http stream is stopping after a few seconds

[Marcel Behlau]

Hi,

thx for your help. A lot of streams are working fine, but some streams 
(which are requested by my customer) are failing with this problem.

I think the problem is related to buffering/caching, which isn't optimal 
for this kind of stream/some server configurations. It seems, there is 
some kind of an hiccup, so that the data isn't provided in a very smooth 
manner.

Regarding this, i tried to increase the buffer sizes to create an data 
pool for compensating the "data downtime".

If i use the following command, gstreamer is fetching a long, long time, 
before starting the playback. Unfortunately, the stream is stopping also 
after a few seconds. What is happening during in the fetching phase?

gst-launch-1.0 --gst-debug=uridecodebin:5 uridecodebin 
uri=https://d2e1asnsl7br7b.cloudfront.net/7782e205e72f43aeb4a48ec97f66ebbe/index_5.m3u8 
buffer-duration=30000000000 buffer-size=100000000 download=true 
use-buffering=true high-watermark=1.0 low-watermark=1.0 ! autovideosink


Btw. i found an workaround by fetching the data with ffmpeg. This can be 
done via this one-liner:

|ffmpeg -i 
https://d2e1asnsl7br7b.cloudfront.net/7782e205e72f43aeb4a48ec97f66ebbe/index.m3u8?checkedby:iptvcat.com 
-codec copy -f hls - | gst-launch-1.0 fdsrc fd=0 ! decodebin ! 
autovideosink|

|This seems to work fine, but i would like to avoid the extra ffmpeg 
command.
|

|Thanks in advance,|

|Marcel
