Stream output to memory buffer

[MrMarble]

Is there a way to get the output stream?

I'd like to buffer some video for manual playing, currently I use --sout #std{mux=ts,access=file,dst=-} to output the data to the console and capture it manually to then use it as a buffer.

It would be better to access the stream directly, like with https://wiki.videolan.org/Documentation:Modules/smem/, but I'm not sure on how to do it (or if it's even possible)

Yes, you can use the smem module to capture the output stream directly into memory. Here's the approach:

vlc input_file --sout "#transcode{vcodec=RV24,acodec=s16l}:smem{video-prerender-callback=video_callback,audio-prerender-callback=audio_callback}"

You’ll need to implement the video_callback and audio_callback functions to handle the stream data. These callbacks give you direct access to the video and audio buffers in memory for manual processing. This avoids writing to the console or a file.
