@nicolaslevy For some reason I'm not able to resolve the DCO issues. Are you able to run the steps to correct the missing DCO sing-offs? |

Description
This is the CMAF-Ham PoC done in the MonteVIDEO Summer camp 2024.
HLS and DASH stand as the predominant video streaming technologies currently. Consequently, users often encounter challenges such as converting between HLS and DASH, manipulating manifests, and programmatically understanding manifest structures.
The Common Media Application Format (CMAF) for segmented media (ISO/IEC 23000-19) addresses these challenges by defining a universal format based on ISOBMFF. Additionally, it introduces the Hypothetical Application Model, a framework illustrating the practical usage of CMAF segments and fragments in streaming applications. This project is inspired by the principles outlined in the CMAF standard and the [Hypothetical Application Model] (Hypothetical Application Model).
In this version it is possible to do a basic conversion between HLS <- HAM -> DASH.
Also a new
sample/folder is added to the project to showcase basic usage of the tools. The cmaf-ham-converter is a basic example of how to use CMAF-Ham to convertHLS <- HAM -> DASHfrom some basic HLS and DASH Manifests.Requirements Checklist
