XVID videos transcoding broken

[japzone 0]

I have an old show encoded in XVID inside AVI containers. When I DirectPlay them on a device that supports AVI/XVID, they play fine, but if transcoding kicks in then the video turns into a garbled pixelated mess with tons of macroblocking. The audio sounds fine.

 

This happens on all devices when transcoding.

 

Here are the transcoding logs:

Update:
Managed to find another old XVID in my collection. Strangely, this one transcodes fine.

Try turning off cuvid, it may have just had a problem with that one particular file. Thanks.

By cuvid do you mean Hardware Acceleration? I tried disabling hardware decoding for MPEG4 files and that seemed to fix the issue, but I don't want to disable hardware decoding for all my files since my GPU picking up slack for my CPU is important for my hardware setup. Is there anyway to solve this? Or at least disable Hardware Acceleration just for these files?

[Luke 39644]

You could try using our new convert feature so that you can convert them to h264. otherwise these hardware decoders and encoders are not perfect yet, that's why we call the feature expiremental.

[Waldonnis 148]

mpeg4/DivX shouldn't be too hard for a modern CPU to decode, so you can probably leave hardware decoding for mpeg4 off and testing transcoding a few files to see if you can live with the load.  From past troubleshooting, I've seen issues with nVidia's mpeg4 decoder before, so it doesn't surprise me that it's having issues here.

 

I also concur with Luke that converting the problematic files may end up being the best solution in the long run (either using the convert feature in Emby or something like Handbrake)....h.264 is far better supported by playback devices these days, and I haven't seem the same problems from nVidia's h.264 hardware decoder.

I guess I'll go with converting them then, since only the one show is giving me issues, though it is 50 episodes long.
