| Summary | 0008364: DLNA: WMV streaming doesn't seem to work | ||||
| Description | In the default config, MM always converts to WMV, however, playback always seems to fail--a few seconds of the file play, and then it stops and restarts. Moreover, each time the user tries to play unsuccessfully, another instance of the vhelper app opens and fails to terminate, so that CPU utilization goes to 100%. Tested by: a) Sharing various video files using the default MM DLNA config (which auto-converts to WMV) b) Trying to play with WMP and AirPlayer (iPod) | ||||

As discussed over IM: 1. The problem seems to be in the fact that the PC isn't able to convert the video in real-time and so playback fails on clients side. 2a. To avoid multiple instances of the decoder, we should terminate decoding as soon as downloading of other content starts from the same client. 2b. We could also terminate after some time when the current content is no longer being downloaded by the client. This shouldn't be too soon, as the client can only be paused. So maybe something like 5-10 minutes? However, since most content is converted by then anyway, it probably isn't too useful. |

Both is fixed in build 1433. i.e. The playback continues even if PC isn't able to convert the video in real-time. The file conversion is terminated whenever another conversion is reqested from the same DLNA client. Something that could be improved is the conversion criteria defaults so that conversion is real-time on most PCs, it isn't real time on mine and Michal's PC and thus playback is not fluently. Michal, any idea experience which parameters would speed up the conversion? |

Reopening, because of speed up tweaks. 1) we should limit output size by default, it has quite big influence on speed. I would set default max. size to 640x480. 2) we should use WMV8 codec by default. WMV9 is 2-3times slower. |
