Hi,
“I am trying to generate a minimal ffmpeg build with support for just some
of audio/video decoders (like AVC, HEVC, AAC-LATM, AAC, & AC-3). In order
to do so, I am trimming down the ffmpeg dependencies via the following
representative configuration options:
*./configure* *\*
*--disable-debug* *\*
*--disable-doc* *\*
*--disable-ffplay* *\*
*--enable-shared* *\*
*--enable-avresample* *\*
*--enable-gpl* *\*
*--enable-libmp3lame* *\*
*--enable-libvpx* *\*
*--enable-libwebp* *\*
*--enable-libxvid* *\*
*--enable-libx264* *\*
*--enable-nonfree* *\*
*--enable-openssl* *\*
*--enable-libfdk_aac* *\*
*--enable-postproc* *\*
*--enable-small* *\*
*--enable-version3* *\*
*--enable-libzmq* *\*
*--extra-libs=-ldl* *\*
*--prefix=**"**${PREFIX}**"* *\*
*--enable-libopenjpeg* *\*
*--extra-libs=-lpthread* *\*
The specific ffmpeg libraries I want to link my application against, are
*“-lavcodec -lavdevice -lavfilter -lavformat -lavutil -lavresample -lm
-lpthread -lswscale -lstdc++*
*”*. However, in this configuration I observe that a call to
*av_parser_init()* fails to return a parser for any of the codec IDs like
AVC or AAC.
A call to *avcodec_find_decoder()* with an AVC or AAC codec ID however,
seems to work fine.
Is there a dependency on any other library like *“freetype”* etc. that I
need to enable in my configuration above, in order for *av_parser_init*()
to succeed?
Thanks in advance!
