Martin Storsjö eb061ad6fd tls_gnutls: Readd support for nonblocking operation 
The rtmp protocol uses nonblocking reads, to poll for incoming
messages from the server while publishing a stream.

Prior to 94599a6de3 and
d13b124eaf, the tls protocol
handled the nonblocking flag, mostly as a side effect from not
using custom IO callbacks for reading from the socket. When custom
IO callbacks were taken into use in
d15eec4d6b, the handling of a nonblocking
socket wasn't necessary for the default blocking mode any longer.

The code was simplified, since it was overlooked that other code
within libavformat actually used the tls protocol in nonblocking mode.

This fixes publishing over rtmps, with the gnutls backend.

Libav

Build Status

Libav is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

  • libavcodec provides implementation of a wider range of codecs.
  • 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.
