* HTTP: improve performance by reducing forward seeksJoel Cunningham2017-02-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit optimizes HTTP performance by reducing forward seeks, instead favoring a read-ahead and discard on the current connection (referred to as a short seek) for seeks that are within a TCP window's worth of data. This improves performance because with TCP flow control, a window's worth of data will be in the local socket buffer already or in-flight from the sender once congestion control on the sender is fully utilizing the window. Note: this approach doesn't attempt to differentiate from a newly opened connection which may not be fully utilizing the window due to congestion control vs one that is. The receiver can't get at this information, so we assume worst case; that full window is in use (we did advertise it after all) and that data could be in-flight The previous behavior of closing the connection, then opening a new with a new HTTP range value results in a massive amounts of discarded and re-sent data when large TCP windows are used. This has been observed on MacOS/iOS which starts with an initial window of 256KB and grows up to 1MB depending on the bandwidth-product delay. When seeking within a window's worth of data and we close the connection, then open a new one within the same window's worth of data, we discard from the current offset till the end of the window. Then on the new connection the server ends up re-sending the previous data from new offset till the end of old window. Example (assumes full window utilization): TCP window size: 64KB Position: 32KB Forward seek position: 40KB * (Next window) 32KB |--------------| 96KB |---------------| 160KB * 40KB |---------------| 104KB Re-sent amount: 96KB - 40KB = 56KB For a real world test example, I have MP4 file of ~25MB, which ffplay only reads ~16MB and performs 177 seeks. With current ffmpeg, this results in 177 HTTP GETs and ~73MB worth of TCP data communication. With this patch, ffmpeg issues 4 HTTP GETs and 3 seeks for a total of ~22MB of TCP data communication. To support this feature, the short seek logic in avio_seek() has been extended to call a function to get the short seek threshold value. This callback has been plumbed to the URLProtocol structure, which now has infrastructure in HTTP and TCP to get the underlying receiver window size via SO_RCVBUF. If the underlying URL and protocol don't support returning a short seek threshold, the default s->short_seek_threshold is used This feature has been tested on Windows 7 and MacOS/iOS. Windows support is slightly complicated by the fact that when TCP window auto-tuning is enabled, SO_RCVBUF doesn't report the real window size, but it does if SO_RCVBUF was manually set (disabling auto-tuning). So we can only use this optimization on Windows in the later case Signed-off-by: Joel Cunningham <joel.cunningham@me.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* opus: add a native Opus encoderRostislav Pehlivanov2017-02-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This marks the first time anyone has written an Opus encoder without using any libopus code. The aim of the encoder is to prove how far the format can go by writing the craziest encoder for it. Right now the encoder's basic, it only supports CBR encoding, however internally every single feature the CELT layer has is implemented (except the pitch pre-filter which needs to work well with the rest of whatever gets implemented). Psychoacoustic and rate control systems are under development. The encoder takes in frames of 120 samples and depending on the value of opus_delay the plan is to use the extra buffered frames as lookahead. Right now the encoder will pick the nearest largest legal frame size and won't use the lookahead, but that'll change once there's a psychoacoustic system. Even though its a pretty basic encoder its already outperforming any other native encoder FFmpeg has by a huge amount. The PVQ search algorithm is faster and more accurate than libopus's algorithm so the encoder's performance is close to that of libopus at zero complexity (libopus has more SIMD). The algorithm might be ported to libopus or other codecs using PVQ in the future. The encoder still has a few minor bugs, like desyncs at ultra low bitrates (below 9kbps with 20ms frames).

* opus_celt: rename structures to better names and reorganize themRostislav Pehlivanov2017-02-14
| | | | | | | | | | | | | | | | | | | | This is meant to be applied on top of my previous patch which split PVQ into celt_pvq.c and made opus_celt.h Essentially nothing has been changed other than renaming CeltFrame to CeltBlock (CeltFrame had absolutely nothing at all to do with a frame) and CeltContext to CeltFrame. 3 variables have been put in CeltFrame as they make more sense there rather than being passed around as arguments. The coefficients have been moved to the CeltBlock structure (why the hell were they in CeltContext and not in CeltFrame??). Now the encoder would be able to use the exact context the decoder uses (plus a couple of extra fields in there). FATE passes, no slowdowns, etc. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>
* opus_celt: move quantization and band decoding to opus_pvq.cRostislav Pehlivanov2017-02-14
| | | | | | | | | | | | | | A huge amount can be reused by the encoder, as the only thing which needs to be done would be to add a 10 line celt_icwrsi, a wrapper around it (celt_alg_quant) and templating the ff_celt_decode_band to replace entropy decoding functions with entropy encoding. There is no performance loss but in fact a performance gain of around 6% which is caused by the compiler being able to optimize the decoding more efficiently.

* aac_latm: Align inband PCE to the start of the payloadAlex Converse2017-02-13
| | | | | | | | | | | A strict reading of the spec seems to imply that it should be aligned to the start of the element instance tag, but that would break all of the samples with PCEs. It seems like a well formed LATM stream should have its PCE in the ASC rather than inband. Fixes ticket 4544

* AVFrame: add an opaque_ref fieldwm42017-02-13
| | | | | | | | | | | | | | | | | This is an extended version of the AVFrame.opaque field, which can be used to attach arbitrary user information to an AVFrame. The usefulness of the opaque field is rather limited, because it can store only up to 32 bits of information (or 64 bit on 64 bit systems). It's not possible to set this field to a memory allocation, because there is no way to deallocate it correctly. The opaque_ref field circumvents this by letting the user set an AVBuffer, which makes the user data refcounted. Signed-off-by: Anton Khirnov <anton@khirnov.net> Merges Libav commit 04f3bd349651.
