avformat/rtpenc: Fix integer overflow in NTP_TO_RTP_FORMAT
RTCP synchronization packet was broken since commit in ffmpeg version > 2.8.3
(commit: e04b039b1528f4c7df5c2b93865651bfea168a19) Since this commit (2e814d0329aded98c811d0502839618f08642685)
"rtpenc: Simplify code by introducing a macro for rescaling NTP timestamps", NTP_TO_RTP_FORMAT
uses av_rescale_rnd() function to add the data to the packet.
This causes an overflow in the av_rescale_rnd() function and it will return INT64_MIN.
Causing the NTP stamp in the RTCP packet to have an invalid value.
Github: Closes #182
Reverting commit '2e814d0329aded98c811d0502839618f08642685' solves the problem.
(cherry picked from commit 1109ed7973c7fd1e7001898adc4976590d862122)
