Good afternoon Ross, I am having a bit of trouble supplying live data to live555. I have encapsulated my live source using the DeviceSource code as a base. I know you can't help with modified code, and that's fine. I just have a simple theoretical question: When using the delayed EventTrigger functionality of DeviceSource (TaskScheduler->signalDataWaiting(eventTriggerId, ...) I seem to be unable to send a complete frame. I am using an MPEG4ESStreamFramer which allows me to supply frame chunks when my live source is updated and data becomes available, however live555 fills an internal buffer with as many chunks as it can before sending the chunks off in a single sendto call. All of the behaviour described so far is great, but my deliverFrame function is not called for the last chunk of my frame. I have tried triggering the TaskScheduler event from within deliverFrame, but that results in undefined behaviour (access violation). Could there be another method of making sure that the last frame chunk is not discarded? I understand that there is the option to use a MPEG4DiscreteStreamFramer which allows for passing entire frame chunks at a time, but that approach fails miserably because of a socket send buffer limit. Is there any way I can send off parts of the complete frame I have using a stream framer, while still being signalled from an external class that data is available? In other words - using an elementary stream framer with discrete frames. Thank you Regards ___________________________________
