           Summary: interlaced video: Patches in output video and time
                    stamp calculation issues with network input
    Classification: Platform
           Product: GStreamer
           Version: 1.0.4
        OS/Version: Linux
            Status: UNCONFIRMED

I am using gstreamer(version 1.0.4). I have a ts file(it is 100MB file,
download it using following link), its details are given below. My pipeline is:

test.ts link:
https://docs.google.com/file/d/0Bx2DzyzsJg9YYmxRNXUwejYzOGc/edit?usp=sharing

gst-launch-1.0 udpsrc port=10000 ! decodebin ! deinterlace mode=0 fields=1
method=4 tff=0 ! tee ! queue ! videoconvert ! videoscale !
video/x-raw,width=640,height=360 ! x264enc tune=zero-latency ! filesink
location=out.264

When I recieve my test.ts file through network over udp I am seeing patches in
the output video after 6000 frames. Also video is running twice faster than
audio(because video timestamp is half of audio timestamp), No avsynch at all.
Finally it leads to pipeline hang(all threads are in pthread_cond_wait
mode)!!!. This is repeatable and with roughly the same pattern so it's quite
interesting. If I remove the encoder from the pipeline(see below given
pipeline) I dont see any issue at all. Surprizing!!! I have validated the
network input, its perfectly fine.

gst-launch-1.0 udpsrc port=10000 ! decodebin ! deinterlace mode=0 fields=1
method=4 tff=0 ! tee ! queue ! videoconvert ! videoscale !
video/x-raw,width=640,height=360 ! filesink location=out.yuv

If I repeate the same experiment with test.ts as fileinput through filesrc I
dont see any issue.!!!
