Re: Reduce latency for RTSP streams

In version 8.0 that I have here, the name changes from NoDelay to TcpNodelay I think TcpNoDelay and NoDelay are dealing with distinct aspects of the system. TcpNoDelay is a network flag (available in 8.0) while NoDelay is a decoding flag (available from version 10.3). So version 10.3 is the way to ...

Re: Reduce latency for RTSP streams

After commenting those pair of lines and recompiling packages (yes, I'm compiling for Win64) I can confirm latency is gone. RVMedia now is performing as good as the proprietary software, even when showing multiple streams simultaneously.
Thank you Sergey.

TRVAudioPlayer not working with default input device index

When trying to activate a TRVAudioPlayer whose AudioOutputDeviceIndex is -1 (default) a "Range check error" occurs. To avoid this an explicit (>=0) input device index must be specified e.g.

Code: Select all

RVAudioPlayer1.AudioOutputDeviceIndex:=0;
Then activation works as intended.

Hi. I'm trying to build a simple audio recorder by using TRVMicrophone, but including this component on a blank FMX project causes it to crash. This was tested for Windows platform, using Delphi 11.3 and RVMedia FMX version 9.3 with source code. When running the blank project with debugger it shows ...
