%avi encoder seems to be broken

[Rafi594]

Hello,

I'm currently trying to use output.external for using custom ffmpeg command but the output have a blinking green screen (probably pixel format issues)

I have also tried with output.file(%avi, fallible=true, "video.flv", stream) and I get the same issue.

I made a workaround by replacing %avi by %ffmpeg(format="avi",%video(codec="rawvideo", pixel_format="yuv420p"),%audio(codec="pcm_s16le"))

Script for reproducing

audio = input.http("http://127.0.0.1:8000/audio.aac")

video = video.testsrc.ffmpeg(pattern="testsrc2")

stream = mux_video(video=video, audio)

output.external(
  self_sync=true,
  fallible=true,
  %avi,
  "ffmpeg -re -i pipe:0 -f avi -c:v h264_nvenc -b:v 5000k -c:a aac -b:a 128k -pix_fmt yuv420p -f flv rtmp://127.0.0.1:1935/test-stream",
  stream)

Video.mp4

Thanks for reporting, glad you found a workaround.
