We have seen devices running on API21/23 fail transcoding because of setting encoding profile/level. Some devices (ale-123/nexus 7) on API21 returns ENOSYS (Function not implemented) when being configured with a profile setting. (although API21 introduced the capability of setting encoding profile) Some devices (nexus 5) on API23 fails configuration with a specific parameter set, despite advertising support for it. Not setting the baseline profile has no effect on encoding, because when not set, the encoding will pick a suitable profile to use. Since baseline is the lowest possible profile, the auto-picked value can't be worse than baseline. Ref: b/218696352 PiperOrigin-RevId: 427792124
