Current observations:

1. Creating pdf files reports an error, nut.texi does not produce output from either texi2 prog. Should be fixed by

    for DOCNAME in `basename -s .html *.html | sed 's/nut//'` ; do
   

2. Using doxygen doc/DOXYfile builds the api docs, I found the current text confusing.

3. After building all these docs, my space usage is far larger than the book's 4.0 values. Giving up for the moment, need to track down which part of the docs is so big.

4. Should we really install .ps files when the .pdf have been created ? Displaying postscript seems to have become uncommon, and they do not solve the problem of overlong lines (faq.pdf, faq.ps).

Replying to ken@…:

I think omitting the .ps files would be OK. The reason for them would be for output to a printer, but we have utilities to output .pdf files just as easily. Another reason for .ps files is that they are ascii and can be directly edited with a text editor.

Again, if it's not too much trouble, go ahead and omit them.

I tested it with the old fdk-aac which was in the book at the time I built this. Tim has offered a patch needed to build current ffmpeg-4.0.2 with the latest fdk-aac. I assume that will also be needed for this version, but I no-longer have time to rebuild it, test that my usage of fdk aac works (scripted manipulation of clips from my camera), and remeasure the build and creation of docs.

Giving the ticket back.

The ABI stayed stable, so no recompile are needed. (mpv needs recompile, but is not in the book)
