Problems with Handbrake after MakeMKV

[captain]

OK, I've re-ripped episode one from Earth: Biography disc 1, using MakeMKV 1.5.7. Same failure with VLC - audio only.

Hi, common problem with VLC! If you notice your video is VC-1 which is causing issue.

What version of VLC?

[captain]

Well, *I* didn't chose VC-1. MakeMKV did! Also, the Baraka rip is in VC-1 format too, so why does it play in VLC but Earth:Biography episodes don't?

As I wrote before, I'm using the latest VLC available for easy install (i.e. no crazy Beta versions here): Version 1.0.5 Goldeneye (Intel 32bit)

[crowfax]

Well, *I* didn't chose VC-1. MakeMKV did!

The people who mastered the blu-ray picked VC-1. MakeMKV simply re-packed it into an MKV container.

Anyway... try the latest VLC nightly: http://nightlies.videolan.org/. See if that helps any.

[captain]

So, looking more closely at my own data I see that the video streams differ in the latter part of the description:

This works (i.e. plays back in VLC and can be transcoded by Handbrake to play on AppleTV):
Frame rate : 23.976 fps
Chroma subsampling : 4:2:0
Bit depth : 8 bits
Scan type : Progressive

This fails (i.e. won't do those things):
Frame rate : 29.970 fps
Resolution : 8 bits
Colorimetry : 4:2:0
Scan type : Interlaced
Scan order : Top Field First
Bits/(Pixel*Frame) : 0.309
Stream size : 6.09 GiB (91%)

I'm hoping that Mike has the solution. My first thought was that maybe a dual core 3GHz machine just maybe can't decode that much data. But then I thought, no, I've pumped more data than that before... plus the VLC error messages were a missing codec problem, not a speed or late problem. I'm still stymied.

Thanks for the suggestion. I got the latest nightly build, and got the same results: audio plays, no video at all. Here's the tail end of VLC's message log. The first 10,000 messages are mostly more of the first three avocodec warning lines here:

From what I've read so far on other pages, the problem is that VC-1 interlaced (1080i) is not supported by most of the available software decoders. I have one of those MKVs myself and neither VLC nor MPlayer Extended (without binary codecs) where able to decode the video stream. My only success with VC-1 interlaced was MPlayer Extended with binary codecs, but even with that combination the picture will stall after about 1 or 2 mins.

[captain]

Oy vey! Once again, MicroS**t hoses us all. Any solutions yet?
There MUST be some way to transcode this MicroS**t crap into a decent format! ...no? :-/
I mean, come on, if it's not decodable how are people supposed to WATCH the damn movies?? If we can decode it to watch it, then we ought to be able to decode it to transcode it to be able to watch it on our equipment that requires specific formats, e.g. my stupid AppleTV. sigh.
I wish I were a good coder and cryptologist. I'd crack this thing and release it.

Fond though I am of blaming Microsoft as much as possible, I'm not sure we can in this case. I've hit the same problem with the BBC disks of Bleak House. In fact, this is (I think) not an uncommon for BBC disks to be done in 1080i. I'm converting my HD-DVDs to Apple TV files. I have a workflow worked out, but I have to do all the early stuff in Windows using things like EVODemux and eac3to. I've spent the last few days looking for a method to convert the 1080i without resorting to really arcane instructions or weird programmes, without any real success. If I demux them, I can produce a remuxed file that either has a screwed-up picture or no picture at all.

The video plays on the machine they were intended for a Blu-ray player ; )

Try the OSX version of XBMC and see if they play. As to Handbrake it doesn't really support Blu-rays all that well as an input format yet, the Windows x264 encoders like Ripbot264 are much better in this regard if you have access to bootcamp/virtual PC Ripbot264 is worth trying.

[captain]

Thanks for the XBMC pointer! I'll give that a try. I'm surprised there's not a plug in for QuickTime in the Perian tool box to allow VC-1 decoding!
