What is the input for JM reference software?

[koliva]

Hello all,

In the JM software manual, it says for InputFile,


InputFile
Specifies the filename (without the .yuv) of the original raw video sequence to be encoded.

I have a jpg image sequence from a movie. I can convert them to Yuv format. Let say I want IBBBP configuration. Do I need to create a new yuv video for all image sequence? Is there any other way to put these images into the encoder? Does it have to be a yuv video?

Thanks a lot.

JPEG's won't work. You need uncompressed YUV videos, similar to those "YUV samples" you find here:

Then, the question is how I can convert my image sequence to YUV video? I can generate frames as uncompressed images but not yuv file.

ffmpeg -i input -pix_fmt yuv420p -f rawvideo output

I have read the "how to" document and I think I can't combine my images from image sequence by using ffmeg. It only converts from one type of video to another. I need something like AVS script but there, I can't save my video file as yuv file.
do you have any suggestions?

ffmpeg -f image2 -i name%03d.jpg ...

will read name000.jpg, name001.jpg, etc.

You can use the AviSynth plugin Immaavs to convert your script to a yuv file.
