Description

hello i want to convert the example code of RecordActivity in kotlin but i can't translate the java code : ((ByteBuffer)yuvImage.image[0].position(0)).put(data); to kotlin i have this information : Classifier 'ByteBuffer' does not have a companion object, and thus must be initialized here

if i use the conversion code i have this result (yuvImage.image[0].position(0) as ByteBuffer).put(data)

and this error Cannot access 'org.bytedeco.javacpp.indexer.Indexable' which is a supertype of 'org.bytedeco.javacv.Frame'. Check your module classpath for missing or conflicting dependencies

Contributor guide

Research direction
Write the Java expression in Kotlin syntax, handling the ByteBuffer cast correctly. Inspect the javacv Frame class to understand the image structure and convert the line (ByteBuffer) yuvImage.image[0].position(0)).put(data) appropriately.
