[FFmpeg-user] essence MD5

[Ganesh.Irelan at syda.org]

Hello,

Non-developer here...

I want to generate an essence MD5 for WAV files and then populate that value into a field in a DAM system.  I have tested two commands to generate the essence MD5 hash.

ffmpeg -i INPUT -map 0:a -f md5 OUTPUT.md5
ffmpeg -i "INPUT" -map 0:a -f md5 -hash md5 -

Neither of these is ideal.  The first one puts the value in a separate file.  The second puts it amongst other info in the console making it difficult to parse out as in the following example.  (The value I want is the fourth line from the bottom.)  Is there an FFMPEG command that will give a cleaner console output than this?

Thank you,
Kevin
