Debian Multimedia :: How Does Iceweasel Play HTML5 Videos By Default
Nov 5, 2015
I noticed that Firefox won't play HTML5 videos, or better said, the sites always return a Flash video instead the HTML5 version. So either I install Flash or I can't play videos.
However, with Iceweasel I don't have this problem. The sites always load with a HTML5 video instead of the Flash version. So no need to install Flash.
I checked plugins, extensions and even the user-agent string to see if there is some indication Iceweasel is using and Firefox don't, but I don't see anything special, so... how is it possible that using Iceweasel the sites load HTML5 video, but using Firefox the sites tend to use Flash?
I know that in Debian there is no need of installing Firefox, but right now I'm trying other distros and that's where I noticed about this problem. Then switched to my Debian installation and installed Firefox, and checked the same happens in Debian. Just for the record, in Windows it doesn't need Flash either.
I am using chrome Version 50.0.2661.75 (64-bit) running on Debian (Gnome).
I am having the following problem, since yesterday every time I want to play a video (for ex [URL]watch?v=UF8uR6Z6KLc) The music, logo in the video and functions work but the video doesn't play. I reinstalled Chrome, clean all the data, disable all the plugins, I tried as incognito and several other options and it doesn't work, before yesterday it was working (yesterday I updated all Debians packages).
What I mean by black screen is that whenever I view a video or if there is video content anywhere on the page, my whole monitor goes black for around 3 seconds then plays the video content.
I am running debian linux wheezy, and recently, all of a sudden, all videos in my iceweasel browser have been refusing to play videos of any kind at full volume. I am, however, able to download the video and play it at full volume on vlc player or sytem video player.Why iceweasel is acting this way?
I decided to switch from chrome back to iceweasel as my default browser. However, when I try to do that (as I used to) via Details -> Default Applications -> Web, iceweasel is not listed as choice.I tried to do it then from the shell with
I recently did a fresh Debian Squeeze install.The problem I have is that I cannot play any video. I tried opening mpg, flv and mov files with totem and vlc and they crash instantly.I think I have installed the packages (codecs, players, etc) required for playing videos.
I am using pepperflash and the youtube HTML5 player on Debian Sid, on an amd64 machine. I am having a problem where the video will just black out every so often, like every minute or two, the audio still works and I need to either go forward or backward in the video to get the image back. I have noticed it on youtube videos which I suppose uses the HTML5 player not pepperflash.
YouTube now automatically serves html5 content if it detects you are using firefox version 40 or above. Unfortunately as a result, all youtube videos are now served to me at 360p resolution, and there is no way to change that on the youtube web page.
Before upgrading firefox, I could watch hd videos using flash. The ability to switch to html5 was also available on [URL] .... But with the later version of firefox, the option to switch back to using flash is no longer there on that page.
When I could view both flash and html5 videos (with the older firefox), I found that html5 played back very poorly. flash, despite being a known resource hog, actually played back better (with no h/w acceleration of flash in linux, I resigned myself to expect to use faster PCs to run flash hd at full screen). Which is a great pity, as we all know flash is disappearing, but it appears I now have an even bigger issue with html5. Where's the hd video?
So how can I get a better html5 experience? My machine is an i3 with GTS250 nVidia running Stretch.
The problem of only getting 360p resolution is probably a bug in firefox. Once I can get hd, I am then uncertain if firefox could handle it.
The advice of setting 'media.mediasource.enabled' in about:config to true to get higher resolutions did not work for me.
When I do that, the [URL] .... says I have:
HTMLVideoElement, WebM VP8 and Media source Extensions support, and H.264, MSE & H.264 and MSE & WebM VP9 unsupported.
I have hardware acceleration enabled in firefox, and have the OpenH264 Video Codec (Cisco) plugin installed.
Some more info here: [URL] ....
I could switch back to using flash by using a user-agent switcher to fool youtube I have an older firefox, but that is a poor solution.
I can't play any of my avi, mp4 or even ogv files.I get audio but no video.This sort of points to a missing codec, but when I go into YaST I already appear to have the necessary ones (doesn't openSuse come with most out of the box anyway?).The file I am currently most interested in is (I believe) an Xvid.I already had libxvid4 but added xvidcore when it didn't work but this didn't help.I have packman in the repos (does it come by default in 11.3?)I installed vlc-qt to see if I could play it with VLC instead of Kaffeine but that didn't help either.
I cannot get AVI videos to play with the Totem movie player that comes bundled with Ubuntu 8.04 on the Dell Mini 9. I keep getting: "Could not determine type of stream." Randomly, one or two of the dozen or so videos on my SD card will work, but most will not. This is very frustrating because all the videos I download are always in AVI format.
I tried used the synaptic package manager find an alternative player and tried MPlayer, but that didn't do anything. I'd just get a blank screen on everything. Using the tutorial in this forum, I got GNOME Mplayer, which also didn't work, but even a video that worked with Totem would only play audio with GNOME Mplayer.
I looked in the repository for video codec updates but didn't see any. What do I do? Is there like a Winamp for Linux? This is a total bummer. I just want to play AVI files that are so commonly used for video.
I have used ubuntu for a long time but always using either a live CD or my Flash stick.
On past Thursday i decided to install ubuntu on my laptop and i did it . It is light and healthy (ha ha). Any way, I would like to play AVI, MKV, RMVB, and MP4 videos but i couldn't. I tried a lot of debian packages and drives (i.e. files with .deb extension) but no result except installing RealPlay that i am using it to play mp3 files only.
can you give me some packages to play those files. (I can't connect my laptop to Internet for the time being). In addition, I have Huawei E1750 USB Modem but the system does not recogize it. Is there any way to play those videos and surf the net using the modem in UBUNTU 10.04 LTS.
I install OpenSuse 11.2 +Non oss addon but I can't play anything such MP3s or videos and I can't config Pulse Audio to setup 5.1 channel on creative audigy value. what can I do?
Im trying to play some videos with vlc but they are too choppy, I guess my comp is too slow. They are something like 1700x1000 h.264. What can I re-encode these too to maintain good quality but increase playback speed? If possible, an ffmpeg command to do this would be awesome.
i have ubuntu 10.10 kernel 2.6.35-25-generic installed , 2GB ram, intel 41g express chipset. Machine is double boot - Ubuntu and Windows 7
Today I installed ATI hd 5450, everything works fine on Windows, but I have trouble with playing videos on Ubuntu. I logged in Ubuntu and there was this bold black line in the bottom of the screen (about 1/4 of the screen in total), I reboot and it was there again, so I installed and activated ATI driver System=>administration=>additional drivers Installed ATI Catalyst driver Reboot and that line was gone, but after a while I noticed that VLC and Movie Player won't play videos, I tried formats like avi, mkv, mp4. There is a sound but no picture. I can play ..... and other videos in browser (Firefox, Chrome). I tried installing a few other video players but it didn't help. I was able to play videos with integrated video card.
After updating the repositories, a long update took place... and after completed, my sound card was disabled. I had to reboot the system to have it working again, yet... mp3, mp4, avi files cannot be reproduced at all.
I just want to get rid of Win 7... and I find OpenSuse very stable, solid and friendly. I just installed version 11.2 in this old Toshiba Satellite, as a pilot installation prior the final one in a desktop PC.
I have got a new computer today, It's got most new parts in it but I installed all diffrent types of flashplayers, SMF players all that and I still can't play flash or watch videos.
Last few years (as long as I use linux) I tried several ubuntu/debian installations, on 6-7 different computers (desktops/laptops)What a notice in common on all these installations is that flash videos and games run REALLY bad.Is this a common problem for all debian based distros or I am doing something wrong? I din't give much attention in past (even if tried some repeating flashplayer installations) but last month I'm building a flash arcade site and this flash player problem become a real pain.
Installed Ubuntu 10.04 recently. Been exploring it now.
My PC config: Intel Core 2 Duo E7400 @ 2.8 GHz, Motherboard: Intel DG31 PR No graphics card.
Display on Ubuntu is not great as compared to Windows 7. Are there any device drivers available for Ubuntu?? Or any other tweak to improve the display?
Also the video playback isn't that great. Videos get stuck once in a while and I also cannot play .MKV videos.
I recently ran into a problem though. using mav. meerkat I have figured out how to rip dvds using acid rip, medibuntu and some ..... tutorials. Then I tried to put them on my ipod using gtkpod. when this did not work I did some research and realized the video files needed to be converted. At first I tried avidemux, it seemed to work but when i put them on my ipod (video white 80 gb) I tried to play them and the screen just went black and several seconds later was sent back to the menu. Then I tried winnff, but there was no ipod preset only a rockbox ipod preset which I tried with the same result. I then tried openshot using these parameters -ipod libx264 libfaac 1.25 Mbit/s -> 1.5 Mbit/s 128 kbit/sto160 kbit/s Quarter Square NTSC 320x24029.97HzAVCHDQuicktime 7Still same result. I have gotten purchased mp4 videos to work using gtkpod, so I am assuming it is a conversion problem. Also the converted mp4 I made using openshot plays fine on banshee player
Has anyone seen a problem in which all videos play only in black and white? It matters not which player I use VLC, Mplayer, Banshee. I am a new user using 11.04
when i try to play a flash video the visual works but not the audio and totem tells me i need the suitable codec which it says is gstreamer-bad and when i attempt to install it, it says that it conflicts with gstreamer-really-bad but if i remove gstreamer-really-bad and install gstreamer-bad totem gives me an internal data stream error instead and even visual won't work. so i ran totem--debug and this is the terminal output with gstreamer-bad when trying to play flash video.
I was having problems with pulseaudio, which I eventually cleared up. Now sound works on everything except flash videos and games. I have tried to reinstall adobe-flashplugin in synaptic, but I get this:
E: adobe-flashplugin: subprocess installed pre-removal script returned error exit status 2
When I try to remove Adobe Flash Plugin 10 in Ubuntu Software Center, I get this:
I have been away from Linux in general and Ubuntu since 2006, but now wish to make Linux, and probably the Ubuntu distribution, my main operating system, especially for the Internet. I have been using Open Office since version 1.0, so no training or migration is necessary there. However, I have one challenge with my Ubuntu 9.1 ... movies which play under Windows will not play in Ubuntu. Under Windows Firefox needs Adobe Flash Player 10 to play these videos ... is there some open source software that will give Ubuntu Firefox the same capability?
