oh yeah i've had that too, but forgot to tell you. i was pretty confused when it happened

Has anyone tried this with hashd.tv? I figure it could work since it uses the same rtmp and stream key mumbo jumbo, but it didn't in the brief time I tried.

yeah streaming to hashd worked. i used this url:

Code:

rtmp://ingest-ams1.hashd.tv/live/djs?key=abc123streamkeygoeshereabc123

HELLO!

Unless you're in Europe I don't imagine the Amsterdam ingest is the best bet. Don't they have one in Dallas?

oh yeah, yeah you can change that. im in sweden so i used that one. should work the same with dallas.
for your convenience:

Code:

Dallas:
rtmp://ingest-dal1.hashd.tv/live/USERNAME?key=YOURKEY

Amsterdam:
rtmp://ingest-ams1.hashd.tv/live/USERNAME?key=YOURKEY

your stream key can be obtained here: http://hashd.tv/settings/streams (click Details under the stream you want).
then just throw that into kumari.

HELLO!

OK so I'm going to go ahead and use Kumari for all my future Twitch and Hashd stuff. That just leaves Nico.

Nico's catch is the 384kb/s cap for audio + video.

EDIT 3 weeks later Smiley

Now that I've been streaming exclusively with Kumari for a while, I've learned something. Twitch is apparently really really having trouble pushing out data to some people (not surprising I guess judging by their shameless begging for free peering), and so for some people a 720p stream is a slideshow.

An option to scale down the stream would be great.

Is Kumari doing CBR?

ah, that's cute. well, i guess i can't say anything.

as for cbr, if it's not then it should be. wild bitrate fluctuations are dumb for streaming. from the ffmpeg code:

Code:

        avcodec_get_context_defaults3(c, *codec);
        c->codec_id = codec_id;

        c->bit_rate = video_bitrate_kbit * 1000;
//        c->rc_max_rate = 1024000;
//        c->rc_buffer_size = 10 * 1000 * 1000;
        c->width    = video_width;
        c->height   = video_height;
        c->time_base.num = 1000;
        c->time_base.den = (int)(video_framerate * 1000.0);
        video_frame_time_ms = ((double)c->time_base.num / (double)c->time_base.den) * 1000.0;
        c->gop_size      = 60; /* emit one intra frame every 60 frames at most */
        c->pix_fmt       = AV_PIX_FMT_YUV420P;
        c->thread_count = 0;

note that those two rate control settings are commented out. i remember playing around with them and not being impressed, but i can't remember any details. from x264 and ffmpeg when streaming starts:

looks like i may need to add min and max bitrate with a buffer size. well, i doubt the fluctuations are severe right now. maybe for certain games like old school resident evil when there is a big difference between normal gameplay and fmv cutscenes.

Just curious, would it be a lot of work to support Syphon? It would enable quick support for CamTwist video in Kumari (although CT has its own issues, but meh). Syphon seems to produce excellent results with almost no additional CPU loss from my testing.

nate

2013-08-14 11:29:08 am

i took a look at it. it would be the first time i've integrated objective-c into one of my projects but that's not really a big deal. the api seems simple enough. only thing i don't know right now is how to access the pixel data of a specific gl texture given its id. i assume it's some kind of opengl downloading function analogous to uploading a texture for display, just in reverse. the reason it's not already like that is this syphon library is mainly intended for compositing and/or display and not for things that need access to the picture data on the cpu side (such as a streaming app). it's probably not a big deal if you're not using a lot of other programs subscribing to the same stream but it would have been better for them to provide a way for the client to tell the server "also send a pointer to the pixel data in cpu memory". so that way the copy back out of vram would only happen once. but like i said, probably not a big deal if kumari is the only app doing that.

HELLO!

I guess that answers my question, that I keep remembering while I'm streaming but forget at other times, as to whether you'd accept OS-specific code in the form of a patch to allow disabling the screen saver while streaming/recording.

Quote from Some Twitch User:

Are there any planned solutions for mac users? I understand you're working with the most popular Windows software to provide solutions, are you working with supporting Wirecast or FMLE? Neither of those have CBR.

Quote from Jared Rea:

I brought that up this morning. As someone who started streaming by forcing CamTwist to make sweet love to FMLE, I know that it can be difficult to stream on Mac's. We'll see what's possible from our end.

Would you mind if I brought Kumari to his attention? Seems like all Twitch is aware of is FMLE and Wirecast. I'd like them to be aware of the 2 newer options on the off chance something good will come of it.

no lol, go for it. it's a bit embarrassing because it's fucking alpha 1 but i will eventually come back around to it.

Well Twitch says my stream quality is Excellent. So it's apparently CBR enough for them.

HELLO!

Dumb question: What libraries and versions are required to build this?

I got as far as getting the thing to build with Qt 5, which mean adding some Widgets includes, and changing the deprecated QDesktopServices::storageLocation(QDesktopServices::DesktopLocation) to QStandardPaths::writableLocation(QStandardPaths::DesktopLocation)

Some searching for missing headers it balked about caused me to go grab the latest ffmpeg, then edited the project file to find my /usr/local/ffmpeg. But I'm still missing stuff:

Code:

clang: error: no such file or directory: '/usr/local/ffmpeg/lib/libpostproc.a'
clang: error: no such file or directory: '/usr/local/ffmpeg/lib/libmp3lame.a'
clang: error: no such file or directory: '/usr/local/ffmpeg/lib/libfdk-aac.a'
clang: error: no such file or directory: '/usr/local/ffmpeg/lib/libx264.a'

I'm guessing the latter three are separate libraries, but my reading suggests libpostproc is supposed to be part of ffmpeg. Is this a version thing? A configuration thing?

thanks. Here I just wanted to hack in something to scale down my stream, since Twitch really doesn't like serving 720p to everyone. Smiley

Also I wanted to make the dang thing turn off the screen saver while streaming.

I'll read and bang on it some but if you have any suggestions...

Also everything I'm doing I'm going ahead and putting up here: https://github.com/stevensmedia/kumari

definitely looks like an image format error. i have alignment problems with rgb888 (the 24-bit format) all the time. maybe try changing to one of the rgb32 ones. don't forget to change where the format appears in ffmpeg-ese. should be like AV_PIX_FMT_something.

HELLO!

Thanks and duh I should have checked the console output. Yeah this is spewing warnings. Whelp. Time to get to work.

Well I got the display issue fixed. And I added a screensaver shutoff.

But it's not recording right (I get these 9900 byte files which I'm going to guess are just headers or something), and it still crashes on attempting to stream, and I have no idea why.

So I go to build Qt 4 in case that's the problem, but it errors out, and tells me my OS version is not supported... blah.

it's not qt 4.

did you get all of the image formats changed so they match? there is probably a set for streaming and a set for recording. is ffmpeg printing anything to the console in qt creator? i will definitely have a look myself but i can't promise when it will be exactly.

HELLO!

Console's not erroring now. I'll check again on the image formats.

OK, I gut sucked into looking before I work this morning Smiley

Maybe I'm confused, but in Lossless_Recorder::write_video_frame, the first thing it does is *convert* the frame to the format it wants. So I'm at a loss as to why the original captured format should matter for recording.

RTMP_Broadcaster seeems to dot he same in its write_video_frame. In fact it's the exact same code:

Code:

    QImage input_frame = video_frames.takeFirst();
    input_frame = input_frame.convertToFormat(QImage::Format_RGB888);

Well I guess if the conversion's failing... I can check that next.

try using something other than rgb888.

i think yua may have been immune to this because i already switched it over to the 32-bit format.

HELLO!

Dinked around with that. But then ID ecided to enable some qDebugs. I have A CLUE.

Code:

...
record_frames(); audio_data.size() 0 video_frames.size() 477
record_frames(); audio_data.size() 0 video_frames.size() 478
record_frames(); audio_data.size() 0 video_frames.size() 479
record_frames(); audio_data.size() 0 video_frames.size() 480
record_frames(); audio_data.size() 0 video_frames.size() 481
record_frames(); audio_data.size() 0 video_frames.size() 481

Hmm. Well now that explains a lot. If it's never getting any audio to the recorder then it's not going to record anything.

I'm still working on it. Just thought I'd give an update. Smiley
