 ffmepg binary was downloaded from
 http://ffmpeg.arrozcru.org/autobuilds/ffmpeg/mingw32/static/ffmpeg-r26400-swscale-r32676-mingw32-static.7z

 executed ffmpeg -i 1.flv -f mp4 -metadata lyrics="abc" 1.mp4 to embed
 lyrics meta data to mp4 container format video file

 from  http://wiki.multimedia.cx/index.php?title=FFmpeg_Metadata, it seems
 lyrics metadata was supported by mp4 container.

 but after conversion ,
 execute ffmpeg -i 1.mp4 lyrics metadata was not displayed .

 use a hex editor to edit the mp4 file , I can find "abc" text was appended
 at the end of mp4 file.

 But it seems  av_metadata_get did not read the lyrics metadata correctly.
 some other metadata seems ok for example title meta tag.

 >>ffmpeg -i 1.flv -f mp4 -metadata title="abc" 1.mp4
