Tested just now; I can't validate 7592 as the sample link is dead, but playback 
of the files in 7891 over network (in either mpv or ffplay) improves 
dramatically with this option set.

[FFmpeg-devel] [PATCH] lavf/tcp: add resolve_hosts option

2019-09-21 Thread Rodger Combs

This can be used to resolve particular hosts offline without affecting
HTTP headers, TLS SNI, or cross-domain redirects. It works similarly to
curl's --resolve option, but without port-specific handling.

This allows reading packets linearly, which prevents large numbers of
unnecessary seeks in poorly-interleaved files with consumer software that
handles those cases well on its own.

Re: [FFmpeg-devel] [PATCH] lavu/hwcontext_qsv: update crop width/height when mapping frames

2019-09-13 Thread Rodger Combs

This happens with any use of the hwmap filter in the derive_device 
configuration with input being HEVC decoded via dxva2 with dimensions that 
aren't 128-pixel-aligned and output being QSV; eg:
ffmpeg.exe -codec:0 hevc -hwaccel:0 dxva2 -hwaccel_output_format:0 dxva2_vld 
test.mkv -filter_complex 
'[0:0]hwmap=derive_device=qsv[0];[0]scale_qsv=format=nv12[1]' -map[1] -codec:0 
h264_qsv output.mkv

[FFmpeg-devel] [PATCH] lavu/hwcontext_qsv: update crop width/height when mapping frames

2019-09-11 Thread Rodger Combs

This fixes an issue where the context could be configured with one resolution,
but incoming frames could have another, and our output AVFrames wouldn't match
the underlying surfaces' resolution, which is usually the value that MFX code
uses.

In particular, this would happen when mapping from DXVA2 decoders, since DXVA2
aligns the width/height fields in its context to the required alignment for
the particular codec being used, and those values are then propagated into the
QSV context, rather than the crop dimensions.

[FFmpeg-devel] [PATCH 1/2] build: add support for building CUDA files with clang

2019-07-30 Thread Rodger Combs

This avoids using the CUDA SDK at all; instead, we provide a minimal
reimplementation of the basic functionality that lavfi actually uses.
It generates very similar code to what NVCC produces.

The header contains no implementation code derived from the SDK.
The function and type declarations are derived from the SDK only to the
extent required to build a compatible implementation. This is generally
accepted to qualify as fair use.

Because this option does not require the proprietary SDK, it does not require
the "--enable-nonfree" flag in configure.

[FFmpeg-devel] [PATCH 6/6] lavf/tls_apple: add support for the new Network framework

2019-06-11 Thread Rodger Combs

Network.framework was added in macOS 10.14/iOS 12, replacing Secure Transport.
Its TLS functionality is (currently) implemented on top of BoringSSL.
Secure Transport is deprecated as of macOS 10.15/iOS 13. It'll likely remain
available for the forseeable future, but it's considered "legacy" and won't
receive new features; most significantly, TLS 1.3. Network.framework also adds
additional functionality (like multipath TCP) that ffmpeg may eventually want
to support.

The new code is behind compile-time checks for header availability, as well
as runtime checks for OS version. The framework is linked weakly, so ffmpeg
built with Network.framework support will continue to work normally on OS
versions prior to macOS 10.14/iOS 12, with the Secure Transport code path
being taken.

Currently, it's not possible to build tls_apple without support for Secure
Transport. I'm not sure if that's a useful case currently, though I suppose
if its headers are ever removed then we'll need to add some compile-time
conditionals.

[FFmpeg-devel] [PATCH 4/6] lavf/tls_apple: link to SecIdentityCreate weakly

2019-06-11 Thread Rodger Combs

This is a private API, so it might go away in a future macOS version.
Linking to it weakly means that if it does, we won't crash during symbol lookup.

[FFmpeg-devel] [PATCH 2/3] FATE/filter-video: fix high-bit-depth yadif tests

2019-01-22 Thread Rodger Combs

These previously upconverted the video _after_ applying the filter, so they
didn't actually test the high-bit-depth code paths at all, which is why the
PMINSD issue in the previous commit wasn't caught. I also added variants with
the spatial check enabled and disabled, so both of those paths are tested (as
with the 8-bit path).

The chroma upconversion to 4:4:4 is deliberate; the upscale results in some
non-multiple-of-4 input values in the 10-bit case, and non-multiple-of-256
values in the 16-bit case, so that the tests would catch problems resulting in
lossy output in the low bits.

[FFmpeg-devel] [PATCH 1/3] lavu/x86util: make imprecise PMINSD implementation opt-in

2019-01-22 Thread Rodger Combs

This caused rounding errors when values that can't be expressed exactly as
32-bit floats were passed in, which could happen in 16-bit yadif

swscale's call is opted in, under the assumption that it never uses values
large enough to run into this (i.e. within 2^24)

That's patent nonsense. Requests for media are as likely to contain 
authentication tokens as anything else today, and users have as much of a right 
to privacy in the specific media they consume as in anything else they use 
online. Without any verification of peer certificates, our current defaults are 
little better than using plaintext.

[FFmpeg-devel] [PATCH 5/5] lavf/tls: enable server verification by default when not on mbedtls

2019-01-18 Thread Rodger Combs

All other TLS wrappers now have a mechanism to load a system trust store
by default, without setting the cafile option. For Secure Transport and
Secure Channel, it's the OS. For OpenSSL and libtls, it's a path set at
compile-time. For GNUTLS, it's either a path set at compile-time, or the
OS trust store (if on macOS, iOS, or Windows). It's possible to configure
OpenSSL, GNUTLS, and libtls without a working trust store, but these are
broken configurations and I don't have a problem with requiring users with
that kind of install to either fix it, or explicitly opt in to insecure
behavior. mbedtls doesn't have a default trust store (it's assumed that the
application will provide one), so it continues to require the user to pass
in a path and enable verification manually.

What kind of misconfiguration are you referring to? The actual verification is 
still gated behind the tls_verify option; if that's set to 0, this won't 
actually do anything. (Well, it'll result in OpenSSL potentially generating a 
different error code internally, and then discarding it because we didn't 
enable verification).

CRYPTO_get_locking_callback is a macro returning NULL on 1.1 and later. This 
triggers -Wtautological-pointer-compare ("comparison of function 'openssl_lock' 
equal to a null pointer is always false"), which suggests "prefix with the 
address-of operator to silence this warning", so I did that. We could 
alternately wrap this code in an OpenSSL version check, but this seemed easier.

[FFmpeg-devel] [PATCH 4/4] lavf/tls: enable server verification by default when not on mbedtls

2019-01-17 Thread Rodger Combs

All other TLS wrappers now have a mechanism to load a system trust store
by default, without setting the cafile option. For Secure Transport and
Secure Channel, it's the OS. For OpenSSL and libtls, it's a path set at
compile-time. For GNUTLS, it's either a path set at compile-time, or the
OS trust store (if on macOS, iOS, or Windows). It's possible to configure
OpenSSL, GNUTLS, and libtls without a working trust store, but these are
broken configurations and I don't have a problem with requiring users with
that kind of install to either fix it, or explicitly opt in to insecure
behavior. mbedtls doesn't have a default trust store (it's assumed that the
application will provide one), so it continues to require the user to pass
in a path and enable verification manually.

Looks like it's been like that since at least 2002. It's probably because a lot 
of code that loops on e.g. avio_r8 checks for EOF, but doesn't explicitly check 
for error, so if errors didn't set the EOF flag, they'd just loop forever. 
Either way, that code needs to be updated to return errors properly, so I don't 
think removing the EOF-on-error behavior is helpful (it'd just make existing 
problem cases worse).

I don't think this can really be resolved generically, since all the places 
that currently just return AVERROR_EOF in this case will need updating to read 
the error from AVIOContext regardless.

[FFmpeg-devel] [PATCH 1/3] lavf/matroskadec: don't treat I/O errors as EOF

2018-11-27 Thread Rodger Combs

pb->eof_reached is set on error, so we need to check pb->error,
even after checking pb->eof_reached or avio_feof(pb), or else we
can end up returning AVERROR_EOF instead of the actual error code.

[FFmpeg-devel] [PATCH] lavf/mpegtsdec: fix AVPacket.pos when FEC/DVHS/BDAV data is present

2018-08-30 Thread Rodger Combs

We previously set pos to several bytes before the actual packet sync byte,
which meant that seeking to pos relied on resync working, which can fail
if there are 0x47 bytes in the additional data.

The resync issue should probably also be fixed separately.

I'd actually sort of prefer that, since it'd let me call avio_feof() instead of 
doing a direct member access, but it turns out that eof_reached is set to 1 in 
error cases as well.

Re: [FFmpeg-devel] [PATCH] avcodec/videotoolbox: fix kVTCouldNotFindVideoDecoderErr trying to decode HEVC on iOS

2018-04-20 Thread Rodger Combs

If there was a way to indicate this to consumers, or expose an option to turn 
this off, I'd say it should have that... but there's no good infrastructure to 
do that in an hwaccel, so whatever.
One nit; otherwise LGTM.

Re: [FFmpeg-devel] [PATCH 07/10] lavf: document that AVStream::codecpar may be modified by lavf after avformat_write_header(). This is assumed not to break API because it's already true (see e.g. matr

2018-03-16 Thread Rodger Combs

Could we just declare that lavf can update extradata (and nothing else) if it 
gets packets with new-extradata side-data? If not, I suppose we could either 
add something to AVStreamInternal, or do something internal in check_bitstream 
(and update movenc and matroskaenc, as both exhibit this behavior right now).

Right, but the format itself doesn't support changing mid-stream; we handle 
that case by rewriting the header.

Happens after the subsequent patch ("lavf/mux: propagate extradata changes 
before we call write_header to codecpar").

[FFmpeg-devel] [PATCH 10/10] lavf/movenc: handle AC3 and EAC3 data extraction in check_bitstream

2018-03-14 Thread Rodger Combs

This allows us to write AC3 and EAC3 data to the header even in non-seekable
output, like with segment.c (which I add tests for).

[FFmpeg-devel] [PATCH 09/10] lavf/mux: propagate extradata changes before we call write_header to codecpar

2018-03-14 Thread Rodger Combs

This includes extradata generated by an encoder post-init, or extradata
generated by automatically-added bsfs.

This fixes remuxing ADTS to non-seekable MKV, which had been broken in
f63c3516577d605e51cf16358cbdfa0bc97565d8, so the tests modified there

This moves extradata writing in aac-autobsf-adtstoasc to write_header,
resulting in a smaller file since we don't write a padding void, so
that test reference is also updated.

[FFmpeg-devel] [PATCH 08/10] lavf/matroskaenc: don't rewrite extradata if we already have some

2018-03-14 Thread Rodger Combs

matroska doesn't support mid-stream extradata changes, and rewriting
the same extradata already written in write_header would cause errors
since we previously didn't write a filler void.

DASH muxing sometimes calls mov_write_eac3_tag multiple times on the same

We need to keep this data around so it's available in the second call, else we

Re: [FFmpeg-devel] [PATCH] lavf/movenc: keep eac3_priv around; fixes eac3 in DASH

2018-03-08 Thread Rodger Combs

Muxing DASH may involve calling mov_write_eac3_tag multiple times on the same 
stream. If we destroy eac3_priv after the first call, we don't have it  later, 
so we end up not writing that data. This is fine for lavf (since everything in 
that atom is redundant), but some other players require it.

[FFmpeg-devel] [PATCH] lavc/videotoolbox: fix threaded decoding

2018-02-02 Thread Rodger Combs

AVHWAccel.end_frame can run on a worker thread. The assumption of the
frame threading code is that the worker thread will change the AVFrame
image data, not the AVFrame fields. So the AVFrame fields are not synced
back to the main thread. But this breaks videotoolbox due to its special
requirements (everything else is fine). It actually wants to update
AVFrame fields.

The actual videotoolbox frame is now stored in the dummy AVBufferRef, so
it mimics what happens in non-videotoolbox cases. (Changing the
AVBufferRef contents is a bit like changing the image data.) The
post_process callback copies that reference to the proper AVFrame field.

Based on a patch by wm4.

(necroing old thread because this came up elsewhere)

I can understand the argument that lavf shouldn't return all of this by 
_default_, but not providing a mechanism at all forces a lot of additional 
boilerplate onto the consumer. It'd be convenient to have an API that does the 
equivalent of what avformat_find_stream_info currently does (determine all 
relevant stream information for all streams, either using parsers or decoders 
as necessary, running through as many frames as necessary to gather the info, 
up to timestamp- and size-based limits).
If you don't think this fits well in lavf, there could be a higher-level lib on 
top of lavf+lavc that handles this sort of thing (potentially the 
"ffmpeg.c-as-a-library" concept I've thought about for a while, with 
ffprobe-like functionality as well), but the simplest way to do it is just to 
have avformat_find_stream_info continue to perform that function, perhaps 
behind a "gather more info than what lavf itself needs" flag.

This is the old read_seek API, so nothing looks at its actual return code 
(apart to check if it's >=0). In the new API, we'd want this, but I think 
moving to that is out of scope for this change.

Not exactly. I'm not using actual wallclock timestamps anywhere; just _offsets_ 
of timestamps.
My application uses ffmpeg.c to record OTA and cable broadcasts (which may have 
corruption) to segments on-disk, which are later either concatenated, or 
streamed to client devices, or both. In either case, it's preferable to have 
timestamps be approximately correct in the event of corruption (as this patch 
produces), rather than entirely absent, or approximated from frame rate (which 
would produce incorrect values if frames were missing). I think the "remux a 
broadcast stream to disk" use-case is fairly common.

As described above, I think the use-case I'm referring to is fairly common and 
worth supporting.

My intended use-case is live streams, where wallclock can be more useful than

unset timestamps on corrupt packets, and another to fill unset DTS from 
wallclock?
