Collections of GStreamer usages

Most GStreamer examples found online are either for Linux or for gstreamer 0.10.

This particular release note seems to have covered important changes, such as:

  • ffmpegcolorspace => videoconvert
  • ffmpeg => libav

Applying -v will print out useful information. And most importantly the negotiation results.

ffmpeg -formats

Convert WAV to MP3, mix down to mono (use 1 audio channel), set bit rate to 64 kbps and sample rate to 22050 Hz:

Bret Victor’s Reading List

This is a plain-text version of Bret Victor’s reading list. It was requested by hf on Hacker News.

Highly recommended things!

This is my five-star list. These are my favorite things in all the world.

A few of these works have had an extraordinary effect on my life or way of thinking. They get a sixth star. ★
