how to live stream video with .flv extension on android devices.

    If you add "mp4:" prefix to stream name in the encoder (or StreamManager in the case of MediaCaster streams), then Wowza records to mp4 container.

    Stream name "mp4:test" will record to test.mp4

    .flv is not supported in this case. If the .flv contains h.264 and aac or mp3 audio you can transcode with ffmpeg like this:
    ffmpeg -i infile.flv -acodec copy -vcodec copy outfile.mp4
    Take a look at this article also:
    How to encode video on demand content

    If the .flv contains h.264 video and aac or mp3 audio, it might work in some cases by adding mp4: prefix to the stream or file name, in the playback URL.
