I have built the linux image using the Yocto. Linux imx6qsabresd 3.10.31-1.1.0_beta+g94a7e47 #1 SMP PREEMPT Sun Oct 12 02:14:32 IST 2014 armv7l GNU/Linux root@imx6qsabresd:/unit_tests# gst-launch-1.0 --version gst-launch-1.0 version 1.2.3 GStreamer 1.2.3 Issue ==== I want to play an elementary stream of H264 video at a configurable (not at runtime) frame rate. Also I do not want to drop any frames and hence not using videorate plugin. I tried setting the caps to convey the desired frame rate but at the end of execution I am getting 30fps for all elementary streams I have tested with. But the same content plays at correct FPS in gst-0.10 vpu plugin. Following are the logs for both pipelines. Any suggestions regarding debugging the issue are welcome. Please let me know if should provide any specific information regarding my setup. Thanks.
