Description

splitmuxsink with mpegtsmux and curlftpsink is generating only one fragment and pipeline exits after displaying a timeout error with gst_poll_wait API.

After lots of experiments, I tried disabling the portion of code in the function "handle_transfer" of the file gstcurlbasesink.c of gst-plugins-bad where gst_poll_wait API is being used and GST_FLOW_ERROR is returned if no activity is found the concerned fd.

By disabling this, I could see the pipeline moving ahead and the fragments being generated at the target location.

I want to understand what gstcurlbasesink is exactly trying to do and why is it only after disabling this portion of code fragments are being generated.

Also, I observed one more thing. If I use mp4mux instead of mpegtsmux the pipeline just exits.
Please help me to resolve these issues. Any quick response is greatly appreciated.
