How to save from JPG/JPEG/PNG to HEIC format #11

Open kingvhit opened 4 years ago

kingvhit commented 4 years ago

Thank you very much for your contributions on HEIF Utility lib, I have ported it on Android library and then convert between HEIC to JPG/JPEG is so easy.

Now, I want to convert from JPG/JPEG to HEIC, but I don't know how can separate the decoder config and image data from an image (jpg, jpeg files) as byte[] data.

Did you know, how I can do it, because the document is very difficult for understanding in Java code, and I think the C/C++ is better for trying.

Hello Sir

I believe you should choose a certain Image library first... And then we can talk about how to use those API to do that...

I'm using FFMPEG for converting from .265 bitstream into 48 tiles files on storage in case HEIC -> JPG/JPEg but it's a command-line executing and we can't get the byte[] array in code. I just do convert bit-stream to file and read its file again then get the byte[]

Do you have any idea for other libraries? C/C++ libraries are OK for me because I will port it into a native library and call .so file instead.
