The field was a normal public and documented field
Documented in our public doxygen for 3.0 and 3.1
http://ffmpeg.org/doxygen/3.0/structAVFrame.html#a0452833e3ab6ddd7acbf82817a7818a4
http://ffmpeg.org/doxygen/3.1/structAVFrame.html#a0452833e3ab6ddd7acbf82817a7818a4

The AVFrame.pts doxy links to examples, which use the field:

http://ffmpeg.org/doxygen/3.1/demuxing_decoding_8c-example.html#a41
