我有机会在 64 位 arch linux 上加载二进制编解码器吗？我有一些 .dat 文件在 32 位 Windows XP 下使用 smplayer（下载编解码器后）运行良好，但在 64 位 Linux 上，我得到了扭曲的图像。
我下载了所有二进制编解码器对于 win32 在这里,
和必不可少的电子lf64 库在这里
两个档案都被提取到/usr/lib/codecs
从 strace 的输出来看，似乎/usr/lib/codecs没有加载。
PS附mplayer日志

答案1
嗯，首先，mplayer 认为这是 mpeg1，ffmpeg 可以很好地处理。或者至少，应该能够很好地处理，并且通常 mplayer 更喜欢 ffmpeg。您可以尝试通过-vfm或选项强制它使用不同的解码器-vc（将“help”传递给其中之一以获取列表）。您也可以尝试不同的-demuxer（也需要列表中的“帮助”）。
但无论如何，我不确定 64 位 mplayer 是否可以加载 32 位编解码器。您可以尝试一下 win64 编解码器包。或者，您可以安装（可能从源代码）32 位 mplayer。
答案2
它可能适用于该ia32-libs软件包和 32 位版本的mplayer.
