#ifndef DECODER_H
#define DECODER_H
Add stream layer The decoder initially read from the socket, decoded the video and sent the decoded frames to the screen: +---------+ +----------+ socket ---> | decoder | ---> | screen | +---------+ +----------+ The design was simple, but the decoder had several responsabilities. Then we added the recording feature, so we added a recorder, which reused the packets received from the socket managed by the decoder: +----------+ ---> | screen | +---------+ / +----------+ socket ---> | decoder | ---- +---------+ \ +----------+ ---> | recorder | +----------+ This lack of separation of concerns now have concrete implications: we could not (properly) disable the decoder/display to only record the video. Therefore, split the decoder to extract the stream: +----------+ +----------+ ---> | decoder | ---> | screen | +---------+ / +----------+ +----------+ socket ---> | stream | ---- +---------+ \ +----------+ ---> | recorder | +----------+ This will allow to record the stream without decoding the video.

Rename "frames" to "video_buffer" It better describes the purpose of the structure.

Update code style Limit source code to 80 chars, and declare functions return type and modifiers on a separate line. This allows to avoid very long lines, and all function names are aligned. (We do this on VLC, and I like it.)
