@ -191,6 +191,10 @@ In addition to all the fields present in the buffering message, the BUFFERING
query contains the following field, which indicate the available downloaded
range in a specific format and the estimated time to complete:
"busy", G_TYPE_BOOLEAN
- if buffering was busy. This flag allows the application to pause the
pipeline by using the query only.
"format", GST_TYPE_FORMAT
- the format of the "start" and "stop" values below
