DivX Plus HD - Unable to stream videos through WebPlayer

[wtopace]

Hello, I am relatively new to video transcoding, and have been trying off and on for a few weeks to create a Divx Plus HD compatible H.264 MKV file. I am able to create the video files, but the web player keeps giving the following error message:

DivX Web Player: playback error
=================================
The downloaded video file is not a DivX file.

If anyone more experienced than myself can find the problem with my encoded file, I would be very grateful.

If you would like a 5 second sample of the transcoded file (900KB) please PM me and I will provide you a link to my webserver.

Thanks,
Wes

The downloaded video file is not a DivX file.

Says it all i they use something inside the .MKV to identify it as such without this boom ;)
so best way to confirm that use their applications to create a DivX .MKV i would guess that works fine, maybe they even check the bitstream itself :D

ffmpeg -t 5 -y -i SCC.S02E19.avi -s 1280x720 -maxrate 20000000 -bufsize 25000 -bf 3 -g 96 -qmax 51 -acodec aac -ab 128k -ac 2 -r 1001/24 -vcodec libx264 -vpre hq -crf 22 -threads 0 video.mkvSome unrelated notes about this commandline:

1) Maybe you meant bufsize 25M and maxrate 20M? They're both in bits.
2) -qmax 51 is part of -vpre hq, so you don't have to include qmax.

Thanks for the quick reply! Right after I posted this I did "x264 -h" and "ffmpeg -h" and realized that the units for both of those are different (kbits vs bits). That did not fix the problem, however, it looks like there has been an update to the WebPlayer that did fix it, so everything is working fine now. I will go dig around the DivX website and see if I can find a changelog to see what changed. Thank you guys for the help!

BTW, Stax76 has added DivX Plus HD settings to the latest version of StaxRip: http://forum.doom9.org/showthread.php?t=102652&page=126 (thanks, dude!)

And you can also consult our developer portal (developer.divx.com) on how to use x264 for encoding compatible streams for DivX Plus HD.

We'll be putting together some recommendations for DivX Plus HD encoding for web streaming via the DivX Plus Web Player soon, we just want to make sure we get enough feedback from content publishers, developers of encoder GUIs and other users so we come up with some settings that work for the most popular use cases.

For now, we encourage you to experiment and share what's working best for you.

edit: problem solved, problem was the source was on my hard drive instead of a web server.

@ porfitron
Are you planing on Hardware Decoding support for the Web Player i mean come on it's the Buzzword currently though i remember Mainconcept failed back then implementing even DXVA playback when Elecard got it right hehe :D
