@ -0,0 +1,12 @@
This module is a gstreamer plugin which provides the ability to replace media
data encoded in certain formats with media encoded in another format. There
are two main components, `videoconv` for converting video data provided to
Quartz and Media Foundation, and `audioconv` for converting audio data
provided to XAudio2.
The broad idea is to hash the incoming data and replace it with data looked up
from a cache. If there is a cache miss, then the data is recorded to disk and
instead replaced by "blank" media. The conversion should be transparent to the
application (Wine, FAudio) so no changes are required to the application.
See the accompanying source files for more information.

/* Algorithm
* ---------
*
* The application feeds encoded audio into XAudio2 in chunks. Since we don't have access to all
* chunks in a stream on initialization (as we do with the video converter), we continuously hash
* the stream as it is sent to us. Each "chunk" is identified as the hash of the entire stream up
* to that chunk.
*
* Since chunks are small (~2 kilobytes), this leads to a significant possibility of two different
* streams having identical intro chunks (imagine two streams that start with several seconds of
* silence). This means we need a tree of chunks. Suppose two incoming streams with chunks that
* hash as shown (i.e. identical intro chunks that diverge later):
*
* Stream 1: [AA BB CC DD]
*
* Stream 2: [AA BB YY ZZ]
*
* We record a tree and the transcoder will walk it depth-first in order to reconstruct each unique
* stream:
*
* AA => aa.ptna
* AA+BB => bb.ptna
* AA+BB+CC => cc.ptna
* AA+BB+CC+DD => dd.ptna
* AA+BB+YY => yy.ptna
* AA+BB+YY+ZZ => zz.ptna
*
* Upon playback, we chain each transcoded stream chunk together as the packets come in:
*
* AA -> start stream with aa.ptna
* BB -> play bb.ptna
* CC -> play cc.ptna
* DD -> play dd.ptna
*
* or:
*
* AA -> start stream with aa.ptna
* BB -> play bb.ptna
* YY -> play yy.ptna
* ZZ -> play zz.ptna
*
* or:
*
* AA -> start stream with aa.ptna
* NN -> not recognized, instead play blank.ptna and mark this stream as needs-transcoding
* OO -> play blank.ptna
* PP -> play blank.ptna
* When the Stream is destroyed, we'll record AA+NN+OO+PP into the needs-transcode database
* for the transcoder to convert later.
*
*
* Physical Format
* ---------------
*
* All stored values are little-endian.
*
* Transcoded audio is stored in the "transcoded" Fossilize database under the
* AUDIOCONV_FOZ_TAG_PTNADATA tag. Each chunk is stored in one entry with as many of the following
* "Proton Audio" (ptna) packets as are required to store the entire transcoded chunk:
*
* uint32_t packet_header: Information about the upcoming packet, see bitmask:
* MSB [FFFF PPPP PPPP PPPP PPPP LLLL LLLL LLLL] LSB
* L: Number of _bytes_ in this packet following this header.
* P: Number of _samples_ at the end of this packet which are padding and should be skipped.
* F: Flag bits:
* 0x1: This packet is an Opus header
* 0x2, 0x4, 0x8: Reserved for future use.
*
* If the Opus header flag is set:
* Following packet is an Opus identification header, as defined in RFC 7845 "Ogg
* Encapsulation for the Opus Audio Codec" Section 5.1.
* <https://tools.ietf.org/html/rfc7845#section-5.1>
*
* If the header flag is not set:
* Following packet is raw Opus data to be sent to an Opus decoder.
*
*
* If we encounter a stream which needs transcoding, we record the buffers and metadata in
* a Fossilize database. The database has three tag types:
*
* AUDIOCONV_FOZ_TAG_STREAM: This identifies each unique stream of buffers. For example:
* [hash(AA+BB+CC+DD)] -> [AA, BB, CC, DD]
* [hash(AA+BB+XX+YY)] -> [AA, BB, XX, YY]
*
* AUDIOCONV_FOZ_TAG_AUDIODATA: This contans the actual encoded audio data. For example:
* [AA] -> [AA's buffer data]
* [BB] -> [BB's buffer data]
*
* AUDIOCONV_FOZ_TAG_CODECINFO: This contans the codec data required to decode the buffer. Only
* the "head" of each stream is recorded. For example:
* [AA] -> [
* uint32_t wmaversion (from WAVEFORMATEX.wFormatTag)
* uint32_t bitrate (from WAVEFORMATEX.nAvgBytesPerSec)
* uint32_t channels (WAVEFORMATEX.nChannels)
* uint32_t rate (WAVEFORMATEX.nSamplesPerSec)
* uint32_t block_align (WAVEFORMATEX.nBlockAlign)
* uint32_t depth (WAVEFORMATEX.wBitsPerSample)
* char[remainder of entry] codec_data (codec data which follows WAVEFORMATEX)
* ]

/* Opus is a great fit for our usecase except for one problem: it only supports a few samplerates.
* Notably it doesn't support 44100 Hz, which is a very frequently used samplerate. This bin
* provides a capssetter element which will override the rate we get from Opus with the rate the
* application requested. Similarly, on the transcoder side, we just encode the audio as if it were
* at 48 kHz, even if it is actually at 44.1 kHz.
*
* The downside to this is a small decrease in audio quality. If Opus is most responsive between 20
* Hz and 20 kHz, then when 44.1 audio is converted to 48, we'll gain noise between 18-20 Hz
* (although WMA probably already filtered that out) and start to lose audio above 18,375 kHz. This
* is at the very edge of human hearing, so we're unlikely to lose any noticeable quality.
*
* Resampling is an option, but has some problems. It's significantly more complicated, and more
* CPU-intensive. Also, XAudio2 buffers can be started and ended at arbitrary points, so if we
* start moving audio data from one buffer into another due to resampling, it may result in audible
* artifacts. I think just encoding at the wrong rate is the best compromise. If the application
* actually cared about audio quality, they probably would not have used WMA in the first place.

/* Algorithm
* ---------
*
* Nicely, both Quartz and Media Foundation allow us random access to the entire data stream. So we
* can easily hash the entire incoming stream and substitute it with our Ogg Theora video. If there
* is a cache miss, then we dump the entire incoming stream. In case of a cache hit, we dump
* nothing.
*
* Incoming video data is stored in the video.foz Fossilize database.
*
* Transcoded video data is stored in the transcoded_video.foz Fossilize database.
*
*
* Hashing algorithm
* -----------------
*
* We use murmur3 hash with the seed given below. We use the x32 variant for 32-bit programs, and
* the x64 variant for 64-bit programs.
*
* For speed when hashing, we specify a stride which will skip over chunks of the input. However,
* we will always hash the first "stride" number of bytes, to try to avoid collisions on smaller
* files with size between chunk and stride.
*
* For example, the 'H's below are hashed, the 'x's are skipped:
*
* let chunk = 4;
* let stride = chunk * 3;
* H = hashed, x = skipped
* [HHHH HHHH HHHH HHHH xxxx xxxx HHHH xxxx xxxx HHHH xxxx] < data stream
* ^^^^ ^^^^ ^^^^ stride prefix, hashed
* ^^^^ chunk
* ^^^^ ^^^^ ^^^^ stride
* ^^^^ chunk
* ^^^^ ^^^^ ^^^^ stride
* ^^^^ chunk
* ^^^^ ^^^^ stride
