* HLS: temporarily blacklist a variant if failed to fetchChong Zhang2015-07-141-0/+5
| | | | | | | | | | | | | | - abort high bandwidth immediately when bandwidth is fluctuating - use short-term bandwidth estimate for downswitch if bandwidth is not stable - discard bandwidth samples that's too old in absolute time - if already underflow, switch to lowest bandwidth to catch up - if error happened during bandwidth switch (likely due to new variant link is broken), switch to lowest bandwidth to catch up bug: 21754330 Change-Id: Ifd16d75e261cefb93b989829bf35a36783142ae0

* HLS: faster switching and pause/resume on low bufferChong Zhang2015-03-271-11/+39
| | | | | | | | | | | | | | | | | | | | | - when upswitching, discard excessive buffering on low bandwidth variant, switch to new variant earlier - when downswitching, report newly found IDR positions continuously, and switch as soon as new fetcher passes playback position. This allows us to skip time-consuming resumeUntil() of old fetcher most of the time - implement pause/resume on low buffering, and notify buffering percentage - buffering parameter tuning, separate pause/resume/ready buffer level and up/down switch buffer level, boost up fetcher buffering significantly bug: 19567254 Change-Id: I750dfcc6f861d78d16a71f501beb86d8129cb048
* HLS: allow pause/resume in the middle of a segmentChong Zhang2015-03-201-24/+20
| | | | | | | | | | | | | | | | | | - when down switching, decide whether to finish current segment based on bandwidth settings, abort current segment if needed. - when switching, pause new fetcher after the first 47K chunk, and go back to resume old fethcer to stop point immediately. - when old fetcher reaches stop point, swap packet sources and resume new fetcher. - mark switching as done as soon as old fecther reaches stop point. This allows us to resume bandwidth monitoring earlier, and do subsequent switches sooner. bug: 19567254 Change-Id: Iba4b5fb9b06541bb1e49592536648f5d4cbc69ab
* HLS: bandwidth estimator changesChong Zhang2015-03-191-5/+5
| | | | | | | | | | | | | | | | - separate bandwidth estimator from HTTPBase, so that we have better control on which samples to use, it also allows bandiwdth history across multiple HTTPBase objects (which we'll use later). - use min buffer duration among the streams to decide whether to download next segment. - maintain constant buffer level, time next download to happen when buffer just goes below kMinBufferedDurationUs. bug: 19567254 Change-Id: I5c481ad1f7ff3f084d57ec68856e12ae6b40ce41

* stagefright: httplive: Decouple block size from bandwidth estimateLeena Winterrowd2015-01-281-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | A very small block size in PlaylistFetcher can lead to framework overhead and difficulty streaming high bitrate content, but since HTTPBase keeps a constant history of the past 100 HTTP reads, the block size directly affects bandwidth estimation and in turn, switching latency. Add setBandwidthHistorySize() to HTTPBase to allow setting the history size for bandwidth estimation. Call this within LiveSession based on the current block size to ensure that the number of bytes used for estimating bandwidth does not change if the block size is changed in PlaylistFetcher. Since a single TCP/IP packet can contain up to 64k of data, increase the block size in PlaylistFetcher from 2k to lcm(188, 1024) or 47k to avoid inaccuracies in read timings due to up to a comparable 47 reads from the same locally-cached packet instead of from the network. Also make HTTPBase::addBandwidthMeasurement() virtual to allow bandwidth estimation extensions that do not rely on a history list. Bug: 18821145 Change-Id: I5f957be01f5346e74cfb7eeb150ca4b397ad5798
