  1. GeForce GTX 1080 vs NVIDIA GRID M40

    I have 8GB GTX1080, and memory do not worry me that much. Most likely I run out of other resources before GPU memory. I have different problems re-encoding 1080p HD streams to 720p streams. Random artifacts appear in the screen, when source is upscaled SD. I know, this sounds weird, but if stream is native FullHD (news from studio or whatever), then everything works fine for hours, but as soon some old upscaled SD show or film will start, then moving parts get blurry sometimes, although stream parameters do not change. Not often, but after every few minutes. BTW: What version of ffmpeg do you use? I have tried 3.3.6, 3.4.1, and latest from git and 3.3.6 is with less problems in my opinion.
  2. GeForce GTX 1080 vs NVIDIA GRID M40

    okay, that's weird. Usually different version libs can not be mixed, but if you say, that this combination works, then I maybe will try sometime ... Right now I have working patched set of 384.81 and not sure if it is worth to upgrade to newer nvidia drivers. Is it?
  3. GeForce GTX 1080 vs NVIDIA GRID M40

    yes, I did that more than once, but as far I know, patched libnvidia-encode.so.1 must be for the same version like rest of the driver. I mean, patched libnvidia-library for 384.81 (like you provided) can not be used with driver 390.12. Or am I wrong? I was asking, from where you get patched library's for every new nvidia driver?

    where is that right place?
  5. AvProxy

    that's the problem. Word is full of big expensive projects (starting from Wowza for example), but we need a simple, small, scalable and reliable utility for live http/multicast in and HLS out. If somebody has found such thing, let me know ....
  6. AvProxy

    I will keep eye on your work, and who knows, maybe I am even willing to pay for AvProxy, when it does everything I have dreamed of. :)

    If you not willing to share sources, then full static builds is you only option I think. And if you make static build, then including with all libs. needed for running it. well, that it is not "production ready" yet. Started from that library mess. I do understand, that you intend to keep it simple as possible. But if somebody want to use it in a IPTV environment, then some features is needed, started from PID filtering and so on. Even automatic filtering what drops all unknown or nonstandard streams for HLS, would do. You may say that use ffmpeg or astra then. I do use ffmpeg, but it is not very suitable for 24/7/365 live streams and quits on first few errors and often do not run more than a week without restart, etc. Astra is very good, but I do not like licensing terms of it - pay forever without receiving almost anything, and I prefer not to build my systems on software, what I can not run without constantly asking permission from somebody (license.cesbo.com).

    same result [root@tv29 bin]# LD_LIBRARY_PATH=./ ./AvProxy2-x64 Segmentation fault Another weird thing is, that Apple devices do not play those streams. Both iPad and iPhone with iOS 10.0.2. Just black screen and nothing. If I do make slices from same live source with ffmpeg (no transcoding) and serve them with nginx, then everything works. I think that is another side-effect from that "unknown data" or EPG stream. ffmpeg will automatically discard those. I am searching replacement for my ffmpeg+nginx HLS setup, and AvProxy seems like a perfect candidate, but it is too "beta" for now.
  9. AvProxy

    I am not sure, how to exactly use LD_PRELOAD on this case, but [root@tv29 bin]# LD_PRELOAD=./libc.so.6 ./AvProxy2-x64 Segmentation fault and this is not a good solutions anyway. There is not much point to include only some libs but all the needed ones.
  10. AvProxy

    thank you. tested it and found out, that indeed, c++ libs is half of the problem. On Centos 6 is still ./AvProxy2-x64: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by ./AvProxy2-x64) ./AvProxy2-x64: /lib64/libc.so.6: version `GLIBC_2.15' not found (required by ./AvProxy2-x64) and that audio glitch I pointed out, is still present. In theory that may be somehow related to my test setup (DELL PE1955 blade and Centos7) and if I wanted to rule this out with one of working servers with Centos6.x, then that libc problem surfaced again. EDIT: tested again with VLC and there is no glitches. Ignore that for now, I will dig a little deeper and try to figure out, what MAG250 do not like there ....
  11. AvProxy

    did send you a PM with live stream URL's. I discovered another glitch. When stream like this has gone through AvProxy, then every time when GET of the next *.ts occurs, after second or so, audio will be muted or stuck for a few milliseconds. Tested with VLC and MAG250. Dont know, is this related to the same problem.
  12. AvProxy

    thanks, please consider static binary option as well ...
  13. AvProxy

    There is no actual errors. None of the other software (astra, VLC, ffmpeg) don't say anything bad about it. If I manually remove this "Stream #0:6: Unknown: none ([5][0][0][0] / 0x0005)" stream with ffmpeg or astra before AvProxy, then errors disappear. I do not have access to the AvProxy source, and do not know what actually causes these lines, but I presume, that it expect a certain type of streams, but receives something weird, like EPG ot teletext, what is too short or start with wrong byte or it simply can't split from right place. If these errors do not hurt and mean anything, then they must be suppressed. about common index.m3u8 ... well, most of us most likely do not want to advertise every possible channel we have ... nginx as a proxy/cache or layer7 filters will help, but anyway ... much easier would be possibility to disable global playlist or make it optional in config.
  14. AvProxy

    neat piece of software indeed, but static binary is absolutely necessary. I did stuck several times to wrong libs, before installed that idiotic Centos7 and got it working. And errors need fixing. I did configure about 40 channels, and it spits out hundreds of such lines per second. Audio and video is fine, but it is hard to simple ignore them. ffprobe shows "Stream #0:6: Unknown: none ([5][0][0][0] / 0x0005)" and I think this is EPG or something which causes these errors. edit: and one question. Is there way to disable index.m3u8 ?
  15. DVB-C input needed

    What is most reliable DVB-C input for computer today? I have whole box of different DVB adapters (USB and PCI-e) but every one of them stop working after some time and few that works, don't have DVB-C.
