我正在使用 ClipBucket。我已经设置了 ffmpeg，我可以毫无问题地将 AVI、WMV 文件转换为 FLV 视频文件，但现在我正在尝试将 FLV 视频文件转换为具有不同视频质量的 FLV 视频文件。
但是，转换中存在错误。有人能帮助我吗？

最佳答案
[libx264 @ 0x146d900] height not divisible by 2 (648x459)
那是你的错误。通常，在处理任意输入时，您可能希望包含一个强制输出可被 2 整除的缩放器，例如以下，其中高度固定为 460:
scale=trunc(oh*a*2)/2:460
或者你之前解析你的输入文件，看看是否需要重新调整。另见:ffmpeg/avconv force scaled output to be divisible by 2
