Vieo stream sample

Pipeline stops with negotiation problem. Debug show message:

gst_video_encoder_setcaps:<avenc_flv0> rejected caps video/x-raw, format=(string)I420, width=(int)1280, height=(int)720, pixel-aspect-ratio=(fraction)1/1, interlace-mode=(string)progressive, colorimetry=(string)bt709, framerate=(fraction)0/1

I try to convert with this:
  gst-launch-1.0 filesrc location=h264.ts ! decodebin ! videoconvert ! avenc_flv ! flvmux ! filesink location=test.flv

Attached sample works fine in 0.10. Perhaps the problem is from an unknown frame rate?

    avenc: Choose 25 fps if we don't have any in the caps
    
    Some encoders require a non-zero framerate to be configured properly
    and just choosing something will make them not fail completely at
    least.
