Background: Video usability information (VUI) is extra information that can be inserted into an AVC (h.264) or HEVC (h.265) video bitstream. The documents defining AVC and HEVC specify that an AVC/HEVC-decoder retrieves this information. Reference software of AVC and HEVC en- and decoders can be found here [1], [2].
My question: Where is VUI stored after AVC/HEVC-decoding? Is it stored within the output file *.yuv?
I am very grateful for any advice.

I investigated the AVC [1] and HEVC [2] reference software, but I after decoding VUI from the bitstream, I loose track what happens to VUI.
YUV is a raw pixel format. Meaning that there is absolutely no information other than the pixels' intensity values in it.
If you want your VUI data:
Pre-save the FPS elsewhere and/or use a custom delay (FPS) during the decoding process.
Write your YUV data into a formats that supports timing info (eg: .y4m format).
