|Analyzed by developer:||no|
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
- Keywords mp4 muxer metadata added
- Owner changed from michael to baptiste
- Status changed from new to open
- Component changed from FFmpeg to avformat
