FFmpeg created a 10 bit y4m here, which mjpegtools doesn't support. I'll amend the example, but you can force the output to 8 bit by adding -pix_fmt yuv420p
to the FFmpeg arguments (this source is 4:2:2, but only the Y plane is used, so the chroma subsampling is harmless.)
If you have an example of a png that doesn't work with the libpng reader I can take a look at what's going wrong there. I should probably change the default to only use libpng/libjpeg when ImageMagick isn't available, although I'd like them to be reliable fallbacks.
here is link to png https://send.firefox.com/download/6036d14ade/#8pC6tq-eiYUXqShIFzvw6A
and thanks! that change worked! it detected the upscaled vid. (at least on my 1 test case :D ) so thats a good start.
Thanks -- I hadn't been setting filters to convert 16 bit pngs correctly (this came up with alpha also but I didn't realize the root of the issue). It's fixed now, but since you're already using it with ImageMagick instead there's not much point in updating.
great.
Hi. Trying to use with a y4m. Generated one as per example in readme, but when i point resdet at it i get Invalid Image. image.y4m.zip
I've tried building a few different ways. Once i built with
it would then recognize png files (otherwise, it was giving invalid image for pngs too)
Let me know what other info I can provide.
