codec info bugs and missing data

[Omertron]

Original issue 2025 created by Omertron on 2011-07-03T07:00:32.000Z:

Mediainfo needs to be completely revisited. The way data is saved is not a full picture of the format being used. In some case it could mean any of a dozen different variations.. codec_id is not enough..

Examples:

• microsoft appears as a lot of codecs. Are these vc-1, wma, wma pro, ms mpeg-4? etc
• A_DTS, is this DTS, DTS-ES, DTS-9624, DTS-MA, etc etc.
• A_AC-3, Is this DD, Real AC3, AC3 CM?

This is one of those variations that would probably break existing so many 2 new codec fields with more info might be better to add.

From what I've pieced together, these are the fields that matter to figure things out. If they were predictable like field1|field2 : next channel field info that would be great.

Note some of the fields have / in them so the current / would be bad.

Video fields:
Format
Codec ID
Codec ID/Hint

Audio fields:
Format
Format Version
Format profile
codec id (not hint)

This will also be helpful when new hardware not sigma comes out.

Forgot to add: you can find a good reasonable sized test package to run mediainfo against at: http://community.mediabrowser.tv/permalinks/3293/mediatype-sample-videos-set

Some fields do not appear when they aren't part of the codec.

The new format will be:
{{{


AC3
AC3+



}}}

The old format will be kept for backward compatibility.

Will this have any impact on the overlay codec?

Hopefully, no. However, it would be nice for overlay to use the new values so that they are more accurate
