我正在尝试使用 FFmpeg 压缩一些包含多个流的视频，其中一些流无法被 FFmpeg 识别：
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'GX010686.MP4':

当我使用 时ffmpeg -i $file -c:v libx265 -crf 23 -c:a libvorbis -q:a 5 $newfilename，只有音频和视频流最终出现在新文件中。因此我尝试了ffmpeg -i $filename -map 0 -c copy -c:v libx265 -crf 23 -c:a libvorbis -q:a 5 $newfilename，但这给了我以下错误：
[mp4 @ 0xf974ce7d500] Could not find tag for codec none in stream #2, codec not currently supported in container
Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument
Error initializing output stream 0:0 --
我知道 FFmpeg 不理解这些附加元数据，但它不需要理解。我怎样才能将带有编解码器的流复制none到新文件中？
