From 6c11fdfda7a0f306f894b15b56b72d3c4898013d Mon Sep 17 00:00:00 2001 From: Carl Hetherington Date: Sat, 16 Mar 2024 18:02:35 +0100 Subject: [PATCH] Allow SMPTE timecodes with 3 digits in the editable units field. It seems that these should only be present if the timecode rate is 101 or above, and in that case all timecodes should have 3 editable rate digits, but someone sent a DCP from what seems to be EasyDCP Creator and it has one timecode of 00:05:01:000. --- src/dcp_time.cc | 5 +++-- test/dcp_time_test.cc | 6 +++++- 2 files changed, 8 insertions(+), 3 deletions(-) diff --git a/src/dcp_time.cc b/src/dcp_time.cc index e21eaf27..f08f2b1c 100644 --- a/src/dcp_time.cc +++ b/src/dcp_time.cc @@ -147,7 +147,8 @@ Time::Time (string time, optional tcr_) } } else { - /* SMPTE: HH:MM:SS:EE */ + /* SMPTE: HH:MM:SS:EE[E]. + * It seems like there can be any number of E digits but let's just allow 2 or 3 */ split (b, time, is_any_of (":")); if (b.size() != 4) { boost::throw_exception (ReadError (String::compose ("unrecognised time specification %1; does not have 4 parts", time))); @@ -159,7 +160,7 @@ Time::Time (string time, optional tcr_) boost::throw_exception (ReadError (String::compose ("unrecognised time specification %1; %2 has bad length", time, b[2]))); } s = raw_convert (b[2]); - if (b[3].empty() || b[3].length() > 2) { + if (b[3].empty() || b[3].length() > 3) { boost::throw_exception (ReadError (String::compose ("unrecognised time specification %1; %2 has bad length", time, b[3]))); } e = raw_convert (b[3]); diff --git a/test/dcp_time_test.cc b/test/dcp_time_test.cc index 4b529be6..3e0050b4 100644 --- a/test/dcp_time_test.cc +++ b/test/dcp_time_test.cc @@ -131,6 +131,11 @@ BOOST_AUTO_TEST_CASE (dcp_time) /* SMPTE */ a = dcp::Time ("01:23:45:12", 250); BOOST_CHECK_EQUAL (a, dcp::Time (1, 23, 45, 12, 250)); + /* The editable units field can be any length (depending on the timecode rate) + * but in practice I think 3 is enough. + */ + a = dcp::Time("00:05:01:519", 250); + BOOST_CHECK_EQUAL(a, dcp::Time(0, 5, 1, 519, 250)); /* Check some disallowed constructions from string */ BOOST_CHECK_THROW (dcp::Time ("01:23:45:1234", optional()), dcp::ReadError); @@ -145,7 +150,6 @@ BOOST_AUTO_TEST_CASE (dcp_time) BOOST_CHECK_THROW (dcp::Time ("01:23:.123", optional()), dcp::ReadError); BOOST_CHECK_THROW (dcp::Time ("01::45.123", optional()), dcp::ReadError); BOOST_CHECK_THROW (dcp::Time (":23:45.123", optional()), dcp::ReadError); - BOOST_CHECK_THROW (dcp::Time ("01:23:45:123", 250), dcp::ReadError); BOOST_CHECK_THROW (dcp::Time ("01:23:45:123:66", 250), dcp::ReadError); BOOST_CHECK_THROW (dcp::Time ("01:23:45:", 250), dcp::ReadError); BOOST_CHECK_THROW (dcp::Time ("01:23::123", 250), dcp::ReadError); -- 2.30.2
