Ah, yes of course. If we delay creating the decoder we need to call
begin_frame() again as well.
Please review and/or test the attached patch. Andy I did understand you
right that this is already a Tested-by from your side, isn't it?
I am wondering if calling decode_bitstream one at a time for each
buffer is similar to
calling it with all buffers at once?
Yes, that is correct. It's just not as efficient.
One problem with VA-API is that it doesn't seem to guarantee that
buffers stays around after handing them of to the decoder (the ownership
handling of buffers and surfaces is a totally mess).
So we would need to make a copy of the buffer content to submit it again
all at once.
Regards,
Christian.

Hi Christian,
The new patch leads to seg fault on my system. You forgot to set the
needs_begin_frame to true when the decoder is created. Here's diff for
reference:
Setting true there seems to fix, though only a quick test.
The patch below sets false :-)

I think you are right about the slices, the failing vids are

Thanks for the link, if you have time please give the attached
patch a
try.
It should fix the issue, but I currently don't have a test system for
VAAPI ready so I can't confirm it of hand.
It doesn't fix properly. The vid will play normally after a second,
but during that second I get to see many flash frames of gpu mem.
Lucky I chose this sample out of several as the patch does seem to
fix a couple of other previously failing vids.
Though more testing shows it also regresses previously working vids,
some as
above, but one never "starts" and is total junk.

Subject: [PATCH] st/va: make sure that we call begin_frame() only once v2
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This fixes "st/va: delay calling begin_frame until we have all parameters".
v2: call begin frame after decoder (re)creation as well.
