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.
Streaming / Transcoding failed: It seems your FFMPEG (libavcodec) installation lacks the following encoder: MPEG AAC Audio. 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. 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 have some videos in an mkv container that are 1920 pixels wide, but less than 1080 pixels high. This causes problems when playing the videos on a PS3 (after converting to an AVCHD system), because the PS3 won't centre the video, leaving a very large black bar at the bottom but none at the top. Is there a way to use mencoder or ffmpeg to losslessly add padding to the top and bottom to make the video 1920x1080?
It returns an error dealing just with the h264 codec saying that I need to use a vpre parameter? I can't find any documentation on using the vpre parameter.
i try to split mpeg file using ffmpeg. The splitting itself works OK, but the quality is lower. What should I do in order to keep the same video quality?
I like to install kazam a screencaster, so added the ppa. But during installation I get following dependency issue
[code]...
Obviously I like to ask the repo from where I can get those, but before that ; why debian missing those in its repo ( I am using testing ) and how ubuntu manage those to include in their repo ? May be a topic for debian decision maker, though interested to know.
Recently I tried to convert a .flv file to an mpeg file using ffmpeg. Although I changed directory to the directory in which the.flv file resided FFMPEG said the file did not exist. However when I gave the "ls" command the file was present. Where is my mistake?
last time i used debian it was missing some commands that were necessary for the stuff i was trying to install on itdebian has no software repositories (not as extensive as ubuntu but i guess thats why its so user friendly) and finding depencancies that are up to date is really hard seeing as though that the ubuntu site says is out of dateone of the commands that i really wished was on there was the MAKE commands like make make installnd i guess there are other make commands but is there an easy way (i am more than willing to try it the hard way if i have to)
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 regret to see the lack of facility for Guided install into the 'largest unpartitioned space on the drive'. I cannot find it either in the Desktop CD, or the Alternate CD. It seemed to disappear in Ubuntu 10.04 Desktop CD but did stay in the Alternate CD. But in 10.10 it seems to have gone completely.I found it a really *very* useful facility for myself, and also when helping others - when all I had to say to them was - 'delete the existing partition/s, do nothing more expect then, install using the facility 'Install into the largest unpartitioned space on the drive'.
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: Code: Select allIn file included from /home/sehny/Dokumenty/opencv-3.0.0-beta/modules/videoio/src/cap_ffmpeg_impl.hpp:65:0, from /home/sehny/Dokumenty/opencv-3.0.0-beta/modules/videoio/src/cap_ffmpeg.cpp:45: /home/sehny/Dokumenty/opencv-3.0.0-beta/modules/videoio/src/ffmpeg_codecs.hpp:98:7: error: ‘CODEC_ID_H264’ was not declared in this scope { CODEC_ID_H264, MKTAG('H', '2', '6', '4') },
I'm running the alsa upgrade script and I have ffmpeg installed so it finds the /usr/local/lib/libavcodec.a first when I want it to use the /usr/lib/libavcodec.so instead because otherwise make errors occur.
Can I point it to use the PATH to /usr/lib/libavcodec.a or should I just uninstall ffmpeg temporarily.
After updating Squeeze (i386) on my Via C7 laptop with the Via Openchrome video driver vlc video ouput shows only alternating white/green grainy vertical bars. I tried changing the video output driver to x11 and sdl without success. I'll be trying to find a fix and if successful I'll post back. For the rest of you just beware of the latest upgrades. More information - My AMD/ATI desktop also running Squeeze (amd64) updated fine. It has the onboard ATI 2400 video driver.
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:
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?
Have a pureftp server on OpenSuse 11.2 (x86-64 bit), KDE 4.3.5, dual core AMD. It responds to ftp clients on another machine (openSuse 11.1) within the same subnet (192.168....) and delivers lists of directories, changes directories, etc. The clients (gftp, jftp, filezilla, dolphin--tried them all) are unable to upload to the server (after a successful log-in on the server as a user, not root) with an error message that seems to indicate an inability to open the file on the client machine. Also logged in as user on the client machine. From FileZilla:
Command:STOR FCtinyLogo2.jpg Response:553-Can't open that file: Permission denied Response:553 Rename/move failure: No such file or directory
What am I missing in permissions? The directory where the JPG is located belongs to the user who is signed in, its in his home directory. The users on the two machines are not the same.
I was thinking to do my music producing completely on linux and found a plethora of good tools for it. The thing is I have two monitors and instead of launching manually every little app each time I feel creative, I want to make a script that launches all my favorite apps.
So long I have written this little bash script:
Code:
#!/bin/bash #Start my audio programs for music production (qjackctl --start)& (hydrogen --nosplash)& sleep 1 ardour2
So what it does is that it starts the jack server, then hydrogen and lastly ardour2. The thing is that I want hydrogen to start in the second monitor but don't know how. I have devilspie but I didn't have any luck on finding some command to choose display. I am aware of the --display flag that some programs have like firefox but hydrogen doesn't have it. Btw I use a different X server on each screen. is there a universal way to launch ANY kind of program on a specific display?
I have a working build of crosstool - it was built for gcc 3.4.3 using glibc 2.3.5 going from 32-bit x86 linux to 64-bit alpha linux. As far as I can tell -- it compiles correctly (output of alpha emulation matches expected) but it has a major flaw. When I use the cross compiler and attempt to add detailed debug information, it compiles, but does not have the debug information. For example, when I execute:
/home/leporter/crosstool/gcc-3.4.3-glibc-2.3.5/alpha-unknown-linux-gnu/bin/alpha-unknown-linux-gnu-objdump: hello: no recognized debugging information
Frustratingly - if I use my x86 gcc version 3.4.6 to do the compilation (same arguments, just using the x86 compiler, not the cross compiler) - it correctly embeds the debug information.
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?
after that if i call ffmpeg I will obtain this error ffmpeg: error while loading shared libraries: libavdevice.so.52: cannot open shared object file: No such file or directory
Ksysguard has always before shown a process table on one tab and the system load charts on a second tab. Loading Ksysguard produces an error message: "The file /home/*/.kde4/share/apps/ksysguard/Processtable.sgrd does not contain valid XML." That file contains nothing, as it's size in Dolphin is 0. Have updated KDE in Yast; removed Ksysguard 4 (which installed ver. 3) then re-installed ver 4. Still lack the process table.
This is OpenSuse 11.4 on a Toshiba A665 laptop. In other respects the system works perfectly, well almost. I'm examining a large number of files recovered by scalpel from a disk image created by ddrescue. This problem appeared while working through the nnnnnnnn.doc files. Most of them open in LibreOffice, but some produce an error message ("Not a Word 95 document"), open as slides (which is OK), or seem to freeze LO (with a CPU core at 100% in ksysguard). Lacking the process table, I'm having trouble killing the LO process (ps doesn't deliver the process number as expected; still studying it).
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
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 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

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.
