What's new in QMedia 1.2.6
Bug fixes:
- 4D 2003.2 changed the way it draws plug-in areas and this caused
update problems in the movie plug-in area. Fixed.
- Identified and corrected a potential issue where the developer license would
not be copied to the compiled structure when building
compiled or standalone applications with 4D 2003.x.
- Restored compatibility with Win NT/SP6a.
- Long path names are now supported on Win NT.
- It was possible to crash on 4D Server when a client was logging out
if at that time the licenses dialog was open. Fixed.
Known issues:
- The QTVR problem is still there (see "Known issues" below). 4D
egnineers are still aware of the issue, but no fix has been released as
of 4D 2003.2.
What's new in QMedia 1.2.5
Bug fixes:
- When inserting a track segment with
QM_InsertTrackSegment using a reference instead of copying the
media samples, QMedia could fail to set the media timescale of the destination
track correctly. This affected mostly audio tracks, where the destination
track would produce noise or fail to play at all. Fixed.
- Recording sound from DV cameras on MacOS X could fail with
error -200 (not enough hardware). Fixed.
- It was not possible to open movies that had their movie atom stored
in the resource fork instead of the data fork. Fixed.
- Fixed a bug where the plug-in could crash after switching to another data
file with OPEN DATAFILE or CREATE DATAFILE. MacOS X only.
- Under rare circumstances the plug-in could fail to load expansion
licenses on Windows. Fixed.
Known issues:
- The QTVR problem is still there (see "Known issues" below). 4D
egnineers are still aware of the issue, but no fix has been released as
of 4D 2003.1.
What's new in QMedia 1.2.4
New features:
- Added the QM_SetMaxGrabberOutputSize and QM_GetMaxGrabberOutputSize
commands that control the maximum file size of the grabbed movie.
Bug fixes:
- QM_Play(areaRef;0) would not stop a playing movie. Fixed.
- QM_GetSelection would always return error 1. Fixed.
- On MacOSX the qm_GoToTimeEvent can be triggered by QuickTime
outside of a valid 4D context. This could cause "no stack memory" 4D
errors. The callback method is now called only when the qm_GoToTimeEvent event is
triggered in the context of the correct 4D process.
- On MacOS X QMedia would fail to resolve a pathname if the name of the disk contained a
slash character ("/"). Fixed.
- In a rare case licenses installed when running under 4D Server
would not be saved. Fixed.
- Under certain circumstances QMedia could cause long delays during
application startup. Fixed.
Known issues:
- The QTVR problem is still there (see "Known issues" below). 4D
egnineers are still aware of the issue, but no fix has been released as
of 6.8.3.
What's new in QMedia 1.2.3
Bug fixes:
- When running under 4D Server on MacOS X an error dialog reporting
"no stack memory" would pop up continuously. Fixed.
- Under certain circumstances it was possible to loose installed licenses
when running under 4D Server on Windows. Fixed.
- Under certain circumstances the file selection dialog would not accept
mouse clicks when running the PPC version of the plug-in on MacOS 9. Fixed.
Known issues:
- The QTVR problem is still there (see "Known issues" below). 4D
egnineers are still aware of the issue, but no fix has been released as
of 6.8.3.
What's new in QMedia 1.2.2
Bug fixes:
- There were errors in the documentation for the QM_TestMovieFile command.
The command docs have been updated to correct these errors.
- The QM_SetMovieAnnotation command was not working properly. Fixed. Mac/Win.
- When using the classic PPC version of the plug-in with 4D 6.8.x
under Mac OS 8/9, there were problems with movie display in the plug-in
area. Fixed. Mac only.
- When calling a plug-in command on Windows without QT installed,
QMedia might crash due to a bad check for QuickTime's presence. Fixed.
Win only.
- The product name returned by the QM_GetVersion command now shows
whether the plugin is Carbon-based or not. For example, the Carbon
version of the plug-in will return "[plug-in name] [version] Carbon",
and the corresponding PPC version will return "[plug-in name] [version]
PPC". Mac only.
- On some localized systems (Russian, Japanese) 4D would present a
syntax error dialog during plug-in initialization and the plug-in would
fail to display the license registration dialogs. Fixed. Mac/Win.
- If 4D Client attempted to call a plug-in command when no license
seats were available on the server, the plug-in would block program
execution instead of faling back into demo mode. This is now fixed; the
plug-in will run in demo mode as expected. Mac/Win.
Known issues:
- The QTVR problem is still there (see "Known issues" below). 4D
egnineers are still aware of the issue, but no fix has been released as
of 6.8.3.
What's new in QMedia 1.2.1
Bug fixes:
- Fixed a potential crash during startup when running with 4D 6.7.x.
- Fixed a bug that could cause long delays during startup when
running with 4D Client on Windows.
- Fixed a problem where the "Escape" menu would become unresponsive
when running with 4D Server 6.8.x on Windows.
Known issues:
- After much investigation we have identified the cause of the QTVR
problem (see "Known issues" below). The problem is not in QMedia or
QuickTime, but in 4D. The egnineers at 4D are aware of the issue, and
hopefully there will be a fix in a future update of 4D 6.8.x.
What's new in QMedia 1.2
New features:
- Carbon version runs natively on MacOSX
- Revamped import/export dialogs using Navigation Services on
MacOSX/MacOS
- New license control system
Bug fixes:
- Fixed a random crash in the sequence grabber under MacOS 9.x.
Known issues:
- There is currently a problem playing QuickTime VR movies under
MacOS X. QuickTime complains that memory is low and displays a broken
movie icon. This does not seem to be a QMedia issue (we have reproduced
the problem outside QMedia). It seems to be some obscure anomaly or
incompatibility between QuickTime and 4D. We will keep investigating
this issue; as soon as we come up with a workaround or fix, we will
release an update.
