If the type is found autoplugging starts. ++ * ++ * decodebin2 internally organizes the elements it autoplugged into GstDecodeChains ++ * and GstDecodeGroups. A decode chain is a single chain of decoding, this ++ * means that if decodebin2 every autoplugs an element with two+ srcpads ++ * (e.g. a demuxer) this will end the chain and everything following this ++ * demuxer will be put into decode groups below the chain. Otherwise, ++ * if an element has a single srcpad that outputs raw data the decode chain ++ * is ended too and a GstDecodePad is stored and blocked. ++ * ++ * A decode group combines a number of chains that are created by a ++ * demuxer element. All those chains are connected through a multiqueue to ++ * the demuxer. A new group for the same demuxer is only created if the ++ * demuxer has signaled no-more pads, in which case all following pads ++ * create a new chain in the new group. ++ * ++ * This continues until the top-level decode chain is complete. A decode ++ * chain is complete if it either ends with a blocked endpad, if autoplugging ++ * stopped because no suitable plugins could be found or if the active group ++ * is complete. A decode group OTOH is complete if all child chains are complete. ++ * ++ * If this happens at some point, all endpads of all active groups are exposed. ++ * For this decodebin2 adds the endpads, signals no-more-pads and then unblocks ++ * them. Now playback starts. ++ * ++ * If one of the chains that end on a endpad receives EOS decodebin2 checks upwards ++ * via the parent pointers if all chains and groups are drained. In that case ++ * everything goes into EOS. ++ * If there is a chain where the active group is drained but there exist next groups ++ * the active group is hidden (endpads are removed) and the next group is exposed. ++ * ++ * Note 1: If we're talking about blocked endpads this really means that the ++ * *target* pads of the endpads are blocked. Pads that are exposed to the outside ++ * should never ever be blocked! ++ * ++ * Note 2: If a group is complete and the parent's chain demuxer adds new pads ++ * but never signaled no-more-pads this additional pads will be ignored!
