Playing video files using RVCamera

[TimR]

I have the following components:

TRVCamView
TRVCamera
TRVCamSound
TRVAudioPlayer

RVCamSound is connected to the camera and the audio player.

I'm using the FFMPEG library, but I have also tried with GStreamer with the same results.

I'm trying to play two video files. Both of them play in VLC with audio.

The first is a .MOV file from an old video camera. It plays perfectly but there is no audio.

The second is a .MP4 file from a new Samsung phone. It does not play at all.

Can you suggest anything?

There are no errors logged in the error handler.

I have tried all the options for RVCamera.VideoFormat and the results are always the same.

TRVCamera does not support playing audio using GStreamer. But FFmpeg must work.
Make sure that RVCamera.FFMpegProperty.Audio = True.
Can you send me a link to these video files?

First one (plays but no sound):

Any luck with these files?

I need more time, sorry.

Sorry again for the delay.

The first video (with the wind).
The problem: incorrect audio, playback jerks. I fixed it. The fix will be included in the next update (which will most likely be version 12.0). If needed, I can send you the fixed units for the current version of RVMedia (11.2).

The second video (with the helicopter).
I can't reproduce the problem. I tried both the compiled version of the Cameras\FFmpeg demo from the website (it's quite old though, from 2024) and the new version after the fix. It is played with sound.
