Set the width of text in FFMPEG
7 juin 2020, par Super GadgetsI am currently stuck with ffmpeg issue, I have an online video editor where users can add text and edit it.



So I make an overlay div over the tag to let the user see exactly what the video will look like after render.



But here is the issue : How can I get the css and let ffmpeg apply it on the text, the css will be the div where the transcription is how width, height , margins , colors ...



Here is an example of a box :



<div style="width:100px;text-align:center;top:10px;left:10px> TEXT HERE <div>&#xA;
 ;
 ;
P.s : I tried Aegisub, force_style but no options seems to offer setting the width of the box.

Is there any way to do this ? Thank you.

FFMPEG API : how to use lossless h264 encoding ?
what settings are necessary to use h264 lossless encoding ? I'm not talking about ffmpeg commandline tool, but about the c api.
I manage to encode video with lossy h264, but I don't know how to set the encoder to lossless.?
I code in MSVC++ and use precompiled libraries. online i found some .ffpreset files (for example libx264-lossless_max.ffpreset) which don't seem to be part of the precompiled version i use (at least they are not in the presets folder). I'm not sure whether ffpreset files are somehow compiled into the library, or whether they can be loaded into the encoder somehow ? if so, how would I use such a preset file ?
What to input for variable frame rate in pts / dts in ffmpeg
I am capturing frames from a webcam stream which sends frames in at a variable rate. My output video plays much faster than it was captured because there are less frames available than the input fps.
I’m really new to ffmpeg and don’t know what to put into pts and dts. I can get an Int64 representing nanoseconds since 1600 when the frame arrives. How do I use the av_rescale_q function with it ?
Reading online it seems a solution may be to clone frames so the output fits into a constant frame rate video. However it would be better just to put the timestamp in there.
