Either recordmydesktop produces corrupted files or nothing (mencoder, ffmpeg, kdenlive, pitivi) can open it. (How come totem can?) I need to just stick some text and some sound on this clip but nothing works.

At least one output file must be specified Actually the video has embedded subtitles. I thing that is stream 0.2 in real media container. How can i pull that data out ?
I'd like to take audio track from a video clip in FLV container and save it to something playable by portable music players. Are there any easy to use tools for that? I know how to do that using console tools (mplayer+lame/oggenc), but I'd like to get something clickable, preferably for GNOME.
I have two seperated video clips, that captured same event from two cameras. i would like to create one clip, that will show one on the left side, the second on the right side, and play together.
I've created some time-lapse videos from photos, using this command: ffmpeg -i IMG_%03d.JPG -s 1440x1080 -sameq video.MP4
And it worked great. Now I want to join several of these time-lapse videos to make a single, longer video (all the input videos have the exactly same format). I already tried using: cat video1.MP4 video2.MP4 > stitch.MP4
but the output ends up being equal to video1.MP4, I don't want to transcode nor changing any parameter of the video, I just want a end-to-end stitching, as if those videos were on a playlist.
somebody gave me a dvd of my little music group, and i used a ubuntu application to edit out two clips (i think i used avidimux--it was about a year ago). it produced a clip in avi format, which is not accepted by anything. i'd like to upload it to my facebook or even videos, but need to convert it. i've tried about everything, but have had no success. i just downloaded winff and tried that. the conversion window produce a lot of information ending with "unknown encoder 'libx264'," whatever that means.
does anyone know how i would convert a clip from avi to mpeg4? it's driving me nuts.
I am rather a new user of ubuntu.. I tried playing songs and it played properly after it installed the necessary softwares.. But when I tried playing videos, the video clip opened and then closed again.
I've had this camcorder for a while, and my knowledge on them were little back years ago when we got it. Any ways the video is recorded on a tape that comes with it. If I had known then, I would have made sure it was recorded onto the SD card. Anyways there is this old video that I wanted to extract and I have Kino installed and have my camcorder connected to the computer with a firewire cable. Kino/Ubuntu does not seem to recognize an input. Though the camcorder does. Anyone know if there is something I'm supposed to do?
I'm trying to extract the audio from an mp4 video file and convert it to mp3 using ffmpeg. The problem is that the resulting audio file is only 3m2s long, whereas the video file is 8m15s long. Anyone know why the audio file is being truncated? Am I doing something wrong? Apart from being truncated the mp3 file plays perfectly. Here's what ffmpeg has to say about the video file:
I have some video clip and I want to add a title in its buttom center. For exemple, My clip is video.mp4 and I want to add the title "hello world".Does ffmpeg (or mencoder) enables me to do this?
I'm having trouble to find the right ffmpeg options to encode a video that can be read on a htc G1 cell phone. I have used several codecs and formats but none is working.
I have followed these instruction to install ffmpeg and x264 [URL]
Here is my ffmpeg config :

I'm trying to find out how to add watermark to a video using a ffmpeg via console, because I have to do it quick. There is tutorial on ..... (other forums use also this video tutorial) for this but there is a small problem - in ffmpeg 6.1 there is no more vhook subsystem which is used in tutorial...
Anybody had any success in getting ffmpeg to work as advertised with video capture from a webcam? I really want to convert the webcam output to VP8 or H264, but apparently ffmpeg can't even capture the webcam with a video4linux device.
But FFmpeg is not accurate and it started the video from a nearby point instead (from 00:24:46~). I tried to add 2 seconds to my starting point and it took another frame (not what I wanted).
I'm trying to encode a wmv file to flv with ffmpeg. The video codec is WMV3 and the audio codec is wmap (Windows Media Audio Professional). The command I use is:
As you can probably see the audio codec is not supported. Is there a way to encode WMV3+wmap with ffmpeg or any other tool in Linux? Windows Media Encoder in Windows is able to encode such files to a supported codec. For example: WMV3+WMA2/WMV2+WMA2, I could then encode it in Linux. I'm trying to find a way to directly encode WMV3+wmap in Linux.
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?
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
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.

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 spent about a half hour wrestling with different website tutorials about how to convert a file with ffmpeg and figuring out how to get all the video quality options right. Then I discovered you can just use the -sameq option and it figures it all out for you if you don't want to change the vid quality but just want it in another format. Thought I'd leave this on the site in case anyone else finds himself in the same boat.
I'm trying to write a bash script for gpodder to automatically convert video podcasts to play on my media player. I'm using ffmpeg for the conversions (compiled myself with all codecs enabled). I'd like to avoid resampling the video or audio whenever it's unnecessary but ffmpeg seems to want to resample my video even if I only give it audio parameters to change.For example I have a test video with the following parameters:
