Really sounds like they confused it with AVI (or maybe ASF/WMV? – could really
be either from the description). Regardless…

They may have a point for that though: While MKV is popular with video
*editing*, for *publishing* the expected container format seems to generally be
MP4 for MPEG LA A/V codecs (H.264/H.265 with MP3/AAC) and WebM for Xiph A/V
codecs (VP8/VP9/AV1 with Vorbis/Opus).

Based on this, I’ll propose an alternate issue description that is neither both
inaccurate nor slightly offensive:


# Kamoso only supports recording video using the MKV container format

Currently Kamoso only allows videos to be recorded only using the MKV container
format. This format, while OK for video editing and archival, is not generally
accepted on video publishing sites and hence makes Kamoso harder to use when
recording video for publishing. As such, it would be nice if Kamoso allowed
recording video using an MP4 container format containing either H.264 or H.265
video and MP3 or AAC audio, as that is still the most accepted format for video
publishing currently. Since these formats are proprietary and a commonly
accepted Open Source format stack exists it would be preferable if, at the same
time, the option to also record video using the WebM container format
containing either VP8 or VP9 video and Vorbis or Opus audio also be added.

Most likely support for any of these would “just” boil down to passing the
right set of parameters to GStreamer, so it shouldn’t make much difference how
many format options are exposed in the UI – within reason of course. Some
feedback from GStreamer might be needed for the UI however since not all
installations include support for encoding to proprietary formats. I’d assume
the following options (drop-down menu) would be ideal:

  * The current MKV video configuration – needs a good description
  * MP4 (proprietary, modest compression, highly compatible, H.264/MP3)
  * MP4 (proprietary, high compression, usually compatible, H.265/AAC)
  * WebM (open, modest compression, often compatible, VP8/Vorbis)
  * WebM (open, high compression, usually compatible, VP9/Opus)
