Describe the current behavior
Customer uses MediaSDK sample sample_multi_transcode and wants an 88 composition for NVR use case. because there will be not all 88 input streams enabling at the beginning, they will dynamically enable the input streams during playback, and the dynamically enabled input streams are possibly at any grid of the layout. Here is a layout that will always cause GPU Hung after playing for 2-3s. the layout is defined in n64_38_tile.par(in attached), I draw the layout as below for a visual look, the composition output surface is 25601440, tile number is 5, the first input stream is starting from (640540), all the input streams’ size in Composition output surface is 320*179. I placehold the first 3 lines and the first 2 grids of the fourth line which have not input streams at the beginning.
Work around fixed:
This GPU Huang can be fixed by below methods:
• First method: Change the tile0 y from 540 to 537(537 = H:179 *3 )
• Second method: Change the tile0 H from 179 to an even number:178 or 180. Please note that the odd numbers such as 177,175 will cause GPU Huang.
In the Addition, below cases based on this layout also will not meet “GPU HUNG”.
• If there is only the first grid absent in the fourth line, not meet “GPU HUNG”.
• If there are first 4 grids absent in the fourth line, not meet “GPU HUNG”.
• If there is no absent grid in the fourth line(8 input streams is full), not meet “GPU HUNG”.
• If it does not submitted composition with user tiled customized, not meet “GPU HUNG”.
Describe the expected behavior
No GPU HANG
