Su, Jia

we don't have this problem on our android 6.0 devices. could you provide more info ? the crash log ?

it seems crashed when navigate folders on your sdcard. there are files named with invalid UTF-8 characters. you could delete the files like '新建文本文�' to workaround.

这个问题已解决，请更新SDK版本，具体版本请查看release note

能提供url吗

@JakeRed 从您提供的日志来看，此时应该录制也是失败的。关于录制，正常的调用日志应该是这样的 12-28 14:29:29.765 1522-27679/com.ksyun.media.streamer.demo D/streamer: Opening output file for writing at path /sdcard/test.mp4 12-28 14:29:29.812 1522-27679/com.ksyun.media.streamer.demo D/streamer: file_pub write header 12-28 14:29:32.287 1522-27679/com.ksyun.media.streamer.demo D/streamer: file_pub write trailer 12-28 14:29:32.288...

切换网络的话，需要重新连接的。这个逻辑需要app自行处理
