mpegts: stop analyzing when pmt for all programs have been found · 6eda91ad

Joakim Plate authored Dec 15, 2013

This disables NOHEADER after finding PMT for all programs to
avoid find_stream_info always exhausting probe size for mpegts.

This is very important for live streams since read speed
will be limited. rtsp, udp and any protocol streaming a live
mpegts will have dramatically faster startup time.

Note, lack of codec parameters for streams can still cause
the full probe size to be exhausted.
