不支持DVCPRO HD编码的ffmpeg错误

问题描述

请帮助，我正在尝试对视频流进行编码，并使用与输入相同的格式输出视频：

ffmpeg -i input.mov -c:v dvvideo -pix_fmt yuv422p -b:v 115084915 -maxrate 115084915 -minrate 115084915 -r 29.97 -top 1 -color_primaries bt709 -color_trc bt709 -colorspace bt709 -vtag dvh6 -c:a copy -c:s copy -y output.mov

这是输出：

DVCPRO HD encoding is not supported.\n[dvvideo @ 0x7ffaee815c00] ff_frame_thread_encoder_init failed\nError initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate,rate,width or height\nConversion failed!\n"

解决方法

您使用的是ffmpeg的旧版本。

在最新版本中，DV编码器支持以下组合：
