[00:11:00 CEST] <void09> kepstin: I'm thinking another strategy might work.. if blurays have keyframes at 1-2 seconds as you say, then when a scene change is detected, if that frame is not a keyframe (very likely, 1/24 or 1/48 chance for it to be a keyframe), then loslessly compress that part until the next keyframe arrives, and then cut at the keyframe, until the next scene change, and aagain, append the last part until a scene
[00:11:03 CEST] <void09> change losslessly comprssed, if not a keyframe.
[00:11:56 CEST] <void09> but this not perfect for scenarios where the scene changes just for a split second and the encoder does not do a new keyframe. this might happen i guess, i don't know much about those algorithms
[02:13:05 CEST] <noahmg123> I'm trying to pull a security camera stream off of a URL. I can get the video just fine (in H264 format), however, I'm having trouble pulling down the audio stream with it.
[02:17:04 CEST] <dongs> oh hey
[02:17:15 CEST] <dongs> aac channelConfiguration() of 13 is actaully valid
[02:17:23 CEST] <dongs> so maybe my 22ch audio isnt borked as much as I thought
[02:17:48 CEST] <dongs> 13: 22.2ch (3/3/3-5/2/3-3/0/0+2)
[02:22:39 CEST] <dongs> is trac.ffmpeg dead
[02:50:48 CEST] <electrotoscope> it's been struggling the last few days, but if you keep refreshing it should work
[02:58:22 CEST] <another> void09: https://github.com/Breakthrough/PySceneDetect might be something to look into
[02:58:57 CEST] <another> also, iirc the segment muxer always splits on keyframes
[02:59:06 CEST] <another> see documentation
[13:50:28 CEST] <zzlatev> hey guys, can you help me with something
[13:50:35 CEST] <zzlatev> 2019-06-08 14:41:15.655 spawn: Executing "/usr/bin/ffmpeg
[13:50:44 CEST] <zzlatev> 2019-06-08 14:41:15.686 spawn: Error splitting the argument list: Option not found
[13:50:50 CEST] <zzlatev> https://pastebin.com/MXy4RCQG
[13:50:59 CEST] <zzlatev> this is weird, because it works in another tvheadend
[20:10:59 CEST] <kepstin> zzlatev: nothing obvious there. The '-tune' option is of course useless because you're not using any encoder it could apply to, but I don't think that's a fatal error?
[20:27:08 CEST] <another> set loglevle to debug and see what comes up
[21:21:54 CEST] <lagzilla> I'm trying to convert a file with ```ffmpeg -i audio.mp3 -c:a libvorbis -q:a 4 --map_metadata 0 file.ogg``` but I keep getting error Unrecognized option '-map_metadata'. But I still see the option available in the latest docs https://ffmpeg.org/ffmpeg.html
[21:23:03 CEST] <another> which version are you running?
[21:23:38 CEST] <another> oh, wait. you're using double dashes
[21:24:21 CEST] <lagzilla> oh
[21:24:25 CEST] <lagzilla> oops lol
[21:24:27 CEST] <lagzilla> thanks
[21:25:38 CEST] <another> super secret pro tip: reading error messages dilligently :)
[21:26:17 CEST] <another> would've saved me countless hours of debugging...
