2.6.0: Video does not load if specifying start time near a segment boundary

[matthew-mahony]

Environment

• [x ] The MPD passes the DASH-IF Conformance Tool on http://dashif.org/conformance.html
• [x ] The stream has correct Access-Control-Allow-Origin headers (CORS)
• [x ] There are no network errors such as 404s in the browser console when trying to play the stream
• [x ] The issue observed is not mentioned on https://github.com/Dash-Industry-Forum/dash.js/wiki/FAQ
• [x ] The issue occurs in the latest reference client on http://reference.dashif.org/dash.js/ and not just on my page

• Link to playable MPD file: http://dash.edgesuite.net/dash264/TestCases/1a/sony/SNE_DASH_SD_CASE1A_REVISED.mpd#s=6
• Dash.js version: 2.6.0
• Browser name/version: Chrome 61
• OS name/version: Windows 8

Steps to reproduce

1. In Dash player 2.6.0, load the mpd http://dash.edgesuite.net/dash264/TestCases/1a/sony/SNE_DASH_SD_CASE1A_REVISED.mpd#s=6. Note the "#s=6" parameter, to start the video at 6 seconds.

Observed behaviour

The player doesn't load correctly. In Dash 2.5.0, the video will load at 6 seconds and start playing. I believe 6 seconds is near a segment boundary. (On a local video, I have this problem at 2 seconds with a video fragmented every 2 seconds).

Hi @matthew-mahony ,

you're right, I can reproduce the issue...in the function onBytesAppended of PlaybackController more precisely. A new PR will be created to fix it.

Nico

I tried your change locally. The video now loads, but not at the specified time. It seems it loads at the beginning of whatever segment the specified time falls into. If I specify 2s, the video loads at 0s. If I specify 4s, it loads around 2s. (My video has 2s segments).

[epiclabsDASH]

Reopening. It is a different issue but seems to come from the same set of previous changes.

[nicosang]

Hi @matthew-mahony,

could you, please, test the new PR #2194 ?

Thanks,
Nico

[epiclabsDASH]

Seems to be fine. I tested the change with smoke test files, played a lot with them and everything worked fine.

@matthew-mahony, please, feel free to close this issue once you confirm it is working fine for you.

Thanks

[matthew-mahony]

This works how I expect now, thanks!

I think this bug still exists for videos without an audio track. See my comment here for more detail:
