[00:16:13 CEST] <zzlatev> another: please help me with that
[00:17:13 CEST] <furq> zzlatev: just remove -listen 1
[00:17:27 CEST] <zzlatev> only this?
[00:18:39 CEST] <zzlatev> https://pastebin.com/zwwHTuN4
[00:19:19 CEST] <zzlatev> https://pastebin.com/uNRih5mG
[00:19:22 CEST] <zzlatev> furq: check this out
[00:19:29 CEST] <furq> try it
[00:19:39 CEST] <furq> if nothing else it'll get rid of that error
[00:20:02 CEST] <zzlatev> yes, but now with different error
[00:22:45 CEST] <another> try removing the backslashes
[00:23:34 CEST] <another> unless you actually have a newline in your call
[00:24:19 CEST] <zzlatev> [hls @ 0x5617c355c900] Cannot use rename on non file protocol, this may lead to races and temporary partial files
[00:24:45 CEST] <zzlatev> now it's ok, but I can't play stream.m3u8
[00:25:02 CEST] <zzlatev> I have stream1.ts, stream2.ts, stream3.ts
[00:25:08 CEST] <zzlatev> but I can't play stream.m3u8
[00:27:20 CEST] <another> what do you mean you can't play it? how are you trying to play it?
[00:27:32 CEST] <zzlatev> VLC?
[00:28:53 CEST] <zzlatev> it's ok when I play it with ffplay
[00:29:13 CEST] <zzlatev> any idea how to write this on my web server?
[01:02:48 CEST] <another> just serve the playlist and the *.ts files as normal files
[01:14:21 CEST] <DHE> yeah just let ffmpeg save into a directory that's served by your web server, then point vlc at the URL to the m3u8 file
[01:35:52 CEST] <zzlatev> thanx
[10:49:06 CEST] <azy> what hardware do i need more for ffmpeg? converting videos resolution etc. good gpu or cpu?
[11:03:33 CEST] <azy> whats the fastest way to cut and resize-to-720p a 1080p video? currently doing: ffmpeg -ss 2:25:40 -i video.ts -filter:v scale=-1:720 -c:a copy video.mp4
[20:20:14 CEST] <DHE> ..youtube has av1-encoded videos now...
[20:20:31 CEST] <durandal_1707> old news
[20:20:43 CEST] <DHE> sorry, but it's news to me...
[20:43:13 CEST] <faLUCE> is it av1 better than h264 ?
[20:44:08 CEST] <durandal_1707> define better
[20:44:22 CEST] <faLUCE> better quality at same bitrate
[20:44:33 CEST] <durandal_1707> yes
[20:45:08 CEST] <faLUCE> so it's going to replace h264 as web standard?
[20:49:01 CEST] <cehoyos> You forgot to ask for performance...
[20:49:23 CEST] <BtbN> iirc they only use it for low res/bitrate versions?
[20:49:35 CEST] <JEEB> they have now added 720p into the mix
[20:49:39 CEST] <JEEB> but yes, it's sloooow
[20:50:40 CEST] <faLUCE> cehoyos: higher cpu usage than h264 ?
[20:52:12 CEST] <cehoyos> a tiny little more...
[20:52:22 CEST] <cehoyos> (sarcasm!)
[20:52:36 CEST] <cehoyos> But why don't you test yourself?
[20:53:03 CEST] <faLUCE> I'll do. but I wonder if this reflects on youtube videos as well or is it only for the encoding part
[20:58:30 CEST] <another> yt also has some 4k encodes in av1
[20:58:38 CEST] <rnderr> \/
[20:58:58 CEST] <durandal_1707> no qcif?
[20:59:17 CEST] <another> https://www.youtube.com/playlist?list=PLyqf6gJt7KuHBmeVzZteZUlNUQAVLwrZS https://www.youtube.com/playlist?list=PLvndfuQ5JldKMffLOhQ6pLdO0euZfq_40
[21:01:18 CEST] <another> one the second list there are videos from 144p up to 4320p
[21:01:37 CEST] <durandal_1707> 144p? for watches?
[21:02:25 CEST] <another> maybe
[21:36:38 CEST] <DHE> av1 is to h265 as h265 is to h264
[21:36:49 CEST] <DHE> or vp9 in place of h265 if you prefer
[21:37:11 CEST] <DHE> now I have to figure out how to get support into ffmpeg and mpv
[21:37:39 CEST] <DHE> also multithreaded decoding. I tried av1 during the big release announcement last year and my CPU can't QUITE keep up with realtime 1080p decoding
[21:38:17 CEST] <durandal_1707> use dav1d for AV1 decoding?
[21:38:30 CEST] <DHE> see? that's the sort of info I need to know
[21:38:38 CEST] <DHE> :)
[23:37:27 CEST] <DaniloPereira> how to enable subtitles in ffplay?
[23:51:21 CEST] <cehoyos> They are enabled by default but ffplay only supports bitmap subtitles.
[23:51:34 CEST] <cehoyos> (no ass, ssa, mov_text etc.)
