Hello,

Thanks for this community.

First, why I with following cli it can't copy all streams of a vob files?
Feature not implemented, I get error -1?

ffmpeg -i VTS_01_4_ORIGINAL.vob -map 0 -c copy oscar4.vob

Could not write header for output file #0 (incorrect codec parameters ?):
Error number -1 occurred



Second, if I copy all streams except dvd_nav_packet
ffmpeg -i VTS_01_4_ORIGINAL.vob -map 0:0 -map 0:1 -map 0:2 -map 0:3 -map
0:4 -map 0:5 -c:v copy  -c:a:0 copy -c:a:1 copy -c:a:2 copy -c:s:0 copy
-c:s:1 copy VTS_01_4_N.vob

Than why is the ouput order changed?

ffmpeg -i VTS_01_4_N.vob

At least one output file must be specified


Thanks,

Philippe

P.S. My initial objective is to repair a scratched DVD and concat all its
vob into a single one. In this case VTS_01_4.vob is scratched and file
jerks or freeze even read from pc, that's why I want to "re-write" it.
