到目前为止,我只有空格和单引号需要处理,所以我在它周围加了双引号
#!/bin/bash
#ffmpeg -i Muppets\ Most\ Wanted_KBYUT_2017_07_08_18_56_00.wtv -f ffmetadata metadata.txt
#ffmpeg -i Gene\ Roddenberry\'s\ Andromeda_COMET_2017_12_14_20_05_51.wtv -f ffmetadata metadata1.txt
find . -type f | grep 'wtv$' | while read file; do
echo "----"
echo "----"
echo "----"
echo "$file"
ls -alh "$file"
echo "$file.txt"
#ffmpeg -i "$file" -f ffmetadata "$file.txt"
done
打印出来

看起来不错,所以我尝试让 ffmpeg 做它的事情,通过取消注释一行,我得到

第一个文件有效,但第二个文件丢失了前导点,将相对路径更改为绝对路径。我尝试了文件夹中的 3 个文件,其中 2 个有效。 4 个文件 2 个工作。 6 个文件 3 个工作。
答案1
前导“.”正在被ffmpeg
(当它询问流映射时)消耗,它与read
.
您应该使用find
的功能:
find . -type f -name '*wtv' -ls -exec ffmpeg -i {} -f ffmetadata {}.txt \;
这会查找名称以 结尾的文件wtv
,显示其详细信息(这是一个 GNU 扩展;-print
如果您find
不支持,请使用ls
),然后运行ffmpeg
它们。
