[pulseaudio-discuss] [PATCH v3 0/3] Libsamplerate resampler crash fix

[Tanu Kaskinen]

Here's a fix for https://bugs.freedesktop.org/show_bug.cgi?id=47156

Changes in v3:
 - More readable calculations, as suggested by David. Also
   fixed a couple of bugs in those calculations.
 - Rework the leftover storing, as suggested by Wang
   Xingchao: instead of using a dedicated buffer for it,
   store the leftover data in the beginning of remap_buf.
   This can avoid some memory copying.
 - Use a generic save_leftover() function instead of doing
   the leftover copying in the resampler implementor code.
 - Use the leftover logic also with the speex and ffmpeg
   resamplers.

Changes in v2:
 - Fixed bugs.
 - Better testing: I forced the resampler to always leave
   the last frame unprocessed. That uncovered one bug, but
   now the playback is smooth.
 - Sensible buffer names.

Tanu Kaskinen (3):
  resampler: Use pa_xnew0() to avoid manual zeroing.
  resampler: Use more descriptive buffer names.
  resampler: Add support for resamplers that consume less data than
    asked.
