Adopting a multi-codec streaming approach, as suggested in the paper, can introduce several challenges and trade-offs. One of the main challenges is the complexity of managing and maintaining multiple codecs simultaneously. Platform operators would need to ensure seamless integration of different codecs into their transcoding workflows, which may require additional resources and expertise. Furthermore, the need to encode and store multiple versions of the same content in different codecs can increase storage costs and operational complexity.
Another challenge is ensuring consistent quality across different codec versions. Variations in encoding parameters and algorithms between codecs can lead to differences in video quality, requiring careful monitoring and quality control measures to maintain a consistent viewing experience for users.
Trade-offs in adopting a multi-codec streaming approach include the potential increase in computational resources and encoding time needed to process and deliver content in multiple codecs. This can impact overall transcoding efficiency and scalability, especially for platforms with high volumes of video content. Additionally, the cost implications of licensing multiple codecs and the overhead of managing diverse encoding workflows should be considered when implementing a multi-codec streaming strategy.
