We typically work together with a handful of customers, and, as confidence in the new build grows, we begin recommending it to more and more customers. □įor this reason, we have thus far always chosen to do soft launches for our stack versions. Of course, at the end of that day, we will have those tests in place. Even so, there is always that odd scenario where an odd end-user produces an odd mp4 with an odd second video stream that causes problems for which we didn't have tests yet. Over the years, we have accumulated 9905 automated tests, many of which make use of visual diffs to ensure our encoding is working as expected. We have always had custom builds, which is why we render a dedicated page that features all the supported formats and codecs per stack. So far, we have introduced the following stack versions: The desire to move forward in a way that would not break existing setups led us to engineer a system where new versions of our encoding tools can co-exist, and be completely opt-in. Especially this last category of customers would get understandably upset if their fine-grained instructions were suddenly no longer supported because of an upgrade. Transloadit offers convenient presets, for instance to optimize a video for iPad, that are relatively easily ported, but we also offer fine-grained control over FFmpeg's behavior for power users. At the same time, however, we don't want to break existing setups for customers due to backwards compatibility issues. To stay current, we have to keep upgrading FFmpeg. Technology always moves fast and media encoding forms no exception. In 2011, we sponsored FFmpeg core developer Stefano Sabatini to tailor-make a new version for us because we wanted our customers to enjoy watermarking of webm files, something which wasn't possible at the time. Back then, we only had one version, which we now call v0.0.1. We have used FFmpeg ever since we started back in 2009.
