Some older MSM8916 Venus firmware versions also seem to indicate support for encoding HEVC, even though they really can't. This will lead to errors later because hfi_session_init() fails in this case. HEVC is already ignored for "dec_codecs", so add the same for "enc_codecs" to make these old firmware versions work correctly. Signed-off-by: Stephan Gerhold <stephan@gerhold.net> --- This makes Venus work on the Samsung Galaxy S4 Mini VE (MSM8916), which is stuck on a rather old Venus firmware version (1.6-00040). The firmware is signed, so unfortunately I'm not aware of a way to upgrade it... --- drivers/media/platform/qcom/venus/hfi_parser.c | 1 + 1 file changed, 1 insertion(+)
