Bring back MKV support. This would be a huge milestone for OBS users.
I record a bunch of gameplay videos with OBS, which, by default, exports to MKV. The feature was added in 2018, but was removed a year later. I don't want to have to remux my recordings to MP4 every time I record a gameplay video.
Many others are begging for it too. MKV is a container format, and OBS by default exports in H264. Removing support in 2019 was unnecessary and detrimental.
