Martin Storsjö 15a92e0c40 rtmp: Correctly handle the Window Acknowledgement Size packets This swaps which field is set when the Window Acknowledgement Size and Set Peer BW packets are received, renames the fields in order to clarify their role further and adds verbose comments explaining their respective roles and how well the code currently does what it is supposed to. The Set Peer BW packet tells the receiver of the packet (which can be either client or server) that it should not send more data if it already has sent more data than the specified number of bytes, without receiving acknowledgement for them. Actually checking this limit is currently not implemented. In order to be able to check that properly, one can send the Window Acknowledgement Size packet, which tells the receiver of the packet that it needs to send Acknowledgement packets (RTMP_PT_BYTES_READ) at least after receiving a given number of bytes since the last Acknowledgement. Therefore, when we receive a Window Acknowledgement Size packet, this sets the maximum number of bytes we can receive without sending an Acknowledgement; therefore when handling this packet we should set the receive_report_size field (previously client_report_size).

libavformat implements streaming protocols, container formats and basic I/O access.
libavutil includes hashers, decompressors and miscellaneous utility functions.
libavfilter provides a mean to alter decoded Audio and Video through chain of filters.
libavdevice provides an abstraction to access capture and playback devices.
libavresample implements audio mixing and resampling routines.
libswscale implements color conversion and scaling routines.

Tools

avconv is a command line toolbox to manipulate, convert and stream multimedia content.
avplay is a minimalistic multimedia player.
avprobe is a simple analisys tool to inspect multimedia content.
Additional small tools such as aviocat, ismindex and qt-faststart.
