Still debugging. Question, when I do > ffmpeg -i ../owhat.mp3 -loop_input -vframes 90 -i img_0382.jpg -target ntsc-dvd out.vob
I do get a valid file which will help me to debug the issue below however what I noticed is that the audio, which is one channel, 2.5 sec 44.1kHz will turn into 2 channels 48kHz (as expected) but about 3.3 seconds. Any ideas anyone on why this is happening and how to fix it ?
