Nicolas George 44f660e7e7 lavfi: remove FF_LINK_FLAG_REQUEST_LOOP. 
It has no longer any effect.
 2015-09-20 19:02:33 +02:00
Nicolas George 2a351f6c55 lavfi: drop the requirement that request_frame returns a frame. 
It requires a loop in filters or the framework,
that makes the scheduling less efficient and more complex.
This is purely an internal change since the loop is now
present in buffersink.
Note that no filter except buffersink did rely on the requirement.

Nicolas George 7635242ae5 lavfi/vf_idet: remove the loop in request_frame(). 
It is not necessary due to the use of FF_LINK_FLAG_REQUEST_LOOP.
 2015-09-20 18:50:00 +02:00
Nicolas George 807d4b6355 lavfi/buffersink: loop over ff_request_frame(). 
Do not assume that ff_request_frame() returning success
implies a frame has arrived in the FIFO.
Instead, just loop until a frame is in the FIFO.
It does not change anything since the same loop is present
in ff_request_frame(), confirmed by an assertion.

Nicolas George 52c75d486e lavc/hevc: rudimentary support for skip_loop_filter. 
+~9% speed on Core i5 on test sample.

All frames are treated as ref frames, skipping only applies
at level "all". The following mail contains information on
how to improve that:

Nicolas George 6c96aa0606 configure: add a note about pkg-config --static. 
Try to detect "$cc -static" without "pkg-config --static".
Also, when a library detection using pkg-config fails,
make it explicit this was pkg-config.
 2014-12-02 18:43:54 +01:00
Nicolas George cfcaf6b38e configure: add optional pkg-config helper and use it. 
The require variant dies if the package is not present.
The check variant does not import the flags to the used list.
The new variant imports the flags if the package is present
but does not die if it is not.
The new call graph is: require -> use -> check.

Use use_pkg_config for libx264 and libsmbclient: more readable
and three external call less per library.

as specified by the RFC.
 2014-08-17 20:07:27 +02:00
Nicolas George 481cbc5ad5 lavf/http: fix cookie parsing. 
The current code would use any unknown attribute-value pair
as the cookie value.
RFC 6265 states that the first key-value pair is the actual
cookie, and the attribute-value pairs only start after.

With the current code:
Set-Cookie: test=good_value; path=/; dummy=42
gives this:
Cookie: dummy=42
instead of this with the new code:
Cookie: test=good_value

Nicolas George 91244073fd ffmpeg_filter: refuse to configure input without a decoder. 
The decoder is necessary in order to filter frames.
This makes the error message clearer in this case:
currently, it will usually fail because the pixel or sample
format is not defined and is converted into "(null)"
(non-portable).

Nicolas George 099aff5c42 lavfi: check refcount before merging. 
When merging the formats around the automatically inserted
convert filters, the refcount of the format lists can not be 0.
Coverity does not detect it, and suspects a memory leak,
because if refcount is 0 the newly allocated lists are not
stored anywhere. That gives CIDs 1224282, 1224283 and 1224284.
Lists with refcount 0 are used in can_merge_formats(), so the
asserts can not be moved inside the merge functions.

Nicolas George 299a56879d ffmpeg: make reading packets from thread blocking. 
If a packet is not ready on the input selected by ffmpeg,
it will read from another input instead. If that happens
repeatedly, frames will accumulate somewhere later in the
processing to ensure streams synchronization. It can happen
in particular when reading from a slow medium or an
expensive lavfi filter graph.

Make reading from normal demuxers on non-streamed data and
from the lavfi pseudo-device blocking to avoid that.
