This CL creates an unique temporary filename for each video. Bug: webrtc:10156 Change-Id: Ie3abf85abdfa95735cb86880bbd6a59393e609c1 Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/127883 Reviewed-by: Mirko Bonadei <mbonadei@webrtc.org> Reviewed-by: Niels Moller <nisse@webrtc.org> Reviewed-by: Paulina Hensman <phensman@webrtc.org> Commit-Queue: Yves Gerey <yvesg@webrtc.org> Cr-Commit-Position: refs/heads/master@{#27219}
