I want to cat a /dev/video0 device output (Transport Stream) into a temporary ring buffer. In fact i do not want that the file is growing over the time. Simultaneously access is not possible.
So the purpose is to have a file (buffer, Fifo, whatever) to be accessed by more than one consumer (example: tail -f, mencoder, VLC, ....).
Some kind of scenario:
1# cat /dev/video0 > mybuffer.ts
And then multiple access
2# tail -f mybuffer.ts > extract1.ts
2# tail -f mybuffer.ts > extract2.ts
3# ffmpeg ...
Does someone have an idea how to do something like this?
