Hi,
I try to encode srt to dvbsub by below command:
/opt/ffmpeg/bin/ffmpeg -canvas_size 1920x1080 -i
/home/me/Arrow_S04_B04.MXF -i /home/me/Arrow_Test_S04_Ep04.srt -map 0:0
-s 1920x1080 -aspect 16:9 -vcodec libx264 -vb 2000k -bufsize 2000k
-maxrate 2000k -map 0:1 -acodec aac -ab 128k -map 1:0 -scodec dvbsub -f
mpegts /home/me/output.ts
The subtitles do not appear in mpv, in a DVB STB and in VLC.
I checked the output that there is dvbsub packets in mpegts. I checked in
details with a dvb subtitle editor that it seems dvbsub do not include
widthxheight info. But subtitles do exists.
I also confirmed wxh is missing by ffmpeg:
/opt/ffmpeg/bin/ffmpeg -i /home/me/output.ts -vcodec copy -acodec copy
-scodec dvbsub -y -f mpegts /dev/null
'''[dvbsub @ 0x7286c0] [IMGUTILS @ 0x7ffee8adda00] Picture size 0x0 is
invalid'''
I think canvas_size do not work for dvbsub right now.
