How to play avi files on browser
31 janvier 2017, par mvalencaaMy team needs to develop a system that plays avi files on the web. These files are recorded by a hardware whose firmware we don’t have access to. We are trying to negotiate it with the manufacturer to change the file format to mp4, but until now we have nothing.
Because of this, we are trying another manners to make it work. Our first attempt was to use FFMPEG to convert the files to mp4 (or webm or ogg), but this process takes too long because we have to do it everyday with a really huge amount of videos.
We also tried to use FFMPEG’s copy command (which is much faster), but the video always crashes at some point (mainly when we need to navigate in its timeline) and we don’t know why.
So now we are thinking to customize videojs flash player to reproduce the AVI files, but because we don’t have too much experience with video programming and flash, we don’t know if this is possible. Is it possible to write a decoder in action script to read avi files ?
I saw that Youtube and Facebook can play AVI files... How do they do this ? I have already looked a lot about it, but had no success.
