Debian :: Run Ffmpeg As Background Job
Mar 26, 2016
I'm currently running ffmpeg from a windows machine and realized it's rather redundant as I could be running it from the Debian (headless server) machine instead. What I'm trying to achieve is to get ffmpeg running as a background job...
Effectively, as far as I've gathered, this should be enough:
Code: Select allffmpeg -re -hide_banner -i "LIVE_INPUT_1" -f "LIVE_OUTPUT_1" &
But it's not working - when I run the command from terminal to check it, it works fine... but when I try to run it as a background job it creates the job but no output is generated. According to posts around the web, other people have been successful at running background jobs like this for transcoding static files.Should it be done differently or is this an issue with ffmpeg itself?

Since ffmpeg 6 is out for some time, when will Ubuntu Lucid afford such a new ffmpeg package from its repository?

How do I convert an ovg to avi file?
Why was ffmpeg removed in Jessie?
I read through more of this thread than I wanted to. [URL] ....
Does libav provide command line utilities to do something like converting ovg to avi, or determining the length of an mp3 file? Why is there absolutely no explanation as to why libav was preferred over ffmeg?

As I understand (and remember) debian does not package x264 with its ffmpeg. [I say remember because I have a debian-multimedia line in my sources.list that I believe I added when I wanted a x264 enabled ffmpeg]
Is this status still the same? Do we still need to compile ffmpeg by hand if we want x264?

First when trying to play some video Totem (as was set as default application) asked about missing decoder then offered installing of gstreamer-version-xx, but it couldn't as described below. I removed Totem and installed MPlayer and Gnome-MPlayer interface and everything is perfect in regard of playing video files
Now I wanted to install other package and it again needs this gstreamer0.10-ffmpeg package:
Depends: gstreamer0.10-ffmpeg but it is not going to be installed

I am trying to stream from a webcam to mp4 file with avconv/ffmpeg with the GRBG pixel format. I can find a lot of ffmpeg commands and other stuff on google about a webcam stream to file with ffmpeg, but none of them use GRBG pixel format and are working for me ...
I have never tried something like this before
Output of v4l2-ctl --list-formats-ext:
Code: Select allioctl: VIDIOC_ENUM_FMT
    Index    : 0
    Type    : Video Capture
    Pixel Format: 'GRBG'
    Name    : GRBG
        Size: Discrete 162x120
        Size: Discrete 324x240
How to get this working?

I use ffmpeg to covert video files for the net.
Code: Select allffmpeg -i infile -vcodec libx264 -vpre ipod640 -b 250k -bt 50k -acodec libfaac -ab 56k -ac 2 -s res.mp4
which works good. I was wondering if I could use larger resolution presets, but
find /usr -iname '*.ffpreset' only gives
#/usr/share/ffmpeg/libvpx-360p.ffpreset
#/usr/share/ffmpeg/libvpx-1080p.ffpreset
#/usr/share/ffmpeg/libx264-ipod320.ffpreset
#/usr/share/ffmpeg/libvpx-1080p50_60.ffpreset
#/usr/share/ffmpeg/libx264-ipod640.ffpreset
#/usr/share/ffmpeg/libvpx-720p50_60.ffpreset
#/usr/share/ffmpeg/libvpx-720p.ffpreset
with only 2 presets for libx264.
I installed ffmpeg from deb-multimedia. Is there a package which provides further preset files? There should be e.g. hq, max etc..

I use Kino to transfer dv from my camera and also use it for video editing, but there are very few GUI options when it comes to transcoding the edited files into, say, h264. Kino is using ffmpeg, and I know there are a plethora of options. For instance, here is the output of the logfile from a file I made with h264 and the best quality available in Kino.#options: 768x576 fps=25/1 cabac=0 ref=1 deblock=0:0:0 analyse=0x1:0 me=dia subme=8 psy_rd=1.0:0.0 mixed_ref=0 me_range=4 chroma_me=0 trellis=0 8x8dct=0 cqm=0 deadzone=21,11 chroma_qp_offset=-2 threads=2 nr=0 decimate=1 mbaff=0 bframes=0 keyint=300 keyint_min=25 scenecut=0(pre) rc=abr bitrate=2048 ratetol=2.0 qcomp=0.50 qpmin=2 qpmax=31 qpstep=3 ip_ratio=1.25 aq=1:1.00Frankly, I am not that impressed with the result, and would like to use settings that give a better result, e.g. adjusting bitrate and more passes

I've been trying to compile OpenCV3 beta for Debian Jessie, but I can't figure out how to compile support for video I/O .Tutorials that can be found on-line usually use ffmpeg library, but as I found out Debian 8 replace this library with libav (?). Of course I found tutorials how to remove libav and install ffmpeg, but I would rather try to find some another way.
I use OpenCV3 beta from URL...
When I use this switch
Code: Select all-DWITH_FFMPEG=0 compilation succeed, but there is no support for video.
When I don't use that switch, then I get this error:

I am running a video script on my server and I am very new to running a dedicated server and commands. Most of our site was setup but other and someone has broke something and no one seems to know how to fix.
Here is the issue. We run a script that uses these requirements
[Mod edit]Adult content Link removed
requirements
Now our server guy ran a update inside webmin for debian and now our videos still convert but wont make thumbs. Here is what he did.
Now updating libsmbclient ..
Now the AVS script wont make thumbs and webmin still wants to do 3 more updates that get unmet dependencies errors. Here they are when we try to run another update.
Building complete list of updates ..
Now what we need to do is either undo the update he already did or maybe get the one its asking for now to work but not sure which one will fix our thumb generating problem? Here is the error in the log file of the AVS script.
Seems stream 0 codec frame rate differs from container frame rate:

I am running 64 Bit Debian, 6.0 install with VLC and libavcodec52, libavformat52, and libavdevice52 installed. I also installed recordmydesktop which creates an ogv file, and I would like to use VLC to convert the file to an MP4. Then I can add it to a project under Open Shot Video Editor.
I get the following errors when I try to convert the file: Streaming / Transcoding failed: It seems your FFMPEG (libavcodec) installation lacks the following encoder: H264 - MPEG-4 AVC (part 10). If you don't know how to fix this, ask for support from your distribution. This is not an error inside VLC media player.Do not contact the VideoLAN project about this issue.

This is not an error inside VLC media player. Do not contact the VideoLAN project about this issue. I've used Google to search for the error message, searched on the forum.videolan.org, and searched on this forum. So far, I've not found a lead to the solution. What am I overlooking/missing?

I'm wondering if anyone distributes mplayer, mencoder, and ffmpeg, up-to-date builds of each and their associated dependencies (x264, faac, xvid, etc).I had to compile all that stuff myself and fought with it, and finally got it working.
If no one distributes latest builds, then I was thinking of going further with what I've done to help others: virtualbox lenny and automated compiles of all packages and putting up the builds, with latest revisions of mplayer and ffmpeg from their source code repos. Using LD_LIBRARY_PATH to isolate the build so any modern linux can run the produced binaries, with only glibc as a dependency.

I received a few updates today, one of which is mplayer. Now mplayer is broken and from what I can gather it's because it's incompatible with the version of ffmpeg I have installed. But the real problem is that mplayer and ffmpeg were originally installed from the debian-multimedia repo but the update for mplayer is from the debian repo. I can't go back because this new mplayer is dependent on libdirectfb-1.2-9 whereas mplayer from debian-multimedia is dependent on libdirectfb-1,2-0.
In case you want the error from mplayer:
mplayer: relocation error: mplayer: symbol codec_wav_tags, version LIBAVFORMAT_52 not defined in file libavformat.so.52 with link time reference

I am running a dual-boot of LMDE and Debian Squeeze XFCE, and I actually have a Debian XFCE question. How can I tell what is running in the background. I have been tweaking my Debian install since I first installed it about 3 weeks ago, and I keep adding to the RAM usage. What is the best way to see what else is running out there and whether or not is it necessary?

I'd tried to run HDD bench mark at my Debian Stable called iozone3. It performed I/O actions which took too long. Ctrl+C to terminate process. Everything went as always. It just terminated. Upon completion of program I used laptop for some more time. During shutting down X-Desktop shut down normally. Terminal window was showing command line with lines <Stopping this and that daemon...> but instead of normal black colour background with white text it changed into red background with white text. What does it mean? Is it safe to restart laptop?

I've spent a good part of the day wrestling with replacing the grub background image. I did my homework and over the past few days read every thread and suggested link I could find on this forum. I had a clear idea of what needed to be done. Spacefun had quite a laugh at my expense! It was not fun at all. First, I put images in /usr/share/images/desktop-base and made changes in /etc/grub.d/05_debian_theme to point to the image I wanted to use. Yes, I updated grub but spacefun had some sort of deathgrip on the setting.
So I threw an image in /boot/grub. Well, Grub found that and spacefun was gone but there was no background image when it booted - only a black background! At this point, I just surrendered and replaced spacefun-grub.png with the image I wanted and it finally worked. There are links in /usr/share/images/desktop-base/ that point to /etc/alternatives/ which in turn point back to the original file in /usr/share/images/desktop-base/ which I think may be the root of the problem but I didn't just want to start deleting links willy-nilly. Does anyone think that might just set things straight? This whole process is several steps backwards in customizing ability from what it was with grub and GDM a few years ago. This is NOT progress!

I recently installed Debian 8 with the Xfce Desktop Environment. I don't like the background in the login screen and want to change it. After some Googling I discovered that the path to the background is stored in the file /etc/lightdm/lightdm-gtk-greeter.conf.
Unfortunately, whenever I change the background field I'm left with a black background during login. (Yes, I triple checked that I spelt the path correctly). Does the login background have to meet some criteria I don't know about, like being a certain resolution?
EDIT: Here's the content of /etc/lightdm/lightdm-gtk-greeter.conf:
Code: Select all#
# background = Background file to use, either an image path or a color (e.g. #772953)
# theme-name = GTK+ theme to use
# icon-theme-name = Icon theme to use
# font-name = Font to use
# xft-antialias = Whether to antialias Xft fonts (true or false)

I have a perl script which runs a mini webserver allowing me to do various things. I'd like to have this script run when the machine starts up, and constantly run in the background.How should I achieve this? I want the script to regardless of whether anyone is logged in or not, so I can't put it in any bash-related files.

After much searching and trying of more complicated methods for changing the GRUB-PC background image, i found method that seems to work. The simplest one! I installed grub2-splashimages, which created a new folder in /usr/share/images, called grub. From there it appears to be as simple as adding the image of your choice, then adding "GRUB_BACKGROUND=/usr/share/images/grub/your_image" to "/etc/default/grub" file, the running "update-grub", of course.
Only problem is it doesnt work for the image i really want. So my question: What qualities should an image have if it is to be successfully used as a GRUB-PC (GRUB 2?) background? I have read that you do not need to resize the image anymore, indeed i tried resizing it to match the size a default image form the "/usr/share/images/grub" folder , and saving it with the extension .tga in Gimp and it did not work. The image i want to use is quite large, it is also black and white/grey-scale and in the .png format.
