A client of mine needs to accept a bunch of different video files and convert them to FLV. My experience with FFMEG on a previous project has highlighted that there will be some troublesome files. Depending on the price my client will pay for a professional service. What are people using and how are you finding the service? Thanks. ...
I have converted any video format to 3gp file format using ffmpeg on one server. But on another server it not works.

I need to split an flv file into chunks of the known size on linux server. For example my original file is 9Mb and the chunk size is 4Mb. So I should get 3 parts - 4Mb, 4Mb and 1 Mb. Seems that FFmpeg can split only by time. Mencoder can start by time (-ss TIME) and finish by size ( -endpos SIZE MB). But if start second of the first ch...
Hi all, I am currently trying to read in video frames by using FFMPEG. The format is PIX_FMT_RGB24; For each frame, the RGB values are all combined together in frame->data[0] (Where frame is of the type AVFrame). How do I extract the individual R, G and B values for each frame? This is for processing the video. I would think it would ...
I'm wondering how to use FFMpeg to grap the middle frame of a video. I've already written the C# to grab a frame at a certain time (ie pull one frame at second 3). But I've yet to figure out how to find the middle of video using the FFMpeg commands. ...
In iPhone OS 3, Apple has introduced HTTP Live Streaming which should allow live streaming of video from the internet. I am currently operating a webcam, which feeds into my server, and is then converted into a flv stream by ffmpeg, and streamed back out using ffserver.

I have an oddly difficult task to perform. I thought it would be easy, but all my efforts have been fruitless. I'm converting videos uploaded to a php script from various formats (.avi, .mpg, .wmv, .mov, etc.) to a single .flv format. The conversion is working great but what I'm having trouble with is the resolution of the videos. Th...
I need to read the output from ffmpeg in order to even try the solution to my question from yesterday. This is a separate issue from my problem there, so I made a new question. How the heck do I get the output from an ffmpeg -i command in PHP? This is what I've been trying: <?PHP error_reporting(E_ALL); $src = "/var/videos/vi...
hi all, I'm trying to read a real-time http video stream (I've set one up using VLC and my webcam) using libavcodec from ffmpeg. so far I've been able to read an mpeg file fine but when I pass a url instead of the file name it hangs (I assume it's waiting for the end of the file). anyone have experience/ideas on how to do this? I'm a...

I am wanting to use ffmpeg to convert video to .flv in php. Currently I have this working, but it hangs the browser until the file is uploaded and is finished.

Here's the situation. While uploading a video, I want to capture a screenshot of that video and save it as a video thumbnail. I currently can't install ffmpeg on my local machine (it will be installed on the production server of course) so I cannot test the following controller action helper I wrote for this purpose: <?php /** * FlvThu...
Hi; I'm trying to build a C++/CLI executable to which I statically link ffmpeg (libavcodec, libavformat, libavutil & swscale). It works fine if I build it normally (without /clr, so no CLR support), it works. However, when I add CLR support, it won't start up with a 0xc000007b. A "Hello World" C++/CLI app runs fine, though. Supposedly t...
Hi, I'm looking for a way to playback .flv files using java. This means I will need a ffmpeg lib that is cross-platform. I've been toying with jmf and fobs4jmf, but I cannot playback in linux because I need a native library (maybe fobs4jmf.so?). Is there any java lib that allows me to playback .flv besides fobs4jmf? Or fobs4jmf can be ...
