[x264-devel] x264 Development Newsletter: Vol. 40

[Jason Garrett-Glaser]

This is the fortieth x264 development newsletter. This is a regular
email containing updates on fixes and improvements in the most recent
x264 push, along with updates on what's coming next.  Previous
versions can be found in the mailing list archives.

Fixes:

Work around an FFMS bug with empty index files.

Fix INSTALL in configure on Solaris systems.

Fix possible crashes in resize/crop filters on high bit depth input.

Fix shared library compilation on the original Windows MinGW toolchain.

Fix compilation in the case that the HAVE_LOG2F check fails spuriously.

Include dependency libraries in pkg-config generation.

Don't try to generate a .git version number on build if .git isn't
present (e.g. in snapshots)

Update code to the current libav/ffmpeg API.

Improvements:

Don't warn in non-verbose mode if VBV underflow occurs with CRF-max
(since the user likely wanted it to occur).

Slight speedup in chroma BI analysis.

Make encoder_reconfig more threadsafe: fixes some rare crash issues
with reconfiguring with frame threads.

Add a --filler option to generate streams with filler without using NAL HRD.

Add AVC Intra 1080p50/60 Class 100 parameters and some further AVC
Intra compatibility hacks/fixes.

Add L-SMASH support as a preferred alternative to GPAC for mp4 muxing.

Remove the --visualize option, as it is very old cruft and probably
does not work with many combinations of settings anymore (as it hasn't
been maintained).
