Issues with using FFmpeg to generate MPEG-DASH files
26 septembre 2022, par Tina JI am using the following
ffmpegcommand to generate MPEG DASH files and manifest. I usesingle_file 1to have a single file for each representation ; so no chunking. But IDK why when I want to play the manifest using ExoPlayer, the video doesn't play from the beginning (rather it starts from around 50s).

ffmpeg -re -i .\video-h264.mkv -map 0 -map 0 -c:a aac -c:v libx264 -b:v:0 800k -b:v:1 300k -s:v:1 320x170 -profile:v:1 baseline -profile:v:0 main -bf 1 -keyint_min 120 -g 120 -sc_threshold 0 -b_strategy 0 -ar:a:1 22050 -use_timeline 1 -single_file 1 -use_template 1 -window_size 5 -adaptation_sets "id=0,streams=v id=1,streams=a" -f dash out.mpd


What is wrong with this ? Is the manifest correct ? Here is the generated mpd :

How to create a video from images with timestamps, sizes and positions with ffmpeg
23 octobre 2022, par MaxouI want to convert a subtitle file (.sup) to a video file with transparency. To do that I convert my .sup file into a multitude of png files listed in a xml file.

I tried to generate a video using this command


ffmpeg -t 20 -s 1920x1080 \
-f rawvideo -pix_fmt yuva420p -i /dev/zero \
-i seq-1.png \
-filter_complex "[0:v][1:v] overlay=25:25:enable='between(t,0,20)'" \
empty.webm


It works but it takes a long time and I only manage to do it with one image.


It is possible to generate a video with all the images (with size, position and timestamp) include in the xml file ?
