DS920+ Software Transcoding

[DJX 18]

Can I get some help please?

I paid for Premiere but still the Hardware transcoding does not work. If only does software.

I have a Synology DS920+ with DSM 6.2.4-25556

INTEL Celeron J4125

 

Logs attached from an attempt to watch a video. My emby dash showed it was doing software transcoding.

@DJX I've split your posting into a new topic.

Just saw this.  @DJX are you still having a problem?

I have a DS920+ as well and can help you if needed.

Thanks

May need @softworkz for this.

@DJX - What kind of video is this, where did you get it from? From a smartphone?

The point is this:

 

It seems that ffmpeg has some automatism to insert a transpose filter to apply the display matrix (90° rotation). The transpose filter is a software filter, that's why its insertion fails in the initial transcoding pipeline (because it's a pure hw pipeline).

In case of the subsequent (sw-fallback-)attempt, its insertion works as it's all sw processing.

To be honest: this is the first time that I'm seeing this, and I don't have a plan yet for dealing with it.
My very first thought is more like: nice that it's getting handled by sw fallback at least..

Yes, my videos are 4K taken from a Samsung s21+.

I've just tried the encoding/decoding again and ticked VAAPI for h264/265 for both. This time the dashboard shows it working correctly with VAAPI>VAAPI.

So I think its working fine for me now!

Thanks!

Including the orientation?

When I'm on 4g the quality goes to 1080p because of the auto setting and the video is stretched landscape on my phone. If I change the quality to 4k or direct playing when on my network then I have to physically turn my phone in my hand and the video is displayed smaller

Ideally it would play it portrait and full screen like the original on my phone I guess?

OK so that means when direct playing, the android video player isn't auto-rotating. So that's something that needs to be looked at. Thanks.
