transcoding from mpegts to h264

[vandanachadha]

I am trying to encode the dvbsrc into h264, but the output file is 0  bytes.

gst-launch-1.0  --gst-debug-level=3 dvbsrc  modulation="QAM 256"
frequency=147000000 num-buffers=1000 ! tsdemux  name=demux! queue ! x264enc
qp-min=18 ! filesink location=test_x264enc.ts
