E/MediaMetadataRetrieverJNI: getFrameAtTime: videoFrame is a NULL pointer

I recorded a video in SamsungS7 edge back camera, I have integrated Camera-2-API in my project, I try to trim video at this moment this crash will happen, I maintain resolution for recording is 1920x1080 resolution.
Here is my log.

I/System.out: VIDEO_FRAMES_WIDTH:1160

Thank you for feedback!
Sometimes you may not get the bitmap of the key frame of the video.
So you need to make a legal judgment on the acquired bitmap.
