A transcript of a conference (e.g., a video conference, an audio conference, or a telephone call with two or more participants) is processed to extract a conference summary. A graphical user interface is presented that enables a user to edit highlighting to select portions of a conference recording for inclusion in the conference summary. The user can edit highlighting on strings of a transcript and/or on a playback slide bar and the highlighting edits are propagated to both of these interfaces. Video clips selected for inclusion in a summary based on timestamps of strings in a transcript may be extended forward in time to incorporate a nearest I-frame of video. The short video or audio summary may be presented to users along with a text summary of the conference to enable efficient storage and transmission of information from the conference within a unified communications system.

Techniques are presented herein for switching between a software decoder and a hardware decoder in a hybrid decoder. A video bit stream is received. The video bit stream is analyzed to determine whether or not the video bit stream can be decoded by the hardware decoder. When the video bit stream can be decoded by the hardware decoder, the video bit stream is routed to the hardware decoder and also stored in a first buffer. The video bit stream is decoded by the hardware decoder and when a reference frame is decoded, the reference frame is stored in a second buffer. When the video bit stream cannot be decoded by the hardware decoder, the video bit stream is routed to the software decoder for decoding. When an instantaneous decoder refresh (IDR) frame is decoded by the software decoder, the IDR frame is stored in the first buffer.
