Video Engineer should have experience in Working on streaming delivery types (HLS, MPEG-DASH)
(HLS) is standouts amongst the most developed guidelines accessible today, ruling the versatile bitrate is streaming market and giving affordability if you need to attempt and cover all the vast number of various devices available. HLS has turned into the primary strategy for streaming sound and video over HTTP from a standard HTTP-based web server and gives backing to both live broadcasts and also prerecorded (VOD) Video on Demand content.
For 2015 adaptive bitrate streaming norms, HLS is the reasonable pioneer with around 75% of the piece of the overall industry, with different measures, for example, Microsoft Smooth Streaming, Dash and HDS taking the other 25%.
For real “live” content, for example, an occasion, a streaming server, (for example, Wowza) is regularly expected to ingest the live nourish and yield the HLS stream. however, for any VOD which is a pre-recorded content, no streaming server is required.
MPEG DASH (Dynamic Adaptive Streaming over HTTP) is a creating ISO Standard (ISO/IEC 23009-1) that ought to be settled by mid-2012. As the name recommends, DASH is a standard for versatile Streaming over HTTP that can supplant existing exclusive advancements like Microsoft Smooth Streaming, Adobe Dynamic Streaming, and Apple HTTP Live Streaming (HLS). A bound together standard would be an aid to substance distributors, who could deliver one arrangement of records that play on all DASH-good gadgets.

The DASH working gathering has industry support from a scope of organisations, with patrons including primary partners like Apple, Adobe, Microsoft, Netflix, Qualcomm, and numerous others. In any case, while Microsoft has shown that it will probably bolster the standard when it’s finished, Adobe and Apple have not given the same direction, and until these two noteworthy players uphold DASH, it will increase little footing in the business sector.
A more major issue is that MPEG-DASH doesn’t resolve the HTML5 codec issue. That is, DASH is codec rationalise, which implies that it can actualise in either H.264 or WebM. Since all HTML5 programs all around uphold neither codec, this may mean that DASH client will need to make various streams utilising numerous codecs, lifting encoding, stockpiling, and regulatory expenses.
