Are you looking for a free encoder? If so, please note that we recommend OBS Studio rather than Adobe FMLE, as it’s a more reliable software. However, we do still support both encoders. Adobe FMLE can be a good solution if you intend to do multi-bitrate streaming. For that reason, we’re offering this Adobe FMLE-focused streaming guide.

15) FOR MULTI-BITRATE STREAMS: Do you plan to do multi-bitrate streaming? If so, you need to replace “150” with “%i” in the stream name of your live channel.
For example: dclive_1_150@XXXXXX => dclive_1_%i@XXXXXX

16) At this point, click on Connect. Enter the login (username) and password you wrote down earlier (see step 11).

17) Before launching the stream, make sure you have a Keyframe frequency of 2 seconds (and nothing else) when clicking on the format settings. You should select the following settings (see screenshot below):

18) Finally, click on Start. You are now ready and able to stream!

Want to preview your stream? Return to the DaCast backend and click on Preview.

Note that it can take up to 50 seconds to come up online for “All devices” channels. Be patient, and your stream preview should load within a minute or so.
