For some cases, the regions of interest do not change, it is not
convenient to always prepare the roi data for every frame. So, add
use_last_roi to show it uses the same roi data as last frame.
Since a new flag is added into AVFrame, the major version number of
lavu is changed.

Hi,
I am looking for some guidance regarding future plans about processing subtitle
streams in filter graphs.
Please correct me where I'm wrong - this is the situation as I've understood it
so far:
- Currently, ffmpeg filter graphs do not support processing subtitle streams
- This is why filte

Hi!
Attached patch allows detecting s16 truehd streams encoded with
FFmpeg, only tested with FFmpeg's encoder, I did not look into any

rw_timeout is the generic URLcontext option, not the protocol specific timeout
option, also ?rw_timeout never worked because ?timeout was parsed instead.

After f8990c5f414d4575415e2a3981c3b14ca3d4 we properly set non-blocking
mode which makes the connect() call return always 0 even if no connection can

Fix this by always doing a poll after calling connect(). Also there was some

If i is greater than 0, it is a requirement of bitstream conformance that
point_y_value[ i ] is greater than point_y_value[ i - 1 ].
If i is greater than 0, it is a requirement of bitstream conformance that
point_cb_value[ i ] is greater than point_cb_value[ i - 1 ].
If i is greater than 0, it is

Vulkan is the new standard API for interfacing with GPUs.
A video decode API in on the horizon, and shaders can be used as filters.
FFmpeg is primarily a library, the command line tool is pretty much only
an example implementation.
