From ba4616b7d9b9324021985fc5ecd9a9acd2f1f0f2 Mon Sep 17 00:00:00 2001 From: Jean-Christophe Trotin Date: Mon, 5 Sep 2016 11:06:30 -0300 Subject: [PATCH] [media] st-hva: add H.264 video encoding support This patch adds the H.264 video encoding capability in the V4L2 HVA video encoder driver for STMicroelectronics SoC (hva-h264.c). The main supported features are: - profile: baseline, main, high, stereo high - level: up to 4.2 - bitrate mode: CBR, VBR - entropy mode: CABAC, CAVLC - video aspect: 1x1 only Signed-off-by: Yannick
