[05:49:10 CET] <while> hi
[15:27:13 CET] <LFSVeteran> with ffmpeg -f s32le -ac 2 -ar <samplerate> -i http://ip:port/stream -acodec pcm_s32le output.wav
[15:27:25 CET] <LFSVeteran> do I still need init_resampler in transcode_aac.c ?
[15:40:08 CET] <DHE> if you need to convert between formats, yes. same number of channels and same format helps, but that still leaves the sample rate in the air.
[15:40:34 CET] <LFSVeteran> samplerate stays the same
[15:41:15 CET] <furq> yeah you don't need it
[17:16:34 CET] <Mavrik> hmm, how's libx265 these days? performance-wise?
[19:41:49 CET] <digital-_-mystik> hello.. I would like to convert a DTS-HD Master Audio codec to AC3 in an mkv container. when using this command, `ffmpeg i input.mkv -c:v copy -c:a ac3 -b:a 320k /path/to/usb/output.mkv`, does the original file remain untouched and it just copies/converts to a new container while leaving the video the same?
[19:42:20 CET] <DHE> basically yes
[19:43:05 CET] <digital-_-mystik> would you say that is the fastest way to go about it without demuxing, converting the audio, remuxing, and then putting on a usb drive?
[19:43:35 CET] <DHE> that's probably fine. it's a single command that does it all in one shot
[19:43:43 CET] <digital-_-mystik> sounds goods
[19:43:48 CET] <digital-_-mystik> good*
[19:43:50 CET] <digital-_-mystik> thanks
[20:07:39 CET] <barhom> nvidia gpu's have "GPU Utilization", "nvenc Utilization" and "nvdec Utilization". I am assuming if I run yadif_cuda filter that would not really touch the nvenc/nvdec util but increase the gpu util. Am I thinking wrong?
[20:25:25 CET] <Mavrik> That's the theory, yes.
[20:27:26 CET] <furq> barhom: nvdec has its own deinterlacing stuff that's supposedly pretty good
[20:27:53 CET] <barhom> furq: Is that different from yadif_cuda?
[20:28:01 CET] <furq> yeah
[20:28:07 CET] <furq> -deint 2 -i foo iirc
