[09:50] <ubitux> 09:23:17 <+smarter> BBB, lu_zero: someone made a "human readable translation" of the hevc spec: http://www.f265.org/f265/static/txt/h265_companion.html
[09:50] <ubitux> (might interest some ppl here too)
[10:59] <j-b> Morning
[11:03] <iive> evening :)
[13:40] <BBB> and yes there's indeed too many hevc encoders
[13:40] <BBB> can someone do a quality comparison or make a list of reasons why you'd use/develop any one of them?
[13:41] <BBB> seems hopeless atm
[13:43] <mraulet> BBB ready for asm review?
[13:44] <pross-au> BBB: why is it we have N encoders, and much smaller N decoders?
[13:45] <mraulet> already 2 decoders :-) which I think is already too much
[13:45] <mraulet> and 4 encoders
[13:45] <JEEBsv> basically x265 is still way in the lead regarding features and proper rate control, and everything else then has other positive things, like f265 having zomg docs
[13:46] <pross-au> hypothesis: nobody will pay for decoder
[13:46] <smarter> the kvazaar developers are nice, but it's the only GPL one
[13:46] <JEEBsv> yeah, the kvazaar folk are nice
[13:48] <mraulet> pross-au: well it is an alternative to set top boxes at the moment so ...
[13:58] <BBB> mraulet: yeah always
[13:58] <BBB> pross-au: decoders aren't ... interesting
[13:58] <BBB> pross-au: once ffmpeg absorbs one, the others die
[13:58] <BBB> pross-au: encoders have a more elaborate life-cycle, so they're more interesting
[13:58] <BBB> and yes the pay also helps/hurts
[13:58] <BBB> I mean x264 did really well for themselves there
[14:39] <Compn> hmm
[14:40] <Compn> so the ffmpeg_*.c files dont really have copyright in them? we arent doing that anymore ?
[14:40] <Compn> duplicated author copyrights ?
[14:47] <Compn> i guess ffmpeg never did that, i was thinking of mplayer :)
[14:55] <pross-au> when all decoders are done, ffmpeg can start to absorb encoders too
[15:02] <Compn> ffmpeg has to absorb imagemagick and dcraw :)
[15:04] <pross-au> ciao
[15:22] <cone-701> ffmpeg.git 03Michael Niedermayer 07master:6a0b5e34763c: avcodec/mpegvideo: fix null pointer dereference
[15:53] <zidanne> hi again guys (:
[15:54] <zidanne> in one of my implementations, ffmpeg resolves aac with mChannelsPerFrame = 2, in another implementation of mine mChannelsPerFrame = 1. I couldn't figure out what's causing it (: Do you have any ideas? (it basically only sees 1 channel instead of 2, which is wrong.)
[15:55] <thardin> are they using the same version of ffmpeg?
[15:59] <zidanne> Yes they are :-/
[16:00] <zidanne> : - |
[16:00] <J_Darnley> :  -  \
[16:03] <zidanne> Since the channel number is incorrect, audio is like a cassette player which's battery is about to die (:
[16:07] <Compn> different probe size ?
[16:07] <Compn> but thats strange it shouldnt affect that
[16:07] <nevcairiel> sounds like you may be missing extradata or other initialization data
[16:07] <thardin> diff all structs you send into libav*
[16:26] <cone-701> ffmpeg.git 03Enrique Arizón Benito 07master:5c08ae4f3728: segment: Add an option to prepend a string to the list entries
[16:26] <cone-701> ffmpeg.git 03Michael Niedermayer 07master:fd601ba6b1c6: Merge commit '5c08ae4f37281441188447cd04dcaf7cd7ce031f'
[16:28] <zidanne> I check channel_layout and it unfortunately AV_CH_LAYOUT_MONO. I checked probe size they are same, I made it big too but nothing changed. When I manually assuma the channel number is 2, audio plays perfectly. But if I leave it to pcodecctx->mChannelsPerFrame (which is 1), audio slows down as expected
[16:28] <zidanne> so, I must be doing something that breaks ffmpeg and ffmpeg detect wrong number of channels
[16:38] <zidanne> I found something
[16:38] <zidanne> pCodecCtx->channels = 1, but, decoded_frame.channels = 2, is this normal?
[16:39] <nevcairiel> ideally you should always use the frame properties, things like this can happen, although its probably a bug when they do
[16:43] <J_Darnley> You said this was AAC.  Is the the kind of AAC with its "strange" stereo encoding mode?
[16:44] <zidanne> J_Darnley: rtmp://stream.n2.noc.com.tr/live/radyoa.stream
[16:46] <J_Darnley> Hmm, ffprobe doesn't say.
[16:56] <zidanne> it seems like it is AAC+SBR
[16:56] <nevcairiel> SBR only messes with sample rate, not number of channels
[17:03] <zidanne> ok guys, you are right. I think I found the problem. I was checking codecCtx->channels before the first avcodec_decode_audio4. When I debug, after the decoding it updates codecCtx->channels to 2 correctly.
