时时刻刻ffmpeg告诉我
myfile.avi: Protocol not found
Did you mean file:myfile.avi
如果执行ffmpeg -i myfile.avi -vcodec copy -acodec copy -pix_fmt yuv420p myfile.mp4.
使用ffmpeg -i file:myfile.avi -vcodec copy -acodec copy -pix_fmt yuv420p myfile.mp4then 失败：
file:myfile.avi: Protocol not found
Did you mean file:file:myfile.avi
重新启动后（通常我只是进入）执行相同的操作（在 bash 历史记录之外）可以正常pm-suspend-hybrid工作，如预期的那样从 .avi 转换为 .mp4。
有什么想法可能是什么原因以及如何解决这个问题吗？
完整的输入/输出：
$ ffmpeg -i myfile.avi -vcodec copy -acodec copy -pix_fmt yuv420p myfile.mp4

答案1
我来到这个主题只是为了给用户添加一个提示，我发现如果文件名本身包含'：'就会导致问题，因为有些程序会生成带有时间戳的文件，例如“audio 12：” 34:14.ogg"
答案2
对我来说，“未找到协议”错误是由输出文件名中的“：”引起的。删除它然后再次添加听起来像是一种解决方法和不必要的复杂化。幸运的是，我找到了解决方案 - 只需file:在文件名前面添加即可。例如，即使$file包含像“09:02:21”这样的子字符串，这也将起作用：
ffmpeg -i "$file" -acodec pcm_s16le -vcodec copy "file:${file:r:t}".mov
在上面的命令中，只有file:部分在这个答案的上下文中很重要；但如果有人想知道它的${file:r:t}作用是什么，它在 zsh shell 中会从变量中删除绝对路径和扩展子字符串$file。请注意，file:在这种情况下，输入文件名不需要它，但输出文件名需要它，即使两者都包含多个“：”字符。
答案3
@andcoz 的评论引导我走上了正确的道路：只要/usr/lib/chromium-browser/libffmpeg.so加载，问题就存在。
就我而言，这发生在一些特殊的用例中：
libffmpeg.soVivaldi 浏览器使用它来显示专有视频格式 (H.264)。
如果我通过 Vivaldi 下载文件，然后转到其下载面板，右键单击下载的文件并选择“在文件管理器中显示”，我的文件管理器将打开。它在浏览器的“上下文”中运行，因此当我更进一步，从该文件管理器会话中打开一个终端时，它也在 Vivaldi 的上下文中运行。
对我来说，这意味着设置了一些环境变量，但如果我启动正常的终端会话（不是在 Vivaldi 上下文之外），这些变量就不存在。
这些环境变量包含（除其他外）一个LD_PRELOAD=/usr/lib/chromium-browser/libffmpeg.so.由于libffmpeg.so在使用 运行我的转换时会导致加载该文件ffmpeg，因此我在终端会话中尝试了unset LD_PRELOAD，之后我的转换再次完全正常运行。
所以这就是“当时和现在”问题的来源，我只是没有意识到当从 Vivaldi 启动我的程序链时我处于不同的环境变量上下文中。
谢谢大家的帮助。
答案4
既然你有这种不可预测的行为ffmpeg（首先不起作用，但在重新启动后起作用），我认为程序安装在某种程度上破碎的。消息
WARNING: library configuration mismatch
您提供的警告表明安装过程中存在一些问题。谷歌搜索此警告会让人感觉这个问题已经存在多年，即使是全新安装，也从未完全解决。我发现最合理的解释如下
好吧，只要您将“ffmpeg”二进制文件的副本与使用不同配置构建的 libavcodec（或 ffmpeg 源包提供的任何其他库）的副本一起使用，就会打印警告。这就是“libavcodec-extra*”包的全部要点：启用附加功能。（来源）
如果您点击此链接，您将找到一些解决此问题的方法。最常见的一种是(1),(2)
sudo apt remove libavcodec-ffmpeg-extra56
但这并不适合所有人。因此，最好的解决方案可能是重新安装 ffmpeg 和/或所需的库。
ps 如果我对您的情况的理解有误，请不要对我评价太严格，如果这些有帮助，请告诉我们。
