How to download a video from a user's post using API

[Diegolzgz]

I tried this but not working

def download_video_blob(blob_ref, save_path, access_jwt):
"""
Descarga el vídeo utilizando el endpoint /xrpc/com.atproto.sync.getBlob.
Se espera que blob_ref sea el valor del campo '$link' en el objeto video (de tipo blob).
"""
endpoint = f"{BLUESKY_API_BASE_URL}/xrpc/com.atproto.sync.getBlob"
headers = {
'Authorization': f'Bearer {access_jwt}',
'Accept': 'application/octet-stream'
}
params = {"ref": blob_ref}
try:
print(f"Descargando vídeo con blob reference: {blob_ref}")
response = send_request("GET", endpoint, headers=headers, params=params, stream=True)
with open(save_path, "wb") as f:
for chunk in response.iter_content(chunk_size=8192):
f.write(chunk)
print(f"Vídeo descargado exitosamente en: {save_path}")
except Exception as e:
print(f"Error descargando el vídeo blob: {e}")

def process_post(item, access_jwt, csv_writer, headers_auth, image_folder, video_folder, profile_cache, image_counts, video_counts):
[.....]
video_link = "N/A"
embed_obj = record.get("embed", {})
if embed_obj.get("$type", "").startswith("app.bsky.embed.video"):
video_obj = embed_obj.get("video", {})
if video_obj:
blob_ref = video_obj.get("ref", {}).get("$link")
if blob_ref:
video_counts[username] = video_counts.get(username, 0) + 1
video_filename = os.path.join(video_folder, f"{username}_{video_counts[username]}.mp4")
download_video_blob(blob_ref, video_filename, access_jwt)
video_link = blob_ref
else:
print("No se encontró el blob reference del vídeo.")
else:
print("No se encontró el objeto video en el embed.")
else:
uri = base_post.get("uri", "")
last_part = uri.split("/")[-1] if uri else ""
