[Asterisk-video] symbol lookup errors sws_getContext

[matteo crivellaro]

Hi,
my webcam (Linksys WVC54GCA) supports the rtsp mobile streaming (I think it is 3gp).
A part of my dialplan is:


[asgard]
exten=>goblin,1,h324m_gw_answer() exten=>goblin,n,transcode(,s at camera1,h263 at qcif/fps=10/kb=52/qmin=4/qmax=12/gs=50)

[camera1]
exten => s,1,Answer
exten => s,2,rtsp(rtsp://20.1.1.2:554/12345)
exten => s,3,HangUp


where 12345 is the code required by webcam and 554 is the rtsp port.

When I start a video call appear the following errors:

WARNING: app_rtsp.c:1037 rtsp_play: >rtsp play
WARNING: app_transcoder.c:963 app_transcode:>Transcoding[,s at camera1,h263 at qcif/fps=10/kb=52/qmin=4/qmax=12/gs=50]
WARNING: channel.c:2781 set_format: Unable to find a codec translation path form unknown to unknown
asterisk: symbol lookup error: /usr/lib/asterisk/modules/app_transcoder.so: undefined synbol: sws_getContext

Can you help me?

Regards, Matteo.
