Cannot install snappy with brew - fatal error: 'cassert' file not found

Question

I am on an old mac - 10.14.6 - and I am trying to install ffmpeg via brew.

I am finding errors during the make of snappy

When I try to brew install snappy the same errors persist:

==> Installing dependencies for snzip: snappy
==> Installing snzip dependency: snappy
==> Patching
==> cmake . -DSNAPPY_BUILD_TESTS=OFF -DSNAPPY_BUILD_BENCHMARKS=OFF
==> make install

Answer 1

In case anyone else has as old of a mac as I do and cannot install ffmpeg via brew, then the work around that I found was to download and extract the zip of ffmpeg and place it in the same directory/folder as the file that I wanted to run the command line:

Download ffmpeg zip

Once I downloaded and extracted the zip, I moved ffmpeg in the same directory, followed by running the following command:

./ffmpeg -i Not-if.mov -c:v libx265 -vtag hvc1 -c:a copy not-if-hevc.mp4

This is a one hour, twenty seven minutes, thirty two second and one frame file, so it will take a while for it to complete the task for me to verify if it worked, but for now, it is displaying stats in the terminal with every frame processed, so I believe it is working.

BTW, I have spent most of the day trying to get this going and I just finished a graveyard shift and I am working a graveyard shift tonight. I really should be sleeping right now. I went away from software development to get away from such a sleep deprived lifestyle, but if the notification on the screen shows "HDR" when the UHD dvd is playing, then this will have been so worth it.
