No, tested with master and slave udp ts stream which switch between the master 
and slave stream
more than five times, it'll cause tons of cc error report and can't be 
recovered.

[FFmpeg-devel] [PATCH 00/10] Vulkan code general/performance improvements

2020-05-15 Thread Lynne

Just posting this as a single email not to spam the ML too much.
Going to push this sometime over the weekend alongside the other 3 patches to 
finish
all work on Vulkan before the next release.
Satisfied with the code, though the last patch is slightly ugly.
Performance improvements out of async code: 78% on a toy GPU with 1 queue for 
an upload+scale
Probably closer to 200% on a discrete GPU with 4 transfer/compute queues.

>From cbf54e68dd253581515d76f930c7e7e8d77809b7 Mon Sep 17 00:00:00 2001
From: Lynne 
Date: Thu, 14 May 2020 00:37:21 +0100
Subject: [PATCH 10/10] lavfi/vulkan: use all enabled queues in the queue
 family

This should significantly improve the performance with certain
filterchains.

The NEON hscale function only supports X8 filter sizes and should only

The immediate usecase for this change is making the hscale checkasm

guards).

This applies the same fix from 718c8f9aa59751bb490e2688acf2b5cb68fd5ad1

Will apply this set (checkasm test + arm + aarch64 asm implementations) 
soon, as it's fairly trivial.

[FFmpeg-devel] [PATCH v2 1/2] checkasm: sw_rgb: Add a test for interleaveBytes

2020-05-15 Thread Martin Storsjö

---
This depends on "checkasm: Add functions for printing pixel buffers".

The existing x86 implementations of interleaveBytes seem to slow
down significantly for unaligned copies (GCC 7.5, Sandy Bridge):

interleave_bytes_c:  36251.6
interleave_bytes_mmx:10038.8
interleave_bytes_mmxext: 58450.3
interleave_bytes_sse2:   57746.3

For the properly aligned case, it behaves better:

interleave_bytes_aligned_c: 36109.8
interleave_bytes_aligned_mmx:6033.8
interleave_bytes_aligned_mmxext: 6473.1
interleave_bytes_aligned_sse2:   6163.1

But Clang (in Xcode 11.3, run on Kaby Lake) seems to beat all the asm
implementations, in its (autovectorized?) C version:

interleave_bytes_c:   9893.0
interleave_bytes_mmx:23153.5
interleave_bytes_mmxext: 43693.8
interleave_bytes_sse2:   55894.8

interleave_bytes_aligned_c:  3456.0
interleave_bytes_aligned_mmx:5780.0
interleave_bytes_aligned_mmxext: 4913.8
interleave_bytes_aligned_sse2:   4154.3

v2: Extended the test further to test all combinations of negative
strides for all three buffers.

Do you have a case to reproduce the cc errors report?


Yes, it's real case which can be reproduced in lab.


Can you share the sample?

just have time to look at the issue, I prefer to add one extra checking for 
!tail to fix
it, it's better than revert. I'll post patch for the fixes.


Applied the revert patches for now, because it seems there are other 
changes requested. Also the documentation should also mention that scene 
change detection depends on metadata.

This looks good to me, although I might be biased :-)



Pushed with amended commit message (I don't think it's necessary to 
mention pixels as it's a more general function for checking and diffing 
rectangular sections of memory).

Adds support for checking corner cases for signed and large
coefficients. Also makes the padded coefficients random data.

I forgot to point out, this is missing an addition to 
tests/fate/checkasm.mak - as the tests are run in separate checkasm 
invocations, we need to add new tests groups there, otherwise they 
aren't run as part of "make fate".




Thanks for the reviews! Pushed with both fixes.

[FFmpeg-devel] [PATCH] avformat/mpegts: Check the next sync byte to avoid incorrectt detected raw packet size

2020-05-15 Thread lance . lmwang

From: Limin Wang 

reanalyze() may misdetect the new packet size as 204, but it's 188 still 
actualy,
it'll cause many cc errors report and cannot be recovered. So it's better to 
check
the next sync byte before skip the extra unused bytes.

Also, it is best to change SIZE_STAT_THRESHOLD from 10 to 100? If the input 
stream has
a master/slave switch serveral times, the raw size can be easily detected by 
mistake.

facedetect is not scene change detection.

Maybe my thoughts isn't complete as I assume user should choose one scene 
detect filter.
One example is facedetect, now we have opencv facedetect, in future, we may add
dnn facedetect and even more, for example, the drawbox care for the face detect
result instead of which filter detect I think. That's my consideration.

That is really bad explanation, Different filters writting to same

Sorry, in fact I intentionally did not use the filter name. At that time, I 
considered
that there may be different filters for scene detection, but for filters that 
use the metadata,
the processing method should be the same. So I didn't use the filter name.

[FFmpeg-devel] [PATCH 1/2] checkasm: sw_rgb: Add a test for interleaveBytes

2020-05-15 Thread Martin Storsjö

---
This depends on "checkasm: Add functions for printing pixel buffers".

The existing x86 implementations of interleaveBytes seem to slow
down significantly for unaligned copies (GCC 7.5, Sandy Bridge):

interleave_bytes_c:  36251.6
interleave_bytes_mmx:10038.8
interleave_bytes_mmxext: 58450.3
interleave_bytes_sse2:   57746.3

For the properly aligned case, it behaves better:

interleave_bytes_aligned_c: 36109.8
interleave_bytes_aligned_mmx:6033.8
interleave_bytes_aligned_mmxext: 6473.1
interleave_bytes_aligned_sse2:   6163.1

But Clang (in Xcode 11.3, run on Kaby Lake) seems to beat all the asm
implementations, in its (autovectorized?) C version:

interleave_bytes_c:   9893.0

Adds support for checking corner cases for signed and large
coefficients. Also makes the padded coefficients random data.

Tested on x86_64 and aarch64.

I forgot to point out, this is missing an addition to 
tests/fate/checkasm.mak - as the tests are run in separate checkasm 
invocations, we need to add new tests groups there, otherwise they aren't 
run as part of "make fate".

Also it uses scd for metadata filter name, which is bad. It should use
full filter name.

Implemented the surface reallocation inside media driver in [1], merged the 
query
support in [2],  verified that it works for both AYUV(or XYUV)/Y410, yuyv422.

And for Y210, it seems to be better to implement render target support in
vaapi_encoder in this patch as well:
{ "YUV422_10", VA_RT_FORMAT_YUV422_10,10, 3, 1, 0 },

Hence patch LGTM with or without above modifications, thx.

^ 8bpp to 14, and to 18, right?


Signed-off-by: Josh de Kock

Adds support for checking corner cases for signed and large
coefficients. Also makes the padded coefficients random data.

Tested on x86_64 and aarch64.




+for (j = 0; j < width; j++) {
+filter[i * width + j] = -((1 << 14) / (width - 1));
+}
+filter[i * width + (rnd() % (width - 1))] = ((1 << 15) - 1);


Actually, shouldn't this be i*width + (rnd() % width)?

LGTM with that addressed.

Synced with Zhong, will keep the restriction for now and apply this set soon.

Re: [FFmpeg-devel] [PATCH v2] avcodec: Add MediaFoundation encoder wrapper

2020-05-15 Thread Martin Storsjö

From: wm4 

This contains encoder wrappers for H264, HEVC, AAC, AC3 and MP3.

This is based on top of an original patch by wm4
. The original patch supported both encoding
and decoding, but this patch only includes encoding.

The patch contains further changes by Paweł Wegner
 (primarily for splitting out the encoding
parts of the original patch) and further cleanup, build compatibility
fixes and tweaks for use with Qualcomm encoders by Martin Storsjö.
---
v2: Added AV_CODEC_CAP_HYBRID, removed a leftover unused AVBSFContext,
added changelog and encoders.text entries, renamed the configure option
and config item to "mediafoundation" instead of "mf", changed the
makefile to keep individual additions of object files for each
individual encoder (so that it isn't compiled if all encoders are
disabled, even if CONFIG_MEDIAFOUNDATION is enabled).


Any further comments on this, or is it ok to be merged now?

Glad to know this format can be used for Vulkan 10bit display. Sounds like
this format can bring more benefit to ffmpeg. Ping for other comments.
