我有一堆 MP4 是从无法播放的 Android 手机上取下来的。从各方面来看，它们“看起来”很好，但显然存在问题。我试过用 Handbrake、Avidemux 和 FFMPEG 转换它们，但没有成功。我相信这些视频缺少像素格式，但我不确定。
我用 -pix_fmt 、 -analyzeduration 和 -probsize 尝试了各种 ffmpeg 命令，但似乎没有任何效果。
下面是一个问题文件上的 ffprobe 命令的屏幕截图。
欢迎任何和所有建议。
提前谢谢。
当我尝试使用 ffprobe 查看文件详细信息时，我得到以下信息:

最佳答案
“未指定的像素格式”是结果，而不是原因。它无法识别 pixfmt，因为它无法解析 SPS在 H.264 数据流之外，它不能这样做，因为文件太损坏，无法读取帧并找到任何实际的视频数据包(如所有“无效的 NAL 单元大小”所示)。您不会使用任何传统工具来解决此问题，而且可能根本不会。
关于ffmpeg - FFPROBE - "Unspecified pixel format"，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/71151788/
