AMD HD5450 some 1080p files are choppy

[pdp76]

Using an AMD HD5450 and Windows Media Player, some 1080P 60fps files have very choppy playback during the scenes with a lot of movement, namely the files I recorded with a GoPro. I always thought the HD5450 could handle 1080p60 without a problem at all. I've been using the default drivers detected by Windows 8.1 which are a few months older than the ones from AMDs website, but using the latest drivers from AMDs website doesn't seem to help. These files play just fine on my other machines, one has an nVidia GT240 and another a Haswell Intel GPU on a G3220 CPU. Also, if I force software decoding using VLC, the files play fine on the machine with the HD5450. Below is a MediaInfo dump of the mp4 file, and ideas?

it can decode 1080p with ease... are your drivers mismatched? uninstall and reinstall them

I uninstalled the latest ones from Windows update and tried the latest drivers from AMD, no improvement, so I uninstalled those and went with the Windows 8.1 default drivers again.

As you can see from the MediaInfo dump, this file's video bitrate is 30Mbps. I can play other 1080p videos with lower bitrates with no issues. So saying "decode 1080p with ease" may need some qualifiers.

I have that exact same card in my Dell Studo 1558 and it has no issues decoding at 1080p from any source that I have IE Sony handicam, bd-rom, dash cam, etc...

Do you know if any of the 1080p files you've played are H264 and have at least 30Mbps bitrate? I'm wondering if the bitrate has anything to do with why I'm getting choppy video.

Any chance you can upload the video for download? Like many people here, I have a HD 5450 for HTPC use. So at least we can confirm whether it's an issue on your end or just a limitation of the AMD's drivers.

This is likely the problem. My 6950 only lists support for L4.1, so I doubt something in the 5xxx series surpasses that. Best bet would be to use ffmpeg to re-encode it to the lower profile. The UVD chips that handle acceleration should support up to 40Mbits.

transformers (all of them)
James Bond (the last 3)
Plus many other movies that go past 30... video never slows down...

This is exactly along the lines of what I was expected, thanks for pointing it out, I'll experiment with this more.

That's a really good idea. I'll try and record a new clip that plays choppy on my HD5450 and upload it somewhere.
