  • error: ‘x264_bit_depth’ undeclared (first use in this function)

    When installing ffmpeg, i get error

    CC	libavcodec/libvorbisenc.o
CC	libavcodec/libx264.o
libavcodec/libx264.c: In function ‘X264_frame’:

    This is due to incompatability with ffmpeg and x264.

    What you can do is try another version of x264. You will be able to download older version of x264 from

    ftp://ftp.videolan.org/pub/x264/snapshots

    On 2018-08-14, it failed with latest stable snapshot. So i tried 14 days old stable snapshot

    cd /usr/local/src/
wget ftp://ftp.videolan.org/pub/x264/snapshots/x264-snapshot-20180730-2245-stable.tar.bz2
tar xvf x264-snapshot-20180730-2245-stable.tar.bz2
cd /usr/local/src/x264-snapshot-20180730-2245-stable
make clean && make distclean
./configure --prefix=/usr --enable-shared
make && make install
ldconfig

    This worked with ffmpeg.

    Solution here is to try latet version first, if it did not work, try older version, say try 1 month old version, if that did not work, go back 2 months, see if that works.

    Now install ffmpeg with

    cd /usr/local/src/
wget https://github.com/FFmpeg/FFmpeg/archive/n3.3.5.tar.gz
tar zxf n3.3.5.tar.gz
cd /usr/local/src/FFmpeg-n3.3.5/
ldconfig
make clean && make distclean
./configure --prefix=/usr --enable-shared --enable-libxvid --enable-libvorbis --enable-libtheora --enable-libmp3lame --enable-gpl --enable-libfdk-aac --enable-nonfree --enable-libx264 --enable-libfreetype
make && make install && ldconfig
