Live stream prerecorded video to YouTube using FFMPEG with 4500 kbps bitrate
9 avril 2023, par RsanI tried various ways to make a live streaming script with a bit rate according to YouTube's recommendation of 4500 Kbps bit rate.
The code :


ffmpeg -re -stream_loop -1 -i live1.mp4 -c copy -preset veryfast -b:v 7000k -maxrate 3000k -bufsize 6000k -pix_fmt yuv420p -g 50 -c:a aac -b:a 160k -ac 2 -ar 44100 -f flv -flvflags no_duration_filesize rtmp://a.rtmp.youtube.com/live2/(streamkey)


and in my current code, there is an error when live : Use a keyframe frequency of four seconds or less. Currently, keyframes are sent infrequently which can cause buffering. The current keyframe frequency is 5.0 seconds. Please note that errors in the transfer process can cause the size of the GOP (group of images) to be incorrect.


How to fix my code ?


I've tried several ways, but the bit rate is still high, and the error is in YouTube Studio

How to record the http live streaming from an IP Cam
26 novembre 2012, par abhishekI have created the application in which the client can view the ip camera which is giving
an http live stream of MJPEG using this link
Android ICS and MJPEG using AsyncTaskNow i want the user to record the video into its memory card .
I have googled for a while and the only two approaches which came in my mind :--
Either i keep storing the jpeg images and when user clicks stop recording then i
somehow clip all the images as to provide a 3GP video or some other file format.
But i don't know how to create the video from all the images and will this be an efficient
approach or not. -
Or i do ffmpeg and in this case i will have to deal with NDK and it seems to be a longer
path which may lead to nowhere :P
So is FFMPEG a better option ? If yes please share some links or is the first option better.
Thanks in advance -

Timestamp discontinuity issue in HTTP Live Streaming
25 décembre 2014, par user3663917I was trying to do HTTP Live streaming. The segmentation of the files were done using FFMPEG. The segments are of 5 seconds each. In my case every one minute the PCR values of the input "ts" is reset, ie in the segmented files the segments created after every one minute is having a different range of pcr compared to the previous segments(discontinuity in pcr). These segments work fine in apple devices but in android devices the stream gets stuck after one minute. Is there some method to overcome this issue either in the server side or in the android side ?
