[MPlayer-users] 3D-Stereo video in a TS issue

Mon Jan 20 15:00:29 CET 2014

Hi Daniel,

I tried the program on your provided sample. Although the remuxing works,
JM is not able to decode the file. Not sure what went wrong there, I have
to check. My own AVCHD 3D files work fine.

Concerning the huge files: that was only meant for the commercial mvc to avi tool.
My recoding tool uses fifo files, so no disk space is used for the intermediate
RAW video files. The video can be converted to (H)-SBS or (H)-TAB to make it
compatible for todays TV-sets. Depends what your goals are ...?

I write back to you if I finish debugging.

Marco
