* avfilter/f_select: yuv will use Y plane only for scenecut detectLimin Wang2019-08-172-9/+13
| | | | | | | | | | | | | | | | At the moment scene change detection score uses all planes to detect scene changes. In this regard this is similar how the frozen frames detection works. However, in classic encoding scene change detection typically only uses the Y plane. We might get more resonable scores for scene change if we also use only the Y plane for calculating the score if the pixel format is YUV. Although this will require additional work once packed YUV formats are added, because for the moment the generic scene sad score calculation has no way to ignore some components in a packed format.

* avformat/matroskadec: Fix seekingAndreas Rheinhardt2019-08-161-1/+1
| | | | | | | | | | | | | | | | | matroska_reset_status (a function that is used during seeking (among other things)) used an int for the return value of avio_seek which returns an int64_t. Checking the return value then indicated an error even though the seek was successfull for targets in the range of 2GB-4GB, 6GB-8GB, ... This error implied that the status hasn't been reset and in particular, the old level was still considered to be in force, so that ebml_parse returned errors because the newly parsed elements were of course not contained in the previously active and still wrongly considered active master element any more.

* fftools: Use right function signature and pointersAndreas Rheinhardt2019-08-153-16/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The option tables of the various fftools (in particular ffprobe) are arrays of OptionDef; said type contains a union of a pointer to void and a function pointer of type int (*)(void *, const char *, const char *) as well as a size_t. Some entries (namely the common entry for writing a report as well as several more of ffprobe's entries) used the pointer to void to store a pointer to functions of type int (*)(const char *) or type int (*)(const char *, const char *); nevertheless, when the functions are actually called in write_option (in cmdutils.c), it is done via a pointer of the first type. There are two things wrong here: 1. Pointer to void can be converted to any pointer to incomplete or object type and back; but they are nevertheless not completely generic pointers: There is no provision in the C standard that guarantees their convertibility with function pointers. C90 lacks a generic function pointer, C99 made every function pointer a generic function pointer and still disallows the convertibility with void *. 2. The signature of the called function differs from the signature of the pointed-to type. This is undefined behaviour in C99 (given that C90 lacks a way to convert function pointers at all, it doesn't say anything about such a situation). It only works because none of the functions this patch is about make any use of their parameters at all. Therefore this commit changes the type of the relevant functions to match the type used for the call and uses the union's function pointer to store it. This is legal even in C90.

* avformat/mpegtsenc: fix PCR generation intervalsMarton Balint2019-08-141-36/+54
| | | | | | | | | | | | | | | | | | | | | | | | PCR generation was based on counting packets for both CBR and VBR streams. Couting packets might have worked for CBR streams (when muxrate was specified) but it only took into account the packets of a service (or the packets of the PCR stream lately), so even that was problematic for multi program streams. The new code works on actual timestamps for both CBR and VBR streams. For VBR streams the behaviour of the old code is simulated by selecting a PCR interval which is the highest multiple of the frame duration but still less than 100 ms. It should be trivial to add support for setting the PCR interval for VBR streams as well in a later patch. The accuracy of PCR packets for CBR streams was greatly improved by preemtively sending them at PCR intervals even if sending the payload of another stream is in progress.

* avformat/mpegtsenc: fix incorrect PCR selection with multiple programsMarton Balint2019-08-141-64/+80
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MPEG-TS muxer had a serious bug related to the use of multiple programs: in that case, the PCR pid selection was incomplete for all services except one. This patch solves this problem and selects a stream to become PCR for each service, preferably the video stream. This patch also moves pcr calculation attributes to MpegTSWriteStream from MpegTSService. PCR is a per-stream and not per-service thing, so it was misleading to refer to it as something that is per-service. Also remove *service from MpegTSWriteStream because a stream can belong to multiple services so it was misleading to select one for each stream. You can check the result with this example command: ./ffmpeg -loglevel verbose -y -f lavfi -i \ "testsrc=s=64x64:d=10,split=2[out0][tmp1];[tmp1]vflip[out1];sine=d=10,asetnsamples=1152[out2]" \ -flags +bitexact -fflags +bitexact -sws_flags +accurate_rnd+bitexact \ -codec:v libx264 -codec:a mp2 -pix_fmt yuv420p \ -map '0:v:0' \ -map '0:v:1' \ -map '0:a:0' \ -program st=0:st=2 -program st=1:st=2 -program st=2 -program st=0 -f mpegts out.ts You should now see this: [mpegts @ 0x37505c0] service 1 using PCR in pid=256 [mpegts @ 0x37505c0] service 2 using PCR in pid=257 [mpegts @ 0x37505c0] service 3 using PCR in pid=258 [mpegts @ 0x37505c0] service 4 using PCR in pid=256 Fixes ticket #8039. v2: a video is stream is preferred if there are no programs, just like before the patch.

* avfilter/vf_convolution: Fix build failuresAndreas Rheinhardt2019-08-141-2/+3
| | | | | | | | | | | | | | | 98e419cb added SIMD for the convolution filter for x64 systems. As usual, it used a check of the form if (ARCH_X86_64) ff_convolution_init_x86(s); and thereby relied on the compiler eliminating this pseudo-runtime check at compiletime for non x64 systems (for which ff_convolution_init_x86 isn't defined) to compile. But vf_convolution.c contains more than one filter and if the convolution filter is disabled, but one of the other filters (prewitt, sobel, roberts) is enabled, the build will fail on x64, because ff_convolution_init_x86 isn't defined in this case.

| | | | | | | | | | | | | | | | | | | | This patch adds a new option to the scale filter which ensures that the output resolution is divisible by the given integer when used together with `force_original_aspect_ratio`. This works similar to using `-n` in the `w` and `h` options. This option respects the value set for `force_original_aspect_ratio`, increasing or decreasing the resolution accordingly. The use case for this is to set a fixed target resolution using `w` and `h`, to use the `force_original_aspect_ratio` option to make sure that the video always fits in the defined bounding box regardless of aspect ratio, but to also make sure that the calculated output resolution is divisible by n so in can be encoded with certain encoders/options if that is required.
