| Summary | 0007226: Devices using WMDM can't be ejected (aka General Format plugin is unstable) | ||||
| Description | During testing of 0007213 I found one problem. If I plug-in a common USB stick (e.g. flash memory) and start MediaMonkey then its content is scanned, but even if the scanning is complete it is impossible to eject the device until MediaMonkey is closed | ||||

I have debugged the issue and it is caused by tag reading from MOV files. MOV files are locked by MM until MM is closed The MOVs also cannot be deleted until MM is closed. The same issue appears if MM just read tag from a MOV that is placed anywhere, the file is locked until MM is closed. Sample MOV file is attached on FTP. |

Fixed in build 1346. In consequence of this, file formats, which does not have format plugin, will have unknown video length and size. This should be fixed by other format plugins in the future (MOV, MPEG1/2, FLV, OGV). This solution will be also noticeably faster and safer. |

Additional notes for testers: The fix to this bug was to replace the general format plugin, which relied on DirectShow to determine video file length / frame size, with custom format plugins per container type: AAC plugin - MP4, M4V and MOV (not all kinds of MOV yet) f_AVI - AVI, DIVX, XVID f_MKV - MKV f_WMV - WMV, WM, ASF In addition, format plugins will be created for other content types based on the following order (by priority): MPEG-PS, MPEG-TS containers for MPEG1/2 (0007317) MOV, QT (complete support--some types are still unsupported) FLV, F4V (0007291, 0007326) DVD (0006967) WebM (VP8 is video codec) (0007353) 3GP, 3GPP (may already be covered by AAC plugin) Finally, for OGV/OGM, and RM, and other formats for which a Format plugin doesn't exist, use general DirectShow plugin (0007355) Re-set to resolved, since I'm not sure if testing covered for possible regressions in relation to the functionality described above. |
