Memory leak in VPU Decoder

davidshabat — Thu, 05 Sep 2019 20:54:00 GMT

We've seen memory leak in VPU decoder when decoding TS over UDP stream in Gstreamer with the following command.

gst-launch-1.0 udpsrc port=3000 ! video/mpegts ! tsdemux ! h265parse ! queue ! vpudec ! queue ! kmssink

The source stream is off the shelf encoder.

The leak occurs in the function gst_vpu_dec_object_decode. When VPU_DecDecodeBuf returens VPU_DEC_NO_ENOUGH_INBUF and VPU_DEC_INPUT_USED, the code leaves the buffer allocated and moves to next frame. With our encoder it happens on all frames. It does not happen when playing a file locally.

Please advise the proper way to fix it.

Regards,

David
