Codec imasankhidwa kuti igwirizane ndi VOB - H.264 kwa MP4 yokhala ndi kutalika, H.265 kwa MKV yokhala ndi kukula, VP9 kwa WebM, AV1 kwa ma pipelines atsopano. WMV amabweretsa Microsoft yekha VC-1 kapena WMV3 kanema ndi WMA audio - codecs pafupifupi chilichonse kunja kwa Windows decodes mwachilengedwe. A VOB ali MPEG-2 kanema, AC-3 kapena PCM audio, ndi DVD subpicture subtitle masamba, anagawa mu 1 GB segments ndi DVD spec.

Kodi ndingawonjezera ma subtitle osankhika pamene fayilo ndi VOB?
