Carl hi,
Thank you for your reply! Actually i made this question several times last
month (subject: NEED HELP PLEASE!! Soft subtitles DVB subtitles stream,
1080p size problem on direct convert a MPEG-TS video), before someone
answered me, and i really appreciate this!!
So,
Here is my case:
I have a MPEG-TS video file with one video and one audio stream and i am
trying to create a direct video convert with soft subs, by adding a
DVBSUB stream inside
it. My original subs filewas a stl file with greek subs.
After many workarounds i finally managed to add the DVBSUB stream, after
converting the stl file into a sub file with idx. I used the idx, so i get
the palette information correct.
So the command i used is like this (see bellow for complete console output):
ffmpeg -i testvideo.ts -i subtitles.idx -map 0:v -map 0:a -map 1 -c:v copy
-c:a copy -c:s:0 dvbsub -metadata:s:s:0 language=ell -streamid 2:151
output.ts
The video and subtitles size is 1920x1080, but the output.ts file comes out
with wrong subtitles size. It looks like the dvbsub codec converts the
dvbsubs stream in 720x576 size by default, rather 1920x1080??
Is there a way to force the subs into the correct size? Any options
filter or flags?
(Metadata have nothing to do with subs scaling obviously..)
Or, is there another way (another codec maybe) to achieve that?
I may attach any file needed for your help
Thank you in advance!!
Lefteris
