FFmpeg：ffv1编解码器的图像序列？

Question

是否可以使用ffv1编解码器在ffmpeg中输出图像序列？

如果是这样，在什么容器中，我如何将这些重新导入ffmpeg？

• 电影容器似乎不可能用于seq输出
• 我可以强制输出-f image2到任何容器，但即使使用 -c：v ffv1 作为输入选项也无法导入。

编码＆＃34; intermediate.ffv1＆＃34;

ffmpeg -y -ss 250 -i "/media/pool/vrender_input/movie.mov" -vframes 1 -c:v ffv1 -compression_level none -map 0:0 -an -f image2 -threads 0 "/media/scratch/intermediate.ffv1"    

解码＆＃34; intermediate.ffv1＆＃34;

ffmpeg -y -c:v ffv1 -f image2 -i "/media/scratch/intermediate.ffv1" -c:v tiff -an -f image2 "/media/scratch/final.tif"

错误：

怎么了？

谢谢！
