GET vars specific to this request:
Var | Value | Description |
go | clips | The API section |
do | process_auto_encoding_clip | The API action |
iq | Clip ID | Clip ID |
Resulting Request URL:
The resulting request URL would be similar to this (don't forget to append the required info: key, timestamp, salt and signature):
https://....../api.php?go=clips&do=process_auto_encoding_clip&iq={clip_id}&{required information}
The following POST vars are optional.
Var | Value | Description |
generate_thumbnail | (int) 0 | 1 | Whether to generate the thumbnail/poster images. Ops: 0 (No), 1 (Yes). |
generate_sprite | (int) 0 | 1 | Whether to generate the sprite - video preview. Ops: 0 (No), 1 (Yes) |
encode_media | (int) 0 | 1 | Whether to encode the video files. Ops: 0 (No), 1 (Yes) |
start_processing | (int) 0 | 1 | Whether to start processing the tasks right away. Ops: 0 (No, add tasks to queue only), 1 (Yes) |
activate_when_done | (int) 0 | 1 | Whether to activate the Clip after all tasks are completed. Ops: 0 (No), 1 (Yes) |
delete_source_when_done | (int) 0 | 1 | Whether to delete the encoding source video file after all tasks are completed (and succeeded). Ops: 0 (No), 1 (Yes) |
If the request was successful, you'll receive a response containing:
• ok: If the Clip encoding tasks were added to the queue.
Example:
{ "ok": "The Clip encoding tasks were queued and processing was launched" }
If the request failed (for example, if the Auto-Encoding Clip does not have encoding source video file), you'll receive a response like the following:
{ "error": "CLIP_MEDIA_ERROR", "error_long": "The Clip does not have an associated encoding source" }
