gstreamer VS MKVToolnix

If you're a fan of the open source multimedia framework GStreamer, you can take advantage of WHIP support as well. Here's a simple pipeline that could be used to publish a webcam and microphone to a stage. This pipeline is specific to MacOS, but can be adapted to any supported OS. Make sure to obtain and set a participant token into IVS_STAGE_TOKEN (or include a raw token instead). - Source: dev.to / 3 months ago

You could also set up a GStreamer pipeline or maybe even use VLC, instead of Motion. Source: 7 months ago

A long time ago when I was looking for a low latency solution for streaming _from_ the Pi (should also have a similar performance in the other direction), gstreamer[1] was the only usable option. [1] https://gstreamer.freedesktop.org/. - Source: Hacker News / about 1 year ago

I get errors when esp32-cam (rtsp://url:8554/mjpep/1) streams via wifi to GStreamer on Nvidia jetson nano (my current use case). Has anyone encountered this problem and how did you resolve this? Source: over 1 year ago

[gstreamer](https://gstreamer.freedesktop.org/) is also very mature media processing and integration solution with [excellent rust support](https://lib.rs/crates/gstreamer). Source: over 1 year ago

Fourth, try remuxing one of the problem files. Use the Multiplexer section of MKVToolNix. This will copy the contents to a new MKV file. It is like putting a letter in a new envelope when the original is damaged, but the pages inside are OK. Source: 5 months ago

If the audio tracks are displayed as unknown, the language flag needs to be set. Use tools such as MKVToolNix Header Editor to configure the language for audio & subtitle tracks. Source: 10 months ago

As for extracting tracks from MKVs, the low-level way would be to use ffmpeg directly (something like ffmpeg -i video.mkv -map 0:s:0 subtitle.sup would extract the first subtitle stream to a .sup file, the extension used for standalone PGS subtitles), but something like MKVToolNix can probably do it as well. That won't help you too much on its own though, since you now just have an external image-based subtitle... Source: 10 months ago

You could use a tool outside of Plex (like MKVToolNix) to combine the video+audio of one version with the audio+subtitles of the other. It gets trickier, or at least more tedious, if the videos aren't exactly the same, since you'd then have to account for any audio/subtitle shifting. Source: 10 months ago

Option 3: Change to MKV container. Use MKVToolNix or similar tools and remux to a MKV container. Note that this may cause problems with Dolby Vision. LG TVs must have Dolby Vision in a MP4 container, otherwise the video will not play correctly. Probably affects other Plex clients as well. Source: 10 months ago
