This is the same codec, but now it will be used with a fixed bitrate, which is better suited for streaming. You can get around this by setting the codec to 'Other', and then choosing 'libx264'. This is great for normal recording, where you only care about the total file size, but not so much for live streaming. This means the bitrate will vary depending on the complexity of the video. If you're using H.264, SimpleScreenRecorder will by default use 'constant quality mode'. The most common codecs are H.264 for video and AAC for audio (this works for flv and mpegts). The codecs you can use are limited by the container that you're using. Some media players (VLC, ffplay) appear to be unable to play flv streams that have no audio. Wait at least 30 seconds before concluding that it doesn't work. During this period you may even get error messages (e.g. In many cases, it takes some time before a stream starts playing, because the player has to wait for a keyframe. Matroska also appears to work, but not all players support it. Containers that are known to work are 'flv' and 'mpegts' (found under 'Other'). MP4) put important metadata at the end of the file, so if you try to stream those files, you won't see anything. Not all containers are suitable for streaming. If possible, try to get the latest version of ffmpeg/libav (ffmpeg is preferred if you have a choice). If you can't connect, check your firewall (for RTMP, ffmpeg/libav may kill the process without any error message if the connection is refused). Make sure you have a reliable internet connection. These won't show up in the log in SimpleScreenRecorder. Run SimpleScreenRecorder from a terminal, so you can see error messages produced by ffmpeg/libav or other libraries. Don't be surprised if SimpleScreenRecorder closes or freezes without any explanation. RTMP streaming (explained below) appears to be reliable, but many other protocols and containers are not. Unfortunately, the streaming support in ffmpeg/libav isn't nearly as robust as the rest of ffmpeg/libav.
