ffxvid for Linux/BSD

[microchip8]

I've received a number of requests from people who asked for a script that helps to encode to Xvid, so here it is. It's a modified script of ffx264 for Xvid encoding with FFmpeg

https://sourceforge.net/projects/ffxvid/

Enjoy

[microchip8]

ChangeLog for ffxvid 1.0.9

* Added support for FFmpeg's internal Opus audio encoder

[microchip8]

ChangeLog for ffxvid 1.1.0

* Simplify the scale variable a bit
* Support SMPTE170M colorspace conversion

[microchip8]

ChangeLog for ffxvid 1.1.1

* Match software scaler options in config file with the ones inside the script. $SCALER in config file now takes a value between 0 and 9
* Do some basic checking of scaler option when it's set in the config file

[microchip8]

ChangeLog for ffxvid 1.1.2

* Remove redundant software scaler warning and exit in the sws_func() function for the config file

* Removed additional encoder info on max audio channels support

[microchip8]

ChangeLog for ffxvid 1.1.3

* Report software scaler set in the config file
* Merge the bicubic and spline scaler tuning code
* Mention for the Lanczos scaler that the scaler tuning value is the filter length and not sharpness

[microchip8]

ChangeLog for ffxvid 1.1.4

* New function, video_chars_func(), to detect and display video characteristics like color range/space/transfer/primaries
* Detect and display video resolution if video scaling is enabled

* Some small improvements to the video_colorspace_func() function

[microchip8]

ChangeLog for ffxvid 1.1.6

* Bugfix in the video_colorspace_func() function. Wrong value used for the ispace option of the filter. Must be bt2020ncl instead of just bt2020

[microchip8]

ChangeLog for ffxvid 1.1.7

* Make software scaler tweaking optional
* Added support for the unsharp filter for sharpen/blur
