#10745 closed Bug Report - General

Myth player not properly resetting after resolution change — at Version 1

Reported by: JYA Owned by: danielk
Priority: minor Milestone: 31.0
Component: MythTV - General Version: Master Head

Description (last modified by JYA)

Attached are 3 samples, all mpeg-ts streams with a H264 video stream and a AAC audio stream

bipbop234.ts is made of 3 x 10s. First block is at 480x320, 2nd and 3rd are at 1280x720. Between 2nd and 3rd it's just a change of video bitrate. This file plays fine with the avfd h264 reset hack. The file exhibit the same problem as #10715

nasa-8s2.ts has a resolution change occurring at 8s... About 30% of the time, myth with the avfd hack will crash and the AAC audio will stop decoding properly.

nasa-27s.ts is like nasa-8s2.ts but with the change over occurring at 27s.

The problem exhibited by those 3 files ultimately is breaking proper handling of HLS stream should the player determine that a lower bitrate stream is to be used.

Note that a recent version of mplayer will play all those files just fine.
