AVISYNTH LINUX UPDATE

The most common construct is probably vs.get_core() that no longer works.

Many script functions were marked as obsolete or removed.

COMPAT formats вЂ“ existed to make loading Avisynth plugins possible but in the 9 years or so since the first release Avisynth+ has appeared and just about all Avisynth filters support planar formats so itвЂ™s pointless and adds complexity to core functions).

YCoCg вЂ“ never became popular and everything else treats it as degenerate YUV so now we do too).

While the core itself is more or less fully compatible with the old API a few features were removed which can cause issues with less than 1% of all plugins. Compatibility and breaking changesДЄs usual with all big updates there are breaking changes to clean up past mistakes and remove unused features. Note that as a general rule script memory usage decreases with the number of plugins used that are updated to the new API version. The memory usage has also been greatly reduced and a scripts like QTGMC (once again) will usually no longer reach the upper limit and warn about memory usage. Almost nobody uses variable format in video and it keeps the complexity down.ДЄ lot of work has gone into improving performance and scripts like QTGMC can run up to 10% faster on modern CPUs.

Audio canвЂ™t have variable sample rate or format.

Frame properties are not really a thing due to audio frames in VapourSynth being an arbitrary lump of samples.

Note that these always use index 0 for video and 1 as audio source.

Audio output with video in VFW and AVFS can be done with t_output(1).

Simple, right? So instead IвЂ™ll list the biggest points. In addition to video nodes there are now audio nodes. AudioДespite being a fairly big feature there isnвЂ™t that much to say about audio. Finally Avisynth(+) is truly obsolete and the remaining 5 audio users can safely migrate.

AVISYNTH LINUX UPDATE

After years of development the next major update to VapourSynth is ready.
