FFmpeg : Get better encoding out of my function
31 octobre 2019, par A PersonI needed some assistance on my task.
I am using FFmpeg to burn time and the channel name onto the video.
My goal is to record a stream that is html5 compatible with the following settings :
Video wrapper MP4
Video codec H.264
Bitrate 1Mbps
Audio codec AAC
Audio bitrate 128Kbps
And
GPU encoding
.This is what I am using :
ffmpeg -hwaccel cuvid -y -i {udp} -vf "drawtext=fontfile=calibrib.tff:fontsize=25:text='{ChannelName} %{localtime}': x=10: y=10: fontcolor=white: box=1: boxcolor=0x000000" -pix_fmt yuv420p -vsync 1 -c:v h264_nvenc -r 25 -threads 0 -b:v 1M -profile:v main -minrate 1M -maxrate 1M -bufsize 10M -sc_threshold 0 -c:a aac -b:a 128k -ac 2 -ar 44100 -af "aresample=async=1:min_hard_comp=0.100000:first_pts=0" -bsf:v h264_mp4toannexb -t 00:30:00 {output}\{ChannelName}\{ChannelName}_{year}_{monthno}_{day}__{Hours}_{Minutes}_{Seconds}.mp4
{ChannelName}_{year}_{monthno}_{day}__{Hours}_{Minutes}_{Seconds}
are all variable holding information.{udp}
holds the UDP stream link.I have done it this way as I have multiple UDP stream recording.
Although this works, is there a better way for me to do this keeping in the
-vf
as I need the time and channel name.Currently, this uses between 0.8% to 1.9% GPU on my Quadro P4000. I don’t want to use more than this as I have more than 30 streams.

fftools/ffmpeg : change frame counters to 64 bit
20 juin 2022, par Marton Balintfftools/ffmpeg : change frame counters to 64 bit
Frame counters can overflow relatively easily (INT_MAX number of frames is
slightly more than 1 year for 60 fps content), so make sure we are always
using 64 bit values for them.A live stream can easily run for more than a year and the framedup logic breaks
on an overflow.Signed-off-by : Marton Balint <cus@passwd.hu>
