MeGUI: bug reports and feature requests - Page 39

Having issues with the x264 build from the dev-server here.
The resulting video does not play correctly with ffdshow (skipping several frames, repeatable) and it cannot be muxed with MKVtoolnix.
I coded the file again with the new x264 build and again it failed.

Downgraded to x264 from stable server: File is 100% ok, muxes fine.

Any idea what's wrong with the dev-build?
Thanks

I'm having no issues with it. Working flawlessly with several encodes, muxed to MKV just fine.

Default or development ( its not mentioned )
2.. The newer builds have certainly raised the bar of encoder settings

i wanted to ask how much subme is enough if are encoding at low bit rates i mean 600 to 1000 , also how mant ref frames and bframes are sufficient ( i am concerned more about quality and less about speed but no doubt a balanced setting will be prefeered which is not very slow... )

3 .. i am unable to decide upon deblocking , sometimes 0.0 give very good results and sometimes it doesnt, i find edges horribly blurred..

regards

guys also .. after the last 2 updates i am seeing that the settings which used to give me decent quality are encoding lot of blocks and blurred edges despite good bitrate ( then before )
could some one suggest me how can i reverse all the chnges that have been made in last 2 updates ( the first had some files other than x264 build updated and the second has x264 and a few more ) after that i didnt update at all..

MeGUI has never ever checked the files. So it doesn't matter if you copy a custom build to the directoty as long as the file names are still present (x264.exe, x264_64.exe, vfw4x264.exe and avs4x264.exe).

I have forced a downgrade at the development server now. I have still no problems but there have been several reports like yours.

Use the server you like. The default / stable one should be more stable and with the development server you get the latest tools and builds.

It may be that the video is fine but your decoder can't play it properly. Try adding --weightp 0 to the custom command line.

I'm not sure if this will help, but I have been using an AMD optimized 1416 version compiled by outlaw87 over at Doom10 without any problems. My encodes are TGMC'ed DVD videos...

Here's the link to grab the build, if you guys want to try it out.

http://doom10.org/index.php?topic=26.msg1265#msg1265

My settings are simply CRF 21 with Preset "Slower", tuning Film. Nothing else.

Okay. I wrote in the x264 subforum, let's see if someone can make some light on this issue.

Just for the record, I too had issues with x264 1416. My encode would go for about an hour and then x264 would crash. It did this twice in a row so I reverted to 1400 and things worked fine again.

quantum5uicid3 · 9th February 2010, 19:45

i also have no issues with 1416. what decoder and settings are you guys using?

I'm using the latest ffdshow tryouts as decoder and these are the "usual" settings I use under MeGUI:

Code:

program --profile high --level 4.1 --preset slow --tune film
 --pass 2 --bitrate XXXX --stats ".stats" --thread-input 
--b-pyramid normal --slices 4 --vbv-bufsize 15000 --vbv-maxrate 
15000 --aud --nal-hrd --threads 4 --output "output" "input"

I'm having the exact same problem.

What x264 build did you use to fix the problem?

rapscallion · 12th February 2010, 21:03

see post # 767 above. Also the dev server will now downgrade to 1400, just click on the "update" option to see it.

I'm confused. The downgrade works for me. Maybe you have mixed up not and now?

rapscallion · 12th February 2010, 22:25

Z...that's exactly what happenned.Post edited.

thedozer · 12th February 2010, 22:32

I tried 1400 build and it does the same (skipping frames) but not as always, the best build I could find is 1376 which is in the stable update

help_me! · 13th February 2010, 11:08

I can confirm that:

Megui from development server produces videos that neither the DXVA decoder of MPC-HC nor FFDSHOW can decode properly.
Megui from stable server produces videos that play perfectly on both.

Most likely it's the newer x264 versions that are problematic.

So you have changed nothing beside the x264 build? Are the problems reproducable with 1400/1416? Please provide more information about your system (especially 32/64 bit), the source file, avs used and the megui log (command line for x264).

help_me! · 13th February 2010, 15:22

So here's what I did for you:

Uninstalled Megui, and did a fresh install of 1056.
Updated to the latest core and tools from stable server.
Encoded a video (Unrestricted DXVA - Very High Quality, preset: slower)
It plays beautifully.

Updated the x264 (only) from the development server. (I have also tested to update the core and tools, the problem is exactly the same)
Encoded the same video with the same settings.
Upon playback MPC-HC DXVA crashes, MPC-HC with FFDSHOW decoding skips tons of frames.

Both of the videos are included in the following rar: http://www.massmirror.com/a32d872045...6f8ac531b.html
The one with the underscore "_" is the problematic.

I'm using Windows 7 x64, a quad core, source file is a 291MB HFYU avi, script consists of opening the source with AviSource and converting to YV12 with ConvertToYV12.

x64 - so maybe vfw4x264.exe or x264_64.exe could be part of the problem. Please rename the file vfw4x264.exe and rename avs4x264.exe to vfw4x264.exe. Does the newly encoded file still crash? If yes, then rename x264_64.exe to something else and rename x264.exe to x264_64.exe. Does the new encode crash? Rename the original vfw4x264.exe back to vfw4x264.exe and try again. If it is still not working then delete/rename vfw4x264.exe and rename the original x264.exe back to x264.exe and try it again.

help_me! · 13th February 2010, 15:51

Tried all of the combinations.. result is always a file that crashes upon playback.

thedozer · 13th February 2010, 18:17

I'm having the same results as "help_me!" in a Win7 32bit system with a Core2Duo processor

I also encoded different types of video files like: AVI(Xvid), MP4(H264) and MKV, and I always have the same result which is skipping frames mostly at the beginning of the videos.

I only use FFDShow for decoding though.
