Recording generating huge files
Posted: 29 Jan 2018 17:27
Hi,
I need to develop an application that can record up to 10 rtsp streams coming from IP cameras to files.
I also need to be able to play this files while the recording updates them.
The VLC version is 2.2.6.
I have been trying different options strings passed to libvlc_media_add_option function.
std::ostringstream sStreamOption;
// Version 1
// Version 2
// Code to start recording.
This code will be ran in 1 thread for each stream.
When I use version 1 for the options, some of the streams are recorded properly, some of them generate huge file (it can reach a 1 GB very quickly), some others seems to be stopped. These huge files can't be played with any player.
When I use version 2 for the options, I have the same symptoms, plus the facts that I can't play the files while they are recording.
So I have the following questions :
- Can I execute this code from different threads?
- Which options do I need to pass to libvlc_media_add_option, knowing that no transcoding is needed?
Thanks for help!
