Hi,
My problem is raised at [url]https://devtalk.nvidia.com/default/topic/1006857/jetson-tx1/-mmapi-under-what-conditions-lsquo-conv-gt-capture_plane-qbuffer-rsquo-will-block/?offset=12#5145680[/url]
Hi DaneLLL,
Thank you for your reply.
It not failing at second time, often fails at the the stop and release.
When stop and release, the program is as follows.
dec->output_plane.setStreamStatus(false);
dec->capture_plane.setStreamStatus(false);
dec->output_plane.stopDQThread();
conv->output_plane.setStreamStatus(false);
conv->capture_plane.setStreamStatus(false);
enc->output_plane.setStreamStatus(false);
enc->capture_plane.setStreamStatus(false);
conv->output_plane.stopDQThread();
conv->capture_plane.stopDQThread();
enc->output_plane.stopDQThread();
enc->capture_plane.stopDQThread();
delete conv;
delete enc;
delete dec;
It will block at “enc->capture_plane.stopDQThread()”, I debug it by gdb, then I see it block at wait the exit of “dqThread”, and the “dqThread” is block at “plane->dqBuffer”. dec/enc/conv is created with “O_NONBLOCK”.
Sometimes it will encounter a segment fault at “delete enc”.
Thank you!
