Streaming video from an image using FFMPEG on Windows
26 mai 2013, par Daniel ZoharI wrote a program that simulates a camera and converts the output into a video stream. The program is required to be able to run on Windows.
There are two components in the system :- Camera Simulator. A C++ program that simulates the camera. It copies a pre-generated frame (i.e. PNG file) every 0.1 seconds, using the windows
copycommand, to a destination path./target/target_image.png - Video Stream. Using FFmpeg, it creates a video stream out of the copied images. FFmpeg is ran with the following command :
ffmpeg -loop 1 -i ./target/target_image.png -r 10 -vcodec mpeg4 -f mpegts udp://127.0.0.1:1234
When running the whole thing together, it works fine for a few seconds until the ffmpeg halts. Here is a log while running in debug mode :

ffmpeg "Header Missing" error recoding mp3 files
26 juin 2012, par Jonathan CoeI have an mp3 encoding server running on Ubuntu (natty). This has been working perfectly up until maybe a week or two ago. I believe I ran an update, which seemed to break the encoder for me - every time I try to run the encode script, it fails out with the error "Header Missing". Files that encoded previously without any issues no longer encode.
I am getting the following output when I run a basic ffmpeg script (that worked fine previously). Any ideas what is going on ?
