An Unexpected Error

[HesamAsad]

Hi! I've just used the app and encountered an unexpected error: Stream specifier ':v' in filtergraph description color=s=1280x720:c=black [base]; [0:v] setpts=PTS-STARTPTS+55157, scale=280x280 [lowerright];[1:v] setpts=PTS-STARTPTS+11907, scale=1280x720 [screenshare_2_3];[2:v] setpts=PTS-STARTPTS+109729, scale=1280x720 [screenshare_5_7];[3:v] setpts=PTS-STARTPTS+115599, scale=1280x720 [screenshare_3_5];[base][screenshare_2_3] overlay=[tmp0];[tmp0][screenshare_5_7] overlay=[tmp1];[tmp1][screenshare_3_5] overlay=[tmp2];[tmp2][lowerright] overlay=x=1000:y=480 matches no streams. also my files list after running the command is like this:

Camera.mkv             ftchat0.flv      sco_metadata.xml
cameraVoip_1_4.flv     ftchat0.xml      screenshare_2_3.flv
cameraVoip_1_4.xml     ftcontent1.flv   screenshare_2_3.xml
cameraVoip_4_6.flv     ftcontent1.xml   screenshare_3_5.flv
cameraVoip_4_6.xml     ftstage2.flv     screenshare_3_5.xml
cameraVoip_4_8.flv     ftstage2.xml     screenshare_5_7.flv
cameraVoip_4_8.xml     indexstream.flv  screenshare_5_7.xml
cameraVoip_4_9.flv     indexstream.xml  telephony-files.xml
cameraVoip_4_9.xml     mainstream.flv   transcriptstream.flv
document-metadata.xml  mainstream.xml   transcriptstream.xml

The Camera.mkv file is alright and includes just the audio of the session. But there's a problem merging them with the videos. I'd be glad if you can help me. Thanks.
