MPEG-HEVC Support in GPAC

Posted on 26 April 2013 by cconcolato

This week was held in Incheon, South Korea, the 104th MPEG meeting. For this occasion, the GPAC team worked hard to prepare the following contribution.

J. Le Feuvre and C. Concolato, GPAC Updates on ISOBMFF, MPEG, Incheon, South Korea, April 2013, n° M29230 [PDF].

This contribution discusses SVC, WebVTT and in particular the support for MPEG-HEVC (High Efficiency Video Coding, a.k.a. H.265) packaging, streaming and playback in GPAC. I’ve extracted the HEVC related part of this contribution in this post. Continue reading →

Live DASH audio/video encoder: DashCast

Posted on 23 April 2013 by cconcolato

Dear GPAC users,

We’ve just released a new application which might be of interest to some (hopefully many) of you. It’s called DashCast. It’s an application which allows you to:

  1. transcode a live/non-live stream in multiple qualities (eg. bitrate and resolution).
  2. segment a continuous stream in small chunks and packetize them for delivery via Dynamic Adaptive Streaming over HTTP (DASH) standard.

For more information, check out the dedicated page.

Deferred rendering in GPAC

To enable this mode, you need to modify the GPAC configuration file (i.e. GPAC.cfg or .gpacrc), by setting the DrawMode to “defer-debug” in the Compositor section. Continue reading →

Posted on 23 August 2012 by bouqueau

We heard today about some MPEG-DASH experiments in Google Chrome. We think Google is behind this initiative because 1) there is a Youtube logo, 2) the data are stored on Google Cloud Storage and 3) it used the Media Source API which is developped by Google for a future use with HTML5 <video> (more on that below).
