[Asterisk-video] error with app_transcoding

[Mário Dias]

Hello! I just try reinstall ffmpeg in other version of linux (ubuntu)
and the before error not appear now.

But, When I call 5001, the video call answer but not appear the video
(waitting remote video) in X-lite4.

In asterisk logs there are:

[Feb 25 17:46:54] WARNING[18490] app_transcoder.c: >Transcoding
[,s at camera,h263 at qcif/fps=10/kb=52/qmin=4/qmax=12/gs=50,180004]
[Feb 25 17:46:54] WARNING[18492] app_rtsp.c: >rtsp play
[Feb 25 17:46:54] WARNING[18492] channel.c: Unable to find a codec
translation path from 0x780004 (ulaw|h263|h263p|h264) to 0x2000
(nothing)

why ???

I remember that I allowed in sip.conf : video support, h263, h263p, h264

I want transcode the codec of received video RTSP streaming (codec
mp4v) to H263 of my softphone.....
