xine-lib/src/audio_out, branch 1.1.21

Remove ALSA resampler bypass

2012-02-01T02:45:20+00:00

In 2005, xine-lib 1.1.1 added the following change:

xine-lib (1.1.1) 2005-11-15
  * Improve sound quality when using alsa 1.0.9 or above.
    When playing a 44.1khz stream on a 48khz only capable sound card.
    It bypasses alsa-lib resampler and uses xine's

That made sense when Alsa's resampling was the worst thing ever.  But now,
if one installs alsa-plugins-1.0.25 and puts this in ~/.asoundrc:

defaults.pcm.rate_converter "samplerate_best"

Alsa then does markedly better resampling (using libsamplerate) than
xine-lib (using its own algorithm).  The bypass added in 2005 is therefore
preventing the use of a higher-quality algorithm and blocking the ability to
tune that algorithm in ~/.asoundrc, and no longer seems to have any
redeeming value.

Fixed small typo in src/audio_out/audio_directx2_out (LP #810407)

Prefix open_cloexec() and create_cloexec() with xine_, and add new xine_socket_cloexec() function.

2011-10-03T11:11:56+00:00

Mark simple file and socket descriptors as uninheritable.

2011-10-01T13:14:27+00:00

This patch creates two utility functions:

  int open_cloexec(pathname, flags)
  int create_cloexec(pathname, flags, mode)

These return a file descriptor with the CLOEXEC flag set, to ensure
that the descriptor is not inherited across a fork/exec operation.

The sockets returned by:

   _x_io_tcp_connect_ipv4()
   _x_io_tcp_connect()

now also have their CLOEXEC flag set.
