Converting DVD image with subtitles to MKV using avconv
16 janvier 2016, par Carlos Eugenio Thompson PinzónThis is the procedure I know to convert a DVD image to another videoformat (v.g. MP4) :
- concatenate the
VTS_01_
n.VOB
files insideVIDEO_TS
folder (for n >= 0) into a single VOB file. - use
avconv
orffmpeg
in order to convert that VOB into another format.
So far so good, however now I want to convert the DVD image with the subtitles. As far as I know the MKV format supports subtitles, so it seems an obvious choice. Alternatively I might use any other format with hard subtitles (subtitles as part of the video image).
However, the subtitle encoding in the DVD image is
dvdsub
and I get the following errorOnly SUBTITLE_ASS type supported.
Subtitle encoding failedHowever, when running
avconv -codecs
I get :...
DES dvdsub DVD subtitles
...And the
-c:s copy
switch, while it prevents the command to fail, it does not seem to produce a subtitle that the player can understand.So, how can I create
ass
subtitles fromdvdsub
usingavconv
?My VOB file has eight subtitle channels and two audio channels. The Ubuntu video app does not show any subtitles, and only the first audio channel seems to be working, do the DVD image might be broken.
Another file, for a double-layer DVD, displays the Subtitle encoding error, however when using the
-c:s copy
switch it further displays :Application provided invalid, non monotonically increasing dts to muxer in stream 2: 49 >= 49
av_interleaved_write_frame(): Invalid argumentThank you in advance for any ideas on how to solve these problems.
(I am using Ubuntu where
ffmpeg
is an alias foravconv
. I know it is possible to install the real ffmpeg but so far I have not done so.)
