|

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.
|
||||
|
||||

/* 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
