Title: MP4-Import problems
Post by: Mirko on December 15, 2006, 01:00:39 am
Hi,

yesterday I would have liked to synch my new iPod G5 (I think so... the newest one) with a lot of MP4-Videos I just encoded (Charmed season 5 and 6). To synch I had to import all the MP4-Videos into the database. For about 95% of the videos this was no problem, but 3 or 4 of the mp4s couldn't be imported and I got an error message during "GetInfo" (or similar).

Because the mp4s are quite large (about 150MB each) I can't email them to support I think ;) Is there anything I can do to help you resolve this issue?

Mirko

btw. the synch of about 1.000 pictures and 40GB of music was no problem

Just to check... Those videos do play properly with Quicktime Player, correct?  It's possible that you have a bad, or non-Quicktime compliant, encode on that handful.  iPods will only handle Quicktime compatible MPEG-4 (which isn't all of them because Quicktime only supports a subset of the profiles in the MPEG-4, Part 10 spec).

Also, if you use Windows Media Player, do they play?

Can you manually play them in MC by doing File --> Open and browsing and finding them?

Hi Glynor,

I did another test yesterday. Imported them into iTunes on the Mac - and they played and transfered perfectly.

I don't really know if they would play in Quicktime, because I can't get quicktime to install on my vista 64bit-system. The other mp4-files were imported succesfully, so I would like this has nothing to do with installed or not installed quicktime... maybe I'm wrong with that one...

Okay.  That works.

Vista 64-bit is important info.  But this helps...

What about the other questions?  Does MC play them?  Does WiMP?

I just checked again. No. MC doesn't play them (but it plays some of them). WiMP doesn't play any of them (I guess missing decoder for WMP). VLC does play all of them.
Hm. Sorry I can't find any logfile to provide... they are all encoded using "PQ DVD to iPOD" with the same bit- and framerate. I installed quicktime-alternative (the "original" quicktime7 is not compatible with my vista) yesterday.

Meanwhile I got them imported into MC (but some are not playing) and synced to the iPod. They play fine on the iPod (G5). I cleaned/deleted the library, maybe this was the way to get them imported...

Btw. it's Vista 64bit Release not beta (technet-subscriber).

Because you don't have Quicktime installed, you need an appropriate DirectShow Splitter and decoder filter to be installed before MC can read them.  I'm actually surprised that MC can read any of them at all if WiMP can't (and QT isn't installed).

I don't really know what to suggest to use for Vista 64-bit, but you could certainly try any of these three options:



OR...



OR...



For FFDSHOW I'd grab Celtic Druid's latest build.  For Haali, just do a Google and grab the latest version.  For MP4Splitter.ax, check at Sourceforge.  Sorry no links...

As I said... I'm a bit inebriated.  This should fix you up though.  Also make sure to enable MP4 via DirectShow in MC via Tools --> Options --> Playback --> DirectShow Playback Options --> Check MP4 (or something similar).

Thanks for the help. I think MC can play some MP4-Files because of the installed quicktime-alternative...

I currently downloading MatroskaSplitter and ffdshow celtic for 64bit-Systems. Will report later if this is a solution.

Thanks! This solves the problems I encountered!

Yesterday I discovered another problem related to mp4-playback...

Some episodes from a video-podcast ("angeklickt", a german video-podcast) - the newer ones - did play but didn't show any video. So I tried switching to wimp-playback with no success. After editing the filter and video-render-options I got it to display the video (and play the sound). If I use the Video Renderer 7 or the legacy the video runs perfectly. The legacy renderer switches to the classic color-scheme (the ones without transparency and such). The Video Renderer 7 plays fine - but after two episodes vista crashed and rebootet.

I really don't know if any of this relates to MC - or to vista-drivers and the mp4-filter-things. I'm normally not playing very much mp4-videos. VLC plays them fine but within VLC they look ugly (low contrast and burned highlights...).

Is there anything I can provide to help finding the cause of the problems? I think the whole mp4-filter-thing is partly 64bit and partly 32bit. This doesn't sound too good...

Which video decoder do you use? Try disabling "Hardware Acceleration" on the video decoder if such option is available.

I've read that the 64-bit FFDSHOW you grabbed there from Celtic Druid is horribly buggy (though I have mostly 64-bit capable CPUs I haven't gone 64-bit OS because there's no better performance and because of driver/software issues)...

Have you tried removing that and downloading and running with just one of the 32-bit versions?  You might have better luck there...
