Title: New JRiver Video Codec
Post by: JimH on November 01, 2002, 12:01:36 pm
The latest build of MJ, 9.0.71, that slid out the backdoor last night has something that is very big for us.  It is the first time we've shipped a new video codec that Matt wrote recently, with some help from Nikolay, Yaobing, and Bob.  It is a huge accomplishment.

We wrote our own because there were problems with others available.  The main problem was that they weren't fast enough to do real-time TV recording.  Ours is.  Our goal is to be able to deliver good quality 30 frame per second video on a 1Ghz Pentium 4.  We may be there.

If you have a TV card and want to try it, be aware that it is still really ragged.  We didn't intend to release this build but we needed to in order to solve the expiration problem people discovered last night with the previous beta.

Here are Matt's notes in e-mail to me last night:

"Filters are supposed to get registered, but if things aren't working, try registering the *.ax files by hand.  Also, 640x240x29.97fps looks like the way to go with an ATI card."

TV playback with pause, fast-forward, and rewind all seem to work in MJ now. (Ctrl+P, Ctrl+Left, Ctrl+Right)  However, there are a few problems:

- can't turn timeshift playback off
- when playing timeshifted content, resizing doesn't work -- so, start in full screen
- right-click isn't working for me anymore

You will need as much as 3GB of free disk space to use this, since it has a circular buffer that is 33 minutes long.  That's also as far back as you could go on rewind.

If you're interested in testing, I may have a slightly better TV control tonight.  Just e-mail me at jimh @ jriver.com.

Congratulations to the team on this one!

I don't know if this build is the cause to my MJ freezing but the previous one had no problems. The entire tree view/content view is frozen. All other parts work fine. Seems like a video problem.

I had to upgrade because of the expire notice. Never seen this before with any other MJ builds.

Maybe it has something to do with the new changes? I'll keep looking into it.

I noticed two issues with the new codec:

1. I only have 700 megs of free space (too much porn) and the codec kept crashing.

2. I have an ATI TV Wonder USB.  Windows XP started reporting that the USB bus bandwidth was being overrun and my other USB devices started shutting down.

An old issue that I had is that I've never been able to get the sound to work with this device.

Oh boy, it's hard to add much to this thread.

Still, thanks for the birthday well wishes :)
