Constructor & Destructor Documentation

DynamicMJPEGStreamWebReply()

fawkes::DynamicMJPEGStreamWebReply::DynamicMJPEGStreamWebReply

(

WebviewJpegStreamProducer *

stream_producer

)

Constructor.

Parameters

stream_producer

stream producer to query for JPEG buffers

Definition at line 51 of file mjpeg_reply.cpp.

References fawkes::WebReply::add_header(), and fawkes::WebviewJpegStreamProducer::add_subscriber().

~DynamicMJPEGStreamWebReply()

fawkes::DynamicMJPEGStreamWebReply::~DynamicMJPEGStreamWebReply ( )

virtual

Destructor.

Definition at line 64 of file mjpeg_reply.cpp.

References fawkes::WebviewJpegStreamProducer::remove_subscriber().

Member Function Documentation

handle_buffer()

void fawkes::DynamicMJPEGStreamWebReply::handle_buffer ( RefPtr< WebviewJpegStreamProducer::Buffer >  buffer ) throw ( )

virtual

Notification if a new buffer is available.

Parameters

buffer

new buffer, simple unref when done.

Implements fawkes::WebviewJpegStreamProducer::Subscriber.

Definition at line 78 of file mjpeg_reply.cpp.

References fawkes::Mutex::lock(), fawkes::Mutex::unlock(), and fawkes::WaitCondition::wake_all().

next_chunk()

size_t fawkes::DynamicMJPEGStreamWebReply::next_chunk ( size_t  pos, char *  buffer, size_t  buf_max_size  )

virtual

Get data of next chunk.

Parameters

pos	position in the stream. Note that a certain position may be called several times.
buffer	buffer to store data in
buf_max_size	maximum size in bytes of data that can be put into buffer

Returns

number of bytes written to buffer, or -1 to immediately stop the transfer.

Implements fawkes::DynamicWebReply.

Definition at line 87 of file mjpeg_reply.cpp.

References fawkes::Mutex::lock(), fawkes::Mutex::unlock(), and fawkes::WaitCondition::wait().

size()

size_t fawkes::DynamicMJPEGStreamWebReply::size ( )

virtual

Total size of the web reply.

Return the total size of the reply if known, or -1 if it is not known. In the latter case your next_chunk() method has to return -1 at some point to end the transfer. If possible by any means return a meaningful value, as it will improve the experience of users, especially for long transfers!

Returns

total size of reply in bytes
