Does mpeg1 stream in a browser on a Mac

by DutchPol / October 29, 2013 1:00 AM PDT

First, I'm a Mac-nitwit but the following has been dropped on my doorstep:
The company where I work has a lot of MPEG1 files and our customers stream these. Part of our customers use Mac-computers and different browsers. The website uses VLC-Player to stream the video. This doesn't work on newer versions of OSX and / or browsers.
What is the alternative? Various sources reported "NONE".
I found that curious so I checked the QuickTime specs and they stated that mpeg1 streaming is possible. In a quick trial it seemed that QuickTime is first downloading the file before playing it, so it's not really streaming.
So my question is: Is there a (short term) alternative to stream mpeg1 on a Mac, preferably on most common browsers. And yes, we are planning to transcode to another format but that takes time.

It might not stream.

MPEG1 is a pretty old encoding and to stream (and I'm taking your word it must stream) the video and audio content must all be together inside a small space. If the mpeg1 file is not consecutive and the audio packets are too far apart or segmented it might not "stream." So while it is possible, did you really want to take courses and read books about all this?

And finally, you may have to buckle a little and try Chrome as a short term solution. Your post has good questions but most of it seems to scream why and tell me you are just starting your work in this area. Sorry but I can't condense all that would be needed in this small space except to write it's the wrong encoding for reliable streaming. Too old.

Some explanation

Thanks Bob for your reply,

As to the "Why": More then 10 years ago this format was choosen in combination with the IPV Spectreview Encoder to make a digital browsing copy of Digi-Beta Tapes with a frame accurate reference to the timecode on the tapes. As far as I know, IPV was the only company in those days that could provide for the reference. Making High-Res copies wasn't an option then because of the volume (now 600,000+ clips also in High-Res).
Times have changed but it's still streaming ok on windows machines so I guess the format isn't too old but the mac -software too new Happy
You can imagine that transcoding this volume isn't done in a day and we're looking for a more short-term solution for our mac-users. We'll have a look now at real time transcoding to mp4.
Could you tell me what you mean by "try Chrome"? The Chrome video player? Or Chrome + QuickTime?
Thanks anyway for your time.

Just Chrome.

Chrome has some video players built in.

Sorry but as Apple and other makers deprecate and stop trying to work around the MPEG1/2 streaming issues, you may find them drop that as paying the staff to tweak things isn't worth it anymore.

I know that may upset some but it's well over a decade since streaming encoding became available. Yes, I hear you "it used to work" but as it's costly to implement or carry legacy code over and possibly other issues such as exploitation of the OS/Browser you see deprecation of features.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
