i'm trying to create a video lesson. with time it will grow much bigger in size. currently it's 51mb made of video and images and audio.
i converted it with Free WebM Video Converter to normal quality 640x360 vp8 360p 1.5mbit's vorbis 112 kbit/s 44.1 khz
when i play in on mobile phone or tablet it doesn't not jump to different times at the video as i wish. i can only play it from the beginning. after watching it completely it allows to jump to different times.
i'm really frustrated with the hardness to post a video with html and would really appreciate some tips or explanation for why it's this way.
