ANN: RVMedia 7

Is Gstreamer 1.0 supported or only the very very old (ancient) Gstreamer 0.1 Version ?! (Linux-x86-64  & Win64)

[Sergey Tkachenko]

Currently, only GStreamer v0.1. We plan to add v1.0 support in future updates, but I cannot tell the date yet.

Can you please recompile all the demo packages with the option -Ur activated. This should avoid the recompile.


See thread https://forum.lazarus.freepascal.org/index.php/topic,47582.msg340981.html#msg340981 for information.

I recompiled Linux trials with this option: https://www.trichview.com/rvfiles/rvmedia/RVMediaTrialLazarusLinux.zip

Sergey can you please check with ppudump if your files have the flag 'release' set. I have the same ppu error like before and the flag for release is not found in the ppu of  MRVInet (and the other ppu).

I think some is gone bad and the -Ur is not accepted at recompile.

I fixed the files and re-uploaded to the same location.

THX for help, but it looks it is actual not possible to create useable package without source in Lazarus and to share this between differnt installation.

For reference: https://forum.lazarus.freepascal.org/index.php/topic,47582.msg341813.html#msg341813

No problem actual for me, because i have bought one version with source in the meantime :-)

We've released RVMedia 7.2: components that can display video from various (local and remote) sources, can control camera properties and movement, record audio and video, organize video chats.
RVMedia is available for Embarcadero Technologies Delphi and C++Builder (as VCL and FireMonkey for Windows), and for Lazarus (Windows and Linux).

In this update we impoved support for local cameras (USB or built-in webcams) in Windows:
- we added a new component that displays a dialog for editing local camera properties
- the components can rotate local cameras (of course, if they support rotation)
- you can change properties of local webcams in code;
- more video modes are supported (because now we decode video frames themselves).

For IP cameras and video streams, we improved and fixed authentication procedure. A new dialog is added to request user name and password.

Dialogs (and all messages) in RVMedia can be displayed in English, French, German, Portuguese (Br), Spanish, Russian, Chinese languages (contact me if you want to display them in your language)

Unfortunately, but we decided to abandon Lazarus trials (they seem to be useless, because it looks like every recompilation of a unit changes its checksum).

I have compiled with RVMedia 7.1 sucessfull with Lazarus on Win32, Win64, Linux64 and RasPi Buster.

ffmpeg looks ok. gstreamer support is ancient version 0.10, not available on modern linux versions.

the sources are complete and it is possible to fix small issues. Sergey fix very fast  if you find a feature. THX for the great software.

[Sergey Tkachenko]

We updated RVMedia to v7.3.

Since this update, it can use GStreamer 1.0 to play videos.
