HEVC / x265 quicksync / hardware transcoding not working?

This only what's being requested.  What are the following lines being returned from the transcoder that show what it actually chooses to do?  If not sure feel free to post the log file and I'll take a look for you.  Feel free to PM as well.

 

My cpu is an Intel i5 7200u so it does support this. 

I added the full transcode logs for you.

No help since this isn't the server logs.  Goto settings/server/help then click the download logs button which will create a zip file with the needed files.  You'll want to do this right after trying to play a file.

 

Before doing any of this make sure "Enable Plex Media Server debug logging" is enabled and "Enable Plex Media Server verbose logging" is NOT enabled.  These settings will make sure the correct information is logged.  Both of these options are listed under ADVANCED on the /settings/server/general tab.

I attached the relevant logs "got modified when i played the movie"

Search for the Matrix.

There you go.

 

Decoding is still enabled

Stream mapping:
  Stream #0:0 -> #0:0 (hevc (hevc_qsv) -> h264 (h264_qsv))
  Stream #0:1 -> #0:1 (copy)

Sorry. I think I forgot to click Save.

I've seen this error, before. But I can't remember where, and if there was a solution. I feel like there was, but I just can't remember.

Can you try it on the command line?

Just a thought. Maybe the issue is happening because you added the command? Because in the other topic it you said it's been added to the beta server.

Same problem here.

 

Asrock j5005-itx motherboard (Intel Gemini Lake CPU onboard) and Windows 10 (emby server beta 3.4.1.14, lastest intel driver, lasted windows update).

I've tried enabling/disabling hardware acceleration for decoding but don't work in any case.

I've seen this error, before. But I can't remember where, and if there was a solution. I feel like there was, but I just can't remember.

Stream mapping:
  Stream #0:0 -> #0:0 (hevc (native) -> h264 (h264_qsv))
  Stream #0:1 -> #0:1 (copy)
Press [q] to stop, [?] for help
[h264_qsv @ 0000015197a11480] Current pixel format is unsupported
[h264_qsv @ 0000015197a11480] some encoding parameters are not supported by the QSV runtime. Please double check the input parameters.
Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

Conversion failed!

 

If it's throwing an error about the current pixel format being unsupported, it's usually because it thinks the hardware/driver can't support the pixel format selected by get_format() with that encoder choice.  In the case of yuv420p10le videos, it's probably choosing p010le...and I don't think the h.264 encoder can deal with 10bit input/output like that (ffmpeg seems to think it's okay, but MFX is not happy).  You can specify a pix_fmt that (at least it thinks) is supported by the hardware and it should work (you can try nv12 as a test).  Even if it's not a 10bit source, pix_fmt autoselection has gone wrong in the past, so this may just be another case of that and you'd still have to specify one.  The only way to tell what's going on there is to run ffmpeg manually and increasing the loglevel (debug should be fine).

 

Curious that Plex is using DXVA2.  Last I saw, ffmpeg still relied on D3D9 to provide the DXVA2 context and, in the words of Microsoft themselves:

Direct3D 9 is not supported in the context of a Windows service.  Direct3D 9 is only supported when executed on an interactive desktop.

 

I'm wondering if they're forcing a d3d11 context instead (-hwaccel d3d11va), which doesn't have the same limitation....but it doesn't make sense that it would be logged as dxva2.  I guess they could be running the server within a context that includes interactive desktop access.

I was wondering if it was a driver, issue. Not interacting with ffmpeg, correctly?

 

It's always possible, but I'm pretty sure the API has been stable for a long while...a bug in ffmpeg *or* the driver itself would be far more likely.  ffmpeg implements their hardware en/decoders very generically, meaning they don't query hardware to determine capabilities.  Rather, they rely on the driver/libMFX to do the right thing (either work or error out), so it may be that it's trying the logically-appropriate pixel format that *could* work on some hardware and just don't have the smarts to "fall back" to another pix_fmt when libMFX chokes on what it was given.

 

Side note: another QSV maintainer from Intel (Zhong Li) was recently added to the list in the ffmpeg repo, although he's been involved for months now.

I've yet to find a single HEVC sample that does work with Quick Sync transcoding.

 

If anyone can find a HEVC sample that works - please share! I would like to check the encoding settings.

 

 

@@Luke - it would be awesome if we could get our hands on a HEVC sample that does work, just for trial and error. Could you share a sample that works with your setup?

Intel's HEVC support varies per generation, so you have to compared to similar cpu/GPU...

Yes, but currently it doesn't work independent of what GPU you have. I don't think that's an issue though if you have HD5xx or HD6xx - it should run on both. 

 

It does seem to be working in the Plex beta for @@aahmyu, and it does work with FFMPEG for me (I've only tried the daily build so far though, not latest stable).

What command line are you testing with?

Morning. Any update on this. Will we see the fix in next beta? I'd happily test if you give a compiled "pre-beta" version.

What command line were you testing it with externally?

I never tested with command lines. I only tested with Plex and posted all the logs to help you guys debug the issue. If you give me a command example I can do some testing for you. I really want this to work.

 

Edit: just tried the benchmark command from this page https://trac.ffmpeg.org/wiki/HWAccelIntro#DXVA2

ffmpeg -hwaccel dxva2 -threads 1 -i INPUT -f null - -benchmark

And it works fine. So maybe you need to enable dxva2 or something? because maybe the qsv is broken. I think plex is using it as well.

Read my post about dxva2 above.  I know Luke tried using the dxva2 hwaccel before (at my urging, actually) and it didn't work out well for a few reasons that neither one of us foresaw.  Because Plex is implemented differently, it's possible that they could use dxva2 and Emby couldn't, even though Plex's transcoder is basically a stripped-down/modified ffmpeg.  Basically, running ffmpeg from a command prompt is different than running it in a service context (the latter being more restricted and not actually "attached" to an interactive desktop).  There are other wrinkles in the case of ffmpeg's QuickSync implementation as well that I won't get into, but do cause it to be a bit more temperamental than other hardware wrappers.

 

IMO, hwaccels should be revisited at some point since there has been more work done on them in ffmpeg since the last test...and I think hardware de/encoding is going to be practically required by people without ridiculously powerful CPUs now that HEVC and 2160p sources are becoming more prevalent.  I'm not sure, however, if dxva2 is the best hwaccel to use at this point because of the limitation mentioned above (among other things).  I do wonder why Plex chose it, but they do a lot of things that puzzle me...
