# ストリーミングと再生
|
||||
|
||||
VideoDBはオンデマンドでストリーミングを生成し、任意の標準ビデオプレーヤーで即時再生できるHLS互換のURLを返す。レンダリング時間やエクスポート待ちは不要——編集、検索、合成されたコンテンツは即座にストリーミングできる。
|
||||
|
||||
## 前提条件
|
||||
|
||||
ビデオはストリーミングを生成するために**コレクションにアップロードされている必要がある**。検索ベースのストリーミングには、ビデオも**インデックス化されている必要がある**(音声単語および/またはシーン)。インデックス作成の詳細については [search.md](search.md) を参照。
|
||||
|
||||
## コアコンセプト
|
||||
|
||||
### ストリーミング生成
|
||||
|
||||
VideoDBのすべてのビデオ、検索結果、タイムラインは**ストリームURL**を生成できる。このURLはオンデマンドでコンパイルされるHLS(HTTPライブストリーミング)マニフェストを指す。
|
||||
|
||||
```python
|
||||
# From a video
|
||||
stream_url = video.generate_stream()
|
||||
|
||||
# From a timeline
|
||||
stream_url = timeline.generate_stream()
|
||||
|
||||
# From search results
|
||||
stream_url = results.compile()
|
||||
```
|
||||
|
||||
## 単一ビデオのストリーミング
|
||||
|
||||
### 基本再生
|
||||
|
||||
```python
|
||||
import videodb
|
||||
|
||||
conn = videodb.connect()
|
||||
coll = conn.get_collection()
|
||||
video = coll.get_video("your-video-id")
|
||||
|
||||
# Generate stream URL
|
||||
stream_url = video.generate_stream()
|
||||
print(f"Stream: {stream_url}")
|
||||
|
||||
# Open in default browser
|
||||
video.play()
|
||||
```
|
||||
|
||||
### 字幕付き
|
||||
|
||||
```python
|
||||
# Index and add subtitles first
|
||||
video.index_spoken_words(force=True)
|
||||
stream_url = video.add_subtitle()
|
||||
|
||||
# Returned URL already includes subtitles
|
||||
print(f"Subtitled stream: {stream_url}")
|
||||
```
|
||||
|
||||
### 特定のセグメント
|
||||
|
||||
タイムスタンプ範囲のタイムラインを渡すことでビデオの一部のみをストリーミングする:
|
||||
|
||||
```python
|
||||
# Stream seconds 10-30 and 60-90
|
||||
stream_url = video.generate_stream(timeline=[(10, 30), (60, 90)])
|
||||
print(f"Segment stream: {stream_url}")
|
||||
```
|
||||
|
||||
## タイムラインコンポジションのストリーミング
|
||||
|
||||
マルチアセットコンポジションを構築してリアルタイムでストリーミングする:
|
||||
|
||||
```python
|
||||
import videodb
|
||||
from videodb.timeline import Timeline
|
||||
from videodb.asset import VideoAsset, AudioAsset, ImageAsset, TextAsset, TextStyle
|
||||
|
||||
conn = videodb.connect()
|
||||
coll = conn.get_collection()
|
||||
|
||||
video = coll.get_video(video_id)
|
||||
music = coll.get_audio(music_id)
|
||||
|
||||
timeline = Timeline(conn)
|
||||
|
||||
# Main video content
|
||||
timeline.add_inline(VideoAsset(asset_id=video.id))
|
||||
|
||||
# Background music overlay (starts at second 0)
|
||||
timeline.add_overlay(0, AudioAsset(asset_id=music.id))
|
||||
|
||||
# Text overlay at the beginning
|
||||
timeline.add_overlay(0, TextAsset(
|
||||
text="Live Demo",
|
||||
duration=3,
|
||||
style=TextStyle(fontsize=48, fontcolor="white", boxcolor="#000000"),
|
||||
))
|
||||
|
||||
# Generate the composed stream
|
||||
stream_url = timeline.generate_stream()
|
||||
print(f"Composed stream: {stream_url}")
|
||||
```
|
||||
|
||||
**重要な注意事項:** `add_inline()` は `VideoAsset` のみを受け入れる。`AudioAsset`、`ImageAsset`、`TextAsset` には `add_overlay()` を使用する。
|
||||
|
||||
詳細なタイムライン編集については [editor.md](editor.md) を参照。
|
||||
|
||||
## 検索結果のストリーミング
|
||||
|
||||
すべての一致するクリップを含む単一のストリームに検索結果をコンパイルする:
|
||||
|
||||
```python
|
||||
from videodb import SearchType
|
||||
from videodb.exceptions import InvalidRequestError
|
||||
|
||||
video.index_spoken_words(force=True)
|
||||
try:
|
||||
results = video.search("key announcement", search_type=SearchType.semantic)
|
||||
|
||||
# Compile all matching shots into one stream
|
||||
stream_url = results.compile()
|
||||
print(f"Search results stream: {stream_url}")
|
||||
|
||||
# Or play directly
|
||||
results.play()
|
||||
except InvalidRequestError as exc:
|
||||
if "No results found" in str(exc):
|
||||
print("No matching announcement segments were found.")
|
||||
else:
|
||||
raise
|
||||
```
|
||||
|
||||
### 個別の検索結果をストリーミングする
|
||||
|
||||
```python
|
||||
from videodb.exceptions import InvalidRequestError
|
||||
|
||||
try:
|
||||
results = video.search("product demo", search_type=SearchType.semantic)
|
||||
for i, shot in enumerate(results.get_shots()):
|
||||
stream_url = shot.generate_stream()
|
||||
print(f"Hit {i+1} [{shot.start:.1f}s-{shot.end:.1f}s]: {stream_url}")
|
||||
except InvalidRequestError as exc:
|
||||
if "No results found" in str(exc):
|
||||
print("No product demo segments matched the query.")
|
||||
else:
|
||||
raise
|
||||
```
|
||||
|
||||
## オーディオ再生
|
||||
|
||||
オーディオコンテンツの署名付き再生URLを取得する:
|
||||
|
||||
```python
|
||||
audio = coll.get_audio(audio_id)
|
||||
playback_url = audio.generate_url()
|
||||
print(f"Audio URL: {playback_url}")
|
||||
```
|
||||
|
||||
## 完全なワークフロー例
|
||||
|
||||
### 検索からストリーミングへのパイプライン
|
||||
|
||||
単一のワークフローで検索、タイムラインコンポジション、ストリーミングを組み合わせる:
|
||||
|
||||
```python
|
||||
import videodb
|
||||
from videodb import SearchType
|
||||
from videodb.exceptions import InvalidRequestError
|
||||
from videodb.timeline import Timeline
|
||||
from videodb.asset import VideoAsset, TextAsset, TextStyle
|
||||
|
||||
conn = videodb.connect()
|
||||
coll = conn.get_collection()
|
||||
video = coll.get_video("your-video-id")
|
||||
|
||||
video.index_spoken_words(force=True)
|
||||
|
||||
# Search for key moments
|
||||
queries = ["introduction", "main demo", "Q&A"]
|
||||
timeline = Timeline(conn)
|
||||
timeline_offset = 0.0
|
||||
|
||||
for query in queries:
|
||||
try:
|
||||
results = video.search(query, search_type=SearchType.semantic)
|
||||
shots = results.get_shots()
|
||||
except InvalidRequestError as exc:
|
||||
if "No results found" in str(exc):
|
||||
shots = []
|
||||
else:
|
||||
raise
|
||||
|
||||
if not shots:
|
||||
continue
|
||||
|
||||
# Add the section label where this batch starts in the compiled timeline
|
||||
timeline.add_overlay(timeline_offset, TextAsset(
|
||||
text=query.title(),
|
||||
duration=2,
|
||||
style=TextStyle(fontsize=36, fontcolor="white", boxcolor="#222222"),
|
||||
))
|
||||
|
||||
for shot in shots:
|
||||
timeline.add_inline(
|
||||
VideoAsset(asset_id=shot.video_id, start=shot.start, end=shot.end)
|
||||
)
|
||||
timeline_offset += shot.end - shot.start
|
||||
|
||||
stream_url = timeline.generate_stream()
|
||||
print(f"Dynamic compilation: {stream_url}")
|
||||
```
|
||||
|
||||
### マルチビデオストリーム
|
||||
|
||||
異なるビデオからのクリップを単一のストリームに組み合わせる:
|
||||
|
||||
```python
|
||||
import videodb
|
||||
from videodb.timeline import Timeline
|
||||
from videodb.asset import VideoAsset
|
||||
|
||||
conn = videodb.connect()
|
||||
coll = conn.get_collection()
|
||||
|
||||
video_clips = [
|
||||
{"id": "vid_001", "start": 0, "end": 15},
|
||||
{"id": "vid_002", "start": 10, "end": 30},
|
||||
{"id": "vid_003", "start": 5, "end": 25},
|
||||
]
|
||||
|
||||
timeline = Timeline(conn)
|
||||
for clip in video_clips:
|
||||
timeline.add_inline(
|
||||
VideoAsset(asset_id=clip["id"], start=clip["start"], end=clip["end"])
|
||||
)
|
||||
|
||||
stream_url = timeline.generate_stream()
|
||||
print(f"Multi-video stream: {stream_url}")
|
||||
```
|
||||
|
||||
### 条件付きストリーミングアセンブリ
|
||||
|
||||
検索結果の可用性に基づいてストリームを動的に構築する:
|
||||
|
||||
```python
|
||||
import videodb
|
||||
from videodb import SearchType
|
||||
from videodb.exceptions import InvalidRequestError
|
||||
from videodb.timeline import Timeline
|
||||
from videodb.asset import VideoAsset, TextAsset, TextStyle
|
||||
|
||||
conn = videodb.connect()
|
||||
coll = conn.get_collection()
|
||||
video = coll.get_video("your-video-id")
|
||||
|
||||
video.index_spoken_words(force=True)
|
||||
|
||||
timeline = Timeline(conn)
|
||||
|
||||
# Try to find specific content; fall back to full video
|
||||
topics = ["opening remarks", "technical deep dive", "closing"]
|
||||
|
||||
found_any = False
|
||||
timeline_offset = 0.0
|
||||
for topic in topics:
|
||||
try:
|
||||
results = video.search(topic, search_type=SearchType.semantic)
|
||||
shots = results.get_shots()
|
||||
except InvalidRequestError as exc:
|
||||
if "No results found" in str(exc):
|
||||
shots = []
|
||||
else:
|
||||
raise
|
||||
|
||||
if shots:
|
||||
found_any = True
|
||||
timeline.add_overlay(timeline_offset, TextAsset(
|
||||
text=topic.title(),
|
||||
duration=2,
|
||||
style=TextStyle(fontsize=32, fontcolor="white", boxcolor="#1a1a2e"),
|
||||
))
|
||||
for shot in shots:
|
||||
timeline.add_inline(
|
||||
VideoAsset(asset_id=shot.video_id, start=shot.start, end=shot.end)
|
||||
)
|
||||
timeline_offset += shot.end - shot.start
|
||||
|
||||
if found_any:
|
||||
stream_url = timeline.generate_stream()
|
||||
print(f"Curated stream: {stream_url}")
|
||||
else:
|
||||
# Fall back to full video stream
|
||||
stream_url = video.generate_stream()
|
||||
print(f"Full video stream: {stream_url}")
|
||||
```
|
||||
|
||||
### ライブイベントのリキャップ
|
||||
|
||||
イベント録音を複数のセクションを持つストリーミング可能なリキャップに処理する:
|
||||
|
||||
```python
|
||||
import videodb
|
||||
from videodb import SearchType
|
||||
from videodb.exceptions import InvalidRequestError
|

```
|
||||
|
||||
***
|
||||
|
||||
## ヒント
|
||||
|
||||
* **HLS互換性**:ストリームURLはHLSマニフェスト(`.m3u8`)を返す。Safariでネイティブに動作し、他のブラウザではhls.jsや類似のライブラリで動作する。
|
||||
* **オンデマンドコンパイル**:ストリーミングはリクエスト時にサーバーサイドでコンパイルされる。初回再生には短いコンパイル遅延が発生する場合がある;同じコンポジションの後続再生はキャッシュされる。
|
||||
* **キャッシング**:`video.generate_stream()`(引数なし)の2回目の呼び出しは再コンパイルせずにキャッシュされたストリームURLを返す。
|
||||
* **セグメントストリーム**:`video.generate_stream(timeline=[(start, end)])` は完全な `Timeline` オブジェクトを構築せずに特定のクリップをストリーミングする最速の方法。
|
||||
* **インラインとオーバーレイ**:`add_inline()` は `VideoAsset` のみを受け入れ、アセットをメイントラックに順番に配置する。`add_overlay()` は `AudioAsset`、`ImageAsset`、`TextAsset` を受け入れ、指定された開始時間にそれらを上にオーバーレイする。
|
||||
* **TextStyleのデフォルト**:`TextStyle` のデフォルトは `font='Sans'`、`fontcolor='black'`。テキストの背景色には `boxcolor`(`bgcolor` ではない)を使用する。
|
||||
* **生成との組み合わせ**:`coll.generate_music(prompt, duration)` と `coll.generate_image(prompt, aspect_ratio)` を使用してタイムラインコンポジションのアセットを作成する。
|
||||
* **再生**:`.play()` はデフォルトのシステムブラウザでストリームURLを開く。プログラム的な使用には直接URLの文字列を処理する。
