我正在使用 ffmpeg 将帧列表收集到视频中。我以前在这方面取得了很大的成功，但现在执行命令时遇到错误ffmpeg -i %d.jpg -c:v huffyuv test.avi：

[swscaler @ 0x7f627174a2c0] deprecated pixel format used, make sure you did set range correctly
[huffyuv @ 0x7f62717821c0] Width must be even for this colorspace.
[huffyuv @ 0x7f627173b5e0] ff_frame_thread_encoder_init failed
Stream mapping:
Stream #0:0 -> #0:0 (mjpeg (native) -> huffyuv (native))
Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
我注意到错误消息包含Width must be even for this colorspace.我不确定这实际上意味着什么，所有框架都有相同的尺寸
答案1
但我不确定这到底意味着什么
上面写的1537是奇数。你可以裁剪掉一列像素。
ffmpeg -i %d.jpg -vf crop=1536:673:0:0 -c:v huffyuv test.avi
这里删除了最右边的像素列。将裁剪中的第三个值更改为1删除最左边的列。为了避免裁剪，您必须将视频保存为 RGB。
ffmpeg -i %d.jpg -pix_fmt rgb24 -c:v huffyuv test.avi
但这无助于提高你的压缩效率。
