I have Fedora 25 mate-desktop and ATI/AMD driver on my laptop. And external monitor 1920x1080 27. On my external monitor bad pixel resolution.
How fix it?

Several questions regarding hardware acceleration with ffmpeg (which I think is NOT same question as this one):
How can I tell if my version of ffmpeg support hardware acceleration or not, and what are the acceleration features it support?
From the output of an transcoding process, can I tell if ffmpeg is using hardware acceleration or not?
I am using ffmpeg to pull H265 video from camera, and convert it to H264 HLS chunks. The problem now is the transcoding process is too CPU intensive. I hope to use hardware acceleration. Due to the application, I cannot use expensive GPUs such as NVidia cuda platform. If using only Intel HD graphics comes with CPU, can I significantly lower CPU usage when transcoding H265 => H264? What is the estimated performance gain in %?
Thanks.
If your CPU support for example Intel Quick Sync than you can significantly reduce the CPU load using hardware acceleration (in my test case below it was from 90% using libx264 to 20% using h264_qsv). And after enabling the hardware accelerated decoding it reduced the CPU load from 20% to 4%. So in summary from 90% to 4%. But the load depends also on other things like bitrate, resolution and CPU/hardware.
Encoding
First of all you need to know, what encoders have been enabled in your FFmpeg version. To check this you can simply execute
ffmpeg -codecs
In this this you should find your target codec (h264):
[...]
DEV.LS h264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 (decoders: h264 h264_qsv h264_cuvid ) (encoders: libx264 libx264rgb h264_amf h264_mf h264_nvenc h264_qsv )
[...]
Take your attention on the "encoders". Some are software-, some are hardware-encoders. This list is dependent to your OS and the enabled encoders during FFmpeg compilation. To get a short description of each encoder you can execute:
ffmpeg -encoders
[...]
V....D libx264 libx264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 (codec h264)
V....D libx264rgb libx264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 RGB (codec h264)
V....D h264_amf AMD AMF H.264 Encoder (codec h264)
V....D h264_mf H264 via MediaFoundation (codec h264)
V....D h264_nvenc NVIDIA NVENC H.264 encoder (codec h264)
V..... h264_qsv H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 (Intel Quick Sync Video acceleration) (codec h264)
[...]
Note: not all encoders might actually work. E.g. if you have no NVIDIA graphics card the h264_nvenc will not work.
Here on my Windows machine I will choose the "h264_qsv" (Intel Quick Sync Video acceleration) encoder. On macOS you want to use "h264_videotoolbox":
ffmpeg -i mysource -c:v h264_qsv -c:a copy output.mp4
Pay attention on the output quality: libx264 might have a better quality by default than a hardware accelerated encoder. So make sure that you finetune the encoding using e.g. a defined bitrate (-b:v 6M for 6MBit).
This encodes the input using the h264 encoder of Intel Quick Sync (because of the -c:v option). Please find more details on
https://trac.ffmpeg.org/wiki/HWAccelIntro
Decoding
Using the option "-hwaccel auto" before the inputs (-i) tries to use hardware accelerated decoding as well:
ffmpeg -hwaccel auto -i mysource .....
If a hardware decoder is available it is automatically used. If not then FFmpeg falls back to the software decoder. Check the console output to see what happens:
[hevc # 00000176c91d0fc0] Using auto hwaccel type dxva2 with new default device.
when embedding a bigger video in firefox i got audio bugs. It crackles like an old movie.
No problems in Chrome.
The video was converted with VLC to MP4/MOV with H-264 video and MPEG audio codecs.
Because of its a very high quality video, the file size and Bitrates are very high. Is it possible, that firefox has a problem with that?
I know, usually you should never offering a video with that size on a web template, but its local hosted for an kiosk-mode project.

We are using FFMPEG to convert iPhone video to MP4. This requires an AAC decoder which is not included in any binary distributions of FFMPEG (due to licensing issues). The solution is to download the FFMPEG source and compile it yourself. I've done this, apparently incorrectly, as I cannot decode the audio stream. I am getting this error:

I suspect that I failed to compile and include the correct codec library when I built FFMPEG. The problem is I don't know which library I should have built/included. I haven't found anything that says to decode QDMC audio in FFMPEG you need the XXXXX library.
Here's the complete list of decoders that my build supports:

Any idea what I did wrong when building FFMPEG?
Here's a link to the video file that caused the problem: step-2.mov
FFmpeg version 3.3 and above
QDMC is supported by both AudioToolbox (Apple OSes only) and FFmpeg's native QDMC decoder.
To use FFmpeg's native QDMC decoder, use decoder strings qdmc (or qdm2 for version 2) (e.g., -c:a qdmc).
To use the AudioToolbox QDMC decoder, use decoder strings qdmc_at (or qdm2_at for version 2) (e.g., -c:a qdmc_at).
Go give Mulvya a +1 for pointing out the new QDMC decoder that Paul B Mahol added to FFmpeg.
FFmpeg version 3.2.x and below
FFmpeg supports decoding QDMC, but only through the third party framework named AudioToolbox. AudioToolbox is created by Apple and is only available on Apple operating systems (iOS, macOS, and tvOS).
This means that you can't decode QDMC using FFmpeg, since you're using CentOS.
A native QDMC decoder was added to FFmpeg on 7th Jan 2017. With that, you should be able to decode on any platform.
I have two physical displays. Currently xmonad thinks they are separated by some physical distance so when I move my cursor from one display to the next, the mouse disappears off the edge of one display and I have to keep moving the mouse some distance before it appears on the next display.
Another sign that they're misconfigured is when the screensaver shows an animation across both screens, there's a huge section from the middle that's missing (not that I actually care what the screensaver looks like)
In gnome, there's the display settings panel where you can drag one display's position relative to the other to match your physical reality (like if one monitor is slightly higher than the other)
What is the equivalent in xmonad?
If it helps, here is the output of xrandr

Thanks in advance for any help!
In your previous question, Eric recommended to use arandr (a graphical frontend for xrandr) which lets you position the screens easily - i guess this can be done using xrandr as well, but here the GUI simplifies your life.
Again, this question is independent of xmonad. Since you were unsure which window manager you are using (in your previous question) i think you need to understand: xmonad is a window manager, as opposed to a desktop environment like KDE or Gnome. Using a window manager you'll have to rely on tools provided by GNU/Linux to do certain things, where a desktop environment often provides such tools, e.g. Screensaver, Screen locking, status bars and so on.
I have noticed that EnumDisplayDevices and EnumDisplayMonitors report different information on which monitor is attached to which port.
For example, i have 4 monitors attached to my graphics card. 3 of them are 1920x1080 and one of them is 1280x768.
The information i get from EnumDisplayMonitors is:
1920 1080 \\.\DISPLAY1
1920 1080 \\.\DISPLAY2
1920 1080 \\.\DISPLAY3
1280 768 \\.\DISPLAY4
and the one from EnumDisplayDevices is:
1280 768 \\.\DISPLAY1
1920 1080 \\.\DISPLAY2
1920 1080 \\.\DISPLAY3
1920 1080 \\.\DISPLAY4
Also i noticed that the order in EnumDisplayDevices is sometimes shuffled, so it could also be:
1280 768 \\.\DISPLAY1
1920 1080 \\.\DISPLAY4
1920 1080 \\.\DISPLAY2
1920 1080 \\.\DISPLAY3
Anyways, which one is the correct one?
I am looking for this because i want to read the EDID data from the correct monitor.
