ffmpeg fails with user-agent on rtmp stream

[Former user]

When userAgent is added to ContentURLContainer, when thumbnail retrieval requires a UserAgent, and the stream URL protocol is rtmp, the resulting ffmpeg command will fail with -user-agent unknown.

ffmpeg.exe -analyzeduration 10000000 -user-agent "Mozilla/5.0 (Windows NT 6.1)" -i "rtmp://141.8.244.56/base playpath=pt2 pageUrl=http://sportsembed.com swfUrl=http://141.8.244.56/player/player.swf live=1"

the command needs to be:

ffmpeg.exe -analyzeduration 10000000 -i "rtmp://141.8.244.56/base playpath=pt2 pageUrl=http://sportsembed.com swfUrl=http://141.8.244.56/player/player.swf live=1"

-user-agent should only be added to the ffmpeg command when the url protocol is http.

Same failure occurs with 1.4beta1 if protocol is rtsp -user-agent should only be added to the ffmpeg command when the url protocol is http.

fixed after beta 1 was released
