Sorry, i didn't see the 'did this work before' part. It did work maybe one or two weeks earlier. I failed to notice when it stopped working as i worked on some other project.

Unable to reproduce the issue on ubuntu 17.10 using chrome reported version #67.0.3396.87 (Developer Build).

Following are the steps followed to reproduce the issue.
------------
1. Start chromium as follows: chromium --password-store=basic --allow-file-access-from-files --kiosk --autoplay-policy=no-user-gesture-required /home/techm/Downloads/test
2. Observed that the chromium played the video without any issues.

As the issue is reported on Debian 9.4. Hence, forwarding the issue to inhouse team for further triaging of the issue.

Thanks...!!

Thank you for your work. I was able to test on 2 Debian systems and the issue happened both times. Maybe it is a Debian failure. However the system default video player managed to play the video file on both machines. May that be that chromium and "Debian default video player" (whatever that is) uses different codec binaries or video type recognizing software?

I'm willing to provide teamviewer access to the machine if needed.

Able to reproduce this issue on reported version chromium 67.0.3396.99 and latest canary chromium 69.0.3494.0 using debian.

This issue is seen from M-60. As this issue is seen from older builds considering this issue as Non-Regression, marking as Untriaged and removing Needs-Bisect label.

Observations:
1. Issue is only seen in chromium builds and not seen in chrome builds.
2. Error Observed [1:15:0716/152404.140952:ERROR:render_media_log.cc(30)] MediaEvent: MEDIA_ERROR_LOG_ENTRY {"error":"FFmpegDemuxer: no supported streams"}
[1:1:0716/152404.141156:ERROR:render_media_log.cc(30)] MediaEvent: PIPELINE_ERROR DEMUXER_ERROR_NO_SUPPORTED_STREAMS.

Thanks!
