问题描述
我正在尝试在Ubuntu 18.04.5和macOS Mojave 10.14.6上构建从git源下载的ffmpeg 4.3示例编。所有都在两个系统上正确构建。编译的编在MacOS上工作，但在Ubuntu上失败。例如：
在Ubuntu上，当我运行具有非常基本信息的 muxing 程序时，我会得到：
dev@boots:~/code/new_ffmpeg/FFmpeg-master/doc/examples$ ./muxing test.mp4
[mpeg4 @ 0x5626024f8b40] [IMGUTILS @ 0x7ffdd2893080] Picture size 0x0 is invalid
[mpeg4 @ 0x5626024f8b40] Ignoring invalid width/height values
[mpeg4 @ 0x5626024f8b40] [IMGUTILS @ 0x7ffdd2893060] Picture size 0x0 is invalid
[mpeg4 @ 0x5626024f8b40] The encoder timebase is not set.
Could not open video codec: Invalid argument
dev@boots:~/code/new_ffmpeg/FFmpeg-master/doc/examples$
但是当我在macOS上运行相同命令时，我得到了：
Kinley:examples CC15$ ./muxing test.mp4

为什么它不能在Ubuntu 18.04.5上运行而不能在Mac上运行？
文件test1.mp4是一个已知的好文件，其他编组（例如VLC）可以在两个系统上正确播放。
任何人都可以提供关于我做错了什么的建议吗？
