I would like to know how to demux the audio from a flash video file (copied from /tmp while browsing a video site). I would prefer to avoid re encoding if possible.
View 5 RepliesIf I convert an audio file to a different format (such as mp3) using a pipe I lose the tags.
Code:
ffmpeg -i <filename> -f wav - | lame - output.mp3
If I knew the tags of the input file I could put them back using a program such as id3v2

I've used VLC for years, in both windows and linux. In windows streaming, you can select "NONE" for a Video Input, and just stream audio. This is not the case for Ubuntu's version.What can I do to stream just audio in VLC?

View 9 Replies View RelatedI 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.
I have an old computer that I have put Ubuntu on. I would like to connect it to my stereo and stream audio to it from my laptop, so that it plays through the stereo.
I'm hoping to find some software to put onto this old computer to make it work similarly to an airport express. Anyone know of any software like this?

I'd like to be able to play it in Rhythmbox. Is there a way to figure this out?
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.
I was wondering is somebody could look at this simple script that I am working on. I cannot get it to output to my home directory. I noticed the message "bad input or output format" in the VLC verbose terminal.

View 2 Replies View RelatedI 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.

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
I just had a quick question. I would like to burn a DVD to disc. The VOBs in the Video_TS folder have 3 Audio tracks: Stereo, Surround, Mono. By default it plays the Stereo track. Is there any way to change this? ffmpeg -i [insert_video_location] in the terminal gives me:
Code:
Stream #0.0[0x1e0]: Video: mpeg2video, yuv420p, 720x480 [PAR 32:27 DAR 16:9], 9800 kb/s, 29.97 tbr, 90k tbn, 59.94 tbc
Stream #0.1[0x80]: Audio: ac3, 48000 Hz, stereo, s16, 384 kb/s
Stream #0.2[0x81]: Audio: ac3, 48000 Hz, 5.1, s16, 448 kb/s
Stream #0.3[0x82]: Audio: ac3, 48000 Hz, mono, s16, 96 kb/s
Will 0x80 always be the default? Normally this wouldn't be a problem, but I'm going to be playing these discs on a DVD Player without a remote (can't help it), so I won't be able to switch the audio on the fly, and they have no menus. You put it in, and it goes straight to the movie.
How's the quality of the sound that gets to your loudspeakers? What components do you have - brand, specs, mode and distance of computer to amplifier?[URL].. Mid and bass sound good.

I am looking at ripping the audio from a very old episode of 'In Our Time'. The episode is so old that it predates the podcast (which of course, would solve all my problems). I would like to use something like icecream or VLC to rip the audio from the 'Listen Now' link on this page. Unfortunately I am having a hard time finding the actual URL. The player itself is a Flash widget, so it is something more complicated than looking for OGG, mp3 or RAM file extensions in the page source. If there are some nifty command flags I should add when invoking icecream on the command line, I am all ears.
View 2 Replies View RelatedI have an Asus EEPC that I use in my classroom whenever I want to show a movie. I normally keep all of my educational videos as ISOs, and then simply move one over to the netbook when needed. I normally use VLC for playback. With the latest upgrade, however, I'm having a few difficulties. No matter what DVD I choose to show with VLC, the audio stream will randomly drop every 10 minutes or so whenever I am using KDE as my desktop environment. In order to re-enable the audio stream, I have to either completely stop playback OR reconfigure the audio output in VLC.
(It does not matter if I change it right back to what it was, I will get audio for another 10 minutes or so). I've also noticed that if I pause playback, sometimes the audio will not re-enable when unpaused. Strangely, however, I do not have this behavior at all when I'm using Gnome as the desktop environment. I get seamless audiovisual playback and never have to fiddle with the audio. Is this a documented problem in Phonon somewhere? How I might better backtrace what's going on?
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.
I have two video files (Xvid) and would like to combine the video from one of these with the audio track of the other, in order to create a new video file.
This is somewhat complicated by the fact that I would like the resulting audio to be a mixture of the two original audio tracks, for instance, during some time segments, I would like to switch from one to the other, but the video should always be the same.
Another issue that complicates the things is that the two audio tracks have different bit rates, and when I briefly managed to merge the two, one of the audio tracks was playing much faster than the other. To clarify, the audio tracks should not overlap but just be played at the different time during the video playback.
I am trying to do this by using Audacity. The problem is that I am fairly new to Audacity and I have not been able to find any info in their user guides regarding this specific issue.
I have made numerous audio CD's with Brasero, but recently I had to make one and mid way through the burning process I am given this error: Could not decode stream. Or some variation like that. It ruins the cd and after I get the error I can not eject the disc.
View 1 Replies View RelatedI'm using it on a small IBM machine in my closed ( ) which is my multimedia center, file sharing, router, http server & others. To escape the cable paradox, lately I came up with an idea to stream music from my mobile phone (LG GD880) via bluetooth to my SUSE box (which has it's audio output linked to my HIFI Sound system). This means pairing the devices and of course set the SUSE box as reciever. I found how to accomplish this here and here .
The problem: While trying to complete the above tutorial(s), I found that in /etc/bluetooth there is no ' audio.conf ' file, only ' main.conf '. If I insert the option: Enable=Source in main.conf, it has no effect what so ever. This means that org.bluez.AudioSource will not show up in D-Feet, thus I cannot take the next steps. What can I do? Is there another way to accomplish the audio streaming?
I'm a new openSUSE 11.2 user and lately I've been getting repeated notifications from KDE saying that "the audio playback device HDA Intel(AD198x Analog) does not work" I get audio if I stream videos off the Internet but Amarok can't seem to play audio.
View 1 Replies View RelatedI 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.
It appears I thought I was taking photo's with my Nikon CoolpixS5 but they are saved as .mov files. When I watch file, I see the picture, and then it's over in a second. How can I extract the image from the .MOV file? If it's of any relevance I used digikam to recognise my camera.
View 9 Replies View RelatedFor about three months I've been going up and down the internet looking for a solution to this problem... Basically I take this distance learning course. Every lesson is sent to me via email in PDF format and it includes many audio examples which are embedded in the file. The problem is none of the Ubuntu readers seem to recognize it, and the Adobe reader says I need a plug-in which does not exist for my system. I quote: "We're sorry, but the third-party media player required to play the selected media file in your Adobe PDF document isn't available for your system". I've been taking this course for two years and I still have two more to go. I contacted the company that sells this course and they were as puzzled as I am... Is there a way to extract the audio from the PDF? Or alternatively open it with another application? I would hate to have to go back to windows for this one issue...
