transcode

This release adds a specially-crafted import module targeting Webcams using libv4l. It fixes the colorspace detection in import_v4l2. In tcdemux, the built-in limit of streams selectable for passthrough has been dropped.
The x264 module has been fixed to work with libx264 >= 76. The video stabilization plugins have been updated to version 0.61. libmpeg2 is an optional dependency (libmpeg2convert is needed too).

This release fixes two recently reported critical bugs:
It fixes the build system to comply with autoconf 2.64.
It fixes bug: #16046.

Support was added for CubicKeys4 and Sinc8 zoom algorithms. Support was added for input selection and channel tuning into import_v4l2. This was backported from the 1.2.x branch. Spurious write warnings when using -y *,tcaud (a regression from 1.0) were fixed. Various bugs were fixed.

The -W option once again works like it did in the 1.0.x branch. The alpha data in filter_logoaway is properly handled (avoiding segfault). The outdated libav* information was removed from the FAQ. Other bugs were fixed. The x264 experimental encoder may now be built with the last libx264 snapshots. transcode may now be built without FFmpeg.

The import_imlist module is deprecated. Use --multi_input -x im instead. The dectectclipping filter is now allowed to use a log file. A big YAIT update was done. The "frame" option was added to filter_text. tcmodinfo linking and loading problems were resolved.
