How is your remote desktop software? Are there any SCC streams for testing?
Image sequence coding is currently not supported at all and there are also no plans to work on it until someone can convince me that this is useful for anything...
I'm still not sure what you are actually showing, because libheif cannot produce sequences. It can produce files with multiple images, but these are not sequences (HEIF standard section 7...
@silverbacknet It's also the same codec. Whether you put h265 or av1 into a HEIF container or an MP4 container does not matter at all.
"Lossless" refers to the HEVC compression settings. When you are encoding from a PNG, there is a color-space conversion involved. PNGs are stored in RGB color-space, while HEIF is in...
Yes, this is definitely the way to go. However, I am still unsure how to correctly indicate the colour space of the image data. Strangely, I didn't see anything about...
A warning is now printed when an RGB input image is compressed to YUV in lossless mode (6bd1a7e).
I'm still trying to figure out how RGB images might be stored in an HEIF image. Now, I found that one could set the `matrix_coefficients` in the color profile to...
Yes, HEVC supports `GBR`, but it also does not mandatorily indicate that this color space is used. There is a field `matrix_coefficients` in the VUI header, which can be set...
@dbtsai: I'll check our colorspace conversions. Maybe there are some rounding errors that lead to the higher distortion. Those lossless YUV conversions are not supported in the HEIF standard (yet)....
