Once working .m4v files in QT7.7.4 gives error -2041: invalid sample description

As title states, I recently reinstalled iTunes/Quicktime on my Windows 7 machine and have slowly been adding my .m4v videos as I watch them. All of these videos had been encoded using handbrake to watch on my AppleTV and iDevices. Up until today, I've been able to add my videos fine, and play them through AirPlay to my devices. Today, I tried adding one to watch and I was unable to add it to my iTunes library, and unable to play it in QuickTime and was prompted with the error in the title. I tried playing existing videos to no avail, and was unable to delete and re-add the videos (that had been previously played) to my library. Searching through the community here I've seen 'fixes' to rename file extensions which does not seem to work in my case. I am able to get some .m4v encodes to play, but they were from a different source. To my knowledge no software has been updated, and my workstation has remained up (on) since the videos have last worked.
Thoughts?

sorry to hijack your post but how does one post a new topic on these forums? gota lov apple, i've been here to the website many times and the post a new topic button is gone? why is this when i am logged in?! apple needs to stop making commercials and spend more time on better products. starting with some basic stuff on the forums.

What is a error 2041; invalid sample description mean in quicktime when im trying to open a coverted mp4 file?

Im trying to import mp4's into itunes ver 11. The ones I have downloaded have gone in fine with a bit of tinkering but when i converted avi files to mp4 and try to open them in quicktime to check them i get an error saying ( error 2041: invalid sample description was found in the movie). These files wont show up in itunes, the progress bar starts loading them but then nothing appears anywhere even home video folder, Nothing. The mp4 files work in VLC player but not quicktime.
I used dvd fab to covert them. Any help would be greatly appreciated.
Thank

I had the same problem few days ago.
It appears that MP4 format is a lot restricted, and Quicktime/iTunes does not communicate a lot about that. Tipically, Quicktime does not think that MPeg 4 + MP3 is an acceptable MP4 compination.
To make them a lot more permissive, just try to rename the file extension to .m4v, it'll do the job in many cases, and worked for me on a lot of files.
Best regards

Error -2041: Invalid Sample Description on every MP4 file that I create.

OK, Apple already has a poor reputation in my book and this just adds to it, because I'm not the only one struggling with this problem. Numerous students in my classes have complained about the same thing. We are training on Adobe After Effects 7.0 and our instructor has requested that we post our files as MP4 files, so we have tried MP4 Standard, MP4 Improved, and the H.264 settings. Regardless of which setting we use we get the error:
Error -2041: an invalid sample description was found in the movie
Now why should the software that automatically makes itself the default player for MP4 files not be able to actually open them? We've all downloaded the most recent player.
Clearly, since I'm not the only one with the issue, there is a problem with the software that needs to be addressed. For now, I am changing the default player to something that can actually open and play the files without crying about it.

Error 2041 : invalid sample description (mp4 video file)

What does this error mean? I emailed a video clip to 2 different computers. The computer running windows2000 and quicktime player v6.4 plays the clip just fine. The computer running Windows Vista Home and quicktime player 7.4.5 gives the above error.... what is the problem ?

Flash catalyst 5 file opened in flash builder gives "Error #2032"

Hi there,
As the title suggests I created a file in Flash catalyst 5 and to give it resizeability I edited it in flash builder to add preinitialize="systemManager.stage.scaleMode='showAll'" in main.xhtml as I found suggested in the forums.
The problem is when I try to load this in my web browser I get the #2032 error and nothing happens.
Does anybody more knowledgeable than me have any ideas as to why I might be getting this error?
Best regards,
Gareth

I'll give you the short answer, Flash Catalyst is built on top of the Flex Framework and it's libraries. When you launch or load a FC swf, it will contact the Adobe servers to check the status of various libraries. Since you are loading this into a standard Flash Professional created swf, you are by passing some of the fallbacks that exist.
If the movieClip that you are creating is just a filler image, and you are just centering the FC swf, then I also recommend using CSS to display the filler and some HTML/CSS to center the content.
Hope this helps a little.
If you did the loading of the FC swf from a Flash Builder based project, you should not have the issue, since it is a Flex based SWF, the framework checks are already handled for you.

Ldifwrite created file used in ldapadd/ldapmodify gives errors

We want to backup entries in the Users container.
1. The ldif file created by ldifwrite:
ldifwrite -c oidtwo -b "cn=Users,dc=dn,dc=dev,dc=pg,dc=gov" -f backup.ldif
2. ldapadd -p 389 -h localhost -D "cn=orcladmin" -w oiddp -f backup.ldif
3. Got errors in orcloci ...in VI we found that the orcloci entries are not formatted properly, and we fixed this manually.
4. We got another error:
adding new entry cn=orcladmin, cn=Users, dc=dn,dc=dev,dc=pg,dc=gov
ldap_add: DSA is unwilling to perform
ldap_add: additional info: You cannot add entries containing authpasswords.
Just wonder if this is the right way to back up this container?
Thanks!

You'll need to remove authpassword attributes as those are created at create time. Its mentioned in one of the steps of moving to a new server (Metalink Note:276688.1). The XSL they used is below:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xml:output method="xml"/>
<xsl:template match="*|@*|node()">
<xsl:copy>
<xsl:apply-templates select="*|@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="attr">
<xsl:choose>
<xsl:when test="@name='authpassword;oid'">
</xsl:when>
<xsl:when test="@name='authpassword;orclcommonpwd'">
</xsl:when>
<xsl:otherwise>
<xsl:copy>
<xsl:apply-templates select="*|@*|node()"/>
</xsl:copy>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
You'll want to start with dumping it to XML:
ldapsearch -h $OID_HOSTNAME -p $OID_PORT -X -D "cn=orcladmin" -w $IAS_PASSWORD -b "cn=users,dc=dev_domain,dc=com" -s sub "objectclass=inetorgperson" > portal_users.xml
Then run that against the XSL to remove the attribute:
xml -f -s del_authpassword.xsl -o portal_users.xml portal_users_new.xml

Files download 90% and then give error message

When I download a large file (e.g., video, app) with Firefox 4, the download moves along fine and, when it's almost complete, the download stops and says the source can no longer be found.
I never had this problem with Firefox 3. Sadly, I now have to use IE when I want to download a file. I don't use IE for anything else and I'd prefer to download files from within Firefox again.

Try running Firefox in [[Safe Mode]]. If it functions properly in that configuration, then one of your add-ons is the culprit.

QuickTime error 23132 with M4v files

i have QuickTime 7 on my system. It has always played my m4v files without problem (typically TV shows and movies bought on iTunes). So tonight I downloaded the latest itunes update (12.1). Everything works fine on iTunes but if I try to now view any of these m4v files in QuickTime it complains with error 23132 and won't play. Pretty irritating. Any ideas, I guess it's DRM related but seeing as my windows machine is authorised in iTunes etc there should be no issue. For what it's worth QuickTime plays MP4 files I have just fine so it's just the m4v files causing the error code. I did notice my QuickTime 7 wasn't latest version so I updated it to the latest, 7.7.6 or something along those lines. But made no difference.
i Am sure the iTunes 12.1 is the trigger here, has anyone else updated to the latest iTunes and now sees this issue in QuickTime with playing their legitimately purchased content?
i Guess it's not the end of the world as iTunes works normally and plays them just great but very occasionally I do like to use quicktime
cheers

"Maybe this has something to do with the DMR restriction on files that you need to have each system with iTunes authorized with your account/id and password to verify you aren't copyrighting any files across systems, even though you are allowed to up to 5."
And that is the very reason I refuse to but Apple products, this assumption that you are guilty so they "restrict" what and how you can play something you have legally PAID for is outrageous.
Playing movies etc through iTunes is a huge pain because it takes up your who system and you can't do anything else while the playing. I have a two screen setup and when quicktime used to work it was on one screen and I could do things on the other, email etc. Now because this DOG quicktime doesn't work anymore iTunes blacks out the second screen when running a movie or TV show.
Just rubbish and I have bought my last item through itunes, I will pay more to buy an actual DVD so I'm not treated like a criminal and can play it on what and when I want.

2nd Audio track from merged .m4v files does not play on iPod Touch

I used Handbrake to encode two .m4v files of a concert DVD that spans two DVDs. I then took those two files and combined them into Quicktime Pro to create a single .m4v file. The file plays fine in QT but when I transfer the file to my ipod, only the first audio track (from the first file) plays. Once the video from the second file plays, the audio is silent. Here's what the movie properties look like:
Enabled Name Start Time Duration Format
====================================================
Y Video Track -- 0:00:00:00 -- 2:21:53:90 -- H.264
Y Audio Track1 -- 0:00:00:00 -- 2:21:53:90 -- AAC
Y Audio Track2 -- 1:27:28:87 -- 0:54:24:02 -- AAC
N Text Track -- 0:00:00:00 -- 2:21:53:90 -- Text
Any suggestions?
Thanks,
Dan

So basically, anytime I combine more than one mp4 file in QT7 Pro, it will always create multiple audio tracks when doing a simple "save as" (vs. export as)
Not exactly. QT has it own set of rules. As you noted, the video track had no problem merging into a single track. This would not have happened if you had merged video compressed differently or added an image/stretched image sequence. Not knowing your specific work flow or settings, I hesitate to make any claims here. Frankly, when merging audio, I normally prefer to use GarageBand when I want to create a single master audio track and still retain control of the other tracks for mixing purposes. However, I could just as well have exported the audio in the original file using QT Pro to a single audio file and used that audio track to replace both original tracks keeping both the original video and chapter tracks. It is all a matter of which work flow you consider easiest for a particular job or project.
If I've exported out my chapter file as a plain text file, how do I go about reintegrating that withing the final mp4 file using QT?
http://www.apple.com/quicktime/tutorials/chaptertracks.html
The above link is a somewhat old tutorial explaining how to create a chapter text track from scratch. Since you already have the chapter track, just refer to the steps indicating how to add the text file back to your main movie file. (Ignore the step that says to set a "Preload" option as this pop-up has been removed.)

I have created a .m4v file from iPhoto and would like to share it with someone else knowing that the file is quiet large (86 Mo), i used to share file with mobileme, how Can I do that with iCloud ? or another way....

In iphoto, I have create a diaporama which I exported to itunes as a m4v file. I would like to share this file with someone but it is too big to send it via email (84 Mo). This file is now in my films in itunes. Is there a way to share it via icloud.
I used to share files using mobileme which I cannot use anymore.
Thanks for your help,
Eric

How recently did you switch? If it's less than 60 days, then Verizon simply reinstates your previous account. The fact that you were on the EDGE plan and mailed the devices back, and they apparently are somewhere in the system, could cause complications, and it might just work out that you just go back on the same plan and they set you up with the same devices. I'm not sure how it will go - but since you are still being billed for the devices...

PC users can't open iMovie .m4v file

my son made a really cute movie in iMovie, and saved it as an iTunes file, which put it in the .m4v format. i emailed the .m4v file to all our family and friends ... and the PC users can't open the file. can i do something about this (ie. save it in a different format)? please explain it to me in real simple terms ... i am a Luddite. thanks!

You could always point out that anyone whould really wants to watch it could download and install the free QT 7 Player in much the same way that many Mac users would have to download and install either a WMV Player or a WMV component for their QT Player.
You realize, of course, things will likely get worse once you start "customizing" your exports of each recipient? My Sister only wants WMV 9 ($50 for Microsoft "approved" bi-directional components), my brother-in-law "prefers" DivX 6 minimum ($20 for the components), my nieces are into YouTube (posted directly from iMovie '08 for the price of iLife '08) and want everything posted there, and my Aunt (whose computer is more than a decade old) only wants MPEG-1 (which I used to make with iVCD (don't remember what that used to cost or Ti Toast 9 at $80) and of course there is always Visual Hub (at just under $24) for all of the others who will settle for older AVI or WMV files. You can also try exporting some of the "less recent" or "older" codecs like MPEG-4/AAC, Sorenson Video, Sorenson 3 Video, H.263, Cinepak, etc. There are dozens of audio and video codecs that can be combined in in hundreds of combination and placed in various file containers but the problem is you will probably never find a single compression format that really satisfies everyone all of the time. So before anyone can "draw you a map," you will have to make a decision as to "down which road you wish to travel."

I have m4v files that have subtitles and sound options they play fine on my computer in itunes and but when i watch them on my apple tv there is video but no sound ... why ?

I have m4v files that have subtitles and sound options they play fine on my computer in itunes and but when i watch them on my apple tv there is video but no sound ... why ? all my other videos are fine and they in mp4 format.

Mov is a container format, you'd need to look at the codec used by the movie file inside the container to know whether it will work with the Apple TV or not.
