Is there any way to get past this error and have ffmpeg complete the copy?
If I copy all or at least one subtitle stream from an mpeg file, eg:
$ ffmpeg -i movie.vob -map 0 -codec copy -f vob movie-COPY-ALL.vob
$ ffmpeg -i movie.vob -map 0:0 -map 0:11 -map 0:7 -codec copy -f vob
movie-COPY-SPECIFIC.vob
ffmpeg aborts with a message like this:
[vob @ 0x8789560] Application provided invalid, non monotonically increasing dts
to muxer in stream 2: 325576251 >= 0
av_interleaved_write_frame(): Invalid argument
If no streams are selected or only the video and one or more audio
streams, then it works, even though a similar warning message is
displayed, which appears to apply to the audio stream. If more then one
audio stream is selected, this message is repeated once for each audio
stream:
[vob @ 0x9dd6560] Non-monotonous DTS in output stream 0:1; previous:
333573120, current: 333571738; changing to 333573121. This may result in
incorrect timestamps in the output file.
I assume this must be an issue with one/more of the subtitle streams, but
from what I can tell by viewing them, they're fine. If I look at the
original movie right at the point where ffmpeg aborts, all of the
subtitles are there. ffmpeg seems to "fix" this issue with the audio
streams, can it do the same for the subtitle streams?
I've included output from the "at least one subtitle" case and the default
(no streams selected) case. The 2nd command is pruned a little, but it's
using the exact same ffmpeg and input file.
FYI. movie.vob duration is actually 02:11:44.02 and not 01:09:57.66 as
it's initially reported. ffmpeg shows the correct duration for
"movie-COPY-DEFAULT.vob" after it's completed copying the video and one
audio stream.
