* HLS: misc changes in LiveSession buffering logicChong Zhang2015-03-101-5/+1
| | | | | | | | | | | | | | | remove unnecessary time discontinuity move fetcher to separate looper so that download won't block LiveSession poll buffering at 1 sec interval in LiveSession, and switch bandwidth if necessary use fixed 100ms threshold for resumeUntil bug: 19567254 Change-Id: I911e5041364f0858b43f2312756e173db5870a1e

| * stagefright: httplive: Decouple block size from bandwidth estimateLeena Winterrowd2015-01-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

| * stagefright: httplive: Fix deadlock for low duration clipsLeena Winterrowd2015-01-281-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | PlaylistFetcher buffers up to 3 * target-duration bytes of data, but if a stream is slow (ie due to bad network conditions), a buffer threshold of 10s is used to resume playback. This results in an indefinite freeze as PlaylistFetcher has stopped buffering before this threshold. Reduce the 10s threshold to be more in-sync with PlaylistFetcher's buffering size.

| | | | | | | | | | | | | 1. Improve start time: start playback as soon as the target duration or 10s was buffered. 2. Select playlist monitor time based on target duration to avoid continuously missing the boat. 3. If "we miss the boat" we still must request a safe sequence number (last - 3) Change-Id: Ie99c360ac67b152ad9af19e9c6e520016f67e4e3 Signed-off-by: Lajos Molnar <lajos@google.com> Bug: 12060952
