Les vidéos
21 avril 2011, parComme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...) -

Maintaining exact aspect ratio when scaling videos using ffmpeg
31 mai 2012, par SkkardI have a mkv video, which is a mix of multiple resolution recordings, e.g. I have the first few seconds of widescreen 16:9 (1024x576) resolution, and the rest of the video if 4:3 (768x576) resolution. I want to scale this video down 3 times, while copying all the other attributes (audio codec, subtitles etc.). I use
ffmpeg -i -vf scale=iw/2:-1 -acodec copy. Also, VLC detects it's resolution as 720x576.The problem is that after the scaling, the resolution constantly becomes 4:3 (360x288). How can I maintain the dynamic aspect ratio of the input video file i.e. the 16:9 parts to scale to 16:9, while the 4:3 parts scale to 4:3 ?
update
The player size actually changes, atleast in mplayer, when the resolution is switched. I figured out the main problem. It seems each frame is tagged with a Sample Aspect Ratio (SAR), so when the player plays it, it can find the display aspect ratio. This SAR value isn't getting copied over when encoding to MKV. When encoding to MPG, it does get copied over and I get an exact copy, with the player switching sizes, but not with MKV.

Ffmpeg Android - First image is skipped while making a slideshow
17 mars 2021, par M. Bilal AsifIssue : I have 7 images in a list (with different size, resolution and format). I am adding an mp3 audio file and fade effect while making a slideshow with them, as i am trying to do it by following command


val inputCommandinitial = arrayOf("-y", "-framerate", "1/5")
val arrTop = ArrayList<string>()

 //Add all paths
 for (i in images!!.indices) {
 arrTop.add("-loop")
 arrTop.add("1")
 arrTop.add("-t")
 arrTop.add("5") 
 arrTop.add("-i")
 arrTop.add(images!![i].path)
 }

 //Apply filter graph
 arrTop.add("-i")
 arrTop.add(audio!!.path)
 arrTop.add("-filter_complex")

 val stringBuilder = StringBuilder()

 for (i in images!!.indices) {
 stringBuilder.append("[$i:v]scale=720:1280:force_original_aspect_ratio=decrease,pad=720:1280:(ow-iw)/2:(oh-ih)/2,setsar=1,fade=t=in:st=0:d=1,fade=t=out:st=5:d=1[v$i];")
 }

 for (i in images!!.indices) {
 stringBuilder.append("[v$i]")
 }

 //Concat command
 stringBuilder.append("concat=n=${images!!.size}:v=1:a=0,fps=25,format=yuv420p[v]")

 val endcommand = arrayOf("-map", "[v]", "-map", "${images!!.size}:a", "-c:a", "copy", "-preset", "ultrafast", "-shortest", outputLocation.path)
 val finalCommand = (inputCommandinitial + arrTop + stringBuilder.toString() + endcommand)
</string>

But, it skips the first image and shows the rest 6 images and video output duration is 30 seconds, i've been trying since 3 days now


Requirement :
making a slideshow with different format, size, resolution etc, i.e. picked by user from gallery and show in slideshow adding an audio behind, with fade effect
