<div dir="ltr"><div><div><div><div>Because of this suspicion, I ran without the tool at very low resolutions and used windows' right-click mini-dump feature. I then post processed these dumps and found the same exact objects, the 68 byte BufferPacket structure and the 10k BufferPackets growing. Surprisingly they are not in lock step, the number of structs and buffers are not the same. I ran this test on 2 windows 7 machines and have the same leak on Linux. During the test one one machine I am using a total of 2% CPU. 5 of the 8 cores are idle and the 64bit OS is at around 5/12 GB. The process is 32 bit and these tests are discontinued when memory usage approaches 1GB. <br>
<br></div>It does seems to be timing sensitive, like we do not return soon enough so it creates a BufferPacket. The problem is it isn't releaseing them Almost like there are more buffer packets than there are scheduled or direct afterGetting calls. Not a Performance issue, just somehow missed consumer tasks. <br>
<br>The more streams or the attachment of the memory validator tool does increase the frequency of the allocations. <br><br></div>Because this software usually runs 50+ high res streams on lesser hardware, there is during this test, a surplus of consumer capability. <br>
<br></div>Tests of the newest version of live555 are scheduled. a bit of migration may be needed. Our code goes on windows, linux and embedded targets, so getting all architecture builds is not trivial. I did compare the current live555 MultiFramedRtpSource with ours and there have been a few changes. <br>

This is what I am trying to solve. When I connect the Memory Tool, there are no BufferPackets at all. After a few hours, there are a few hundred or a few thousand based on how many streams are connected. We quickly get into over a gigabyte memory usage on a 32 bit process and it gets worse from there.<br>
</div></div></div></div></div></blockquote><div><br></div></div>If this is happening, it must be because the incoming data is being consumed at a slower rate than the rate at which it is arriving. I.e., your 'Memory Tool' is causing your system to slow down so much that it can't keep up with processing the incoming streams. To avoid this, you'll need to reduce the number and/or bitrate of your incoming streams.</div>
