[Live-devel] Is memmove() necessary when using blocking call?

[Avramoni, Sorin]

Hi,


So far I managed to successfully stream h264/h265 video, jpeg, audio and text using live555 from my video and audio encoders at the same time. I created a class that inherits FramedSource () and I am using event trigger to signal new frames from my threads and I implemented a mechanism with semaphores to wait for frame completion so basically I have a mechanism of blocking api.


I know that live555 uses memmove() and memcpy() to put frames into buffers. First I do a memmove() into my class that inherits FramedSource() to put into 'fTo', this is done for all sessions, then H264or5Sink does a memmove() also Text sink does it, also freeBSD 'sendTo()' uses memcpy() to immediately releasing the buffers. In my case this induce a lot of processor effort because sometimes metadata that I feed into text session is Mbs per frame, I am wonder since I have a blocking mechanism it is possible to not use memmove() and just use a reference to my buffers?

Thank you!
Sorin.
