We experience issues with the hardware jpeg encoding in our application (virtual memory keeps increasing). There seems to be a related post here: Libjpeg encode leak - Jetson & Embedded Systems / Jetson Xavier NX - NVIDIA Developer Forums Which was reported solved. Just to test this I ran the samp…

I just upgraded to 5.1.2 and the memory issue is not seen so far after 245k iteration. Looks like this update fixed the problem :-)

Hi, Thanks for reporting it. We will set up and try to replicate the issue.

Thanks! I also succeeded in reproducing the same issue that I see in my application code. If in line 204 in jpeg_encode_main.cpp the iteration around encodeFromFd is increased to a large amount, the virtual memory will (very) slowly fill until the application crashes. for (int i = 0; i < 10000000…

Can you give a timeline in which the above virtual memory leak will be addressed? Its delaying our work. It doesn’t seem too hard to replicate with the modified sample above?

Hi, Please apply the patch to 05 sample and try again: @@ -225,6 +225,19 @@ cleanup: } delete[] out_buf; + + if(src_dma_fd != -1) + { + ret = NvBufSurf::NvDestroy(src_dma_fd); + src_dma_fd = -1; + } + + if(dst_dma_fd != -1) + { + ret = NvBufSurf::NvD…

Hello, it doesn’t help. Still memory leak. I just change perf loop to 100’000, and try to encode with ./jpeg_encode …/…/data/Picture/nvidia-logo.yuv 1920 1080 test.jpg --perf and I got after 65000 times: PosixMemMap:84 mmap failed : Cannot allocate memory

I found one oddity encodeFromFd in the function jpeg_write_raw_data (&cinfo, NULL, 0); I tried to log the start and end of this function with “std::cout”. Afterwards I looked in strace: strace -o trace_info.txt ./jpeg_encode …/…/data/Picture/nvidia-logo.yuv 1920 1080 test.jpg --perf Cut out the…

Hi, [image] cm_cb: PosixMemMap:84 mmap failed : Cannot allocate memory We ill try to replicate the error and check further.

I forgot to mention that we have the same memory leak on NVIDIA Jetson Orin NX 16GB, Jetpack 5.1.1, L4T 35.3.1, Steps to reproduce: Change In file jetson_multimedia_api/samples/05_jpeg_encode/jpeg_encode_main.cpp “define PERF_LOOP 300” to “define PERF_LOOP 100000” run 05 sample with ./jpe…

I’m facing same issue. GStreamer’s nvjpegenc element has been affected similarly.

Facing the same issue on jetson xavier nx with jetpack 5.1.1. Running the same encoder on the same m_dmabuf file descriptor: m_JpegEncoder->encodeFromFd(m_dmabuf, JCS_YCbCr, &buffer, size, m_image_compression); resulted in the mentionned PosixMemMap:84 mmap failed : Cannot allocate memory error. …

Hi DaneLLL,
I also face this problem, and my jetpack version is 5.1.1. But I don’t want upgrade all jetpack in my board, can I only change libnvjpeg.so？
Thanks!
