Hello,
I am writing an application using QtGstreamer library.
I am implemeting a media player application. i am using Appsource for linking the source. The data is available in a char *buffer.
I created a buffer using QGst::Buffer::create(size).
// pBuf has the Transport stream data char *pBuf
// This piece of code is in a loop.
QGst::BufferPtr m_buffer;
m_buffer=QGst::Buffer::create(buf_size);
quint8 *m_data_ptr=m_buffer->data();
memcpy(m_data_ptr,pBuf,buf_size);
if(this->m_player->m_pipeline);
ret = this->m_player->m_appsrc.pushBuffer(m_buffer);
if (!m_buffer.isNull())
{
if (ret != QGst::FlowOk)
{
/* some error, stop sending data */
qDebug("some error");
}
else
{
qDebug("pushed a buffer successfully");
}
}
The method works, i am able to display the video. However, I did not know how to release the buffer created. so the application leaks memory. How to release the Buffer, after pushBuffer. Please help.
Thanks and regards
Trinadh
