Hi all.

I have some m2ts files shot with my Panasonic SD-10 camera. Playing any of these files causes MC to crash if the "HW accelerate video" option is ticked. It happens with both Red October Standard and HQ.

These files play ok in VLC and PotPlayer64.

I have a very limited supply of m2ts from other sources to test, but they all seem to play fine in MC.

Any ideas about why do I have to untick this option in order to play these files in MC?

It's a desktop PC, i5-2500 on a GA mobo, using the embedded Intel HD graphics adapter.

Are you able to upload a short sample somewhere?

I hope this will do:

I'm remote at present so can not test for 24hrs but I'm sure others will do before then!

The clip plays fine here with HW acceleration enabled. Just to be sure that it was really using HW acceleration, I configured a custom filter chain based on ROHQ with LAV Video Decoder added and set to DXVA copy back. Still the clip played fine with copy back confirmed working in LAVs property page.

It could be an Intel thing. I have an AMD 7750. But also check you are using the latest version of MC.

Thanks for checking it. The MC version is current 18.x.128.

Could it be some then some MC setting that I've fiddled with?

Hard to think of anything assuming you are using Red October.

For better diagnosis I would try Red October Standard and HQ. Any difference? Then I would install the latest version of LAV, independent of MC (http://forum.doom9.org/showthread.php?t=156191), then set Video Mode to "custom" based on RO Std or HQ (whatever you are using now) and add LAV as a video decoder. You can then try different LAV Decoding options to see which, if any, work.

As I said in the first post, I already tried HQ+ST. MC hangs in both cases with these files. I'm sure it's some setting somewhere, but which one?

Hi yannis,

this is a bug in the LAV Video decoder, specifically the Intel HW Acceleration module.
I have fixed the crash, and the video now plays fine.

A new version of the decoder will be released soon, and hopefully then also be in MC18 some time next week.

Thanks for the sample file, and sorry for the inconvenience!

Great! Glad I helped a little.

And thank you all very much for your time.
