[FFmpeg-user] how ffmpeg computes(find)canvas_size for subtitles
Hi. I record broadcast from French TNT (1920:1080i and subtitles dvbsub) If i want to change the container to mp4 i must transform dvbsub to dvdsub. For example: ffmpeg -y -fix_sub_duration -i '/home/cavelier2/Videos/Irma la douce (VM).ts' -map 0:s -c:s dvdsub -f matroska sub.mkv or mp4. I get the message: canvas_size(0:0) is too small(659:543) for render. With french tnt i got some differents canvas according to differents channels with the same code line: canvas = 659:543 || canvas = 381:549 || canvas = 711:549 . Question: how ffmpeg computes this canvas ? Thanks. -- cordialement jean-jacques.
