japzone 0 Posted June 27, 2018 Share Posted June 27, 2018 (edited) 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: ffmpeg-transcode-13c2ec0e-ff80-4827-b534-fd0bcc046eea.txt ffmpeg-transcode-fc23c1d9-8a80-4821-b2ec-1c32e92785c8.txtMedia Info for the file: Format : AVI Format/Info : Audio Video Interleave File size : 232 MiB Duration : 24 min 42 s Overall bit rate : 1 311 kb/s Writing library : VirtualDub build 13720/release Video ID : 0 Format : MPEG-4 Visual Format profile : Advanced Simple@L5 Format settings : BVOP2 / GMC3 Format settings, BVOP : 2 Format settings, QPel : No Format settings, GMC : 3 warppoints Format settings, Matrix : Default (H.263) Muxing mode : Packed bitstream Codec ID : XVID Codec ID/Hint : XviD Duration : 24 min 42 s Bit rate : 1 173 kb/s Width : 640 pixels Height : 480 pixels Display aspect ratio : 4:3 Frame rate : 23.976 (23976/1000) FPS Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Progressive Compression mode : Lossy Bits/(Pixel*Frame) : 0.159 Stream size : 207 MiB (90%) Writing library : XviD 1.0.2 (UTC 2004-08-29) Audio ID : 1 Format : MPEG Audio Format version : Version 1 Format profile : Layer 3 Format settings : Joint stereo / MS Stereo Mode : Joint stereo Mode extension : MS Stereo Codec ID : 55 Codec ID/Hint : MP3 Duration : 24 min 42 s Bit rate mode : Constant Bit rate : 128 kb/s Channel(s) : 2 channels Sampling rate : 48.0 kHz Compression mode : Lossy Delay relative to video : 3 s 3 ms Stream size : 22.6 MiB (10%) Alignment : Split accross interleaves Interleave, duration : 42 ms (1.00 video frame) Interleave, preload duratio : 500 ms Writing library : LAME3.95 Edited June 27, 2018 by japzone Link to comment Share on other sites More sharing options...

Luke 36997 Posted June 27, 2018 Share Posted June 27, 2018 Try turning off cuvid, it may have just had a problem with that one particular file. Thanks. Link to comment Share on other sites More sharing options...
japzone 0 Posted June 27, 2018 Author Share Posted June 27, 2018 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? Link to comment Share on other sites More sharing options...
Luke 36997 Posted June 27, 2018 Share Posted June 27, 2018 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.

Solution Waldonnis 148 Posted June 27, 2018 Solution Share Posted June 27, 2018 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. 1 Link to comment Share on other sites More sharing options...
japzone 0 Posted June 27, 2018 Author Share Posted June 27, 2018 (edited) I guess I'll go with converting them then, since only the one show is giving me issues, though it is 50 episodes long. Edited June 27, 2018 by japzone Link to comment Share on other sites More sharing options...
