sv3nno 2 Posted May 27, 2020 Share Posted May 27, 2020 In the not working example you've selected PGS subtitles and as a result they have to burned in with transcoding. To make it a more equivalent comparison, try turning the subtitles off prior to playback. Please see if that helps. Thanks. Yes sir! I tried 5 minutes of playback with no subtitles. The result is really horrible, green frames/chopped frames, seems like its jumping back and forth between parts in the movie too. FFmpeg log is attached. not working file ffmpeg log 2.txt Link to comment Share on other sites More sharing options...
D34DC3N73R 18 Posted June 1, 2020 Author Share Posted June 1, 2020 Here are a couple more logs, one from my remote server (intel qsv - VAAPI) and one from my local server (p2000 - NVDEC/NVENC). As you can see, this happens with a remux as well as a transcode. ffmpeg-remux-a41d6c43-adc7-4ecf-b91f-f2e7bad06426_1.txt ffmpeg-remux-4c2822a1-0ed1-4e9d-9d84-5780b01d43d2_1.txt Link to comment Share on other sites More sharing options...
softworkz 3324 Posted September 12, 2020 Share Posted September 12, 2020 @D34DC3N73R The last two logs show software encoding and decoding. When even that doesn't work, then there's most likely something wrong with the file. Link to comment Share on other sites More sharing options...
D34DC3N73R 18 Posted September 12, 2020 Author Share Posted September 12, 2020 @softworkz It's possible, but it plays fine in VLC locally, and plays fine in plex. Link to comment Share on other sites More sharing options...

OK, no - then ffmpeg should do it as well (when sw de- and en-coding).. Let me re-think this tomorrow.. Link to comment Share on other sites More sharing options...
vdatanet 1549 Posted September 12, 2020 Share Posted September 12, 2020 Maybe it's related to this? But I have to say I've only seen that remuxing not transcoding. Link to comment Share on other sites More sharing options...
softworkz 3324 Posted November 21, 2020 Share Posted November 21, 2020 If you would be willing to try a beta version - today's beta includes a new decoder for testing that might fix this issue. It is called NVDEC.Ex and it is disabled by default: You'd need to enable it and move it to the top. Link to comment Share on other sites More sharing options...
grbharati 2 Posted December 1, 2020 Share Posted December 1, 2020 (edited) Hi Softworkz: I can confirm that enabling NVDEC.Ex for my Quadro in v4.6.0.6 beta fixed the green glitch for transcoding 4k to 1080p. I was having green glitch screen in lots of 4k movies when transcoded to 1080p clients. I tested almost all of the movies I recall with the NVDEC.Ex and now I no longer see this green glitch issue in any of the movies so far. Transcoding is using: H.265 (HEVC)-NVENC/DEC to H.264(AVC)-NVENC/DEC. Nice work and thank you. Edited December 1, 2020 by grbharati Link to comment Share on other sites More sharing options...

sv3nno 2 Posted December 16, 2020 Share Posted December 16, 2020 I have tested the new decoder in 4.5.4.0. This has solved the issue for me as well. Thanks :) 1 Link to comment Share on other sites More sharing options...
