* lavf/dashenc: update bitrates on dash_write_trailerPrzemysław Sobala2017-03-11
| | | | | | | Provides a way to change bandwidth parameter inside DASH manifest after a non-CBR H.264 encoding. Caller now is able to compute the bitrate by itself, after all packets have been written, and then set that value in AVFormatContext->streams->codecpar->bit_rate before calling av_write_trailer. As a result that value will be set in DASH manifest. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* avformat: fix AVStream private fields markerwm42017-03-02
| | | | | | | | | | | | Public fields were added after the private fields (negating the entire point of this). New private fields go into AVStreamInternal anyway. The new marker was set by guessing which fields are supposed to be private and wshich not. recommended_encoder_configuration is accessed by ffserver_config.c directly, and is supposed to use the public API. ffmpeg.c accesses AVStream.cur_dts, even though it's a private field, but that seems to be an older error.
* avcodec, avutil, avformat: remove AVOption requirement for some fieldswm42017-03-02
| | | | | | | | | | Allow all struct fields to be accessed directly, as long as they're public. Before this change, many fields were "public", but could be accessed via AVOption only. This meant they were effectively not public, but were present for documentation purposes, which was incredibly confusing at best.

* 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>

* movenc: add support for track names in ISML manifestsJan Ekström2017-02-12
| | | | | | | | | | | | This enables having multiple tracks of the same type which would be treated as different things by the media server (as opposed to different bit rate versions of the same track). According to the smooth streaming specification, just setting the systemLanguage tag is not enough to note that a track with the same attributes differs from another one.
