Ubuntu Multimedia :: FFMPEG AAC Sound Misplaced
Mar 20, 2011
I am converting a lot of videos through FFMPEG using X264 and AAC as the codecs. Some videos have mono sound, some have 2 channels, and some have 5.1. I compiled FFMPEG from source so the codecs are installed correctly but I keep getting an error with 5.1 sound. After the conversion the video plays the sound that should come from the center speak through the right. I tried libfaac and the experimental aac codec inside FFMPEG and both give me the same error.

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

I am trying to record a video clip, using my webcam, but sound synchronisation is always poor. I have used Cheese, UCView and VLC. One possible cause is explained in the reply to this question, but I am not an expert. In desperation, I now want to try ffmpeg. The ffmpeg documentation gives the following example
Code:
ffmpeg -f oss -i /dev/dsp -f video4linux2 -i /dev/video0 /tmp/out.mpg
My system has no /dev/dsp, but does have /dev/snd with these files
Code:
$ ls /dev/snd

Code:
ffmpeg -f oss -i /dev/dsp -f video4linux2 -i /dev/video0 /tmp/out.mpg
I want to use alsa, not oss, but need to know the alsa input device name (/dev/dsp is created by loading the oss modules). By running alsamixer, I have nutted out that /dev/snd/controlC0 refers to the HDA Intel sound card, ~controlC1 is my USB webcam and ~controlC29 is the microphone built in to my notebook, but these are control devices, not inputs.
[Code]...
However, that does not explain which device is the mic built in to the laptop: by my calculation, it should be pcmC0D1c, but there is no such device. In /proc/asound/card0/pcm0c/ I have directories for sub0 and sub1, which I am guessing relate to the mic jack and inbuilt mic respectively. Do two physical mics share one logical device somehow? I am starting to really confuse myself, if you haven't guessed that already.
I think my question boils down to "How do I record a video clip on Fedora 14 using ffmpeg?", but I am specifically interested in knowing how to specify each of the alsa sound input devices for my system.

I recently reinstalled ubuntu (switched from x64 to x86) but kept the /home partition. Ever since, the notification bubble keeps showing misplaced as in the attached picture. I tried reinstalling the notify-osd package but to no avail. I looked around and found that you cannot customize anything about this bubble.
Ok, I don't want to customize it. I want to fix it. How can I do that please?
I'm using lucid with all my packages up-to-date

I FINALLY convinced my wife to try Ubuntu on her laptop. We selected Install 10.4 side-by-side with XP. The grub menu shows up, but Windows is not listed. She's happy with Ubuntu so far, but I'd like to know why I can't use XP anymore. btw, I actually made the mistake of using the import accounts option, which filled up the new partition and made Ubuntu unbootable. I deleted some things from the command prompt, and it's running fine now.HP Pavilion1.5 GHz512MB Ram

I've got a bunch of HD files in .mkv format that I want to convert to a format that the 360 will read (currently just trying .avi files) so I can stream the media to my xbox360. I'd rather avoid transcoding the entire file, so I tried unpacking the .mkv file into audio and video (and subtitle if necessary) and repacking said file into avi using ffmpeg. The repacking is where I am having the problem. Here's the commands I tried at first (it might look familiar):
Code:
mkvextract tracks file.mkv 1:temp_video.avi 2:temp_audio.ogg 3:temp_sub.srt
ffmpeg -i temp_video.avi -i temp_audio.ogg -vcodec copy file.avi
However, I keep getting this annoying error:
Code:
Error while opening codec for output stream #0.1 - maybe incorrect parameters such as bit_rate, rate, width or height Where stream #0.1 is the output audio stream to the .avi file. I think I have narrowed it down to the fact that the input streams are all 6 channel (5.1 surround sound) which mp2 doesn't support (the ffmpeg audio default) so I did this instead:
Code:
ffmpeg -i temp_video.avi -i temp_audio.ogg -vcodec copy -acodec libmp3lame file.avi
I'm still getting the same error, but when I use
Code:
ffmpeg -i temp_video.avi -i temp_audio.ogg -vcodec copy -acodec libmp3lame -ac 2 file.avi
to change the sound to stereo it works. Problem is I'd like to keep my media in surround sound. Any thoughts on how to get all 6 channels in the new mp3 file? I'm fairly certain that mp3s support 5.1. And after some messing around, I haven't found that my ffmpeg can transcode audio format from 5.1 back to 5.1. So since (I think) the 360 can play .ac3 files I decided to just copy both the video and audio file to the .avi file sans transcoding using
Code:
ffmpeg -i temp_video.avi -i temp_audio.ogg -vcodec copy -acodec copy file.avi
however now about halfway through, I run into this error:
Code:
NULL @ 0x22f3a00]error, non monotone timestamps 62562 >= 62562
av_interleaved_write_frame(): Error while opening file I can't seem to find any solution to this problem anywhere online, does anyone know how to get around this? I'd prefer to use ffmpeg for this if possible. (so I can write a script and just attack an entire directory at once) For what it's worth, I'm using the latest ffmpeg in the ubuntu (karmic) default repositories.

It seems more and more people are encoding with the MKV container on bit torrent these days, and a lot of the shows I'm watching are starting to release almost exclusively with .mkv formatted videos. This is not a problem if I want to watch the shows on my computer but I've become accustomed to watching them on my PlayStation3 using my thumb drive. It seems the offical documentation for the PS3 includes a list of supported codecs [URL], but when I use FFMPEG to convert with libxvid video and aac audio in the MP4 container my PS3 says the output video is not supported. I've also tried most combinations of libxvid, libx264, mpeg4 for -vcodec and aac, libmp3lame for -acodec in several different container formats but nothing seems to work. I have found one option that always works:
Code:
ffmpeg -i inputfile.mkv -sameq -ac 2 outputfile.mpeg
I don't like doing it this way, however, as the output file is twice the size and the audio quality is terrible. If I don't reduce the audio channels to only two using -ac 2 FFMPEG throws an error (apparently MKV audio supports 6 channels). And preserving the video quality in MPEG video using -sameq produces too a large file (and I prefer to keep my files as lossless as possible). Ideally I want to save the files on an external HD I have but if a single episode of a show is 1.5 GB it's not very pratical.
Anyway, the PS3 docs say it supports h264 and xvid with aac audio, but apparently I'm doing something wrong. Has anyone sucessfully used FFMPEG to convert an MKV to MP4 for use on a PS3?

I have a .mkv container with proper video (h264/~6000kbps) and audio (DTS/1500kbps). For some reason I want to have similar quality but with another video and audio codecs. For video it goes well and ffmpeg is very helpful here, no problems. Also, I want DTS to become AC3/320-448kbps/5-6 channels. Commands like this:
Quote:
ffmpeg -i in.dts/mkv -acodec ac3 -ac 5 -ab 448k out.ac3
gives me not proper reordered sound in channels, so I hear center on the right, music on the left, etc.
Is there a way to make that properly with ffmpeg?
Also, I have a question about multi core encoding cause I have a quad processor. Ffmpeg seems not using them in all the way, I get something like 25% of CPU usage while encoding. Command -threads, even using the h264, does not make any extra load of cpu.

I'm making little animated bits in GIMP with the gap package. I can only get GIMP to encode the files as .avi. Problem here is that when I try to use any converter, it compresses 80MB files down to 1MB-4MB files and, unsurprisingly, the video quality is terrible. WinFF and ffmpeg (via terminal) output at a drastically reduced size. Is there some way to keep the files big/big-ish? I don't want to lose any detail.

I've been recording one of my classes with my android phone, and the file it gives me is an .amr file. I'd like to convert that to .mp3, and I was hoping I could use ffmpeg to do it via the command line. Here's what I did, and the output that I got:

Right now, I need to use a dual-monitor setup. Be it for my casual desktop usage, or to my projects and programs presentations with a slideshow. The latter is critical and that's why I'm here.So, after some Intel Drivers update, some programs started to work nicely, faster and beautifully. But it corrupted my Dual-Monitor Setup. I don't know what to say, I'm totally desperate. I had to show one of my programs to my teacher using a projector, but with the dual monitor corruption, I called in sick today. I need to use the netbook screen to make changes on the program and the second monitor/projector to show the program working.
I'll show some pictures, but I'm without a camera right now, so I'll use one china-phone that's hanging around here to take a picture. Sorry for the quality. Both Monitors, you can see on the right of the bigger one the corruption I'm talking about.

I installed Audacity to convert an mp4 to an mp3. Now, I don't necessarily need Audacity to do this, but for the time being I'm more concerned with getting Audacity to work properly as opposed to getting an mp3 onto my iPod.
In Audacity, I went to Edit>Preferences>Libraries. For the MP3 Export Library, Audacity recognizes LAME, but under the FFmpeg Import/Export Library it says "FFmpeg library not found." I hit the Download button and read this page on how to install FFmpeg, noticing the warning about needing FFmpeg 0.5 or later on Linux.
I fired up Synaptic and searched for "ffmpeg," chose the vanilla version and installed it along with two dependencies which I don't exactly remember but I bet they were libavformat52 and libavdevice52.
Back in the Audacity Preferences window I chose the "Locate..." button to point to the newly installed libraries, but Audacity is not recognizing/installing them successfully. I've tried pointing to the following files:
/usr/lib/libavformat.so.52
/usr/lib/libavformat.so.52.36.0
/usr/lib/i686/cmov/libavformat.so.52
/usr/lib/i686/cmov/libavformat.so.52.36.0
/usr/share/lintian/overrides/libavformat52

Did I install the wrong version of FFmpeg or libavformat? Any pointers?

I have a file with about 6 .flv files and I wish to batch convert them to libmp3lame. I have tried making a #!bin/bash script with all the files in e.g.
Code:
ffmpeg -i filename.flv -sameq -acodec libmp3lame -f asf filename.mp3
I have inserted all the filenames individually into the script but when I ran it I got too many errors and i was wondering if someone knew a quicker way to do it e.g. a script that would batch convert all .flv files in that folder to .mp3 format.

1 o merge with ffmpeg
ffmpeg -i /home/pt/t/pa1.flv -i /home/pt/t/pa2.flv -vcodec copy -acodec copy /home/pt/t/dd.flv
the problem is: the merged file ( /home/pt/t/dd.flv ) just contain one file--the first one
/home/pt/t/pa1.flv,there is no the second file--/home/pt/t/pa2.flv in the /home/pt/t/dd.flv

I recently developed a taste for the Alac format and ffmpeg will oblige with this line of code
Code:
ffmpeg -i <input> -acodec alac <output>.m4a
and this worked beautifully one file at a time and
How does one do all the files in a given folder? Is there an asterisk one adds as in shntool.

I've seen posts with similar titles on these forums, but I know nothing about the plethora of codes out there and all those thread seem to be way over my head. I've installed ffmpeg (an unrestricted version) but I can't convert m4a audio files to mp3 audio files. I installed a package called 'libavcodec52' from synaptic because it came up in the search results for 'm4a' and its description said something about m4a and ffmpeg but still no luck..

When using libmp3lame with ffmpeg is there a way to use lame options?
Code:
ffmpeg -i foo -acodec libmp3lame foo.mp3
For example:- --vbr-new, --abr <bitrate>, -V (n) and -q <arg>
I think it is possible to pipe ffmpeg to lame then use the options.But is it possible to do it without a pipe.
Code:
ffmpeg -i foo -f wav - | lame --vbr-new -V 4 - foo.mp3

Following this tutorial: [URL] I got everything to work, but the running capture framerate is about half of that set (-r 30). I'm stuck on getting something like 14 fps, which is noticeably choppy. I have a relatively decent system (dual core intel), so I don't think I'm hitting the limitations of the machine (it's only using little over the single core during the process).
