[Bug 327872] Re: Broken support for AVCHD (MTS/M2TS)
Jean-François Fortin Tam: AVCHD is about H.264 codec but the codec output is stored inside an MPEG transport stream and stored on media as binary files (as explained on the wikipedia page you linked to). See http://en.wikipedia.org/wiki/AVCHD#Specifications for details, notice especially the part Stream type: MPEG transport stream. A camcorder that stores the H.264 codec output in a .mov container is not AVCHD conforming, if I've understood correctly. H.264 codec works already fine with gstreamer, the problem is M2TS (or .MTS in 8.3 file system) container format used to store the H.264 codec output. VLC is already able to play H.264 stored inside M2TS container modulo some bugs (such as not being able to correctly skip in the middle of the file). -- Broken support for AVCHD (MTS/M2TS) https://bugs.launchpad.net/bugs/327872 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gstreamer0.10 in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

Jean-François Fortin Tam: You're right that HDV is a different format from AVCHD. On the other hand, the letters HDV in the summary seems to be short for high definition video contrary to HDV format which officially does not have an explanation for the letters. I agree that the use of letters HDV in this context is ambiguous and the summary could do better without it. -- Broken support for AVCHD (MTS/M2TS) https://bugs.launchpad.net/bugs/327872 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gstreamer0.10 in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

[Bug 327872] Re: Broken support for AVCHD (MTS/M2TS)
The title and description of this bug is, from what I can tell, wrong. AVCHD is *not* MPEG-2 TS, and certainly not HDV. Take a look at http://en.wikipedia.org/wiki/AVCHD ; it's all H.264 AVC there. Thus the current bug report should be about MPEG-2 Transport Stream camcorders, because actual *AVCHD* camcorders (at least mine, which does H.264 in a .mov container) do not cause any problems and work fine with PiTiVi. -- Broken support for AVCHD (MTS/M2TS) https://bugs.launchpad.net/bugs/327872 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gstreamer0.10 in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

[Bug 327872] Re: Broken support for AVCHD (MTS/M2TS)
Thank you for bringing this bug to our attention. However, a paper cut should be a small usability issue , in the default Ubuntu 9.10 install , that affects many people and is quick and easy to fix. So this bug can't be addressed as part of the project. For further info about papercuts criteria , pls read https://wiki.ubuntu.com/PaperCut Don't worry though, This bug has been marked as invalid ONLY in the papercuts project. ** Changed in: hundredpapercuts Status: New = Invalid -- Broken support for AVCHD (MTS/M2TS) https://bugs.launchpad.net/bugs/327872 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gstreamer0.10 in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
