Cutting the stream on local date time when scheduled
19 juin 2017, par FearhunterI am using a ffmpeg slice commando in my C# code. For example : I scheduled a stream from 12pm till 3 pm. In my if statement I use a condition to compare the local datetime with the time of now.
DateTime systemDate = DateTime.Now;
DateTime compareDate = DateTime.Today;
private Process SliceStream(string url)
{
if (systemDate < compareDate)
{
return Process.Start(new ProcessStartInfo
{
FileName = "ffmpeg.exe",
Arguments = $"-i \"{url}\"-acodec aac -strict -2 -vcodec libx264 -hls_wrap 100 -f hls -hls_time 20 C:/var/1.m3u8 ",
UseShellExecute = false,
RedirectStandardOutput = true
});
}
else
{
Thread.Sleep(100);
return null;
}
}The problem is it doesn’t work when my time on my computer is for example 12pm and he is not cutting the stream.
What am I doing wrong ?

How to prevent overwriting fifo while playing local file with ffmpeg ?
21 juillet 2013, par frankishI use av_read_frame() to read and push frames to fifo. In another thread, I read from this fifo. So, reading and writing does not interfere that much.
However, I found out that when playing from a local file, audio suddenly skips to somewhere else.. I tried to open recorded file with VLC player and it worked. So the file(recording) is not broken.
I tried (just to see if it works) the following and it works but it has other problems.
...
if(localFile){
while(av_fifo_size(fifoPlayback)>2000000){
pthread_mutex_unlock(&fifoPlaybackMutex);
usleep(1000000);
pthread_mutex_lock(&fifoPlaybackMutex);
// Waiting before writing to fifo, it's not empty enough");
}
}
av_fifo_generic_write(fifoPlayback,...)Since the above block at least does not skip, I think my problem is really overwriting on the fifo. But how should I correctly manage this situation ?
