Hello

I run the follow command
gst-launch-1.0 -v filesrc location=/mnt/nfs/15.mp4 ! qtdemux ! queue ! h264parse ! omxh264dec skip-frames=2 ! queue ! fakesink

it will output the follow error message

Caught SIGSEGV
#0 0xb6d4b3f0 in poll () at …/sysdeps/unix/syscall-template.S:81
#1 0xb6dfa4e6 in ?? () from /lib/arm-linux-gnueabihf/libglib-2.0.so.0
Spinning. Please run ‘gdb gst-launch-1.0 8746’ to continue debugging, Ctrl-C to quit, or Ctrl-\ to dump core

anyone can help me solve the problems? can we control skip-frames when decode h264 using omxh264dec ?

thanks in advance.

If your goal with skipping frames is to achieve a some lower frame rate, maybe the “videorate” plugin helps you. With that you should be able to define the frame rate you want by duplicating or dropping frames.
