[00:39:45 CET] <kevinnn> JEEB: hey are you still around? [00:41:55 CET] <JEEB> kevinnn: no :P I am finishing up as it's almost 2am and getting some sleep [00:42:25 CET] <kevinnn> JEEB: do you know anything about rfc3984? [00:42:43 CET] <kevinnn> looks like live555 want's the outgoing packets to follow these standards [00:42:55 CET] <kevinnn> but the reading for it looks dense... [00:47:49 CET] <kevinnn> can anyone give me a break down of what exactly is inside of p_payload inside of x264_nal_t? [01:47:10 CET] <kandinski> I'm using ffmpeg to decode rw bayer8 frames from a camera, and I want to output it to localhost with minimal latency. Size is not a problem, because we won't be sending it over a network. What's the recommended output encoder/format in this case? [01:57:38 CET] <kandinski> Answering my own question: bmp codec seems to be doing the trick. [03:59:00 CET] <ricemuffinball> i have a video file that was separated into 2, how do i join them back together? [04:25:30 CET] <friendofafriend> ricemuffinball: concat. [04:26:10 CET] <ricemuffinball> you mean this? ffmpeg -safe 0 -f concat -i list.txt -c copy output.mp4 [04:26:47 CET] <ricemuffinball> that creates corrupted file [06:54:54 CET] <ricemuffinball> i have a video file that was separated into 2, how do i join them back together? [06:58:06 CET] <TheAMM> You'll have to elaborate a bit [07:14:39 CET] <ricemuffinball> i have a video file that was separated into 2, how do i join them back together into one file? [07:20:40 CET] <pink_mist> technically adding "into one file" is elaborating ... slightly [12:31:00 CET] <vtorri> hello [12:31:18 CET] <vtorri> i am trying to compile ffmpeg with theora support [12:31:30 CET] <vtorri> i've installe theora from sources [12:31:57 CET] <vtorri> i've forgotten to say that it's on Windows using MSYS2 + mingw-w64 [12:32:15 CET] <vtorri> so i passed --enable-libtheora [12:32:17 CET] <vtorri> i get : [12:32:32 CET] <vtorri> ERROR: libtheora not found [12:33:57 CET] <vtorri> from config.log the problem is link error [12:34:30 CET] <vtorri> E:/Documents/programmes_x64/msys2/mingw32/bin/../lib/gcc/i686-w64-mingw32/7.4.0/../../../../i686-w64-mingw32/bin/ld.exe: cannot find -ltheoraenc [12:34:46 CET] <vtorri> same for -ltheoradec and -logg [12:35:13 CET] <vtorri> why isn't pkg-config used for theora ? this package provide it [12:56:30 CET] <DHE> from a linux standpoint, it is but by default a source-compiled package puts its pkg-config data into /usr/local/lib/pkg-config which isn't searched by pkg-config by default. On linux I would "export PKG_CONFIG_PATH=/usr/local/lib/pkg-config" (or whatever is suitable to your shell) and try again [12:56:46 CET] <DHE> translating that to mingw is an exercise for the user... :/ [12:57:25 CET] <JEEB> cross-compilation you usually want PKG_CONFIG_LIBDIR [12:57:31 CET] <JEEB> which overrides the full path [12:57:35 CET] <JEEB> PKG_CONFIG_PATH appends [12:58:02 CET] <JEEB> right, it's mingw-w64 on msys2 which masquerades as not cross-compiling [12:58:05 CET] <JEEB> then PKG_CONFIG_PATH [13:04:36 CET] <ossifrage> So I can do "ffmpeg .... out.ppm" but "ffmpeg .... -f ppm -" doesn't work? [13:07:51 CET] <ossifrage> Requested output format 'ppm' is not a suitable output format [13:10:26 CET] <furq> ossifrage: -f image2pipe -c:v ppm - [13:11:33 CET] <ossifrage> furq, thanks! [13:13:45 CET] <ossifrage> Sometimes I really love bash: https://termbin.com/pfrp [13:16:08 CET] <ossifrage> Every time the encoder hits an IDR frame it dumps the h.26[45] elementary stream to /tmp and you can view it with ffplay :-) [13:29:28 CET] <ossifrage> I wonder how hard it would be to encapsulate a single IVOP into something you could convince chrome/firefox to display as a still image [13:30:22 CET] <ossifrage> (without any javascript hick, just the image from the urlbar) [14:31:54 CET] <vtorri> JEEB DHE : actually, theora is not detected with pkg-config [14:32:10 CET] <vtorri> JEEB DHE : in the configure script : [14:32:29 CET] <vtorri> enabled libtheora && require libtheora theora/theoraenc.h th_info_init -ltheoraenc -ltheoradec -logg [14:32:46 CET] <vtorri> while for a lib detected with pkg-config : [14:33:05 CET] <vtorri> enabled libtesseract && require_pkg_config libtesseract tesseract tesseract/capi.h TessBaseAPICreate [14:34:00 CET] <vtorri> it's not a problem, i have set CPPFLAGS and LDFLAGS so that theora lib is detected, but it is strange that pkg-config is not used [14:35:03 CET] <vtorri> vorbis and speex are detected with pkg-config, but theora is not [15:04:33 CET] <JEEB> vtorri: ok, that sounds like an easy add then [15:04:49 CET] <JEEB> I've added zlib before because I got tired of adding manual flags with cross-compilation :V [15:04:55 CET] <JEEB> I just never used theora myslef [15:30:17 CET] <vtorri> JEEB for what it worth : i have written a package installer (not manager) which compiles from sources all the libraries that are needed for the project i'm involved in. [15:30:36 CET] <vtorri> JEEB and i'm trying to figure out what are the needed libraries for ffmpeg [15:31:16 CET] <vtorri> at first i haven't understood why theora was not detected while the other lib with pc files were [19:31:11 CET] <brimestone> Hey guys, I have a MacPro Ivybridge, it has 2 AMD FirePro500... is there any hwaccels I could use on this hardware? When I do -hwaccels all I get is videotoolbox [19:36:07 CET] <DHE> from a pure hardware standpoint, ivybridge MIGHT have quicksync support, but it varies by the exact CPU [19:36:33 CET] <brimestone> Im hoping to let the GPU handle so I can use the CPU for something else [19:37:22 CET] <DHE> quicksync is additional hardware in the CPU. I think it's related to onboard graphics but don't quote me on that. [19:37:39 CET] <JEEB> it's usually on the GPU side of the CPU [19:37:46 CET] <JEEB> not really much more than that [19:37:50 CET] <JEEB> it's a separate block within that [19:39:44 CET] <DHE> if it's a laptop, there might be onboard graphics even if you have a discrete GPU. that was a thing back then, right? [19:47:32 CET] <kepstin> this is a mac pro tho, it might have one of the xeons with igpu disabled. You'd have to check specific processor model. [19:49:36 CET] <brimestone> How about vaapi will that help me? [19:52:13 CET] <Hello71> trash can, lol [19:52:20 CET] <brimestone> HAHAHAHA [20:05:21 CET] <brimestone> what hardware would be best for transcoding to h264, h264, dnxhd from ProRes, h264, xdcam sources [23:08:42 CET] <grungies1138> Hello guys. Can anyone here offer any alsa support? [23:08:57 CET] <grungies1138> Or is there another room I should look into? [23:09:45 CET] <JEEB> if you are just developing something using alsa, then I would recommend one of the alsa support channels [23:11:26 CET] <grungies1138> thanks [00:00:00 CET] --- Wed Feb 27 2019
