Streamgrab

What it saves

When a video file, an HLS playlist (.m3u8) or a DASH manifest (.mpd) loads on the page, the toolbar icon gets a number. Open the popup, pick a quality and press Download.

What it saves, and what it does not

• Direct video files (MP4 and WebM): saved as they are.
• HLS streams: the segments are fetched, decrypted when the stream uses plain AES-128 with its own key, and joined into one MP4 on your computer. MPEG-TS pieces are converted to MP4. If a stream cannot be converted, it is saved as a .ts file and the Downloads page says so.
• Audio only (Pro): the sound of an HLS or DASH stream as an .m4a file. Audio that is not AAC is saved as it is, in its own container, and the Downloads page says so.
• Live HLS streams (Pro): Record follows the playlist and ends when you press Stop, the stream ends, or the server stops answering. A recording is saved as numbered MP4 parts every 30 minutes, or as one file if Options say so; a part that cannot be converted is saved as a .ts file.
• DASH streams: one video track and one audio track are fetched and saved as one MP4 file. WebM streams still come as separate video and audio files, and the Downloads page says so.

It does not save: YouTube (Streamgrab refuses youtube.com and the servers that deliver its video); anything protected by DRM, meaning HLS with SAMPLE-AES or Widevine, PlayReady or FairPlay keys, and DASH manifests with ContentProtection; and live DASH streams. A live HLS stream can be recorded on Pro, until you press Stop or the stream ends. A server that checks where each request comes from may refuse the download.
