H.264 in Matroska can have blocks with unordered timestamps. Without
passing these as the presentation timestamp into the FFmpeg decoder,
the frames will not be returned in chronological order.
VideoFrame will now include a timestamp that is used by the
PlaybackManager, rather than assuming that it is the same timestamp
returned by the demuxer.
This was used to convert markdown into HTML for display in the browser,
but no other browser behaves this way, so let's simplify things by
removing it.
(Yes, we could implement all kinds of "convert to HTML and display" for
every file format out there, but that's far outside the scope of a
browser engine.)
This URL library ends up being a relatively fundamental base library of
the system, as LibCore depends on LibURL.
This change has two main benefits:
* Moving AK back more towards being an agnostic library that can
be used between the kernel and userspace. URL has never really fit
that description - and is not used in the kernel.
* URL _should_ depend on LibUnicode, as it needs punnycode support.
However, it's not really possible to do this inside of AK as it can't
depend on any external library. This change brings us a little closer
to being able to do that, but unfortunately we aren't there quite
yet, as the code generators depend on LibCore.
We currently bundle AK with LibCore on Lagom. This means that to use AK,
all libraries must also depend on LibCore. This will create circular
dependencies when we create LibURL, as LibURL will depend on LibUnicode,
which will depend on LibCore, which will depend on LibURL.
Previously, a DNS packet containing an invalid name would be returned
with an empty name. With this change, an error is returned if any error
is encountered during parsing.
This commit replaces the 5 fuzzers that previously tested LibTextCodec
with a single fuzzer. We now rely on the fuzzer to generate the
encoding and separate it from the encoded data with a magic separator.
This increases the overall coverage of LibTextCodec and eliminates the
possibility of the same error being generated by multiple fuzzers.
When building fuzzers for Oss-Fuzz using `BuildFuzzers.sh --oss-fuzz`,
fuzzer dictionary files are now copied to the `$OUT` directory. This
allows them to be used automatically by the corresponding fuzzer.
Previously, some fuzzers were generating an excessive amount of debug
logging. This change explicitly disables debug logging for all fuzzers.
This allows higher test throughput and makes the logs easier to read
when fuzzing locally.
Apart from the class used audio fuzzers have identical behavior: Create
a memory stream from the fuzzer input and pass this to the loader, then
try to load audio until an error occurs. Since the loader plugins need
to have the same static create() function anyways for LibAudio itself,
we can unify the fuzzer implementations and reduce code duplication.
This removes a lot of duplicated stream creation code from the plugins,
and also simplifies the way that the appropriate plugin is found. This
mirrors the ImageDecoderPlugin design and necessitates new sniffing
methods on the loaders.
