Martin Storsjö	b55e3633d3	rtpdec: Use AVERROR_PATCHWELCOME instead of AVERROR(ENOSYS) for unimplemented features Signed-off-by: Martin Storsjö <martin@martin.st>	9 years ago
Martin Storsjö	70c77fdfc1	rtpdec_vp9: Update header parsing to spec draft 02 Signed-off-by: Martin Storsjö <martin@martin.st>	9 years ago
Martin Storsjö	33b83d89e3	rtpdec_vp9: Make sure to free the temp buffer on close Signed-off-by: Martin Storsjö <martin@martin.st>	9 years ago
Janne Grunau	c267413321	Revert "mmaldec: autodetect by default" since it breaks linking on systems without mmal libraries This reverts commit `33ac77e850`.	9 years ago
wm4	33ac77e850	mmaldec: autodetect by default It qualifies as a system library. Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago
wm4	74beead9bd	mmaldec: limit internal buffering This uses a new MMAL feature, which limits the number of extra frames that can be buffered within the decoder. VIDEO_MAX_NUM_CALLBACKS can be defined as positive or negative number. Positive numbers are absolute, and can lead to deadlocks if the user underestimates the number of required buffers. Negative numbers specify the number of extra buffers, e.g. -1 means no extra buffer, (-1-N) means N extra buffers. Set a gratuitous default of -11 (N=10). This is much lower than the firmware default, which appears to be 96. This is backwards compatible, but needs a symbol only present in newer firmware headers. (It's an enum item, so it requires a check in configure.) Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago
wm4	45a954f5aa	mmaldec: print the MMAL format FourCC automatically Slight simplification. The result is the same. Also, change the wording of the message as requested in patch review. Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago
wm4	84bba36846	configure: fix mmal build dependencies The mmal decoders do not depend on the software decoders. Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago
wm4	ce589940c2	mmaldec: send only a single EOS packet on flushing Fixes apparent mmal_port_disable() freezes in ffmmal_stop_decoder() when calling ffmmal_decode() with flush semantics a large number of times in a row. Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago
wm4	46aaad78c3	mmaldec: correct package buffering accounting The assert in ffmmal_stop_decoder() could trigger sometimes. The packets_buffered counter was indeed not correctly maintained, and packets were not subtracted from it if they were still in the waiting queue. For some reason, this happened especially with VC-1. Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago
wm4	9a382f3639	mmaldec: add vc1 decoding support Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago
Julian Scheel	d52208e8d5	mmaldec: Add mpeg2 decoding support Register mmaldec as mpeg2 decoder. Supporting mpeg2 in mmaldec is just a matter of setting the correct MMAL_ENCODING on the input port. To ease the addition of further supported mmal codecs a macro is introduced to generate the decoder and decoder class structs.

Julian Scheel	2689bb115c	mmaldec: Fix avpriv_atomic_get usage There is no avpriv_atomic_get, instead avpriv_atomic_int_get is to be used for integers. This fixes building mmaldec.

Anton Khirnov	2e5bde9565	h264: eliminate max_contexts It is always equal to nb_slice_ctx.	9 years ago
Anton Khirnov	e3c9041cfe	h264: allocate some tables per slice contexts, not threads This is more correct and avoids wasting space when frame threading is used.	9 years ago
Anton Khirnov	e065279529	h264: remove an artificial restriction on the number of slice threads This limit is now unnecessary, we can easily support an arbitrary number of threads.	9 years ago
Anton Khirnov	4fd34e639d	h264: remove pointless setting of some variables in loop_filter Those should already be set to the correct values.	9 years ago
Anton Khirnov	9c858ce33f	h264: remove a pointless comment	9 years ago
Anton Khirnov	b77fffa127	h264: make slice threading work with deblocking_filter=1 In such a case, decode the MBs in parallel without the loop filter, then execute the filter serially. The ref2frm array was previously moved to H264SliceContext. That was incorrect, since it applies to all the slices and should properly be in H264Context (it did not actually break decoding, since this distinction only becomes relevant with slice threading and deblocking_filter=1, which was not implemented before this commit). The ref2frm array is thus moved back to H264Context.	9 years ago
Anton Khirnov	370ddc7b38	h264: remove H264Context.pict_type It is not used for anything internally, just exported in the output frames. So remove the indirection and set it directly in frame_start().	9 years ago

Anton Khirnov	7f045c4429	h264: merge ff_h264_free_context() into h264_decode_end() It is no longer called from outside the h264 decoder.	9 years ago
Anton Khirnov	99c554efc8	h264: eliminate low_delay It is always unconditionally initialized in decode_postinit() and then immediately used in one place further below. All the other places where it is accessed are just useless fluff.	9 years ago

Anton Khirnov	0ba471d7d8	h264: eliminate copy_fields It is very fragile against fields being moved and hides what is actually being copied. Copy all the fields explicitly instead.	9 years ago

Anton Khirnov	728d90a0c1	h264: decouple h264_sei from the h264 decoder Make the SEI parsing independent of the H264Context, to allow decoupling the parser from the decoder.	9 years ago

Anton Khirnov	3176217c60	h264: decouple h264_ps from the h264 decoder Make the SPS/PPS parsing independent of the H264Context, to allow decoupling the parser from the decoder. The change is modelled after the one done earlier for HEVC. Move the dequant buffers to the PPS to avoid complex checks whether they changed and an expensive copy for frame threads.	9 years ago

Anton Khirnov	e9f884416c	h264: move reading direct_spatial_mv_pred out of ff_set_ref_count() It has nothing to do with the reference count and so does not belong in this function.	9 years ago
