similar to: ffmpeg2theora 0.25 : This doesn't look like a Speex file

When I converted two files with ffmpeg2theora their duration changed shorter - they seem to play back with accelerated speed. When I play one of them with VLC, the video stops at 99 seconds but audio continues until 170 seconds. The other file is 120 seconds long but it is played back in 80 seconds. Here is ffmpeg2theora output: $ ffmpeg2theora --optimize --inputfps 25 -F 25 2002-05-23\ Juho\

https://gist.github.com/oneman/5394332 This is a little hack for sending -live encoded- WebM streams to Icecast from STDIN.

Hey all, I've setup a simple page that just displays a live webcam stream of me at work, and it supposedly falls back onto Cortado if your browser doesn't support the <video> tag. The URL is here: http://media.basilgohar.com/stream/ There's been a lot of talk about live streaming and low bitrate streams. Here is my command line (I've posted this before): time ffmpeg -f

Hello, (This is yet another newbie question.) My goal is to record Video and Audio, from a webcam and microphone, and record them in ogg format. (Using Theora and Vorbis.) I'm aware that I can use video4linux or video4linux2 to get the video. And use various API's for audio. And can use APIs like GStreamer to do the encoding, etc. But, if possible, I like something a little more

David, Does this work with already-existing WebM files, as in, does it parse them to only output at the appropriate rate? Or, is this meant only for realtime sources that are already appropriately rate-limited by their nature?

Has anyone noticed this? I have a video made with Final Cut Pro, which I convert to .mov via Compressor. This .mov file plays back fine in Quicktime. But when I then use ffmpeg2theora to convert to ogv, the video seems to play back too fast compared to the audio (I'm using VLC 1.0.2, the latest I believe, to play back the ogv file, and I also have an app that uses the recently

Hey Theorans, Yesterday and today I decided to try out broadcasting a video stream using Theora from my computer's built-in webcam. I was pleasantly surprised to find that, while maintaining a rate of less than 150kbps, the stream was of quite a suitable quality sending 640x480 video at 15 frames per second. For now, this is video only, by the way, I did not include any audio in the stream

Hi everyone! I'm trying to get clarification about v4l/v4l2 support in Wine. As there is no definite answer anywhere in web. I'm using Logitech webcam which is fully supported by v4l2. However, when I'm trying to use it with simple cam capture program in wine, I can see only that device is there, but I can't do anything else with it. I also did a little digging and so have found

Greetings.! In rapid action frames, I see lots of small rectangles which many together render a choppy sense of motion. I've attached screenshots in attempts to convey what I mean: http://24.16.26.121/screenshots/images/1253914810.jpg http://24.16.26.121/screenshots/images/1253914788.jpg I understand the lack of h/w acceleration and such, but I feel this can go away. If I am at all

I wish to transcode an AVI from 29fps to 15fps theora. I have tried many combinations. The nearest I have so far is to: 1) ffmpeg -i input.avi -f avi -vcodec rawvideo -acodec pcm_s16le -r 15 -ar 22050 -ac 1 intermediate.avi then 2) ./ffmpeg2theora-0.15.linux.bin -f avi -c1 -H 22050 -o out.ogg intermediate.avi This gives me an output I want, however, the intermediate uncompressed stage
