Command:
gst-launch-1.0 playbin uri=rtsp://192.168.1.88:556/vga
The memory of gst-launch-1.0 will increase more than 30M every hour, then the video stop, but audio soud ok。
Delete the libgstvpu.so , use the same commad. memory will not increase, but play the high resolution (1920x1080) not smooth.
Anybody has faced the same problem and resolved? Please help
I do more test.
Compare playing local video file and RTSP:
1) play 1920x1080 ((MPEG4\AVC_H_L3)local files, that seems not has memory leak. (log file : gplay-test-AVC_H_L3_Schindlers.log、gplay-test-MPEG4_Schindlers.log)
2) play 1920x1080 (AVC_H) RTSP, memory increase about 16M. (log file: gplay-test-AVC_H_RTSP.log)
Compare playing RTSP(960x540 AVC_H) with vpudec and avdec_h264 lib:
a) use vpudec , memory increase about 10M in 20 mins.( log file: gplay-test-AVC_H_RTSP_with_VPU.log)
b) use avdec_h264(delete /usr/lib/gstreamer-1.0/libgstvpu.so) , memory not increase. (log file: gplay-test-AVC_H_RTSP_with_avdec_h264.log)
CPU: IMX6DL
Kernel: 4.1.15
BSP: 2.0.1 GA
vpudec: imx-gst1.0-plugin-4.1.4
avdec_h264:gst-libav-1.8.1
又对比测试了gstreamer0.10 的版本, 使用mfw_vpudec解码,是没有内存泄漏的。
内核是使用相同的4.1.15, 所以应该跟硬件没有关系。
我们的产品已经出货1年多,最近测试高分辨率的流媒体才测试出来了,如果重新换回gstreamer0.10,工作量有点大(而且好像yocto无法同时编译gstreamer0.10和qt5),请帮忙分析和解决gstreamer1.0下的libgstvpu.so内存泄漏问题。
I have already use the new version with yocto imx-yocto-L4.14.78_1.0.0_ga, still face the same problem.
Does anyone can give some advice?

It may help with gstreamer memory leak.
Have a great day,

Thanks for your replay.
I follow the patch patch_v4l2_issue.zip , but not find any about v4l2 in arch/arm/mach-imx/mach-imx6q.c.
So I just modify videobuf-dma-contig.c, drivers/media/video/mxc/output/mxc_vout.c and drivers/mxc/vpu/mxc_vpu.c.
But the memory still increase more than 40M per hour.

Hi jiaxingliang,
Did you ever find the cause of the memory leak?
