Sierra deleted the QuicktimeMpeg2.component fil...

Hi there,

It seems like Sierra deleted the "QuicktimeMpeg2.component" file from the Quicktime folder (Macintosh HD/System/Library/Quicktime), which results in MpegStreamclip (and as far as i can tell Compressor too) not being able to work anymore with Mpeg2 files.

I have the QuicktimeMpeg2.component file from an old backup, but the system won't let me drop it back inside the Quicktime folder.

Anyone else experiencing problems with MpegStreamclip and Mpeg2 files? Any ideas how to solve this?

thanks!

Apple went ahead and disabled the use of MPEG Streamclip via destroying the ability to install the MPEG2 Playback Component in Sierra, which kills just about the handiest piece of software a video editor could ask for. This is utterly unreasonable and totally irrational, not unlike their decision to make Final Cut unusable for professionals. I don't know why there's so much hostility, but this is the latest wound in a long divorce process between cutters and Apple.

I wonder what the "AppleMPEG2Codec.component" does in "/Library/QuickTime/".

It is there, but won't work with MPEG Streamclip (my go-to video converter for many years):

I actually have three installed: one by Apple, one I purchased several years ago, and the one that got installed by following MPEG's instructions above.

@AJOrion:

I have tested MPEG Streamclip with El Capitan and it works there. I have not tested this in Sierra; mainly because of the software I use for my video projects which is not compatible with either El Capitan or Sierra, so I usually boot into my Mavericks partition to do the work there.

Sierra prevents any editing to the system folder with a clamp-down of permissions heretofore unseen in any Apple OS. Even if you had a MPEG-2 Component, you couldn't drag it into the Quicktime library for that reason. The only workaround I had was to try to scavenge a .DMG file from the black market, as per the MPEG Streamclip installer requirement. It appears to have worked, but this was a supremely byzantine process to use a piece of freeware I thought nothing about until reinstalling it today.

Yes, I know about the SIP feature. Since there are two Quicktime folders, have you tried the other one - just in case that might work? One is in HD > System > Library (which, I am assuming, you were referring to?) and the other is in HD > Library.

FWIW, I am now on my Sierra machine and - most likely because it was all installed before I installed Sierra - I just tried MPEG Streamclip. It works in Sierra.

For those reasons (and a dozen others), I maintain bootable clones of every OS version I have. It is - in my humble opinion - by far the easiest way to get around this type of problem: just boot from an earlier version which includes the software you want, erase the internal drive, and clone the system back. You can then update to a newer OS and the software still works.

There have actually been three QuickTime folders.

/System/Library/QuickTime

/Library/QuickTime

~/Library/QuickTime   (i.e. in the Users own home directory and Library folder)

I am not sure if the one in the users home directory still works but obviously it would be accessible to a user.

MPEG StreamClip will work without the MPEG2 component but it then cannot edit MPEG2 files. I do however use it to edit MPEG4/H.264 files for which it is also excellent - it can even do this without needing to re-encode files unlike QuickTime Player or iMovie.

I also wanted to deal with my old Mpeg2 files with the latest beta of "MPEG Streamclip 1.9.3b8" on Sierra but could do nothing with it.

My solution, so far, was making a Win app wrapper of "Media Coder" using Wineskin, and it re-encoded to H.264 very well.

(Since Win apps' UI are not user-friendly as Mac's, took me a little time for adjusting the settings though)

Tested with:

1. Sierra (macOS 10.12.4)
2. Wineskin( Wrapper ver. 2.6.2 with Engine ver. WS9Wine2.6 )
3. Media Coder Full Pack, 32-bit Portable 0.8.49.5890

Hope it helps for someone who had the same problem. =)

FYI this was written about on another website (can't remember which one) which suggested placing the MPEG2 component under ~Library/Quicktime. This restored MPEG Streamclip function for me and confirmed to me that Apple is seriously out of control.

You can let Apple know you're convinced they are seriously out of control here…

FWIW, I've had the MPEG2 Component installed for years and Sierra did not uninstall it. It is still there and MPEG Streamclip works well.

Hi, Do you mind elaborating on what you just wrote? I only understood half of it hahaha.

By half I meant 1/4

I just had to to resurrect 20 year old source video that was captured on a Mac 8100 using a Radius VideoVision Studio card so it had the VideoVision codec. Quicktime on Sierra would not play or convert this video.  I was able to find a VideoVision transcoder plugin for Quicktime from 2006.  To get it to work, I went to ~/Library (~ being the user you are logged in as or the full path is drive/User/username/Library) I had to create the Quicktime folder since none existed.  I pasted the plugin into this Quicktime folder.  It Worked!  Quicktime 7 will play the video. Quicktime 10.4 will open and covert on open nicely.  Hope this helps any who might need to get an older Quicktime plugin/component to work.

Glad you got it working but not sure why you didn't have a QuickTime folder. Should be at least two.

This is how I got Mpeg Streamclip working with MPEG-2 under OS X El Capitan:

You need two installers:

MPEG_Streamclip_1.9.3b8.dmg

(https://www.squared5.com/svideo/mpeg-streamclip-mac.html)

QuickTimeMPEG2.dmg

(https://tradownload.biz/results/quicktimempeg2-dmg-mac.html)

Assuming MPEG Streamclip 1.9.3b8 is already installed:

1. Open the disk image of QuickTimeMPEG2.dmg (do not install!)

2. Open the disk image of MPEG_Streamclip_1.9.3b8.dmg.

3. Locate "Utility MPEG2 Component M. Lion.app" in the latter one.

4. Run it. Done.
