Hi,
I'm a newer of GStreamer Vaapi user, I compiled and installed GStreamer-1.4.5 and VaAPI-0.5.10 (the lasttest version).
Then, I tried to test vaapiencode_h264 plugin, there's a problem that successed to connect all elements but cannot run the pipeline.
When I saw the debug details, there is message that 'context pad peer query failed',
Actually, I don't know what and why the context pad peer query failed, and also don't know how to fix this problem, do I need to change sth. in the pipeline?
Although I tried to search the answer from internet, I cannot find many information about it.
Thanks for any hint on what I'm doing wrong.
Best regards,
Nicholas
