[FFmpeg-user] Play Camera RTSP H264 Stream

We have a Sanyo HD network cam producing the same kind of feedback, however only in the beginning. I can successfully transcode / passthrough the stream.
What is your ffmpeg command to transcode? I'm using sth like ffmpeg -i rtsp://admin:admin@ -vcodec copy -acodec copy -f mpegts udp://
Also, what is the feedback you get from ffmpeg transcoding (I'm guessing the same as in ffplay)? What confuses me is this Stream #0.2: Data: what's that?
Maybe mapping the file manually could help, therefore ignoring the Data stream e.g. -map 0.0:1.0 -map 0.1:1.1

Betreff: [FFmpeg-user] Play Camera RTSP H264 Stream

I'm trying to view a H264 stream from an Avigilon camera which has the option to create a RTSP stream.  I can view the stream succesfully n VLC so it seems as though the stream is correct?  However, when I try to view it in ffplay or transcode it in ffmpeg I repeatedly get the PPS errors below followed by a conversion error and no video.  Anyone know what the issue is or have a suggestion?
