使用FFMPEG，如何将框架图像序列转换为视频（视频编解码器：DVVIDEO）？

我正在研究一个图像处理项目。

该项目进行如下：

输入视频 - ＆GT;框架序列 - ＆gt; （处理） - ＆GT;输出视频

我想创建与输入视频相同规格的输出视频。

我们使用的输入视频的规格是：

- Size : 1280x1080, Codec : dvvideo, pixel_fmt : yuv422

但是我正在努力处理以下错误：

Duration: 00:00:03.20, start: 0.000000, bitrate: N/A
    Stream #0:0: Video: png, rgb24(pc), 1280x1080 [SAR 3:2 DAR 16:9], 29.97 fps, 29.97 tbr, 29.97 tbn, 29.97 tbc
Stream mapping:
  Stream #0:0 -> #0:0 (png (native) -> dvvideo (native))
Press [q] to stop, [?] for help
[dvvideo @ 0x55b965b745c0] DVCPRO HD encoding is not supported.
[dvvideo @ 0x55b965451780] ff_frame_thread_encoder_init failed
Error 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
Conversion failed!

代码在下面。（python中的子过程）

ffmpeg -y -f image2 -r "{fps}" -i {input_img_root} -s 1280:1080 -b:v {bit_rate}  -vcodec dvvideo -pix_fmt yuv422p "{output}"

（fps和Bitrate取自输入视频。input_img_root和输出是路径。）

我已经尝试了几天，但是它不起作用。

如果您知道在维护视频规范（尤其是DVVIDEO编解码器）（不使用FFMPEG）的同时制作新视频的任何方法，则可以分享它。

I'm working on an image processing project.

The project proceeds as follows:

Input Video -> frame Sequence -> (Processing) -> Output Video

I want to create the output video with the same specifications as the input video.

The specs of the input video we use are:

- Size : 1280x1080, Codec : dvvideo, pixel_fmt : yuv422

But I am struggling with the following error:

Duration: 00:00:03.20, start: 0.000000, bitrate: N/A
    Stream #0:0: Video: png, rgb24(pc), 1280x1080 [SAR 3:2 DAR 16:9], 29.97 fps, 29.97 tbr, 29.97 tbn, 29.97 tbc
Stream mapping:
  Stream #0:0 -> #0:0 (png (native) -> dvvideo (native))

Error 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
Conversion failed!

The code is below. (subprocess in python)

ffmpeg -y -f image2 -r "{fps}" -i {input_img_root} -s 1280:1080 -b:v {bit_rate}  -vcodec dvvideo -pix_fmt yuv422p "{output}"

(fps and bitrate are taken from the input video. and input_img_root and output are paths.)

I've been trying for several days, but it doesn't work.

If you know any way to make a new video while maintaining the video specifications (Especially dvvideo codec)(not using ffmpeg), it would be nice to share it.
