JustStream features at a glance:

**Supports a huge variety of video formats**

JustStream can work with pretty much any media file type, including the popular AVI, FLV, MKV, 3GP, MP4, MKV, MOV, AVI, WMV, MP3, WAV. The greatest thing about JustStream is that even if your movie format is not supported by a device you are streaming it to, the app can convert it on the fly. No need to search the web for conversion options and wait for hours - JustStream will smoothly run the conversion while you are already enjoying your content. Thanks to the full native M1 support on Apple Silicon Macs video conversion is much lighter on the CPU.

JustStream will effortlessly pick up both external and embedded soundtracks while streaming.

**Pause/Resume at your convenience**

Good quality but just has to long of a wait time.

I enjoyed how I could get my computer screen up on my TV, but there is a long delay on the screen. Even switching tabs takes forever! It would be a much better app if they could fix this.

Why do you invoke ffmpeg for sound capture?

I noticed that when I install the sound capture driver and cast, ffmpeg runs in the back with nearly 90% CPU usage. My bet is you guys recycled sounflwower, but instead of handling the transcoding you invoke an ffmpeg binary. I feel like a better alternative can be implemented.

Choppy Audio

Downloaded this app a few months ago and audio was horrible. Redownloaded and gave it another try and audio was still extremely choppy. Thankfully found another app that has better audio integration. Wished the audio would've worked because the video mirroring was tolerable; only a 3s expected delay with video. The audio however was terrible

Developer Response ,

In most cases, the hardware bandwidth (TV specifications) does not let the stream of the 'heavy' videos through. In order to resolve the issue, please click the JustStream icon on the top menubar -> click the cogwheel icon and select ‘Preferences’ -> please uncheck the “Use native playback when supported” option on the Streaming tab in JustStream Preferences and restart the playback after rebooting your Mac and Wi-Fi router. Please do the following as well: find and force 720p streaming.
