Massive &quot;thank you&quot; to FFmpeg for being an amazing tool.<p>My app pivotally depends on FFmpeg extracting screenshots of videos for users to browse through: <a href="https:&#x2F;&#x2F;github.com&#x2F;whyboris&#x2F;Video-Hub-App" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;whyboris&#x2F;Video-Hub-App</a>

What exactly is the &quot;GIF parser&quot;? I thought FFmpeg already did GIF I&#x2F;O.

remember the dark ages when we had to actually care about codecs and which ones were installed at any given point in time?

Does this play nice with Python youtube-dl? [1] [2]. I want to run a python script on my computer that captures youtube audio of certain government meetings without first having to dl the entire video and convert it (while doing a bunch of other stuff before and after automatically, all without me touching anything).<p>[1] <a href="https:&#x2F;&#x2F;stackoverflow.com&#x2F;questions&#x2F;27473526&#x2F;download-only-audio-from-youtube-video-using-youtube-dl-in-python-script" rel="nofollow">https:&#x2F;&#x2F;stackoverflow.com&#x2F;questions&#x2F;27473526&#x2F;download-only-a...</a><p>[2] <a href="https:&#x2F;&#x2F;stackoverflow.com&#x2F;questions&#x2F;39665160&#x2F;youtube-dl-python-script-postprocessing-error-ffmpeg-codecs-arent-being-recogn" rel="nofollow">https:&#x2F;&#x2F;stackoverflow.com&#x2F;questions&#x2F;39665160&#x2F;youtube-dl-pyth...</a>

Can&#x27;t say I blame them for the removal of libndi-newtek, given the situation, but I wish FFMpeg (and gstreamer) had ndi support.<p>Would love to see an open source NDI, but I know newtek will never allow it.

Is there anything in the new release that would allow an encoder to be &quot;motion-aware&quot;?<p>e.g. if the video is static, don&#x27;t store any information. But if there is movement in the video, start storing frames etc<p>WHY? I find myself recording lots of videos of me talking through code in an IDE. The screen mostly static, with some occasional the screen scrolling. The regular tradeoff-space afforded by CRF doesn&#x27;t seem to get me the size results I believe are possible.

Is there any higher level libraries for JS that wrap FFmpeg commands cleaner?<p>I&#x27;m building some software on using it is kind of cumbersome

A little confused on what they mean by PCM-DVD encoder. Wasn&#x27;t ffmpeg always able to do this?

Nice to see improved HEVC 4:4:4 support in Linux.
