使用 libfdk_aac 编解码器从 MKV 到 MP4 的 FFMPEG 转换错误

Question

这样做的目的是因为我的“智能”三星电视不播放 MKV 文件。

This thread提到不需要视频转换，只需更改容器就足够了。在阅读了有关如何将 MKV 的容器更改为 MP4 的多个线程之后，我从 here 下载并编译了带有 libfdk_aac 支持的 FFMPEG .我尝试使用以下命令转换示例 MKV 文件:

ffmpeg -i "C:\VideoTest\Sample1.mkv" -c:v copy -c:a libfdk_aac -b:a 384k "C:\VideoTest\Sample2.mp4"

但出现以下错误(从命令提示符复制):

还尝试使用此命令:

ffmpeg -i input.wav -c:a libfdk_aac -b:a 128k output.mp4

但这会破坏视频质量，并且在播放过程中我开始看到一些糟糕的像素化补丁。

任何帮助，将不胜感激。

仅供引用:我通过阅读博客和帖子走到了这一步。我对视频转换的了解为 0。

Answer 1

如果您在第一个命令后无法播放视频，那么(显然)您的电视无法处理原始编码的视频流。所以 - 尝试使用另一个编解码器重新编码。这将产生一个高质量的重新编码版本(重新编码需要一段时间):

ffmpeg -i input.mkv -qscale 1 -c:a libfdk_aac -b:a 384k output.mp4
