libva VS ffmpeg-libav-tutorial

Intel's docs seem outdated (version 2.13). Version 2.14: Add av1 encode interfaces

Stating that libva (https://github.com/intel/libva) version 2.10.0 is already installed on my machine. I think I didnt install it, seems like debian ships with it preinstalled?

Hey, un-wanted fun fact? Intel actually develops the VA-API specification.

To understand the Linux video stack see slides #114 and #178 from https://bootlin.com/doc/training/graphics/graphics-slides.pdf and https://01.org/linuxmedia and https://gstreamer.freedesktop.org/documentation/application-development/introduction/gstreamer.html?gi-language=c

Which appears to be VAProfileJPEGBaseline? ( https://github.com/intel/libva/blob/master/va/va.h#L486 )

Xwayland requires DRI3, libva supports only DRI2. Under native X11 it is not a problem, under Xwayland it is: https://github.com/intel/libva/issues/122

The FFmpeg libraries are possibly the worst thing I have ever worked with in my life. I have never been more afraid to use a library than this one. This tutorial is very outdated, eg. `AVPicture`, which is used throughout, is completely deprecated and removed from the library, so you will simply encounter linker errors trying to follow this tutorial.

FFmpeg libraries randomly break themselves, so if you find an answer from a few years ago, chances are it's useless. Want to free an AVPacket? `av_free_packet` is deprecated,. You can use `av_packet_unref` (but there's _also_ a function named `av_packet_free` that doesn't do quite the same thing).

Most questions on Stack Overflow or related platforms have no replies, the library has literally zero documentation, it has very little error handling, which means if you're a bad C developer like me you are required to recompile FFmpeg with debugging information unstripped so you can trace segfaults in gdb.

https://github.com/leandromoreira/ffmpeg-libav-tutorial/ is a better and more up-to-date tutorial than this one.

I found this . I think you need an older version of ffmpeg to use the program, try to write it under the AUR to see if the mantainer is still active and knows the problem.

I think you're supposed to read the header files? I have no idea how people write ffmpeg stuff. The only good tutorial I've seen is: https://github.com/leandromoreira/ffmpeg-libav-tutorial

Much of it I learned from An ffmpeg and SDL Tutorial (outdated, but the core idea persists), and from ffmpeg-libav-tutorial.

If you are not familiar with libav, ffmpeg-libav-tutorial is a great introduction.

Btw, if you want to encode anything higher than 1080p60 using the Videocore VI, you'll need to use an external library like ffmpeg. There is a good tutorial for ffmpeg too - https://github.com/leandromoreira/ffmpeg-libav-tutorial . This should teach you how to encode the raw video stream you get from the camera into a codec of your choice.
