[17:13:45 CEST] <tdjones> atomnuker: I'm currently working on ironing out my final changes for the vorbis encoder. Do you have anything that you want included with the "official" submission for GsoC?
[17:14:39 CEST] <tdjones> I've just written a blog post that discusses what changes I made and includes links to the mailing list and git commit hashes, but if you want anything additional I can try to put it in
[17:17:13 CEST] <atomnuker> tdjones: you can still change your sumbission until the 29th, right?
[17:21:50 CEST] <tdjones> Yeah, that's the final submission deadline
[17:22:25 CEST] <atomnuker> cool, submit what you have tomorrow and we'll get it polished
[17:23:34 CEST] <tdjones> Ok, I tried implementing real basic bit-rate control that just shifted the quality up and down based on projected needs. Similar to how AAC does, but without multiple passes for each frame.
[17:23:42 CEST] <tdjones> It didn't really remove the clicking effect
[17:25:52 CEST] <atomnuker> so can you set the bitrate and the encoder would keep it around the same?
[17:30:25 CEST] <tdjones> Roughly. From what I understand, there isn't really a mechanism for adjusting quality dynamically during floor or residue construction, so it ends up being reactive to earlier changes rather than predictive
[17:31:35 CEST] <tdjones> The libvorbis encoder actually constructs multiple floors since they are relatively cheap and chooses the correct one after more information is available
[17:32:30 CEST] <atomnuker> that's alright, it needs not keep the bitrate exactly, variations of up to 2x (according to the libopus school of encoder writing) are acceptible
[18:14:12 CEST] <cone-480> ffmpeg 03Paul B Mahol 07master:f5361ee56f21: avfilter/vf_pseudocolor: add support for some subsampled formats
