[Libav-user] FFmpeg components needed to extract audio/video metadata

[William Seemann]

Hello!

I'm currently developing an Android application that uses FFmpeg to 
retrieve metadata for core supported audio/video formats (see the 
formats here: 
http://developer.android.com/guide/appendix/media-formats.html). In 
order to keep the APK build size small I was wondering if anyone can 
tell me what components are required to extract metadata? In other 
words, what flags are needed at compile time to extract metadata. I'm 
currently using the following flags (which work) but I know they could 
be more granular:

     FLAGS="$FLAGS --enable-shared --disable-symver"
     FLAGS="$FLAGS --enable-small --optimization-flags=-O2"
     FLAGS="$FLAGS --disable-doc"
     FLAGS="$FLAGS --disable-ffmpeg"
     FLAGS="$FLAGS --disable-ffplay"
     FLAGS="$FLAGS --disable-ffprobe"
     FLAGS="$FLAGS --disable-ffserver"
     FLAGS="$FLAGS --disable-avdevice"
     FLAGS="$FLAGS --disable-swresample"
     FLAGS="$FLAGS --disable-swscale"
     FLAGS="$FLAGS --disable-postproc"
     FLAGS="$FLAGS --disable-avfilter"
     FLAGS="$FLAGS --disable-everything"
     FLAGS="$FLAGS --disable-gpl"
     FLAGS="$FLAGS --enable-parsers"
     FLAGS="$FLAGS --enable-protocol=http"
     FLAGS="$FLAGS --enable-demuxers"

For instance, if I only need to extract metadata for mp3, ogg, and flac 
what specifically needs to be enabled? Thanks in advance for any help. -
