* vp9_parser: fix endless loop w/0-sized frameJames Zern2015-10-19
| | | | | | | | treat this the same as an over-sized superframe packet to break out of the parser loop and allow the decoder to fail. Reviewed-by: Ronald S. Bultje <rsbultje@gmail.com> Signed-off-by: James Zern <jzern@google.com>
* vp9_parse: fix parsing of pskip and profile 2/3.Ronald S. Bultje2015-09-04
| | | | | The fate results change because we now correctly timestamp the pskip frames, which means the results are now identical to -vsync 0.

* vp9: assign PTS to visible instead of invisible frameswm42015-02-05
| | | | | | | | | | | | | | All the webm/vp9 files I have seen so far can have packets that contain 1 invisible and 1 visible frame. The vp9 parser separates them. Since the invisible frame is always (?) the first sub-packet, the new packet is assigned the PTS of the original packet, while the packet containing the visible frame has no PTS. This patch essentially reassigns the PTS from the invisible to the visible frame. Reviewed-by: "Ronald S. Bultje" <rsbultje@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* vp9: avoid infinite loop with broken fileswm42015-01-10
| | | | | | | | | | | | | | | With a certain fuzzed file, the parser will always return 0 consumed bytes, which makes calling code call the parser infinitely. Return the full packet size on error instead. (Here it would be nice if parsers could return errors at all.) Additionally, _if_ there's some data left, return that too, which might help with somewhat broken but still somehow playable files. Fixes ticket #4242. Reviewed-by: "Ronald S.

* vp9: fix parser return values in error casewm42015-01-09
| | | | | | | The parser must always set the out_size and out_data pointers. The API seems to require it, and the common code in parser.c also relies on it. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
