Video4Linux2: Path to a Standardized Video Codec API - Kamil Debski, Samsung
Hardware video codecs become more and more common and nowadays most SoCs include such a video coding acceleration module. This presentation describes the path from the early stages of development, through numeorus discussions to the final merge of the Multi Format Codec driver in 3.1 kernel. The quikrs of the MFC device and challenges encountered with the hardware encouraged the expansion of the Video4Linux2 API and introduction of the multiplane framework. Typical video coding steps and their implementation in the Video4Linux2 framework will be presented, both from the end user and driver developer perspective.
Kamil Debski has been a Linux enthusiast since 2005. In 2010 he has started his collaboration with the Video4Linux2 community. This collaboration resulted in the expansion of the video codec API. MFC (Multi Format Codec) driver was merged in the mainline kernel in July 2011. It became the first memory-to-memory video codec driver using the Video4Linux2 framework. Thanks to these patches Kamil was included in the list of most active 3.1 kernel developers by the number of changed lines. Kamil... Read More →
