请帮助我，希望将特定的 ffmpeg 参数包含在我的视频编码中。
我的工作只与视频流有关，所以这是我唯一要更改的。
我收到一个已经为特定广播公司预编译的 .mov 文件，其中一些自包含视频有 4 个流(1 个视频、2 个音频和其他一些时间码流)。其他有多达 17 个流:1 个视频流、15 个音频流，最后一个是不支持的 tmcd。
我的流程管道包括仅重新编码/重新处理视频 流，以及我需要传递给输出文件的所有其他内容 - 所有其他流没有任何更改或更改。
在此编码步骤中，我将 icon.png 从 sec 2-3、4-5 和 6-8 插入到位置 5:21。为此，我使用了 map 选项，因此我的编码字符串如下所示:
ffmpeg -i in.mov -i icon.png -i icon.png -i icon.png
-filter_complex " [0][1]overlay=5:21:enable='between(t,2,3)'[v1];
[v1][2]overlay=5:21:enable='between(t,4,5)'[v2];
[v2][3]overlay=5:21:enable='between(t,6,8)'[v3]" -map '[v3]' -map 0:a
-c:v dvvideo -pix_fmt yuv422p -b:v 115084915 -maxrate 115084915 -minrate 115084915 -r 29.97 -top 1 -color_primaries bt709 -color_trc bt709 -colorspace bt709 -vtag dvh6
-c:a copy -c:s copy -y out.mov
阅读其他一些stackoverflow帖子，我发现了一种传输所有其他流的方法，即使用-map 0:
但是当我尝试添加 - map 0 在我的最后一行:
...
-map 0 -c:a copy -c:s copy -y out.mov
如果我删除 map “[v3]”- map 0:a 从我的原始编码字符串中并且只包含 -map 0，我得到了正确数量的流，但是，当然 icon.png 没有在正确的时间插入。我应该怎么办？
如果有办法将我的 -filter_complex 重新映射到覆盖图像而不使用此 - map 选项？或者，具体说明每个 - map 指的是？
如果没有，我可以使用哪些其他参数/参数(如果甚至存在这样的选项)来复制所有流、子和所有其他音频，如果存在的话，可能还有其他用于音频损伤的信号。
请帮忙，这样我终于可以包装我的输出并提交我的工作了。

最佳答案
有条件地映射所有非视频流(即包括如果存在)。复杂过滤器图的输出会自动映射到第一个输出，因此不需要手动映射。复制除视频之外的所有流。您可以将单个叠加实例用于多个时间范围。ffmpeg -i in.mov -i icon.png -filter_complex "[0][1]overlay=5:21:enable='between(t,2,3)+between(t,4,5)+between(t,6,8)'" -map 0:a? -map 0:s? -pix_fmt yuv422p -r 30000/1001 -c copy -c:v dvvideo -b:v 115084915 -maxrate 115084915 -minrate 115084915 -top 1 -color_primaries bt709 -color_trc bt709 -colorspace bt709 -vtag dvh6 -y out.mov
