Nesta página, explicamos como inserir sobreposições em vídeos transcodificados. Uma sobreposição
consiste em uma imagem JPEG que é inserida na parte superior do vídeo de saída e pode
ser esmaecida ou desativada durante um período de tempo especificado. Para inserir uma
sobreposição, use a matriz
overlays no
modelo JobConfig.
Fazer upload de uma imagem para o Cloud Storage
Para começar, faça o seguinte para fazer o upload de uma imagem de sobreposição para o
bucket do Cloud Storage:
Selecione um arquivo JPEG para fazer o upload da sua máquina local.
Criar uma sobreposição
Você pode criar dois tipos de sobreposição: estática ou
animada. Os dois tipos de sobreposição usam uma imagem estática.
É possível mostrar ou ocultar sobreposições estáticas. As sobreposições animadas são compatíveis
com a esmaecimento e esmaecem animações da imagem.
É possível inserir várias sobreposições em um único vídeo de saída.
Criar uma sobreposição estática
No objeto image, use o campo
uri para
especificar a imagem de sobreposição no Cloud Storage. No objeto resolution, defina
os valores x e y de 0 a 1,0. O valor 0 mantém a resolução da imagem de origem
para a dimensão; Um valor de 1.0 expandirá a imagem para corresponder
à dimensão do vídeo de saída. Por exemplo, use os valores x: 1 e y:
0.5 para esticar a imagem de sobreposição como largura total e metade da altura do
vídeo de saída.
Na matriz animations, crie um objeto animationStatic com as coordenadas x e y
de 0 a 1,0. Essas coordenadas são baseadas na resolução do
vídeo de saída. Use os valores x: 0 e y: 0 para posicionar o canto superior esquerdo
da sobreposição no canto superior esquerdo do vídeo de saída. Especifique quando a sobreposição
deve aparecer na linha do tempo de saída do vídeo usando o campo startTimeOffset.
Para remover a animação estática, crie um objeto animationEnd. Especifique quando
a animação deve terminar (ou seja, a sobreposição desaparece) na linha do tempo
da saída do vídeo usando o campo startTimeOffset.
LOCATION: o local onde seu job será executado. Use
uma das regiões compatíveis:
us-central1
us-west1
us-west2
us-east1
us-east4
southamerica-east1
asia-east1
asia-south1
asia-southeast1
europe-west1
europe-west2
europe-west4
GCS_BUCKET_NAME: o nome do bucket do
Cloud Storage criado.
GCS_INPUT_VIDEO: o nome do vídeo no
bucket do Cloud Storage que você está transcodificando, como my-vid.mp4.
Este campo precisa considerar todas as pastas criadas no bucket (por exemplo, input/my-vid.mp4).
GCS_INPUT_OVERLAY: o nome da imagem
JPEG no bucket do Cloud Storage que você está usando para a sobreposição, como
my-overlay.jpg. Este campo precisa considerar todas as pastas criadas no bucket (por exemplo, input/my-overlay.jpg).
GCS_OUTPUT_FOLDER: nome da pasta do
Cloud Storage em que você quer salvar as saídas de vídeo codificadas.

No objeto image, use o campo
uri para
especificar a imagem de sobreposição no Cloud Storage. No objeto resolution, defina
os valores x e y de 0 a 1,0. O valor 0 mantém a resolução da imagem de origem
para a dimensão; Um valor de 1.0 expandirá a imagem para corresponder
à dimensão do vídeo de saída. Por exemplo, use os valores x: 0 e y: 0
para manter a resolução original da imagem de sobreposição.
Na matriz animations, crie um objeto animationFade com um fadeType de
FADE_IN. Defina as coordenadas x e y de 0 a 1.0. Essas coordenadas são
baseadas na resolução do vídeo de saída. Use os valores x: 0.5 e y: 0.5 para
posicionar o canto superior esquerdo da sobreposição no centro do vídeo de saída.
Especifique quando a sobreposição deve começar a aparecer na linha do tempo de saída do vídeo
usando o campo startTimeOffset. A sobreposição precisa estar totalmente visível pelo
tempo definido no campo endTimeOffset.
Para esmaecer a sobreposição, crie outro objeto animationFade. Desta vez, defina
fadeType como FADE_OUT. Insira as coordenadas de posição e os horários de início
e término como antes.

Alfa da sobreposição começa em 0 e termina em 1.0. O canto superior esquerdo
da sobreposição aparece no centro do vídeo de saída. A sobreposição aparece
na resolução original da imagem de sobreposição.
