Problem Description:
I use sample_multi_transcode to transcode a HEVC rtsp stream to h264 rtsp stream using hevc plugin. I want to test the concurrency performance parameter.So i write a shell script using for loop to simulate concurrency execution.But error happens when i execute the program twice or more.The sample_multi_transcode are killed .I notice that the cpu/gpu overload is too large.
If i don't use the hevc transcode function ,for example ,just transcode a h264 stream to a different resolution rate h264 stream. I use the similiar shell script which is commenting out "echo set -i::h265 15dd936825ad475ea34e35f3f54217a6 .The error won't happen.
I trace the problem . And i can get the information as belows:
clone(child_stack=0x2b43c1785fb0,flags=CLONE_VM|CLONE_FS|CLONE_FILES|CLONE_SIGHAND|CLONE_THREAD|CLONE_SYSVSEM|CLONE_SETTLS|CLONE_PARENT_SETTID|CLONE_CHILD_CLEARTID, parent_tidptr=0x2b43c17869d0, tls=0x2b43c1786700, child_tidptr=0x2b43c17869d0) = 15861
futex(0x2594bdc, FUTEX_WAIT_BITSET_PRIVATE|FUTEX_CLOCK_REALTIME, 1, {1518088586, 477932000}, ffffffff) = -1 ETIMEDOUT (Connection timed out)
It occures many times.
