From 67a1e19bed995d79721e4e5f0e24b6ffe304b4d5 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Tim-Philipp=20M=C3=BCller?= Date: Thu, 11 May 2023 16:25:11 +0100 Subject: [PATCH] qtdemux: add unit test for edit list regression File is the mp4 file from #2549 with the mdat atom zeroed out and compressed. We compress twice because apparently compressing 5MB of zeroes effectively in one run is too difficult for gzip. https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/2549 Part-of: --- .../tests/check/elements/qtdemux.c | 142 ++++++++++++++++++++- .../tests/files/editlists.mp4.gz.gz | Bin 0 -> 3597 bytes 2 files changed, 141 insertions(+), 1 deletion(-) create mode 100644 subprojects/gst-plugins-good/tests/files/editlists.mp4.gz.gz diff --git a/subprojects/gst-plugins-good/tests/check/elements/qtdemux.c b/subprojects/gst-plugins-good/tests/check/elements/qtdemux.c index 4a14c45..60c63aa 100644 --- a/subprojects/gst-plugins-good/tests/check/elements/qtdemux.c +++ b/subprojects/gst-plugins-good/tests/check/elements/qtdemux.c @@ -22,7 +22,25 @@ #include "qtdemux.h" #include -#include + +#include + +#include +#include + +#define TEST_FILE_PREFIX GST_TEST_FILES_PATH G_DIR_SEPARATOR_S + +static gboolean +load_file (const gchar * fn, guint8 ** p_data, guint expected_len) +{ + gsize read_len = 0; + + if (!g_file_get_contents (fn, (gchar **) p_data, &read_len, NULL)) + return FALSE; + + g_assert_cmpuint (read_len, ==, expected_len); + return TRUE; +} typedef struct { @@ -888,6 +906,127 @@ GST_START_TEST (test_qtdemux_pad_names) GST_END_TEST; +GST_START_TEST (test_qtdemux_editlist) +{ + const gsize editlist_mp4_size = 5322593; + guint8 *editlist_mp4 = NULL; + GstElement *src, *sink, *pipe; + GstSample *sample; + guint frame_count = 0; + + { + GZlibDecompressor *decompress; + GConverterResult decomp_res; + gsize bytes_read, gz_size, mp4_size; + guint8 *gz_gz = NULL; + guint8 gz[8705]; + + /* read .mp4.gz.gz */ + g_assert (load_file (TEST_FILE_PREFIX "editlists.mp4.gz.gz", &gz_gz, 3597)); + + /* mp4.gz.gz -> mp4.gz */ + decompress = g_zlib_decompressor_new (G_ZLIB_COMPRESSOR_FORMAT_GZIP); + decomp_res = g_converter_convert (G_CONVERTER (decompress), gz_gz, 3597, + gz, 8705, G_CONVERTER_INPUT_AT_END, &bytes_read, &gz_size, NULL); + fail_unless_equals_int (decomp_res, G_CONVERTER_FINISHED); + fail_unless_equals_int (bytes_read, 3597); + fail_unless_equals_int (gz_size, 8705); + g_object_unref (decompress); + g_clear_pointer (&gz_gz, (GDestroyNotify) g_free); + + editlist_mp4 = g_malloc0 (editlist_mp4_size); + + /* mp4.gz -> mp4 */ + decompress = g_zlib_decompressor_new (G_ZLIB_COMPRESSOR_FORMAT_GZIP); + decomp_res = g_converter_convert (G_CONVERTER (decompress), gz, 8705, + editlist_mp4, editlist_mp4_size, G_CONVERTER_INPUT_AT_END, &bytes_read, + &mp4_size, NULL); + fail_unless_equals_int (decomp_res, G_CONVERTER_FINISHED); + fail_unless_equals_int (bytes_read, 8705); + fail_unless_equals_int (mp4_size, editlist_mp4_size); + g_object_unref (decompress); + } + + fail_unless_equals_int (editlist_mp4[28 + 4], 'm'); + fail_unless_equals_int (editlist_mp4[28 + 5], 'd'); + fail_unless_equals_int (editlist_mp4[28 + 6], 'a'); + fail_unless_equals_int (editlist_mp4[28 + 7], 't'); + + pipe = gst_parse_launch ("dataurisrc name=src ! qtdemux name=d " + "d.video_0 ! appsink name=sink", NULL); + + fail_unless (pipe != NULL); + + src = gst_bin_get_by_name (GST_BIN (pipe), "src"); + fail_unless (src != NULL); + + sink = gst_bin_get_by_name (GST_BIN (pipe), "sink"); + fail_unless (sink != NULL); + + /* Convert to data: URI so we can use dataurisrc.
