Thumbnail generator

This is a small YouTube thumbnail generator, using ffmpeg to overlay image and texts together.

Example

The default request uses these parameters

message ThumbnailRequest {
  repeated string gmsAvatarUrl = 1;
  string title = 2;
  string episodeTitle = 3;
  int32 episodeIndex = 4;
  string backgroundUrl = 5;
  string logoUrl = 6;
}

The following request

{
  gmsAvatarUrl: [
    "https://upload.wikimedia.org/wikipedia/commons/9/9a/Gull_portrait_ca_usa.jpg",
  ],
  title: "Squawk",
  episodeTitle: "Squaaaaawwwk",
  episodeIndex: 1,
  backgroundUrl: "https://upload.wikimedia.org/wikipedia/commons/9/9a/Gull_portrait_ca_usa.jpg",
  logoUrl: "https://upload.wikimedia.org/wikipedia/commons/9/9a/Gull_portrait_ca_usa.jpg",
}
