Wenbin Chen	efe2b63c89	doc/examples: Add qsv_transcode example Add qsv_transcode example which shows how to use qsv to do hardware accelerated transcoding, also show how to dynamically set encoding parameters. examples: Normal usage: qsv_transcode input.mp4 h264_qsv output.mp4 "g 60" Dynamic setting usage: qsv_transcode input.mp4 hevc_qsv output.mp4 "g 60 asyne_depth 1" 100 "g 120" This command initializes codec with gop_size 60 and change it to 120 after 100 frames Signed-off-by: Wenbin Chen <wenbin.chen@intel.com> Signed-off-by: Haihao Xiang <haihao.xiang@intel.com>	2 years ago

Andreas Rheinhardt	23cb87bb3c	doc/examples/muxing: Remove outdated comment This comment only applies to the scenario in which one uses the AVCodecContexts embedded in AVStreams. Yet this code sample stopped doing so in 9897d9f4e074cdc6c7f2409885ddefe300f18dc7; and the last major version bump even removed the public AVCodecContexts in AVStreams. So just remove this comment.
