libav is a part of FFmpeg, and the heart of it. But FFmpeg isn't just a skeleton. Most decoders + protocols + demuxers / muxsers + filters + scaler + resampler are native component…

API/ABI is meant to be preserved within a major version, but not across. The deprecation period is typically two years, but deletion is usually much later. Do you have examples to …

For a few years, the default aac coder has been fast. But the twoloop coder is better but slower, and was made default in May 2021. Add `-aac_coder twoloop` (in older builds) and r…

With ffmpeg, use the below command to calculate maximum timestamps ffmpeg -i INPUT -map 0:v -map 0:a -enc_time_base -1 -c copy -f null - Note the time= value at the end of the proc…

Think of ffmpeg as a universal translator. There are 100s of languages in use around the world, with their own syntax, vocabulary, writing system, formal and informal conventions .…

For `-f h264`, `-bsf:v h264_mp4toannexb` is not needed. It will be automatically inserted as needed, with ffmpeg 4.0 or later. For latency, specify a short GOP size, e.g. `-g 50`

A profitable strategy only if it attracts a lot more prey than predators.

The intro of the actual paper* is ambivalent, rather than what the post title asserts. "We critically examine relevant findings and argue that there is no clear evidence for detrim…

It's a shame that Graeme Garden and Barry Cryer appear to have retired.

FFmpeg already has registered channels there. Will update website within a day.

It hasn't, since ffmpeg's inception. It's very unlikely - it would require that ffmpeg verify codec compatibility with the output muxer. Not all muxers have registered a codec tags…

It's not the first tracks. Read http://ffmpeg.org/ffmpeg.html#Stream-selection

The first one will re-encode.

There have been 2000 fixes related to fuzzer issues so far, averaging 400 fixes in recent years. Almost all of them are taken care of by Michael.

I don't see FFmpeg on there. See https://link.springer.com/article/10.1007/s11214-020-00765-9 "The core EDL data processing and compression engine is powered by FFMPEG (ffmpeg.org)…
