vaapisink and multiple heads/displays
 
|
Hi,
I am hoping that someone can point me in the right direction here. I've either messed up on my end, or I am hitting some potential limitation of vaapisink... I have my (linux) X server configured with 2 heads (:0.0 and :0.1). In my (very) basic gstreamer app, I: 1. start a pipeline with vaapisink display-name=:0.0 -- this works 2. while #1 is running, I start another pipeline with vaapisink display-name=:0.1 -- this not only fails, but it also core dumps The above is all within one application/process (if I run the pipelines in different apps/processes, there is no problem). I actually hit this issue a month or so ago, and after some searching began to think that this was some context issue, but then I moved onto something else for awhile and I didn't pursue it further at the time. Any help and/or suggestions would be greatly appreciated. Best, -jim Source code is pretty basic (full app would build the pipelines without relying on gst_parse_launch()) and is included below. Also attached is a log with "GST_DEBUG=vaapi*:6,2" Output to stdout/stderr is: /dev/video0 on :0.0 libva info: VA-API version 0.40.0 libva info: va_getDriverName() returns 0 libva info: Trying to open /usr/lib64/dri/i965_drv_video.so libva info: Found init function __vaDriverInit_0_39 libva info: va_openDriver() returns 0 libva info: VA-API version 0.40.0 libva info: va_getDriverName() returns 0 libva info: Trying to open /usr/lib64/dri/i965_drv_video.so libva info: Found init function __vaDriverInit_0_39 libva info: va_openDriver() returns 0 libva info: VA-API version 0.40.0 libva info: va_getDriverName() returns 0 libva info: Trying to open /usr/lib64/dri/i965_drv_video.so libva info: Found init function __vaDriverInit_0_39 libva info: va_openDriver() returns 0 /dev/video1 on :0.1 ** (2windows_2displays:19650): CRITICAL **: gst_vaapi_display_get_display_type: assertion 'display != NULL' failed ** ERROR:gstvaapisink.c:992:gst_vaapisink_ensure_backend: code should not be reached Aborted (core dumped) ------ SOURCE CODE ------ #include <gst/gst.h> #include <gst/video/videooverlay.h> #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <X11/Xlib.h> GstElement *pipeline1; GstElement *pipeline2; int main(int argc, char *argv[]) { GstBus *bus1; GstBus *bus2; GstMessage *msg1; GstMessage *msg2; int mydata = 1; XInitThreads(); /* Initialize GStreamer */ gst_init (&argc, &argv); /* Build the pipeline */ printf("/dev/video0 on :0.0\n"); pipeline1 = gst_parse_launch("v4l2src device=/dev/video0 ! video/x-raw,format=I420,width=1920,height=1080 ! vaapisink sync=false display-name=:0.0", NULL); /* Start playing */ gst_element_set_state (pipeline1, GST_STATE_PLAYING); sleep(5); /* Build the pipeline */ printf("/dev/video1 on :0.1\n"); pipeline2 = gst_parse_launch("v4l2src device=/dev/video1 ! video/x-raw,format=I420,width=1920,height=1080 ! vaapisink sync=false display-name=:0.1 display=1", NULL); /* Start playing */ gst_element_set_state (pipeline2, GST_STATE_PLAYING); sleep(10); printf("done\n"); gst_element_set_state (pipeline1, GST_STATE_NULL); gst_object_unref (pipeline1); gst_element_set_state (pipeline2, GST_STATE_NULL); gst_object_unref (pipeline2); return 0; } _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |
