avfoundation - Getting and setting playback position AVAudioEngine -

-

वापस जब AVAudioPlayer का उपयोग किया गया था, तो currentPosition का उपयोग किया जाता था & amp; स्थिति सेट करें, लेकिन जब AVAudioEngine & amp; AVAudioPlayerNode का उपयोग किया जाता है?

AVAudioEngine AVAudioPlayer से अधिक जटिल है। इसलिए मौजूदा स्थिति को जानने के लिए आपको नमूना टाइम / नमूना का उपयोग करना चाहिए नमूना टाइम AVAudioPlayerNode के अंतिम रेन्डरटाइम में पाया जाता है और sampleRate AVAudioFile की फ़ाइल स्वरूप में पाया जाता है।

इसके अलावा, यदि आप वर्तमान स्थिति को सेट करना चाहते हैं, तो आपको प्लेयर में डेटा स्ट्रीम करने के लिए एवाडियओपीसीबीफ़ेर का उपयोग करना होगा। फिर फ़ाइल सूचक को आगे बढ़ने के लिए AVAudioFile की फ्रेम रचना संपत्ति सेट करें का उपयोग करें।

c++ - Cassandra datastax cpp driver - avoiding unnecessary copies -

-
I use the following method to create my insert statement for Cassandra (using datastax cpp driver) : ssStmt1 & lt; & Lt; "Insert some table (...) value (....)" string sStatement1 = ssStmt1.str (); Castestring cass1 = cass_string_init (sStatement1.c_str ()); CassStatement * pStmt1 = cass_statement_new (cass1, 0); I have also tried the following: CassString cass1 = cass_string_init ("Enter some table (id, date, c) value (? ,?,?); "); CassStatement * pStmt1 = cass_statement_new (cass1, 3); Cass_statement_bind_uuid (pStmt1, 0, uuidKey); Cass_statement_bind_int64 (PSTMT1, 1, timestamp); Cass_statement_bind_string (pStmt1, 2, sSomething); The first pattern works with mixed keys, the second is not. The key has a timestamp and a UUID. Timestamp is one of two errors in the field (based on the used bond statement). If bound in this way: cass_statement_bind_int64_by_name (pStmt1, "date", timestamp); I get the following error: Inva...
