I have created a standalone script, the file and the video file can be found in the following location: <a href="https://drive.google.com/open?id=14Qss_2-EBeRb5k204pcoIz7_AgmR1FRl" style="color:rgb(5,99,193);text-decoration:underline" target="_blank">https://drive.google.com/open?id=14Qss_2-EBeRb5k204pcoIz7_AgmR1FRl</a> <a href="https://drive.google.com/open?id=15xZ1wcuQBN7pPxU7Ru08hSR7YagUQV6w" style="color:rgb(5,99,193);text-decoration:underline" target="_blank">https://drive.google.com/open?id=15xZ1wcuQBN7pPxU7Ru08hSR7YagUQV6w</a> The GDB stack trace from my machine can be found here: <a href="https://drive.google.com/open?id=1M8Srjd1Qp4Y8C8Edepme2lwzzWSpOZM3" style="color:rgb(5,99,193);text-decoration:underline" target="_blank">https://drive.google.com/open?id=1M8Srjd1Qp4Y8C8Edepme2lwzzWSpOZM3</a> The stall seems to be appearing in gst_element_seek_simple ().

That is where the STALL happens.</li> </ol> I have put the number of iterations to be 5000 but usually the stall appears in around 200-300 iterations. Can you please confirm if this is a bug in Gstreamer and if there is a way to avoid the stall while reading the file using Gstreamer? Thanks! </div> </blockquote></div> </div>
