If I understood what you meant, from Google translator, you're saying that: "TV stream is at most 20 frame per second." Right? Yet, you didn't provide any information about what you're trying to watch, nor if libVLC is using vdpau or not. The stream frame rate comes from a few factors: 1) the amount of frames per second at the recorded video; 2) the amount of time required to decode a video stream; 3) the amount of time required to display a single frame. If the video is recorded with a low fps (1), there's nothing we can do: as far as I know, libVLC doesn't try to generate inter-frames to convert a low-fps video into a pseudo-higher-fps video. Both (2) and (3) are directly related to the size of the video. I mean: a 4K resolution video takes a lot more time to be decoded/displayed than HD. Also, both depends on having a CPU (or GPU) good enough to allow watching videos with high fps. If your CPU/GPU aren't good enough, the only solution is to upgrade your hardware. If they are, that's something that you could fix, likely by installing some packages that will allow libVLC do to hardware decoding. What kind of video are you trying to watch? What's their resolution? Are you using hardware acceleration for video codec decoding?

Created attachment 109322 [details] attachment-30802-0.html My GPU is nVIDIA GTX1070 Where do I find the logs or how do I retrieve those in Kaffeine that started with --debug to provide them to you? I have been working with UBUNTU 17.10 and have no idea about Linux. In reality, I can not speak English. I write all the texts in German and translate them with the Google translator. I then copy these into my emails. ________________________________ Von: Mauro Carvalho Chehab <bugzilla_noreply@kde.org> Gesendet: Montag, 11.

(In reply to nolli111 from comment #5) > My GPU is nVIDIA GTX1070 Ok. You should then be sure that libVLC will use GPU for video codec. This link could be helpful: https://wiki.videolan.org/VLC_GPU_Decoding/ You'll likely need to install some Ubuntu packages (if you didn't yet), in order for video accel to happen, using vdpau. You'll need to install them with something like: $ sudo apt install mesa-vdpau-drivers vdpau-driver-all VLC version 2.2 and upper should use it automatically. Ubuntu 17.10 comes with vlc 3.0-git. So, it should automatically detect it. Eventually, you might need to install the nvidia proprietary driver. personally, I don't like it. I stopped using it (and nvidia boards) years ago, because it used to be painful to make it work right. So, if I were you, I would try to make it work with the opensource nouveau driver first. > > Where do I find the logs or how do I retrieve those in Kaffeine that started > with --debug to provide them to you?

This bug can be a duplicated bug: https://bugs.kde.org/show_bug.cgi?id=389783 As reported there, with some channels, enabling interlacing is too CPU intensitive. Please try disabling interlace. On -git version, this is now disabled by default.
