vcodec copy produces broken AVCHD files

[Elliott]

Summary of the bug:
Using ffmpeg to rewrap an AVCHD .mts file to .mov results in a file which does not play in Davinci Resolve or Adobe Premiere, and the OS X Finder thumbnail shows all white. If instead, I use the application ​ClipWrap to do this conversion, I don't have any of these problems. I got a small explanation from the ClipWrap developer:

We still need to index every PES packet in the h264 stream to build a legit QuickTime header and sample table - ffmpeg fudges that, which makes files that are playable but not properly editable.

How to reproduce:

$ ffmpeg -i 00020.MTS -an -vcodec copy 00020.mov

Does the output file play with QuickTime (and WMP)?

[Elliott]

Yes it plays in QuickTime 7, X, and WMP 12.

Update: In addition to the problems I listed before, these files also "crash" DaVinci Resolve 10.0.2.
