Thanks. It produces 16M, 20M bitrate TS files.
It is very strange. The link says that the max bit rate is 40Mbps (40000 with 1000bps unit) for main tier. Do I miss anything here? Encoded video doesn't show level on MediaInfo.

Higher tier max bit rate is 160,000 which is even bigger. It should be read as 160M not 16M. See the unit is kbps not bps.

Max bit rate for Main and Main 10 profiles (1000bits/s)[A

SVT [Error]: Instance 1: Out of bound maxBufferSize for level 5.1 and tier 0
[libsvt_hevc @ 0x351e140] Error setting encoder parameters

You should read the error message carefully to adjust the encoder parameters.

When setting wrong parameter, the plugin broke and coredump happened. This one is already fixed. Please try to the latest plugin version.

I read the error message about maxBufferSize. However where did the restriction come? I do not see this restriction from the provided link. X265 is just fine with the same setting (main10, level 5.1).

The restriction comes from SVT-HEVC lib.

    static EB_U32 mainTierCPB[TOTAL_LEVEL_COUNT] = { 350000, 1500000, 3000000, 6000000, 10000000, 12000000, 20000000, 25000000, 40000000, 60000000, 60000000, 120000000, 240000000 };

    if ((config->level != 0) && (config->rateControlMode) && (config->tier == 0) && ((config->targetBitRate * 3) > mainTierCPB[levelIdx])) {
    SVT_LOG("SVT [Error]: Instance %u: Out of bound maxBufferSize for level %s and tier 0 \n",channelNumber+1, levelIdc);
    return_error = EB_ErrorBadParameter;
}

SVT-HEVC is on Github, which you have access to its code.
