* fftools/ffprobe: Loop over correct number of streams when flushing decodersDerek Buitenhuis2022-11-071-1/+1
| | | | | | | | | | | | | Some formats like FLV can dynamically add streams during packet reading. FFprobe does check for this and reallocates the global stream info, but does not reallocate InputFrame's streams and decoders when this happens, which, as a result, could have caused flushing to occur on an out of bounds stream index, since the flush loop iterates over fmt_ctx's nb_streams, and not ifile's, despite using ifile's streams. This fixes an out of bounds read and segfult. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

* libavcodec/qsvenc: Add skip_frame support to qsvencWenbin Chen2022-11-075-0/+87
| | | | | | | | | | | | | | | | | Add skip_frame support to qsvenc. Use per-frame metadata "qsv_skip_frame" to control it. skip_frame option defines the behavior of qsv_skip_frame. no_skip: Frame skipping is disabled. insert_dummy: Encoder inserts into bitstream frame where all macroblocks are encoded as skipped. insert_nothing: Similar to insert_dummy, but encoder inserts nothing. The skipped frames are still used in brc. For example, gop still include skipped frames, and the frames after skipped frames will be larger in size. brc_only: skip_frame metadata indicates the number of missed frames before the current frame.

* avcodec/vc1dec: Remove VC-1 decoders->H.263 decoder dependencyAndreas Rheinhardt2022-11-063-15/+31
| | | | | | | | | | | | | | The only thing from the H.263 decoder that is reachable by the VC-1 decoder is ff_h263_decode_init(); but it does not even use all of it; e.g. h263dsp is unused and so are the VLCs initialized in ff_h263_decode_init() (they amount to about 77KB which are now no longer touched). Notice that one could also call ff_idctdsp_init() directly instead of ff_mpv_idct_init(); one could even do so in ff_vc1_init_common().

* avcodec/mpegvideo_dec: Don't use MotionEstContext as scratch spaceAndreas Rheinhardt2022-11-064-17/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Decoders that might use quarter pixel motion estimation (namely MPEG-4 as well as the VC-1 family) currently use MpegEncContext.me.qpel_(put|avg) as scratch space for pointers to arrays of function pointers. (MotionEstContext contains such pointers as it supports quarter pixel motion estimation.) The MotionEstContext is unused apart from this for the decoding part of mpegvideo. Using the context at all is for decoding is actually unnecessary and easily avoided: All codecs with quarter pixels set me.qpel_avg to qdsp.avg_qpel_pixels_tab, so one can just unconditionally use this in ff_mpv_reconstruct_mb(). MPEG-4 sets qpel_put to qdsp.put_qpel_pixels_tab or to qdsp.put_no_rnd_qpel_pixels_tab based upon whether the current frame is a b-frame with no_rounding or not, while the VC-1-based decoders set it to qdsp.put_qpel_pixels_tab unconditionally. Given that no_rounding is always zero for VC-1, using the same check for VC-1 as well as for MPEG-4 would work. Since ff_mpv_reconstruct_mb() already has exactly the right check (for hpeldsp), it can simply be reused. (This change will result in ff_mpv_motion() receiving a pointer to an array of NULL function pointers instead of a NULL pointer for codecs without qpeldsp (like MPEG-1/2). It doesn't matter.)

* avcodec/vc1_block: Remove redundant writeAndreas Rheinhardt2022-11-061-1/+0
| | | | | | | | | vc1_decode_skip_blocks() is only called if the current picture is a P frame. So setting pict_type to AV_PICTURE_TYPE_P is redundant; removing it makes pict_type read-only in vc1_block.c (as it should be). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/vc1dec: Split VC-1 decoders from msmpeg4Andreas Rheinhardt2022-11-064-18/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The only msmpeg4 code that is ever executed by the VC-1 based decoders is ff_msmpeg4_decode_init() and what is directly reachable from it. This is: a) A call to av_image_check_size(), then ff_h263_decode_init(), b) followed by setting [yc]_dc_scale_table and initializing scantable/permutations. c) Afterwards, some static tables are initialized. d) Finally, slice_height is set. The replacement for ff_msmpeg4_decode_init() performs a) just like now; it also sets [yc]_dc_scale_table, but it only initializes inter_scantable and intra_scantable and not permutated_intra_[hv]_scantable: The latter are only used inside decode_mb callbacks which are only called in ff_h263_decode_frame() which is unused for VC-1.* The static tables initialized in c) are not used at all by VC-1 (the ones that are used have been factored out in previous commits); this avoids touching 327KiB of .bss. slice_height is also not used by the VC-1 decoder (setting it in ff_msmpeg4_decode_init() is probably redundant after b34397b4cd780b5692548e7d021ec884c7217dba). *: It follows from this that the VC-1 decoder is not really based upon the H.263 decoder either; changing this will be done in a future commit.

* avcodec/vc1dec: Don't open and close decoder during initAndreas Rheinhardt2022-11-061-10/+1
| | | | | | | | | | | | | | | This is done since 16af29a7a6deff3f6081fca1e36ad96cf8fec77d (and is actually unnecessary, because the tables initialized in ff_msmpeg4_decode_init() are only ever used in vc1_block.c which is only entered after a call to ff_msmpeg4_decode_init()) in a very ugly manner; said manner had the byproduct of involving lots of unnecessary allocations and even opening and closing a hwaccel in case one is used. This commit achieves the aim of 16af29a7a6deff3f6081fca1e36ad96cf8fec77d by initializing the VLCs used by VC-1 in ff_vc1_init_common().

* avcodec/vc1: Don't check for AVCodecContext.codecAndreas Rheinhardt2022-11-061-2/+0
| | | | | | | | | | | | | | | This check has been added in c617bed34f39a122ab1f89581ddce9cc63885383, merging ee769c6a7c1d4ec6560f5e5a6f457b770b10fb33 to fix a possible segfault if AVCodecContext.codec is not set as it may be during parsing. While this fixes the segfault, it has the unfortunate side effect that it makes the output of the parser dependent on whether a decoder is set (and ultimately available). The fix later applied in 5d2be71b9ecf2a88752666a2c4039f4d98419d35 does not have this downside and makes checking AVCodecContext.codec superfluous. So remove this check.
