Is there a way to Extract frames from .ts files with Http Live Stream in iOS
12 mai 2016, par user1529412I have a current setup in iOS app that streams directly from RTSP and I use ffmpeg library in objective C to extract frames and convert them to RGB/YUV and display them consecutive RGB pics (Video like).
I have a new requirement for HTTP Live Stream (HLS) which requires .ts files and m3u8 index file. I can play the ts files with AVPlayer, but its not what I am looking for, I want to apply my custom OpenGL View like the baove RTSP, so I need access to the actual frames of the ts, because I need the finer control over the frames to apply some OpenGL manipulation. Does anyone know how I can get at the frames of the .ts in Objective-C ?

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
