When encode Videos with x264 from TS, x264 shows avs[error]: failed to load avisynth
The Output File has an extremly high Bitrate and the Picture is only image noise.
When I downloaded the Package Build from the Repo, x264 build fine without avisynth support and the encoding is fine.

Additional info:
* package version_: 3:0.157.r2980.34c06d1-1

Steps to reproduce:

Install x264 from extra - Repo
Download Big Buck Bunny Blender Movie as MP4
try to encode bb_sunflower_1080p.mp4
play with mplayer or what else to see noise

x264 -o test.264 --input-res 1920x1080 bbb_sunflower_1080p_30fps_normal.mp4

Sorry for reopen this thread....
But again there is image noise.
I tested it on a clean, fresh installed system.
I think, x264 depands on ffmpeg. When i compiled x264 without ffmpeg installed on the system, it produced a x264 which creates noisy video files.
Builds with ffmpeg worked fine.
Sorry for my first report....

Reopening to state that ffmpeg will not be added back to x264 because the circular dependency is way too cumbersome to deal with. You can use the ffmpeg cli to encode using libx264 which is essentially the same as using the x264 binary directly back when we still depended on ffmpeg.
