Software :: Mencoder Not Using Correct Audio Stream

Jul 28, 2009

I whipped up a script to convert VOBs to AVIs for storage on ym NFS backend. I'm using mencoder on CentOS5 to do the conversion.For 9 out of 10 videos, this works great. There is the occasional 1 that will not have the correct audio stream however. I've tried -alang, -slang, aid, etc. to no avail. Here is my script (also in case anyone else finds it useful), but can anyone offer any suggestions on how to get the correct audio in my avi? When I open the vob in mplayer, I get English. When I run it through mencoder, I get Spanish.

Ubuntu :: Streaming Audio - Capture Outgoing Audio On Windows Computer - Stream It Across Wifi To Netbook

Sep 20, 2010

I am fed up of listening to my (Windows XP) gaming computer through headphones so I want to get it hooked to the stereo.

Rather than use a heck of a lot of wire, I can sit my Ubuntu 9.10 netbook on top of the stereo and stream the audio across WiFi.

So, ideally what I am after is something to capture the outgoing audio on the Windows computer, stream it across the wifi to the Ubuntu netbook and finally play it through the speakers.

Fedora :: Mencoder - FPS And Audio Sync

Nov 22, 2009

I have found that if I change the FPS of a video, the audio is out of sync.

Is there a way in mencoder to have it correct this, and maintain the correct sync?

I don't think it is just a matter of audio/video delay. I have tried many times to correct this via that method, and it doesn't come close. Although, if I encode the video to another format, but with the original fps, the audio is sync'd.

Ubuntu Multimedia :: Transcoding Audio With Mencoder?

Mar 7, 2010

I'm trying to convert a video in .ogm format to .avi format so I can stream it to my PS3 via uShare. I'm using Mencoder and the following command to do it (to transcode the audio from vorbis to mp3 and the video from mpeg4 to xvid):

Code: mencoder input.ogm -oac mp3lame -ovc xvid -xvidencopts pass=1 -o output.avi.The only problem is, the video contains 2 audio streams - one Japanese and one English. Needless to say, I need the English one. The above command only seems to transcode the Japanese audio though!Here's what ffmpeg has to say about the input file:

Code:
Input #0, ogg, from 'input.ogm':
Duration: 00:24:16.12, start: 0.000000, bitrate: 1280 kb/s[code]...

what I can do to specify the correct audio stream to encode? Also, how can I keep the bitrate the same as the output.avi seems to default to 96kbps?I'm not sure which audio stream is which but a little trial and error will sort that out in no time.

Software :: Mencoder - How To Keep Audio Bitrate Settings At 192 Kbps

Nov 25, 2010

Mencoder settings... I'm doing a simple transcoding of an avi file from FFmpeg MPEG4 codec to XVID MPEG-4 codec. The problem is that the audio bitrate is changing from 192 kbps to 32 kbps. The audio codec for both files is mp3 (MPEG-1 layer 3). (I'm transcoding the FFmpeg MPEG4 encoded avi because my blu-ray player doesn't see, let alone play it. Any XVID MPEG-4 encoded avi files the blu-ray player sees and plays fine). I ran mencoder trying the four settings below but the audio bitrate still comes out at 32 kbps:

Code:
mencoder camping_en.avi -ovc xvid -oac mp3lame -xvidencopts bitrate=192 -o camping_us.avi
mencoder camping_en.avi -ovc xvid -oac mp3lame -xvidencopts bitrate=687 -o camping_us.avi
mencoder camping_en.avi -ovc xvid -oac mp3lame -xvidencopts bitrate=9146 -o camping_us.avi
mencoder camping_en.avi -ovc xvid -oac mp3lame -xvidencopts bitrate=192000 -o camping_us.avi

How to keep the bitrate at 192 kbps?

Software :: Mencoder Ignores Audio Bitrate Parameter

Dec 26, 2009

When I convert files with mencoder I get the output with incorrect audio bitrate. Seems that mencoder ignores the bitrate I pass to it. Here's my script:

Code:
#!/bin/bash
vbitrate=800
abitrate=128
#mkdir $2/../$2_rip
unlink frameno.avi 2> /dev/null
mencoder $1 -ovc frameno -oac mp3lame -lameopts abr:br=$abitrate -o frameno.avi
mencoder $1 -oac copy -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=$vbitrate:v4mv:mbd=2:trell:cmp=10:subcmp=3:vpass=1 -ffourcc DX50 -o /dev/null
mencoder $1 -oac copy -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=$vbitrate:v4mv:mbd=2:trell:cmp=10:subcmp=3:vpass=2 -ffourcc DX50 -o $2
unlink frameno.avi 2> /dev/null
unlink divx2pass.log 2> /dev/null

Result file should have 128kbps audio bitrate, but here are the results:
Input file:
02_seminar.avi, 42Mb
video: 432x320 00:05:10 25fps DivX5 1Mbps
audio: 48KHz 00:05:10 Stereo 138Kbps mp3

Output file:
02.avi, 34Mb
video: 432x320 00:05:10 25fps FMP4 802Kbps
audio: 48KHz 00:05:10 Stereo 138Kbps mp3

Why audio bitrate remains unchanged?

Ubuntu Multimedia :: Create Video From JPEGs - Use Mencoder To Add The Audio?

Jan 18, 2010

My 1st and only grandson turned 1 year old and we have taken about 1 million pics of him. I wanted to make a video from pictures taken in the past year. The first one is an ultra sound picture. The last one was taken this last Saturday. I have 153 12 MPixel pictures in a folder. They are named C001.jpg - C153.jpg (I can rename them if needed).

I had noticed mencoder or ffmpeg can create movies from jpegs. But, I didn't think about the frames per second. Would I need to make like 20 copies of each picture and then make it like 10 FPS? or something like that? Optimally, I would like to have a video where each picture lasts for 8-10 seconds or so and I would be able to add a song as audio. (I think I know how to use mencoder to add the audio).

Software :: How To Stream All Audio Through VLC?

Feb 7, 2011

We have remote offices and we'd like all announcements in one office to stream to the other offices, to play on the speakers connected to VLC machines there. We can stream audio with VLC when working with a file, but how would we stream all audio produced by a single machine?

Ideally this would stream anything coming in from AUX/Line-In jack, as well as any other sound that the computer would make. I'd prefer to use cvlc (CLI version) rather than the GUI VLC, but whatever I can get would be good.We can run either Debian 5.0.x Lenny with 0.8.6.h-4+lenny2, or Debian 6.0.x Squeeze with 1.1.3-1squeeze2

OpenSUSE :: Capture Audio Stream In VLC

This plays fine in VLC, and there's a "Record" button there but I'm never prompted to save the recording anywhere. I wandered through preferences but didn't see any default capture directory fields.Where/how do I capture the stream for playback later? The docs that I've stumbled across so far are pretty outdated (but I'm still googling).

Debian Multimedia :: Need To Adjust Fps In Audio Stream?

Oct 17, 2015

im creatind dvd's from others hd movies and ive seen theres an option to adjust framerate in audio, but ive never using that and i dont see the difference, when i play the video i see audio is syncronized with the video.for example, for a movie with 23,97 fps i converted to PAL (25fps) and i dont do anything to the audio, and it plays sicnronized then ¿Its neccesary to sync audio, and how its done with ffmpeg?

i do somethin like this: ffmpeg -i source.mkv -target pal-dvd -acodec copy mydvd.mpg (is audio fps syncronized because of the target?)if i dont use target, should is use sb like this?.: ffmpeg - i source.mkv -r 25 -vcodec mpeg2video -acodec ac3 -r 25 output.mpg

Ubuntu Multimedia :: Stream Audio From One Machine To The Other

Sep 16, 2010

I have two networked Ubuntu 10.40 machines and I am trying to stream audio from one machine to the other. I find on the surface everything works - I simply installed padevchooser and set the pulseaudio sink to the other machine. Now here comes the problem - whenever I do anything else involving network activity the sound crackles and hangs and it becomes hopeless. I've seen people elsewhere online complaining about crackling in relation to CPU usage but I can't find anyone talking about network usage.

In particular I often work on my office computers over VNC. I try to fire up VNC and it starts to load the remote desktop and the sound completely fails. I assume this is some kind of latency issue? Another good example is trying to watch a video on ..... - the sound plays at first but then as the video is being downloading in the background the stream starts to mess up. Listening to an mp3 in totem with no other network activity works fine.

Networking :: Possible To Stream All Audio From One Computer Over Network?

Jan 12, 2010

I have a MacMini connected to the big-screen tv on one side of my living room. I have my gaming computer on the other side of my living room. I often use VNC to control the Mac, so I don't have to get up to change which iTunes playlist I'm listening to, or play a movie, or whatever.I would like to be able to do something similar with the audio.Here's my problem. Sometimes it's really hard to get the volume just right when I'm at the far end of the room. If I increase the volume to a level where I can hear everything, it sometimes annoys the neighbours.

So, is there a way I can stream all the audio from the MacMini so I can listen to it using a Linux laptop at the far end of the living room without annoying the neighbours?Because I want to set this up for watching movies, it needs to be fast enough to stay in sync with the picture.(It might just be easier to run some speaker wire across the room, but I like to try to do things the hard way first. Heh heh heh...)

Slackware :: KDE4 Can Only Play One Audio Stream

Apr 2, 2010

Every KDE4 application seems to take over the sound card. If I'm playing a song in Amarok and launch Dragon Player, the song stops. If I'm playing a song in an xterm using "mplayer -ao alsa" and then launch Dragon Player, the song stops. Most annoying of all, if I'm playing music in _anything_ and then a notification sounds in Kopete, the music stops.However, if I launch two xterms and play two different MP3s by running "mplayer -ao alsa" in each one, both songs play. So software mixing is working with my sound card.

This made me wonder if KDE is outputting music through OSS instead of ALSA. Well, KDE's audio backend is set to xine, and xine is outputting through ALSA. Under System Settings->Multimedia->Audio Ouput, the only devices I see.

Debian Multimedia :: VLC Stream Capture Audio Out Of Sync

Oct 20, 2015

So I got myself a USB capture card (EasyCap) to use for capturing gaming, digitizing my kids' old VHS movies, etc. It works fine, I've been using VLC to view and record stuff from it, but I've noticed one issue. When recording streams via VLC, even with no other programs running to give VLC as much CPU time as it wants, the audio slowly falls out of sync. I've tried the MP4 (H264/MP3) container and the OGG (Vorbis/Theora) container.

Early on you can't hardly tell, but the further into a movie you get the more out of sync the audio gets, so that by the end of the movie the audio is a good 1-2 seconds off. It's not a set amount either so I can't just split the audio to a separate file then shift it one direction or the other to make up for the difference, because like I said, the offset starts out at nothing and gets progressively larger as the movie goes on. When I select "display locally", the video/audio that is displayed stays in sync, only the video/audio that gets committed to the output file falls out of sync, and it doesn't matter if I play the file with Totem or VLC.

General :: Windows - Use A Computers (would Be) Audio Output As A Stream?

Feb 28, 2010

I have two machines on a local area network (xp box and xubuntu box) and I want audio from both machines to be played from the same set of speakers. The problem is, the xubuntu machine doesn't have any sound output. There is no onboard sound card and all expansion slots are pci-x, so short of buying a pci-x sound card my only option for playing sound is to route audio through LAN to my xp computer.

I already have a program that will let me play music on one computer from another's speakers, but I am trying to set up a stream so that games and internet sound can be heard. Is it possible for me to do this?

Ubuntu Multimedia :: Asx Audio Live Stream Not Playing?

Apr 2, 2010

my problem is regarding .asx live streams. Up till 2-3 weeks ago I was able to listen to [URL] perfectly well with Totem under Ubuntu 9.10.

Since then whenever I want to start the stream, Totem darkens and nothing happens. I've tried Mplayer and VLC as well but neither of them work (but that's not news because they didn't work when Totem did either).

I had a look at the recent package updates in Synaptic to see if any audio-related ones had been changed and I have downgraded libaudiofile0 (to version 0.2.6-7ubuntu2) and gstreamer0.10-plugins-bad (to version 0.10.14-4ubuntu1). The problem still remained, so I updated them again.

The radio chanel works perfectly under Windows, and other .asx streams (for example [URL]) are working fine with Totem in Ubuntu.

Ubuntu Multimedia :: Can't Stream Audio After Upgrade To Natty

Jun 13, 2011

I have been using the streaming audio feature in Firefox for years, and have upgraded Ubuntu with each new release. I've never had a problem with streaming from my favorite radio stations until I upgraded to Natty. If I know the IP and use Audacious or another client, I can still stream through them-- but not from my browser any more. Flash-based content works OK too.I have upgraded two computers from 10.10 to Natty (desktop and laptop) and it has happened with both. the desktop is the 64-bit system (AMD), and the laptop runs the 32-bit OS (Intel). We have two other computers still running 10.10, and they're both still OK. I have uninstalled and reinstalled the xine plugin (which seems to do most of the streaming), VLC, and a couple of others. No luck. I don't think I see any gaps between the codecs installed for the 10.10 computers and the ones running Natty.I tried Chrome -- same result.

Red Hat / Fedora :: Audio Stuttering In Flash Video Stream

Feb 17, 2011

i've been experiencing an issue with audio playback for certain flash videos that stream from the web. most play smoothly, like the videos at videos. others have this strange background noise that is only present when there is audio (usually on news websites that host their own videos). when there is sound, there is a strange stuttering noise that disappears during the silent pauses.

here's a perfect example:
epidemic of tsa criminality: more agents caught stealing cash from luggage, another arrested for assault. the videos video at the top plays just fine. if you scroll down and watch the other video in the small box, you'll hear the stuttering. i have fedora 14 kde, adobe flash player 64 bit preview release 3 and rpm fusion codecs installed. the problem is also present in fedora 14 with gnome, same setup. the problematic videos play without the stuttering in ubuntu.
