| Summary | 0013031: f_aac: m4a tracks created for sync with Sony Players using MediaGo do not work correctly | ||||
| Description | m4a tracks created for sync with Sony Players using MediaGo do not work in MMW and are not imported correctly. Initially I thought that only Format of Album Art is a problem but problem looks deeper. Sample tracks are in ticket. | ||||
| Additional Information | TAD-266-35308 | ||||
| Tags | No tags attached. | ||||
| Fixed in build | |||||
|
|
based on IM talk: "MediaGo tags the file in a strange way, it sometimes uses UTF8 and sometimes UTF16, maybe the decoder does not count with this. At least for title, they tag title in two different atoms, in @nam it is in UTF8 and in titl it is in UTF16 and titl should be UTF8 too" |
|
|
As Analyzed QuickTime plays track. |
|
|
Support for reading UTF16 tags added from build 1779. These tags (e.g. udta.titl) are used in f4v files and were always in UTF8, but MediaGo writes them to M4A and in UTF16BE. We need writing them too and check f_aac_codec plugin for correct playback, as it does not play this file for some reason. |
|
|
Playback fixed as 0013033. |
|
|
As tags like udta.titl are not standard in m4a, decreasing priority of writing changes to them. |
|
|
Based on additional user analysis, it seems to be problem with unsupported sort fields. iTunes and MediaGo use special tags used for sorting (Sort Album, Sort Artist, etc.), and it seems, that the Sony Player needs these sort fields for correct functionality. MediaGo adds these tags during sync, and Sony displays all ok, MediaMonkey does not use them, and it leads to problems. So to fix this, we need to support these sort fields, already track as 0002915. |
