* arm64: Add Armv8.3-A PAC support to assembly filesAndre Kempe2022-03-09
| | | | | | | | | | | This patch adds optional support for Arm Pointer Authentication Codes. PAC support is turned on or off at compile time using additional compiler flags. Unless any of these is enabled explicitly, no additional code will be emitted at all. Signed-off-by: André Kempe <andre.kempe@arm.com> Signed-off-by: Martin Storsjö <martin@martin.st>

* libavfilter: vf_scale: Properly take in->color_range into accountMartin Storsjö2022-03-07
| | | | | | | | | | | | | | | | | | | | | While swscale can be reconfigured with sws_setColorspaceDetails, the in/out ranges also need to be set before calling sws_init_context, otherwise the initialization might choose fastpaths that don't take the ranges into account. Therefore, look at in->color_range too, when deciding on whether the scaler needs to be reconfigured. Add a new member variable for keeping track of this, for being able to differentiate between whether the scale filter parameter "in_range" has been set (which should override whatever the input frame has set) or whether it has been configured based on the latest frame (which should trigger reconfiguring the scaler if the input frame ranges change).

Here is how a typical stream looks like in coding order: ┌────────┬─────┬─────┬──────────┐ │ sample | PTS | DTS | keyframe | ├────────┼─────┼─────┼──────────┤ ┊ ┊ ┊ ┊ ┊ │ 53 │ 560 │ 510 │ No │ │ 54 │ 540 │ 520 │ No │ │ 55 │ 530 │ 530 │ No │ │ 56 │ 550 │ 540 │ No │ │ 57 │ 600 │ 550 │ Yes │ │ * 58 │ 580 │ 560 │ No │ │ * 59 │ 570 │ 570 │ No │ │ * 60 │ 590 │ 580 │ No │ │ 61 │ 640 │ 590 │ No │ │ 62 │ 620 │ 600 │ No │ ┊ ┊ ┊ ┊ ┊ In composition/display order: ┌────────┬─────┬─────┬──────────┐ │ sample | PTS | DTS | keyframe | ├────────┼─────┼─────┼──────────┤ ┊ ┊ ┊ ┊ ┊ │ 55 │ 530 │ 530 │ No │ │ 54 │ 540 │ 520 │ No │ │ 56 │ 550 │ 540 │ No │ │ 53 │ 560 │ 510 │ No │ │ * 59 │ 570 │ 570 │ No │ │ * 58 │ 580 │ 560 │ No │ │ * 60 │ 590 │ 580 │ No │ │ 57 │ 600 │ 550 │ Yes │ │ 63 │ 610 │ 610 │ No │ │ 62 │ 620 │ 600 │ No │ ┊ ┊ ┊ ┊ ┊ Sample/frame 58, 59 and 60 are B-frames which actually depends on the key frame (57). Here the key frame is not an IDR but a "CRA" (Clean Random Access). Initially, I thought I could rely on the sdtp box (independent and disposable samples), but unfortunately: sdtp[54] is_leading:0 sample_depends_on:1 sample_is_depended_on:0 sample_has_redundancy:0 sdtp[55] is_leading:0 sample_depends_on:1 sample_is_depended_on:2 sample_has_redundancy:0 sdtp[56] is_leading:0 sample_depends_on:1 sample_is_depended_on:2 sample_has_redundancy:0 sdtp[57] is_leading:0 sample_depends_on:2 sample_is_depended_on:0 sample_has_redundancy:0 sdtp[58] is_leading:0 sample_depends_on:1 sample_is_depended_on:0 sample_has_redundancy:0 sdtp[59] is_leading:0 sample_depends_on:1 sample_is_depended_on:2 sample_has_redundancy:0 sdtp[60] is_leading:0 sample_depends_on:1 sample_is_depended_on:2 sample_has_redundancy:0 sdtp[61] is_leading:0 sample_depends_on:1 sample_is_depended_on:0 sample_has_redundancy:0 sdtp[62] is_leading:0 sample_depends_on:1 sample_is_depended_on:0 sample_has_redundancy:0 The information that might have been useful here would have been is_leading, but all the samples are set to 0 so this was unusable. Instead, we need to rely on sgpd/sbgp tables. In my case the video track contained 3 sgpd tables with the following grouping types: tscl, sync and tsas. In the sync table we have the following 2 entries (only): sgpd.sync[1]: sync nal_unit_type:0x14 sgpd.sync[2]: sync nal_unit_type:0x15 (The count starts at 1 because 0 carries the undefined semantic, we'll see that later in the reference table). The NAL unit types presented here correspond to: libavcodec/hevc.h: HEVC_NAL_IDR_N_LP = 20, libavcodec/hevc.h: HEVC_NAL_CRA_NUT = 21, In parallel, the sbgp sync table contains the following: ┌────┬───────┬─────┐ │ id │ count │ gdi │ ├────┼───────┼─────┤ │ 0 │ 1 │ 1 │ │ 1 │ 56 │ 0 │ │ 2 │ 1 │ 2 │ │ 3 │ 59 │ 0 │ │ 4 │ 1 │ 2 │ │ 5 │ 59 │ 0 │ │ 6 │ 1 │ 2 │ │ 7 │ 59 │ 0 │ │ 8 │ 1 │ 2 │ │ 9 │ 59 │ 0 │ │ 10 │ 1 │ 2 │ │ 11 │ 11 │ 0 │ └────┴───────┴─────┘ The gdi column (group description index) directly refers to the index in the sgpd.sync table. This means the first frame is an IDR, then we have batches of undefined frames interlaced with CRA frames. No IDR ever appears again (tried on a 30+ seconds sample). With that information, we can build an heuristic using the presentation order. A few things needed to be introduced in this commit: 1. min_sample_duration is extracted from the stts: we need the minimal step between sample in order to PTS-step backward to a valid point 2. In order to avoid a loop over the ctts table systematically during a seek, we build an expanded list of sample offsets which will be used to translate from DTS to PTS 3. An open_key_samples index to keep track of all the non-IDR key frames; for now it only supports HEVC CRA frames. We should probably add BLA frames as well, but I don't have any sample so I prefered to leave that for later It is entirely possible I missed something obvious in my approach, but I couldn't come up with a better solution. Also, as mentioned in the diff, we could optimize is_open_key_sample(), but the linear scaling overhead should be fine for now since it only happens in seek events. Fixing this issue prevents sending broken packets to the decoder. With FFmpeg hevc decoder the frames are skipped, with VideoToolbox the frames are glitching.
* avformat/mov: add parsing for the sgpd sync boxClément Bœsch2022-03-04
| | | | | | | | | | | sgpd means Sample Group Description Box. For now, only the sync grouping type is parsed, but the function can easily be adjusted to support other flavours. The sbgp (Sample to Group Box) sync_group table built in previous commit contains references to this table through the group_description_index field.
