[gst-devel] Duplicates frames in h264 stream

[Sandeep Prakash]

Hi Prabhulinga,

>From your ffmpeg command line

 prabhu at prabhu:avi $ ffmpeg -v 5 -i sample.avi -f null -
 Input #0, avi, from 'sample.avi':
   Duration: 00:00:00.00, start: 0.000000, bitrate: -2147483 kb/s
     Stream #0.0, 1/60: Video: h264, yuv420p, 1280x720, 1/120, 59.94
 tbr, 60 tbn, 120 tbc
 Output #0, null, to 'pipe:':
     Stream #0.0, 1/90000: Video: rawvideo, yuv420p, 1280x720,
 1001/60000, q=2-31, 200 kb/s, 90k tbn, 59.94 tbc
 Stream mapping:
   Stream #0.0 -> #0.0
   existing PPS referenced

we can also observe that the framerate is actually 60 (59.94 to be exact)
and not 30
as you are saying. So somewhere the framerate is getting modified. This
explains the 
video duration getting awry.

Can you attach some logs that will show the caps at each element. Try
setting the 
GST_DEBUG=3 env variable.

Also you can try to disable your frame completion logic and check whats the
outcome.
