If you're reading this, FFmpeg developers, please accept my thanks for your work. You have become a "Category Killer"[1] in command-line video tomfoolery. [1] http://www.catb.org/esr/writings/homesteading/cathedral-baza...

Lots of good times with ffserver although thankfully https://github.com/arut/nginx-rtmp-module seems to meet the same use cases and exec ffmpeg under the hood.

Unfortunately is seems that Roman Arutyunyan has not been able (or willing) to keep up the development of nginx-rtmp-module. Thankfully, Mr. Sergey Dryabzhinsky has a fork [0] that has added a lot of nice new features (EXT-X-PROGRAM-DATE-TIME!) and some bug fixes.

Couldn't find a PPA or a docker image for it, would I need to install it from source? I would really like to test AV1 with it.

I’d like to report a bug: V4.0 should be “Si”, not “Wu”

Love ffmpeg! I was trying to do something the other day and couldn’t figure it out, if anyone has any ideas. The end goal is to provide a set of video files, with time stamps for each, splicing them into one file while removing parts I don’t want. That is straightforward enough, as long as you’re willing to re-encode the whole file. Otherwise, it seems like ffmpeg is restricted to make cuts at key frames. It’s rare f…

Depending on the container format, you may not need to re-encode anything. .mp4 supports "edit lists". You can create a .mp4 file that starts at the latest key frame Afraid I don't know how to do what you want with the ffmpeg commandline tool, though, either by partial re-encoding or by edit lists.

Lots of hardware acceleration: - Intel QSV-accelerated MJPEG encoding - NVIDIA NVDEC-accelerated H.264, HEVC, MJPEG, MPEG-1/2/4, VC1, VP8/9 hwaccel decoding - Intel QSV-accelerated overlay filter - OpenCL overlay filter - VAAPI MJPEG and VP8 decoding - AMD AMF H.264 and HEVC encoders - VideoToolbox HEVC encoder and hwaccel - VAAPI-accelerated ProcAmp (color balance), denoise and sharpness filters

Is QSV working on Linux without X server running?

That’s why AV1 is a terrible name, they should come up with something else while it’s still possible changing it.

If you write it lowercase the 1 stands out over the i. av1
