passing commands to FFMpeg

Post by scotty69169 »

I got FFmpeg to see my camera correctly and write a file. But I had to use the following command line:

ffmpeg -loglevel debug -rtsp_transport tcp -i "rtsp://admin:123456@192.168.90.112:554/profile2/" -c:v copy -c:a aac -max_muxing_queue_size 99999 -map 0 foo.mp4

Is there a way to pass some of the commands to FFmpeg. Like "-c:a aac", Because my IP camera is using a none supported audio codex(pcm_alaw).

Thanks,

Scotty

RVMedia does not support reading sound using FFMpeg yet.
It only supports sound from microphones or other local devices.

Hi Sergey, 'yet' implies that you're planning to add this feature. Is that right? I think that would be awesome.

Yes, reading sound using FFmpeg is planned in future.

But I do not know when it will be implemented, because our next goal (after releasing RVMedia 6) will be FireMonkey and other platforms.

Regarding the original subject of the post: "passing commands to FFMPeg"
In spite that the sound options wanted by Scotty are not supported, is there any way to pass extra parameters to RVMedia affecting the video, for example the ones to resize video or change aspect ratio of the sort:

-hide_banner -x 640 -y 480 -noborder -vf scale=640:480

Thank you.

Some parameters can be passed to FFmpeg by assigning sub-properties of RVCamera.FFMpegProperty .
