Unable to find a suitable output format for '/storage/emulated/0/vff/out/20190702085518.mkv'

为什么在win上使用FFmpeg环境，直接使用命令对视频文件进行转码，可以成功，但是在这个sdk中使用相同的命令却不成功呢？例如 ffmpeg -i /storage/emulated/0/DCIM/Camera/20190702085518.mp4 -c:a copy /storage/emulated/0/vff/out/20190702085518.mkv

将MP4文件转码成MKV文件，错误log ffmpeg -i /storage/emulated/0/DCIM/Camera/20190702085518.mp4 -c:a copy /storage/emulated/0/vff/out/20190702085518.mkv 07-12 15:38:50.725 4962-5110/com.fcbb.vff.android D/vff-->::
