Media Debugging Tips: Difference between revisions

For DRM content (Amazon Prime, Netflix) it can be helpful to generate EME related logging. Logs are generated for both the browser and Gecko Media Plugin (GMP) child processes. The steps to produce these logs are bit more involved compared to basic media playback logging but are worth the effort when tracking down drm related issues.

'''General testing setup steps'''

# Install [https://www.mozilla.org/en-US/firefox/channel/desktop/ Firefox Nightly] on the test device and open the browser. The test device should be a clean system that has not had Firefox installed on it prior. If the test device does have existing Firefox installs, open Firefox Nightly and open about:profiles. Create a [https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles new profile for testing purposes], and launch a browser using this profile.

# Once Firefox is open and running in a clean profile, check for browser updates via the Help menu -> About option. If there are browser updates available, apply them and then restart the browser.
