Subject: [FFmpeg-devel] [PATCH 2/2] avcodec/videotoolboxenc: Set default bitrate to zero
Date: Tue, 16 Jul 2024 20:59:53 +0800
Message-ID: <tencent_FE004D687E7FAEAD6638C9C0B9B6F06A420A@qq.com> (raw)
In-Reply-To: <20240716125953.30663-1-quinkblack@foxmail.com>
From: Zhao Zhili <zhilizhao@tencent.com>
Zero is auto mode. From the doc of videotoolbox:
The default bit rate is zero, which indicates that the video
encoder should determine the size of compressed data.
Before the patch, the default bitrate is 200000 setting by
avcodec/options_table, which doesn't work for most of cases.
