1033344 - 8x10 OMX H.264 encoder requires an encoder reconfig if the framerate changes too much

Status: RESOLVED WONTFIX

(Core :: WebRTC, defect, P4)

Description

[Randell Jesup [:jesup] (needinfo me)]

The 8x10 OMX H.264 encoder requires an encoder reset & IDR when the framerate changes too much; it supports +0% to -50% of the set rate.

We landed a workaround to reset the encoder when we fall outside of that rate.  This forces an IDR and also takes a few frame times in addition, causing a glitch for the user.

It could be avoided by supporting a larger negative size (so we could set the max frame rate, and the camera could go down to 5 or 10fps without a reset), or by allowing a framerate setting change without a reset (which likely would require stagefright changes).

Randell,

The meta build M8610AAAAANFYD1530.1 or later has this fix. Please, confirm and remove the workaround.
