我正在使用 ffmpeg 3.2.7，我在将 ts 文件无损转换为 mkv 时遇到问题。
源文件是使用 dumprtp 录制的转储 IPTV 流(来自 dvbstream 0.5)。
ffmpeg -i Test.ts -map 0:0 -map 0:2 -vcodec copy -acodec copy -f matroska Test.mkv
转换成功，但输出文件每隔几秒像素化一次。

当我用 MKVToolnix 转换它时，一切看起来都很好。

有没有人有解决这个问题的方法？
也许有一些选项可以正确同步流？

这是一个示例输出:

# ffmpeg -i Test.ts -map 0:0 -map 0:2 -vcodec copy -acodec copy -f matroska Test.mkv

我无法重现您使用多个播放器正常播放的输入流。 .ts 在所有强硬玩家中看起来都比 mkv 好，我猜是由于 .ts 中的纠错信息，但最终它并不能 100% 正常播放。查看 ffplay 的输出有很多与 mpeg 相关的错误，这意味着您的流转储中没有所有视频数据来正确解码。

不幸的是，您无法在没有解码和重新编码的情况下将碎片化 .ts 文件中的直接流复制到帧精确容器中，我担心。
