Hi,

We are trying to play 2 videos simultaneously. But when trying to start second video, pipeline getting exited. And individually 2 videos are playing. so there is no issue with video files.

Gstreamer version gstreamer-0.10.36

Software - 4.14.98 kernel and yocto release. SOC - imx8dx.

Please find the below pipelines.

gst-launch-1.0 filesrc location=1.mp4 ! decodebin ! imxvideoconvert_g2d ! waylandsink window-width=1280 window-height=720 &
GST_DEBUG=3 gst-launch-1.0 filesrc location=2.mp4 ! decodebin ! imxvideoconvert_g2d ! waylandsink window-width=1280 window-height=720 

Plese find the log when start to play 2 video after 1st video started.

0:00:00.20751[ 896.850084] vpu-b0 2c000000.vpu_decoder: dma_alloc_coherent of size 1572864 failed

if suspect is correct, then how much memory do we need to allocate? 1572864 how it is calculated. 

if suspect is not correct, please help us to solve this issue.

Thanks,
