How to set min, max and avg bitrate or vbv delay using FFMPEG for livestream in Python ? [closed]
10 mai, par TebyyI'm trying to set the minimum, maximum, and average bitrate or vbv delay for a WebM livestream in Python using FFMPEG, but it still shows "0" or "N/A". I've checked the documentation, and everything seems correct. I've also searched for solutions online, but none of them have solved my problem. Does anyone know what I might be doing wrong and how it should be done correctly ?


FFMPEG Command :


ffmpeg_command = [
 'ffmpeg', '-f', 'rawvideo', '-pix_fmt', 'bgr24',
 '-s:v', '1920x1080', '-r', '60',
 '-i', '-',
 # '-an', # Turn off the audio track
 '-c:v', 'libvpx-vp9', '-g', '60', '-keyint_min', '60',
 '-b:v', '6M', '-minrate', '4M', '-maxrate', '12M', '-bufsize', '8M',
 '-crf', '0', '-deadline', 'realtime', '-tune', 'psnr', '-quality', 'good',
 '-tile-columns', '6', '-threads', '16', '-lag-in-frames', '16',
 '-f', 'webm', '-'
 ]

HEVC with alpha [closed]
3 mai, par foxhableI trying create HEVC with alpha video from png images through ffmpeg.


When i try, it outputs a video that works, has a transparent background and opens in QuickTime, but does not open in Safari. Then i try creating in prores 4444 codec and convert from macOS Context Menu -> Encode Selected Video Files with HEVC 1080p and Preserve Transparency. It has work - video with transparent background, open in QuickTime and in Safari.


So i tried understand what a difference in meta data and only what i find its working video has
HVEC
encoder, but not working hasLavc61.5.103 hevc_videotoolbox
. Can i somehow programmatically or from utilities like ffmpeg create video with HEVC With alpha, which working like from macOS context menu ? macOS context menu doesnt fit because i cant compress or create many videos

Detail info


I have example of working video. Info from ffprobe

Muxing together a .ts file and a sub file causes playback issues in video and audio [closed]
3 mai, par Meta83So I have a .ts file and a converted .dvb sub file (.SRT TO .DVB) that I want to mux togheter using FFMPEG. The mux is a success and the file plays fine in VLC or other modern divce.However I have an older divce (around 10 yeras old) where playback has issues, whenever a line of subs is displayd the picture and and audio gets corrupted and frezzes up and as sson there are no lins everything looks good again and so on. Note that subs are displayd correctly and they are not affected by the issue, only picture and audio is.


I have tried using diffrent command without any luck but here is the most basic command that should work :


ffmpeg -i <video file="file"> -i <dvb file="file"> -f mpegts -c:v copy -c:a copy -c:s copy -copyts <output file="file">
</output></dvb></video>


Here is the output I get frome FFMPEG :

Can anyone help me out ? I'm I missing something that is needed for older divaces (divece in question is a Samsung SMT-S5140 STB).
