Moritz Bunkus🌈<p>MKVToolNix v94 is out, a tiny release with just one feature &amp; one bug fix 😁 <a href="https://www.bunkus.org/2025/07/2025-07-27-mkvtoolnix-v94-0-released/" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">bunkus.org/2025/07/2025-07-27-</span><span class="invisible">mkvtoolnix-v94-0-released/</span></a> Have fun! <a href="https://hachyderm.io/tags/MKVToolNix" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>MKVToolNix</span></a> <a href="https://hachyderm.io/tags/Matroska" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Matroska</span></a></p>
Generic Person<p>Going through some old videos and have decided to use <a href="https://social.linux.pizza/tags/Handbrake" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Handbrake</span></a> to re-encode for space reduction. On this one video, I reduced it from 181.3 MiB to only 38.4 MiB, about a 79% file size reduction! Wow! 🤯</p><p>The original file was an MP4 encoded with H.264 and AAC. I re-encoded the file to <a href="https://social.linux.pizza/tags/Matroska" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Matroska</span></a> using the <a href="https://social.linux.pizza/tags/AV1" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>AV1</span></a> and <a href="https://social.linux.pizza/tags/Opus" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Opus</span></a> codecs. Everything was based on Handbrake's Fast 1080p30 preset.</p><p>(EDIT: To further add, the original audio was at ~256 Kbps encoded in AAC).</p><p>For AV1, the rate factor was set to 30, the frame rate Same as Source, and the rate factor 30. For Opus, I set the bitrate to 64 Kbps.</p>
Tenacity Audio Editor<p>Great news! We now have a working <a href="https://floss.social/tags/Matroska" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Matroska</span></a> exporter on our rebase branch! It hasn't been merged yet, but it will be soon! Hooray! 🎉</p><p>Last up is our dynamic compressor, which will be more challenging since that will need some preliminary work first.</p>
Jason Weatherly<p>Small thing I noticed today: splitting `.mkv` files using `ffmpeg` via the `-ss` and `-t` options works great, but the resulting `.mkv` file contains the wrong number of frames in the metadata. Evidently the total frames from the source file gets written into the metadata instead of the resulting frames post-splitting which is annoying. Not a deal breaker, but kind of annoying...easy to fix with a quick run through `mkvmerge` but still just weird.</p><p><a href="https://social.linux.pizza/tags/matroska" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>matroska</span></a> <a href="https://social.linux.pizza/tags/ffmpeg" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ffmpeg</span></a> <a href="https://social.linux.pizza/tags/splitting" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>splitting</span></a> <a href="https://social.linux.pizza/tags/encoding" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>encoding</span></a></p>
Generic Person<p>Note to self: break a larger task into smaller commits. A good example is porting the <a href="https://social.linux.pizza/tags/Matroska" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Matroska</span></a> exporter to <a href="https://social.linux.pizza/tags/Tenacity" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Tenacity</span></a>'s rebased codebase. I set it aside for a while and I recently came back to it. Throughout this time, I forgot what I was supposed to do.</p><p>Committing smaller bits of the exporter will help my progress in porting this exporter as it reduces the stuff I need to do.</p>
skua<p>2/3</p><p>A little more reading of some non-AI internet had me try just changing the file type suffix from webm to mkv.<br>That's <a href="https://mastodon.social/tags/Matroska" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Matroska</span></a>, <a href="https://mastodon.social/tags/MKV" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>MKV</span></a> - a container.</p><p>And the video (only) plays on the <a href="https://mastodon.social/tags/SamsungTV" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>SamsungTV</span></a> base model code <a href="https://mastodon.social/tags/JU6400" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>JU6400</span></a>.<br>And the TV tells me the audio format ( .opus) is not supported.</p><p>But <a href="https://mastodon.social/tags/FFMPeg" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>FFMPeg</span></a> made short work of transcoding audio. Under 3 minutes instead of hours. Went to aac. Still renaming the webm file to a .mkv container.</p>

Updated the core `sispyhus-matroska` library which adds support for attachment directories. This allows entire directory's worth of files to be added to Matroska files as attachments. To help that out, the MIME-type guessing has gotten a huge upgrade which actually makes this a possibility. Even updated the documentation because...err...it was wrong. #matroska #sisyphus #encoding

RFC 9559: Matroska Media Container Format Specification

#Matroska est un format de conteneur pour du contenu multi-média (son, image, sous-titres, etc). Ce n'est pas un format de données (format utilisé par un codec), mais un moyen de regrouper de manière structurée des données différentes.
