[FFmpeg-user] Recording of German IP TV Channels fail after some time

[Claus Dietrich]

I wrote a Linux application which allows the recording of IP TV streams 
from the Internet through programmable timers. It works well but 
recording of the prime German TV channel "ZDF" always fails after some 
time (something between 5 to 120 minutes). The recording of other 
channels like "ARTE" also fail from time to time.

My application uses ffmpeg V 4.2.7 and the shell command:

ffmpeg -y -i 
http://zdf-hls-15.akamaized.net/hls/live/2016498/de/veryhigh/master.m3u8 
-vcodec copy -acodec copy /home/claus/out.ts

Using this as CLI command provides the same (bad) result. I never 
noticed any error message and the terminal activity always continued 
normally. The only indicator for failure was the output file which stops 
growing when recording fails.

Recording of ZDF and ARTE with VLC works reliable but is no option 
because of the much higher CPU and network load.

I would be very grateful if someone can help.

Best regards

Claus
