Version History

Version 20.3.25 of Procaster

Procaster version 20.3.25 is now available for download!

We've made some improvements to Procaster that makes the software more reliable and functional. These updates mostly improve functionality, but we've added a couple new features as well. Here are the changes:

    • Fixed crashes when Memory gets low. This makes the application more reliable.
    • Better stability when cameras have a fluctuating frame rate. When using cameras with different frame rates, Procaster is now more reliable.
    • Fixed disconnect/reconnect in Blackmagic cards and H.264 recorder. Procaster now reconnects to Blackmagic cards properly.
    • Fixed several time issues with Blackmagic cards. Makes Procaster more reliable with Blackmagic cards.
    • Memory Leak fixes. Improves performance.
    • Fixed audio format detection with certain Blackmagic Devices. Audio will now be detected and play properly.
    • Fixed camera settings storage.
    • Audio Mixer is now displayed on the same screen as control bar when live. Makes mixing easier when live.
    • Removed "Matrox A/V Input" DirectShow device from the sources list. Sometimes duplicate inputs and extra inputs would appear in the sources list. Now they will not.
    • WAS (Vista and higher) Recording Fix (looping sound). There was an issue where sound would sometimes loop, which is now fixed.
    • Fixed an issue with the Microsoft Lifecam Cinema where it would stop streaming with extreme light changes. During broadcasts that involve drastic changes in lighting, streams would stop. That will no longer happen.
    • Removed NTSCp, PALp and 720p half-FPS video modes from the capture methods of Matrox capture devices. These video modes were unreliable and have been removed.
    • Fixed a bug when the username on Windows is not in the English alphabet. Procaster would not be able to start with usernames that were not in the English alphabet. Procaster will now open properly.
    • Added game rehooking (By default ctrl+f2). You can now rehook your game with this keyboard shortcut.
    • Fixed several game hooking so it is more reliable. Hooked games would not be able to be broadcast or would sometimes drop out.
      • Some example games: Counter-Strike: Source, Half-Life 2: Deathmatch, Garry's Mod, Day of Defeat: Source, Team Fortress 2, Dota 2 Beta

Version 20.3.0 of Procaster

Procaster version 20.3.0 is now available for download!

Livestream Procaster 20.3.0 Release Notes The Livestream Procaster 20.3.0 release is focused on stability and bug fixes.

Notable Bug Fixes and improvements:

    • Procaster was crashing with the latest BlackMagic Decklink Driver version 9.5. We fixed this to ensure Procaster will no longer crash when using the latest BlackMagic Decklink Driver Version 9.5.
    • Procaster would sometimes stop with "Capture Card Async Detected Errors" We made improvements to ensure this will no longer occur.
    • We added a new feature that gives the ability to select your own input aspect ratio.
    • We added a new feature that enables the Livestream Procaster window to stay "Always on top." After installing Livestream Procaster, this feature is set to off by default. The ‘Always on Top’ feature can be turned on in the Preferences dialog on the Desktop Tab.

Full list of bug fixes and improvements:

      • Previously the hotkeys could start a broadcast while the Preferences dialog was open. Procaster 20.3 will not allow a broadcast to start while Preferences dialog is open.

This version features

    • Major video and audio quality improvements with improved bit rate usage control
    • Perfect Audio/Video Synchronization live and on-demand. Previous versions had various issues with lipsync during long encoding sessions
    • Reduced CPU usage when streaming
    • Stream at higher bitrate over the same Internet connection: Improved the connection usage, so that you can utilize utilize your connection more efficiently.
    • New easy to understand status message in the control bar with suggested solutions :
      • “Perfect Streaming” means that your stream is being sent to the Livestream server perfectly. No lag and no connection or CPU issues.
      • “CPU above 80% try closing other apps or stop lower quality” means that your CPU usage is above 80% and that you should close some other applications. When your CPU reaches 100%, Procaster may stop broadcasting.
      • “Internet too slow for quality avoid shared connections or stop and lower quality” means that Procaster is not getting the full bandwidth it needs to stream and you should lower the quality of streaming in the main window.
      • “Lost internet connection. Attempting to reconnect. Local MP4 still recording.” Means that your internet connection fully dropped and that Procaster is trying to reconnect. The local recording will always keep recording.
      • The CPU usage is also now shown in the control bar now.
    • New behaviours to better handle connection bandwidth fluctuation and drops :
      • Anti lag feature - When enabled (default), it will keep the delay between you and your viewer, up to a maximum of 10 seconds. The local MP4 file recording will always have all the frames, even if anti-lag kicks in
      • Continue to encode and record locally even when the internet connection is dropped - When your internet connection suddenly drops, Procaster will continue recording and will go live again once you have regained connectivity. This can also be used to switch from one internet connection to another when experiencing an issue.
    • HD Multi-bitrate Support on browser and mobile devices:
      • You can now select qualities to stream at two, three or four bitrates at the same time (If you have enough resources - CPU/Memory/Bandwidth etc…).
      • The new Livestream Player now offers the ability for the user to select any of the streams you are publishing from Livestream Procaster.
      • When viewing your live stream on iPad and iPhone devices, the bitrate is automaticallyt selected (adaptive) based on the viewers connection and the number of qualities you are encoding from Procaster.
      • Note: This only currently works with live streams, the recorded stream will be the main default stream (typically a 450-600Kbps stream)
