Hi
In recent months, a new version of mplayer 1.5 has been released, building on the work of previous releases of this program under AOS4.
New things have been added and some things have been improved. From the beginning, the idea was that mplayer could also use the va-api video output.
For a few months now, we have been testing a solution based on the mplayer port under Linux, where there is a vaapi video output.
To make it work, we need to undo some changes in the ffmpeg code and add the code to mplayer. Changes to ffmpeg and mplayer alone will not make it work. It was also necessary to adapt the va-api implementation to work with the existing va-api version under AOS4.
Lastly, mplayer and ffmpeg itself appears to work under AOS4. The only problem is the video output. The video output in mplayer itself is on X11.
For testing, a simple output was made to simulate operation under AOS4. What is missing is for this output to be rewritten/re-written in order to lastdznie confirm the operation.
Here is my request, is there any person who could help with this ?
