html text overlay with ffmpeg [closed]
28 septembre 2020, par TomI have a web page where a user can write html text with online editor tool, ckeditor.com. I want to overlay the html text to a video. My understanding is that ffmpeg doesn't support text overlay with html.


Here are some possible options. I haven't tried any of them. I want to find out which is the better way to doing it.

Parse the html text and convert it to text and settings that ffmpeg supports ? Is it doable ? How difficult is this ?


-
Use puppeteer (server side rendering) to create a png image for image overlay. Would the font rendering on the server side matches 100% with the client side ?


-
Someone suggests to do HTML->PDF->image using imagemagick + mpdf lib to image for image overlay. Many conversions are involved. Sound complex with many points of failure.










Are there other better options ?

What different video formats RTMP streaming support ?
23 octobre 2019, par PadfootIn almost all the online references related to FFMPEG and RTMP, I am getting -f as flv. Is there any other formats.
(I have tried avi, mpeg and h264, but no success.)
Currently, I am running following command -
ffmpeg -re -i video.mp4 -f s16le -ar 48000 -ac 2 -i audio.wav -c copy -f flv rtmp://192.168.0.1:1935/myapp/stream
The issues with -f flv in my case are -
- It doesn’t support 48k sample rate.
- None of my input videos are in flv format (I have to convert it to flv externally).
P.S. - I am using VLC as RTMP player.
EDIT -
I am getting following error with 48k audio file -
[flv @ 0x5650ba7afb80] FLV does not support sample rate 48000, choose from (44100, 22050, 11025)

Stream detect.py script in another device using ffmpeg in yolov5
5 mars 2023, par BubblesI want to stream the detect.py script yolov5 in another device using rtsp (ffmpeg)
for example, when i execute detect.py in cmd using webcam as an input then the live viewing also can stream in another device.


python detect.py --source 0 --weights yolov5s.pt --img-size 640 --conf 0.4 --save-txt --exist-ok | ffmpeg -f rawvideo -pix_fmt bgr24 -s 640x480 -i - -vcodec libx264 -pix_fmt yuv420p -preset ultrafast -f rtsp -rtsp_transport tcp rtsp://192.168.1.3:8554/



The above is the format i follow. However, I try to test it in online rstp viewer and vlc using the ip address and port but it shows the source is offline.


Is it possible to stream yolov5 detect.py script in another device using ffmpeg ?
