What happens if you don't call flush()?

[WLGQD]

What is written in hs_err_pid117652.log is FFmpegFrameRecorder.flush() . I didn't call FFmpegFrameRecorder.flush()

[saudet]

Your crash log says that you're calling flush(). Please try without calling flush().

BTW, it's probably easier to use the ffmpeg program: http://bytedeco.org/javacpp-presets/ffmpeg/apidocs/org/bytedeco/ffmpeg/ffmpeg.html When that crashes, it doesn't bring down the JVM, so we can recover.

1.the log says FFmpegFrameRecorder.flush() .But I didn't call FFmpegFrameRecorder.flush() explicitly, there is a call to flush() in the source code FFmpegFrameRecorder.close().

  public void stop() throws Exception {
        if (oc != null) {
            try {
                flush();

                /* write the trailer, if any */
                av_write_trailer(oc);
            } finally {
                release();
            }
        }
    }

I don't see where you're calling close(). You'll need to call that or it might not work well, that's normal.

sorry misspelled， , i call .stop(), there is a call to flush() in the source code FFmpegFrameRecorder.stop().

try {
                if (null != recorder){
                    recorder.stop();
                    recorder.release();
                }
            } catch (FFmpegFrameRecorder.Exception e) {
                log.error("关闭recorder失败, inputFile:{}", videoFile, e);
            }

Does it crash with other formats than wav?
