enable the "vorbis_parser.h" in ffmpeg build

Question

ffmpeg build configuration is such that I have disabled everything and selectively enabled decoders and encoders and demuxers for the formats that I need. I want to use the vorbis_parser.h for parsing the extradata, I tried using the --enable-parser=vorbis but this does not work. In the include folder of libavcodec there shows no file named vorbis_parser.h. What option should I set so that I can use vorbis_parser.h

Answer 1

I realized that the functions beginning with avpriv are the private functions of the FFmpeg and those are not included in the header files that are exposed. So probably we cannot include the file vorbis_parser.h

Answer 2

As far as i know, the ./configure script for ffmpeg looks like this :

./configure --prefix="$HOME/ffmpeg_build" \
--extra-cflags="-I$HOME/ffmpeg_build/include" --extra-ldflags="-L$HOME/ffmpeg_build/lib" \
--bindir="$HOME/bin" --extra-libs="-ldl" --enable-gpl --enable-libass --enable-libfdk-aac \
--enable-libmp3lame --enable-libopus --enable-libtheora --enable-libvorbis --enable-libvpx \
--enable-libx264 --enable-nonfree --enable-x11grab

To me it seems like you just have to --enable-gpl and --enable-libvorbis in your ./configure script.

Nevertheless there may be options to be enabled and disabled in the libvorbis ./configure script. I hope this may help.

Have a nice day ;)
