Segment fault when transcoding

We are using tx2 for transcoding. When closing the encoding codec, we encounter a segment fault. The log is as follows:

<2018-12-05 08:36:33.218> [ERROR] deleteCodec: Session progress is no relay.

The SDK version we are using is R28.1.0.
The decoding/encoding format is H264, which turns on the twopass-cbr mode.
Please help solve it, thank you very much!

Do you use gstreamer or tegra_multimedia_api?

Hi, DaneLLL,

We use tegra_multimedia_api.

Please share a patch on 00_video_decode or 01_video_encode so that we can reproduce your issue. Besides, can you try r28.2.1?
