Comment (by msiders):
Hi oromit,
Thank you for pointing to the initialization code of the ffmpeg.c
Now I see that only one "ist->hwaccel_id" is used.
I feel this could be changed to some list of "active" hardware
accelerators (like the list of available hw accels). Then multiple
hw_device_ctx can be active in one execution of the FFmpeg.
I hope someone would like to implement this. The rewrite of the ffmpeg.c
doesn't need to be "massive" as for each filter just only one
"hw_device_ctx" can be used. So the change only implies to the
initialization section and to pass the correct context to each filter.
You agree?
