DXV files seem to misnomer DXT5 and really encode DXT4 with premultiplied alpha.
At least, this is what Resolume alley does. To check, encode some input with
alpha
as "Normal Quality, With Alpha" in Alley, then decode the output with this
change
-- results are true to the original input compared
This function should convert premultiplied alpha to straight, but does the
opposite.

It seems to be caused by movd m0, r1d in libavcodec/x86/rv34dsp.asm? I'm

Thanks for the fix. I had encountered similar artifacts but failed to fix

Alternative patch which eliminates the I/O error, but slightly modifies
the behavior by introducing a two-stage shutdown (the only difference is
the end of the rtmp_close function) which keeps the server open until
the client closes its end.

Hello,
This small PR implements:
* RTMP flow control on the server side - now the server will stop
sending data if it has filled the window and the client hasn't ACKed
* Improves the tear-down by not returning an error when the server
closes

The demuxer opens an internal parser instance in read_timestamp(), which
requires a codec context. There is no need for it to access the FFStream
one which is used for other purposes, it can allocate its own internal
one.
