avformat/mov: avoid seeking back to 0 on HEVC open GOP files ab77b878f1 attempted to fix the issue of broken packets being sent to the decoder by implementing logic that kept attempting to PTS-step backwards until it reached a valid point, however applying this heuristic meant that in files that had no valid points (such as HEVC videos shot on iPhones), we'd seek back to sample 0 on every seek attempt. This meant that files that were previously seekable, albeit with some skipped frames, were not seekable at all now. Relax this heuristic a bit by giving up on seeking to a valid point (...)
