I want encode my mystream.mp4 file in to multiple bit rate.
I recorded this mystream.mp4 from live stream of wowza engine
During live stream we injected some meta data in to stream
e.g.
key: metadataTime
key: metadata
title = Slide------1
TIT2 = Slide------1
key: type
undefined[object Object]
key: metadataTime
key: metadata
title = Slide------2
TIT2 = Slide------2
but when we convert this mystream.mp4 to mystream2.mp4 the resulting mp4 file dose not contain this meta information I think its getting lost in conversion
Could you please check this

Replying to mylostpast:

I looked at the input file mystream.mp4 that you attached: Which metadata does it contain that is not correctly shown by FFmpeg?
comment:3 by , 6 years ago
We injected below metadata/onmetaevent/ontextevent using wowza we are able to view this using jwplayer
key: metadataTime
key: metadata
title = Slide------1
TIT2 = Slide------1
key: type
undefined[object Object]
key: metadataTime
key: metadata
title = Slide------2
TIT2 = Slide------2

We injected below metadata/onmetaevent/ontextevent/timedevent/ID3 using wowza we are able to view this using jwplayer
We are injecting these meta tag after specific interval
key: metadataTime
key: metadata
title = Slide------1
TIT2 = Slide------1
key: type
undefined[object Object]
key: metadataTime
key: metadata
title = Slide------2
TIT2 = Slide------2

If you use hex editor and search for word 'slide' you will get that meta data
I want to convert this video in multibit without loosing this metadata

Please use any editor to edit mystream - new.mp4 file and search for word slide
When we convert this video in multi bit using ffmpeg we loose this meta data

$ md5sum mystream.mp4 47c9fd968696a087b9d7ffec67273d17 mystream.mp4 $ grep -c -i slice mystream.mp4 0
What do I miss?
comment:9 by , 6 years ago
Note you have to search for word slide and not slice
I am not unix programmer but i think you are searching for slice word in file.'
try
$ grep -c -i slide mystream.mp4
