[Asterisk-video] Help with rtsp

Hi Sergio,

 I tried to execute app_rtsp without app_transcode, and the result is the next:

    -- Executing [8000 at default:1] Answer("SIP/5004-158c2920", "") in new stack
    -- Executing [8000 at default:2] rtsp("SIP/5004-158c2920",
"rtsp://80.37.220.217:8001/sample_100kbit.mp4") in new stack

I don´t understand how I can use app_transcode alone, can you explain me??.

Thanks in advance
