[19:14:59 CET] <cone-384> ffmpeg 03Paul B Mahol 07master:662120f2b27d: avfilter/vf_convolution: use sqrtf as its faster
[22:28:23 CET] <philipl> BtbN: https://devtalk.nvidia.com/default/topic/1042459/video-codec-sdk/nvdec-in-ffmpeg-cuvid-drops-frames-when-using-deinterlacing-deint-2-/1
[22:30:02 CET] <BtbN> philipl, the issue is ffmpeg.c not supporting a decoder changing the framerate
[22:30:53 CET] <philipl> I thought forcing the frame rate on the command line fixed it.
[22:30:58 CET] <philipl> People in the thread tried that
[22:31:07 CET] <philipl> It apparently used to work and now has problems
[22:31:09 CET] <JEEB> time base, maybe
[22:31:10 CET] <BtbN> It does in very simple cases
[22:31:10 CET] <cone-384> ffmpeg 03Marton Balint 07master:aecd63b92681: avfilter/af_afade: fix duration maximum
[22:31:27 CET] <BtbN> And is not a supported mode of operation, so it aparently broke at some point
[22:34:31 CET] <BtbN> cuvid does all it can, it halves the timebase, and fixes the fps
[22:34:42 CET] <BtbN> The rest of ffmpeg just isn't expecting a decoder to do that.
[22:35:06 CET] <JEEB> yea, ffmpeg.c is very static in various ways
[22:44:21 CET] <philipl> BtbN: Ok. So maybe I should just tell them it's a bonus if it works and not to rely on it.
[22:45:11 CET] <cone-384> ffmpeg 03Mark Harris 07release/4.1:fed94c2f22fc: avfilter/vf_fade: fix start/duration max value
[22:45:11 CET] <cone-384> ffmpeg 03Marton Balint 07release/4.1:bb01cd3cc01c: avfilter/af_afade: fix duration maximum
[22:45:15 CET] <BtbN> It works fine. Just not with ffmpeg.c
[22:45:48 CET] <BtbN> It's also not something that's easily fixed, but a major Design issue.
[22:47:01 CET] <BtbN> Like, it initializes the whole filter chain with the framerate/timebase the demuxer reports, way before consulting with the decoder
[22:47:01 CET] <philipl> I mean it's not to be relied on with ffmpeg.c
[22:47:04 CET] <philipl> I know it works fine in general.
