[16:22:38 CEST] <kepstin> huh, regarding ticket #7939, I have a half finished patch to improve the framerate/timebase selection in the concat filter, I should look at that again :/

[16:43:40 CEST] <Anonffmpeg> Hi fella
[16:43:42 CEST] <Anonffmpeg> Hi. Have a particular question: Have a program that generates continously a file, named "file.jpg" every millisecond for 10 seconds. Need that ffmpeg inputs(-i) the file continously and provide a "video.mp4" that is being "streamed"(keeps growing).
[16:45:29 CEST] <gnafu> Anonffmpeg: You might be better off asking in #ffmpeg, as this channel is specifically for ffmpeg development.
[16:45:34 CEST] <Anonffmpeg> Wrong channel
[16:45:52 CEST] <Anonffmpeg> Thanks!
[23:25:13 CEST] <darkapex> what's the difference between cuvid and nvdec here https://trac.ffmpeg.org/wiki/HWAccelIntro#NVDECCUVID ? I see that nvdec is a hwaccel module, while cuvid is a full decoder. but what does that mean internally in terms of host-device memory copying? 
[23:26:11 CEST] <darkapex> also from what i could see, lavc/cuviddec.c does not seem to use the functions in lavc/nvdec* is that correct?
[23:26:30 CEST] <BtbN> One uses ffmpeg parser, one nvidia one
[23:27:41 CEST] <BtbN> cuvid can also make use of some special features of nvdec like scale/crop/deint, since it's a standalone decoder and can change frame size
[23:31:52 CEST] <darkapex> BtbN: oh I see thanks! so CUVID passes bitstream as-is to the NVIDIA driver i believe? but NVDEC being a HWACCEL module uses ffmpeg's parsing and just passes individual frames to the driver right?
[23:36:49 CEST] <darkapex> ok yeah this clarifies it https://github.com/FFmpeg/FFmpeg/commit/ae5046e492 thanks!
