Ogg vorbis "crashing" sound in MPC 6.4.6.7 Win XP

[jkwarras]

Hi,

I don't know if this has been reported before. I recently compressed 2 AC3 tracks to 2 ogg vorbis files latest besweet 1.5b22, i muxed it into the video file (into mkv) and run in MPC 6.4.6.7. At my surprise (before i run it without any problem) the sound start "crashing" (sorry, i don't know how to explain but it sound something like that: ñññÑÑÑÑssssrrrrrrggggrrgrrrhrhrhhhhhhhhhhHHHHHH...). The sound remains like that while video file playback without problems. If i play the file alone (not muxed into the video file) the same thing happens. 2 things can happen:

1) If i stop the file and play it again sometiems it works fine and video/audio plays fine.

2) MPC crash and windows close the program.

If i use Windows media player 6.4 it plays fine.

- MPC version: 6.4.6.7 Windows Xp
- Dshowfilter: CoreVorbis 1.0b5
- OggDS 0.9.9.6

Someone knows somethign about it?

Hello jkwarras,
I tried your settings and the DS filters,but I could not find any problem with MPC.I think there should be no problem as the vorbis is played through DS filter that all players are allowed to use.So there will be no difference to what player you use.May be corrupt MPC .(just possibility.....:D ).If it had beed played with its internal builtin filters,there can be a problem.But we know its not.

BTW,I used a stereo file.

I know is strange as it seems like a Dshow playback problem, but only happens into MPC. Disabling Matroska splitter doesn't resolve this thing. The strage thing is that most of the times just stoping the video, and then pressing play again resolve the "crashing" sound.

And i can teel you that the sound IS horrible, even if playing it once. I will see if i can resolve the problem.I will try an old version of MPC, reinstall the Vorbis Dshowfilter, blabla and see what happens.

Turn on the "16 bits decoding" in CoreVorbis decoder Info property page.

I will. BTW, what is this for?

[ChristianHJW]

Some soundcards require this ....

That definitely is not sound card related,if it was that,then how could he play in WMP6.4?
Different decoding for different players??

[jkwarras]

Don't ask me why, but it seems that enabling 16bits in Corevorbis resolve the problem. Thanks for your help :)

[Tuning]

:confused: Can anybody explain this?

[jkwarras]

I can't. The problem was with MPC, with others players it works fine without enabling 16bits in CoreVorbis. :confused:

I'd be glad to test a shorter sample file producing such noises. Could you email me one? (1-2MB max)

Sure, what do you need? Sound Vorbis file or Muxed matroska file? As i said the file by itself doesn't crash and play well, only causes trouble when playing muxed inside a matroska.

And where do i email you this?

That makes me wonder why the developers make the less compatible option the default... :rolleyes:

[gabest]

jkwarras: I almost forgot to reply you, only the notification email sent after LordDethstar's comment reminded me :) In the mkv you uploaded the sound started a bit late (I thought it would end before I can hear anything :D), but wasn't making such horrible noises at all. Isn't mpc loading some other autoloading filters at you? Have you tried disabling/enabling the audio switcher?

Sorry about the audio starting so late, i didn't really check it, just pick the first minute of the movie
:stupid:

I didn't try to disable the audio switcher, but i will and see what happens. I don't load another filter, i was using matrix mixer but i disabled the filter. Maybe is a Dshow problem with Vorbis, i will try to uninstall OGGDS and CoreVorbis and reinstall again. I did once but didn't solve the issue. I'll post results in the evening.

[jkwarras]

I've just check this:

- Enabling/Disabling CoreVorbis 16bits decoding
- Disabling mpc audio-switcher
- Enabling/disabling all internal filters
- Uninstall/reinstall OGGDS - CoreVorbis

Can you believe it? NO way to reproduce the original "crashing" sound. NO way at all. Everything turns fine. Maybe it's the first time i'm angry because of it :D I've used the same problematic matroska file.

So at least, i think this isn't really a MPC behaviour. If any time this happen again to me, i'll report. Gabest, sorry about this and keep the absolutely good work!:)

Regards

PS: Off topic :p Is there any plans to show matroska tags into MPC (not only title) and attachements?

[Ramirez]

Well, I can easily reproduce the "crashing sound" here, AFAIK this problem has nothing in common with MPC or any other player and it's purely related to ability (or inability) of some audio cards to handle 48KHZ/32 bit audio decoding.

@jkwarras: onboard AC97? / SB-Life card?

SoundBlaster. Vorbis at 48hz. I had the same problem yesterday but with a OGM file. Again only happens in MPC and no in WMP9 or others, but a either don't think is related to MPC, but Dshow or as you point Sound card problem. But i didn't had this issue before.

As usual: Stoping playback and playing again resolve the problem. Enabling "16 bits decoding" in COreVorbis resolve the problem in MPC, BUT disabling it again will not reproduce the crashing sound again.

[kittychan]

yooooo

As jkwarras I have the problem of playing ogg sound in a OGM (or mkv) file with MPC.
As him I can play the samefile with any other player without any crash sound.

But I CAN NOT solve the problem by enable 16bit decoding!!!!????

Can you help me??

Try this (it has works for me resolving the problem with a persistent crashing vorbis OGM/MKV file in MPC):

1) Open the crashing file in MPC. You'lll get the usual GGRGggdgduydgud sound :p
2) Enable "16 bits decoding"
3) Close the file and reopen it in MPC. If sound is good no need to do anything else. If the problem still try to open the file into another player like WMplayer 9, and then reopne it again in MPC.

This sounds silly i know, but with some files, i don't know why, it has work for me.

Another thing you might try is to reinstall OGGDS filters and don't use CoreVorbis and see if helps (still you'll get problems with Vorbis in Matroska as it's needed to play correctly).

Regards

[kittychan]

yoooooo

thank you for your reply ^_-

1) Open the crashing file in MPC. You'lll get the usual GGRGggdgduydgud sound

easy, I got many of them :(
But I follow part 2 and 3 but no way, always get bad sound....
If it can help you to help me :) I have tested others situations...

ogg in any container (mkv, ogm) produces the crashy sound (in MPC ONLY)...
whereas mp3 in the same container are ok.
I have tried oggds0995 (and set 16 bit decoding) ->crashy in MPC
I have tried CoreVorbis 1.0b5 (and set 16 bit decoding) ->crashy in MPC
I have tried oggds0996 (and set 16 bit decoding) ->only sound in one of my two speaker in MPC :scared:

Still trying...

kittychan

[kittychan]

yoooooo

I SOLVED THE PROBLEM!!!
(sorry to shout it loud but so much trys for such a "little" problem!!!)

ok, no 16bit decoding or enable/disable filter....

just go to mpc Option-->Playback-->output
and set "directshow audio" to "Default directsound device" intead of "Default waveout device"....
and everything goes well :) (at least on my pc)

Hope it can help others will same problem ^^

Oh my god, i will try it right away and see if it works :)

Another issues i'm having with MPC lately is with vbr MP3 in ogm/mkv: i have sort of jumps when playback, sounds like a bad downloaded mp3 filem from kazaa :p just don't know what happens because plays fine in other players.

In the german doom9/Gleitz forum, and in the CoreCodec forum, we also talked with ChristianHJW about crackling sound in MKV movies with multiplexed Vorbis audio, especially with more than one audio stream.

Removing the OggDS filters (0.9.9.5) completely in favor of CoreVorbis was no option, because CoreVorbis did not handle the playback of pure Vorbis audio files (in the version which was current during this talk), only audio streams inside Matroska movies.

OggDS filters Version 0.9.9.6 shall now solve this problem, they were split into a separate splitter and decoder, and shall use CoreVorbis as decoder if it is installed, and the OggDS decoder only otherwise. But I heard rumours about other problems with this version (no details, though...).
__

Always changing between DirectSound (probably good for Vorbis) and waveOut (supposedly better für S/P-DIF AC3 output) may result into severe hazzle, I'm afraid... :rolleyes:

Something very strange happens when i play ogm or avi with ogg in mpc 6.4.6.* series. The file just doesn't work. The box opens and then closes itself. Very strange, because it works with mpc 6.4.5.* series, and with bs player. By the way, i encoded it, so it won t be a codec problem.

I saw many problems with ogg in mpc 6.4.6.*, but never this one i guess.

Thanks :)

Version 0.9.9.6 didn't solve the problem for me. Same issue regarding Ogg vorbis in OGM or MKV, using Corevorbis. And i have the same issues with MP3 (wargles), so has nothing to do with Corevorbis decoder. It's obviously related to MKV or OGM format in MPC. Others players just play it fine. With MP3 vbr, the "wargling" (sound like a bad downloaded song from Kazaaa, doing sort of "grhtygggg" for a 10th second at random time) doesn't disappear when stopping the file and replaying it. I must admit that i don't know what is the problem, but it seems that last MPC version resolves the problem.

Reinstall OGGDS (whatever version you're using) and install Corevorbis decoder. See if the problem still there. For Avi with OGG, i don't really know but as it's a hack (and i've never use it), you need a special ogg decoder (is this correct?).

[LigH]

Ogg Vorbis in AVI (via Nandub) may work, but will get out of sync or stop playing the sound when the playback discontinues (skipping, pausing, ...).

A DirectShow filter may work, or the outdated Vorbis ACM may be useful - I'm not sure here.
__

Also, no solution for me: I recently downloaded any kind of OggDS or CoreVorbis decoder I could get, and will start deinstalling and selectively installing any combination, and check if one helps... I have a movie with two Vorbis audio streams as OGM and as MKV, and both have crackling sound (the louder the audio, the more crackling - up to choppy video playback; as if the VBR audio brings the movie out of sync). BTW: I only have a poor Duron-800; decoding speed might be one edge I'm facing here!
