* Prevent integer underflows in ID3::IteratorJoshua J. Drake2016-03-221-0/+3
| | | | | | | | | | | If mFrameSize is less than or equal to getHeaderLength(), an integer underflow will occur. This typically leads to a crash reading out of bounds in the following code. Prevent this from happening by validating mFrameSize. Also add NULL checks after references to ID3::Iterator::getData. Bug: 23285887 Change-Id: I35eeda3c5349ebbd9ffb3ea49b79af6a940d1395

* Benign integer overflow in PlaylistFetcherDan Austin2015-11-051-1/+2
| | | | | | | | | There is a benign integer overflow in the loop that finds the smallest first PTS from all streams in the current parser. The loop has been refactored to eliminate the integer overflow. Bug: 25008541 Change-Id: Ie2c0f1d360023cad960e071d810dddb1b5420470

* HLS: temporarily blacklist a variant if failed to fetchChong Zhang2015-07-143-14/+145
| | | | | | | | | | | | | | - 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 Zhang2015-03-274-315/+752
| | | | | | | | | | | | | | | | | | | | | - 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 Zhang2015-03-204-277/+563
| | | | | | | | | | | | | | | | | | - 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 Zhang2015-03-193-69/+149

| | | | | | | | | | | | | | | | | | | | | | - keep old fetcher when seeking, unless the URI is changing. - when restarting after a seek, check discontinuity seq, and queue format change if it's changed. - add a simple kill switch to abort when stop (or pause for seek). - when seeking, if searching for start time goes into 2nd segment, do not signal time discontinuity or reset first PTS. - use setFormat() to set format in AnotherPacketSource, otherwise video/audio flags are not updated and format are not cleared on discontinuities. - do not start queueing video access unit until first IDR after start bug: 19656539 Change-Id: I79108d26964f59ea00d2eeac8f5f9318747f8541

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bandwidth switch down is triggered if the buffered duration in any of the current packet sources is below a threshold. When a switch is in progress, all the packet sources are drained until they are empty or until stop time is dequeued. Hence buffered duration keeps going down during switch. Defering check switch down will avoid unnecessary switches. Do not switch down if estimated bandwidth index is more than the current one.
