IRT uses GPAC MP4Box to generate a wide set of streams
IRT is the primary research institute for public-broadcasting organisations in Germany, Austria and Switzerland.
The IRT teams have used GPAC and other open-source tools such as x264, FFmpeg, x265, dash.js, video.js to generate an extensive repository of differently encoded Audio- and Videostreams for PC, Smartphones, Tablets and HbbTV-Devices.
The streams target:
- Computers (desktop and laptops)
- Smartphones and tablets
- HbbTV-Devices
The generated adaptive streaming formats are:
- MPEG-DASH
- Apple HLS
- Adobe HDS
Codecs include:
- Video: H.264, H.265
- Audio:HE/AAC, E/AC3
Containers are:
- MPEG-TS
- MP4
Resolutions range from:
- SDTV to UHD
- progressive or interlaced
- high framereate (>= 50Hz)
We encourage this kind of initiative. Interoperability can only be achieved with test content and appropriate tools. In 2013 we wrote an article about HbbTV, test streams and conformance tools.
Find the dataset on the IRT website with a short presentation.
Our partners from Bitmovin also published a list of free datasets. No doubt this one deserves to be listed there too!
