Linux/DRA746: waylandsink: How to fit to screen/display resolution with videos larger/smaller than it?

Hi Vikash,
Current version of Linux SDK doesn't support resizing with waylandsink plugin as there are no properties to set the resolution of the window.
But you can modify waylandsink plugin to hardcode window size for your display resolution with wl_viewport_set_destination() call.
TI has a patch for to set window-resolution with properties, we will push the patch after review and share you the information.

Hi Ramprasad,

Thank you for quick reply. Yes, currently I am using wl_viewport_set_destination(). Could you share the patch? Do you know when it will it be available?

Hi Ram,

Could you share the patch for this so we could test?

Hi Ram,

For i.MX6 we do not use waylandsink. Instead we are using "glimagesink". Could you please tell ETA for this?

Hi Ram,

I have integrated and built the waylandsink. However it is not working as expected.

I tried with the below command and on display video comes for only 768x464.

gst-launch-1.0 playbin uri=file:///home/root/TearOfSteel-AV-Short-720x420.mp4 video-sink=waylandsink sync=false window-resolution=800x480

Also I was using below change previpusly and I removed it in my above testing? Do I need to keep this change also?

static void
gst_wl_window_resize_video_surface (GstWlWindow * window, gboolean commit)
{

//wl_viewport_set_destination (window->video_viewport, res.w, res.h);
wl_viewport_set_destination (window->video_viewport, 800, 480);

Hi Vikash,

If my patch is applied, no need to hardcode .

Can you first try the pipeline for explicit pipleline and not playbin?

If you are using playbin, then video-sink property should be set as shown below , i,e use " "

gst-launch-1.0 playbin uri=file:///home/root/TearOfSteel-AV-Short-720x420.mp4 video-sink="waylandsink sync=false window-resolution=800x480"

 

Can you try this ?

Hi Ram,

I tested with following pipelines and it seems to work fine.

1. video with 1280x720
gst-launch-1.0 filesrc location=/home/root/B01_Baseline1.0_1280_720.MP4 ! qtdemux ! h264parse ! ducatih264dec ! waylandsink window-resolution=800x480

Result: Works fine.

2. video with 800x480
gst-launch-1.0 playbin uri=file:///home/root/TearOfSteel-AV-Short-720x420.mp4 video-sink="waylandsink window-resolution=800x480"

Result: Works fine.

3. video with 640x360
gst-launch-1.0 playbin uri=file:///home/root/Ep1.mp4 video-sink="waylandsink window-resolution=800x480"

Result: Works fine.

If I add "sync=false" then resolution is fine but it seems video is fast forwarding.

Thank you Ram for your kind support.
