Description (Last modified by gbooker)

Hi, I've tried a number of MKV files with dd51.x.264, ac3.5.1.x264, etc. and none of them has worked with quicktime 7.3.0 and OSX Tiger 10.5 (9A581). In the following torrent the first 3 files only play the first 5 seconds, and number 4 and 5 freeze quicktime. All work fine in mplayer or vlc.

Also none of the MKV files I've tried are recognized as playable by quicktime, although when I use "open with" I can specify quicktime and it notes that matrojska files are playable with quicktime.

  • description changed.
  • summary changed from FLV Files Playing either only first 5 seconds, freezing completely, or static bursts in audio to MKV Files Playing either only first 5 seconds, freezing completely, or static bursts in audio.

These are all MKV files, not FLV files; there is a big difference. I corrected the description.

Absolutely no issue here at all. Do you have that old AC3Codec component installed? If so, trash it; that's the problem. Otherwise, list all the Quicktime Codecs you have in /Library/QuickTime as well as ~/Library/QuickTime

I am also getting those static bursts in the audio when I play MKV files. I have the following components in my Library/Quicktime folder: 1) AC3MovieImport.component 2) AppleIntermediateCodec?.component 3) AppleMPEG2Codec 4) Perian.component I tried taking the AC3MovieImport.component out and trashing it (restarting quicktime), but the sound artifacts were left unchanged. Any idea what is going on here? Thanks for the help!

I am running 10.5.1, core2 duo, Quicktime 7.4 and perian 1.0

This issue is still present. MKV plays fine for 5 seconds then loud static bursts for the remainder of the movie. VLC doesn't seem troubled by it so I think the file is fine. Let me know if you want help testing.

I get the same issue with MKV files I've tried to play in QuickTime Player. Interestingly, they play much better in Front Row. (Still maybe not as good as with VLC, but no loud bursts of static like in QT Player.) It makes me wonder what the issue really is? QuickTime Player plays the MKV with these horribly loud bursts of static every few seconds, whether I'm viewing the movie in a window or full-screen. But as soon as I switch over to Front Row, the audio sounds fine.

[Update] Before posting this, I was listing out all the (many) QuickTime components I had installed. Most of them are from Apple (AppleIntermediateCodec?, MPEG2Codec, DVCPROHD*, FCP Uncompressed, etc.) and Flip4Mac. But there were several crusty old ones in /Library/QuickTime from DivX, XVID, 3ivx, and ogg. Getting rid of the DivX/XVID/3ivx ones didn't change the situation. But getting rid of the ogg ones (oggvorbis.qtx, oggimport.component, theora.component) seems to have cleared up the problem completely now. I don't get the static at all, either in QuickTime Player or in Front Row.

I still think it was weird that I would get static bursts in Quicktime but not in Front Row. But now (without the ancient ogg stuff) I don't get audio problems at all, and that's of course the best. Anyway, I hope this is helpful to someone.

Thanks for the update, but I still have issues.

In QT and Front Row, there is no audio anymore, only loud static pops that never stop unless I stop the movie. I have the passthrough hack set and perian 1.1 and qt 7.4.1 and os 10.5.1

Any direction with this would be appreciated. I have an mkv file with ac3 5.1 audio at 48,000hz
