I am looking for a video player which can allow me to step forward and backward frame by frame by using keyboard shortcut. I have video with 24fps. Presently i am using mpv. I am trying the following shortcuts: . Step forward. Pressing once will pause, every consecutive press will play one frame and then go into pause mode again. , Step backward. Pressing once will pause, every consecutive press will play one frame in reverse and then go into pause mode again. Step Forward works smoothly but stepping backward works very slaggy. I also tried https://github.com/mpv-player/mpv/issues/4019#issuecomment-330727387 > Djvview has the option of caching decoded frames in memory, is this > possible with mpv? Maybe with a user specifiable RAM cache, like > djvview? I use mpv for previewing renders and so on, the ability to > smoothly play backwards would be really useful. > > http://djv.sourceforge.net/ djv_view caches few seconds doest not cache the entire. Is there any video player where i can smoothly play around with frames

After dist-upgrade'ing my distribution (Devuan Daedalus to Excalibur), and trying to run celluloid, I get the error:

(io.github.celluloid_player.Celluloid:16054): GLib-GIO-ERROR **: 
17:33:53.331: Settings schema 'io.github.celluloid-player.Celluloid' does not contain
a key named 'menubar-accel-enable'

How can I fix, or ignore, this problem? The celluloid version is 0.25. **edit:** Currently seeing this with 0.26 .

I want to be able to just insert a DVD movie and be sure I'll have full access to all its features. - Can this be done without VLC in Linux? **VLC** is maybe the best video player out-there and as far as I can tell the best DVD player for Linux, but it may happen that it fails from time to time (I sometimes lose video, audio, or synchronization between those) - so that it may be useful to know if there is a way to have full access to all features of a DVD movie with a different application. Example (tested in Manjaro and Mint KDE): - once the DVD disk inside the computer drive, VLC can show the menu like so: and each menu entry may lead to other sub-menu entries: This example is in **VLC**. Can other player do as well as this? Or better: I remember that in Windows I used players that at any moment during playback were able to show the first level of the menus by selecting a specific option. I cannot seem to find that in VLC neither - clicking the 'DVD Menus' added to the interface, it will just restart from the beginning. What happens when trying the same DVD with a different player? Well, **many video players don't even have an "Open DVD" option**. **SMPlayer** has that option, shows the first level of the menus but does nothing then (it seems to see the menus just as a video stream or something). **Gnome MPlayer** also has it, but cannot find the dvd as it looks for it by default in /dev/dvd and it doesn't have a way to change that. When starting the DVD in this player anyway, it treats menus as video stream. Even without an "Open DVD" option I was able to test with other players. Many do not see the menus as such but play them as a video stream, and so the menus are not usable. (I tested **mpv, Gnome MPV, bomi, Gnome MPlayer, Baka Mplayer, KPlayer, KMPlayer, Dragon Player**) **Totem** player was able to display the first level of menus just like VLC but clicking any of them was just starting the first entry.

I am running AlmaLinux 9 and have a problem playing back audio using 'aplay'. I have a service running as root, and when it tries to play the audio file I get error: aplay: main:831: audio open error: Host is down If I login as root and play the file it works fine. What's the difference and how do I fix this?

In Windows you can simply right-click a media file and edit its metadata - no additional software needed. Why is this ability absent in Linux? Is there some inherent technical limitation in Linux that prevents this?

I generally use VLC and that works fine most of the time but at a recommendation to check out mpv and mpv-based players, I have been trying to see if SMPlayer would also work for my needs. However, I am having problems with getting it to detect external subtitle files located in a subfolder, e.g. $ cd some-show-s01/ $ tree . ├── Some.Show.S01E01.mp4 ├── Some.Show.S01E02.mp4 ├── Some.Show.S01E03.mp4 └── Subs ├── Some.Show.S01E01.English-1.srt ├── Some.Show.S01E01.English-2.srt ├── Some.Show.S01E02.English-1.srt ├── Some.Show.S01E02.English-2.srt ├── Some.Show.S01E03.English-1.srt └── Some.Show.S01E03.English-2.srt I've also tried it with just a single sub per episode, whose name matches the video file exactly (e.g. ./Subs/Some.Show.S01E01.srt) as well as both variations under a sub-folder named 'Subtitles' instead of 'Subs'. VLC picks up external subs for all four of these scenarios automatically. Is there any way to get SMPlayer to do the same? If not, are there any other Linux video players besides VLC that support this layout? I'm on a mix of Fedora 35 / 36 (desktop + laptop) and comfortable compiling from source if necessary (altho converting dependent package names from other distros is sometimes challenging). I am using SMPlayer v22.7.0 (rev 10091). # dnf list installed smplayer mpv Installed Packages mpv.x86_64 0.34.1-2.fc35 @rpmfusion-free-updates smplayer.x86_64 22.7.0-1.fc35 @rpmfusion-free-updates edit: I am able to play the video in mpv itself and have subs load using: $ cd some-show-s01/ $ mpv --sub-file-paths='Subs' --sub-auto='all' ./Some.Show.S01E02.mp4 However, changing SMPlayer settings, per [this discussion](http://old-forum.smplayer.info/viewtopic.php?f=2&t=8743) , under Preferences->Advanced->MPlayer/mpv Options to add --sub-file-paths='Subs' --sub-auto='all' to the options field and hit Apply, I got the following error message: > /usr/bin/mplayer -noquiet -slave -identify -nofs -sub-fuzziness 1 -nodr -double -nomouseinput -input nodefault-bindings:conf=/dev/null -nokeepaspect -wid 92274705 -monitorpixelaspect 1 -osdlevel 0 -subfont-osd-scale 3 -progbar-align 80 -ass -embeddedfonts -ass-line-spacing 0 -ass-font-scale 1 -noflip-hebrew -ass-styles /home/myuser/.config/smplayer/styles.ass -subcp ISO-8859-1 -alang japanese,jap,jp,english,eng,en -slang english,eng,en -subpos 100 -volume 100 -ss 27 -vf-add screenshot=/home/myuser/Pictures/smplayer_screenshots/shot -noslices -af-add scaletempo -softvol -softvol-max 200 --sub-file-paths='Subs' --sub-auto='all' /home/myuser/Videos/podcasts/some-show-s01/Some.Show.S01E02.mp4 > > > Unknown option on the command line: --sub-file-paths='Subs' > > Error parsing option on the command line: --sub-file-paths='Subs' > > MPlayer 1.5-11 (C) 2000-2022 MPlayer Team > > ID_EXIT=NONE edit: Solved. My issue was two-fold: first, I needed to add some parameters to tell the underlying video player that SMPlayer uses to load subtitle files from a folder. second, I had specified parameters for mpv but my SMPlayer had defaulted to MPlayer so I had to change which video player it was calling. Alternately, I could have looked into what parameters would be required to do the same thing in MPlayer (didn't do this so can't confirm if that's possible).

KDE has a feature called "media controls", with which I can control media from the lock screen. I would like to add this feature to a music software I'm working on. I tried to find the necessary API (or a hint to it) in VLC (a software that implements this feature) and the web, but on both I didn't find anything.

When I start a VLC instance, I can control it with media keys (Fn, BT headphones, etc.). But if I then start a second VLC instance simultaneously, I cannot control that one with media keys. That's probably intended, it would usually be pretty annoying if both reacted. But if I then close the first VLC instance, nothing reacts to media keys. And sometimes I simply want to decide that from now on, media keys should control a different program. PulseAudio has so crazy many features, surely I can somehow switch my media keys over to another program or instance, right? How do I do this? (Having a command line method for scripting would be nice as well.) Setup info, in case it's relevant: Manjaro 21.1.2 KDE 5.22.5 PulseAudio 15.0 VLC has some buttons bound, but most are set via KDE's system settings or just left default. Both have the exact same issue.

smplayer has an option that allows deleting the currently playing video. This worked well in windows 7, and even in debian 9 till about an year back. It brings up a confirmation dialog box, and if I click 'yes' it deletes the file and starts playing the next file in the playlist. I tried it recently (now debian 10 buster, both kde & gnome. Both mplayer and mpv engine.) and it does not delete the file (When I click 'Delete File from Disk', nothing happens. Closing the app, also does not delete the file.). Tried files placed on both 'home' (ext4) and ntfs, same result. Could you tell me why/how it can be solved? If you have smplayer installed, could you please test it? To get the delete button onto the toolbar (its not available by right clicking on the video, even last year when it was working well it was like that), you will need to: Right click on the toolbar. Select "Edit Main Toolbar". Then find and select 'Delete File from Disk' from the 'Available Actions'. Now it will appear on the toolbar and can be used when a video is playing. ------------------ Another test: I opened smplayer from the terminal, then opened a file using Ctrl+F and then tried to delete the file, hoping so get some error messages, but there was nothing! >u@p:~$ smplayer > >QObject::connect: No such signal MyApplication::commitDataRequest(QSessionManager) > >This is SMPlayer v. 17.11.2 (revision 8807) running on Linux > >u@p:~$

Is there a video player for Linux that shows the milliseconds of time elapsed? There's an [extension for VLC](http://addons.videolan.org/content/show.php?content=149618&forumpage=2&PHPSESSID=fee4d78b932f9cb53441a6ddba589908) , but according to comments at the link it doesn't work with newer versions.

I want to convert text in file a.txt to sound & play it using APLAY. any suggestions please?

**EDIT: I removed and rewrote most of the post to make the question more direct and to make the post a lot shorter. You can of course view the edit history to get the previous version.** Using bspwm on Arch Linux. playerctl to control media, sxhkd to bind media keys to playerctl commands. I'm trying to find a way to get the latest active media player so when I use the media keys to play/pause a song/movie/.. , my pc automatically controls the latest active mediaplayer. For instance, when Spotify happens to be open in the background and I'm watching something on VLC, it knows to control VLC and not Spotify when I press media keys. Right now, if both are open, VLC always gets priority from playerctl. What I need is a way to ask dbus which mediaplayer is currently playing a song, so I can keep it in a file. --- EDIT: I found a way to ask each spotify and vlc using: qdbus org.mpris.MediaPlayer2.vlc /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.PlaybackStatus and qdbus org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.PlaybackStatus but I'd like to automatically ask **all** mediaplayers, not each one by name. I tried to do it with org.mpris.MediaPlayer2.* but that doesn't work. Any ideas?

I want to pause playback after headphones have been unplugged, then resume after they were plugged back in. My current solution uses ACPI to detect plug / unplug, as shown here . To play / pause the playback, I use xdotool key XF86AudioPlay. **This solution works fine in the basic case:** - music is playing, headphones are plugged in - headphones are unplugged **=>** music pauses - headphones are plugged back in **=>** music continues playing. However, I don't want to resume playback if it wasn't **active** when the headphones were unplugged. **Imagine this scenario:** - start up the PC with headphones in, - play music, - pause music, - unplug headphones, - plug headphones back in. The last point is where the problem lies – the playback would resume after the headphones are plugged back in, although it was not active at the time they were unplugged. Moreover, on my system, xdotool key XF86AudioPlay simply toggles the playback, whereas xdotool key XF86AudioPause does nothing. That makes things even worse: - start PC with headphones in, - play music, - pause music, - unplug headphones _(MUSIC STARTS PLAYING!)_. --- So what I need is to **detect play / pause / stop events** as well as plug / unplug events, to be able to correctly react in all possible scenarios. This state machine describes the desired operation: --- The one idea that came to my mind is to re-bind the keyboard shortcuts for play / pause / stop to add the state machine logic. This has the drawback that playback _always_ has to be controlled using these keyboard shortcuts, instead of eg. Rhythmbox buttons, which is somewhat impractical. Also, if I close Rhythmbox while playing, the state machine will stay in a playing state. Of course I could have a 'daemon' which will wait until Rhythmbox is closed, and then set the state to stopped. But what if it's not Rhythmbox that plays the music, what if it's for example VLC, etc.? This approach is ugly and unreliable, so I would like to avoid it. --- **My question:** How to detect when media playback was paused / resumed / stopped?

I run AIMP audio player with wine and can not use special multimedia keys like play/pause, next/prev. IS there any way to make them work with wine? For example: Fn+F9, Fn+f10, Fn+F8...

I'm using Cinnamon on Devuan ASCII (which is essentially Debian Stretch without systemd). I'm trying to change the default player for AVI files from Dragon player to Gnome-MPV. But - while this seems to be possible, after making the change the default player is _still_ Dragon - nothing has happened. I would try to debug this myself if I'd gotten any kind of an error message, but I don't even have that. What do I do?

I'm running a basic application on Orange-Pi DVK with Gstreamer-1.4.0. While running the application it throws this error: AL lib: (WW) alc_initconfig: Failed to initialize backend "pulse" AL lib: (EE) ALCplaybackAlsa_reset: snd_pcm_hw_params(self->pcmHandle, hp) failed: File descriptor in bad state While running on Ubuntu (running on VMware), it works well. Why is this not running properly on the Development kit (Orange-Pi) and how can I resolve this?

I'm using **RHEL 6** . I'm unable to play the video using **Movie Player**. It shows an error, Movie Player requires additional plugins to decode this file. The following plugins are required : MPEG-4-AAC decoder and H.264 decoder. But RHEL asking for a subscription. How to solve this problem or Suggest me any alternate softwares to install ?

Beside VLC, very few dvd players have [access to all DVD movie options, namely menus](https://unix.stackexchange.com/a/239771/32012) , and mpv is not one of them, but I use mpv to access external subtitles with DVDs and have started to appreciate very much this very simple and light and yet very capable player, so that I would like to provide an answer on **how mpv might be used as main DVD player** in spite of (or maybe because) its very minimal GUI.

I want to install XBMC – Kodi Media Center on linux and I used these commands to install it: sudo apt-get install software-properties-common sudo add-apt-repository ppa:team-xbmc/ppa sudo apt-get update sudo apt-get install kodi When I used the first command it shows me this: Reading package lists... Done Building dependency tree Reading state information... Done software-properties-common is already the newest version (0.96.20.2-1). software-properties-common set to manually installed. You might want to run 'apt --fix-broken install' to correct these. The following packages have unmet dependencies: google-chrome-stable : Depends: libappindicator1 but it is not installable E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution). So what can I do to solve this problem?
