--- Comment #2 from Benoît Tarrade <benoittarr...@hotmail.fr> --- [Edit] : for now that's the stacktrace I have while profiling project loading with valgrind : ``` Frame: Backtrace for Thread 1 [ 0] read (103077 x) [ 1] QFSFileEngine::read(char*, long long) (101904 x) [ 2] QFileDevice::readData(char*, long long) (99246 x) [ 3] QIODevicePrivate::read(char*, long long, bool) (494613 x) [ 4] QIODevice::read(char*, long long) (375127 x) [ 5] qt_fill_input_buffer (373294 x) [ 6] jpeg_fill_bit_buffer (147621986 x) [ 7] decode_mcu (10730517 x) [ 8] decompress_onepass (35681 x) [ 9] process_data_context_main (568343 x) [10] jpeg_read_scanlines (568343 x) [11] read_jpeg_image(QImage*, QSize, QRect, QRect, int, void (*)(unsigned int*, unsigned char const*, int), jpeg_decompress_struct*, my_error_mgr*) (269 x) [12] QJpegHandler::read(QImage*) (269 x) [13] QImageReader::read(QImage*) (324 x) [14] QImageReader::read() (269 x) [15] refresh_qimage (269 x) [16] producer_qimage_init (269 x) [17] mlt_repository_create (665 x) [18] mlt_factory_producer (335 x) [19] create_producer.lto_priv.0 (335 x) [20] producer_loader_init (330 x) [21] mlt_repository_create (665 x) [22] mlt_factory_producer (270 x) [23] on_end_element (9016 x) [24] xmlParseEndTag1.constprop.0 (56694 x) [25] xmlParseElementEnd (56691 x) [26] xmlParseContentInternal (4 x) [27] xmlParseElement (4 x) [28] xmlParseDocument (2 x) [29] producer_xml_init (2 x) [30] mlt_repository_create (7 x) [31] mlt_factory_producer (2 x) [32] Mlt::Producer::Producer(mlt_profile_s*, char const*, char const*) (2 x) [33] ProjectManager::updateTimeline(bool, QString const&, QString const&, QDateTime const&, bool) [clone .constprop.0] (1 x) [34] ProjectManager::doOpenFile(QUrl const&, KAutoSaveFile*, bool) (2 x) [35] ProjectManager::openFile(QUrl const&) (1 x) [36] ProjectManager::qt_static_metacall(QObject*, QMetaObject::Call, int, void**) [clone .part.0] (2 x) [37] ProjectManager::qt_static_metacall(QObject*, QMetaObject::Call, int, void**) (1 x) ``` It's painfully slow due to the Debug build and underlying profiling, if I have the time to do so I'll try again with stopwatches for faster reporting. -- You are receiving this mail because: You are watching all bug changes.
