Patches should be submitted to the ffmpeg-devel mailing list and not this bug tracker. I will just mention how much bigger the ffmpeg file is, compared to oJBa.mlp. Then decode this sample, encoded with git-master ffmpeg (48k has the same artefacts): Īnd compare how ffmpeg decodes it with how Plex and LG C9 does, here is it (16 bit has the same artefacts, artefacts start at 00:01:02): ĭolby Media Encoder at least appears to be without artefacts, alas it cannot encode 44.1, so I did on 16 bits ffmpeg.exe -i "sample.thd" -ar 48000 48.wav ( ) and encoded with Dolby Media Encoder: How to reproduce: buy LG C9 or use instruction to get EAE.exe decoder. Official encoder does not have such artefacts (DEE or Dolby media encoder). I would imagine drp.exe (Dolby reference player) will also have those. Now it can thanks to Paul's fixes, so it is now obvious it has same artefacts SAME AS in LG C9 HW decoder, bitstreamed by Lavfilters. ![]() But that is an illusion: for a very long time Plex Transcoder.exe with EasyAudioEncoder.exe decoder could not decode produced by ffmpeg thd. ![]() ![]() Summary of the bug: first of all there is no bug with our ffmpeg decoder, it is all 24 bits lossless and gapless.
