avcodec/crystalhd : Explicitly set frame pts at all times
23 avril 2017, par Philip Langdaleavcodec/crystalhd : Explicitly set frame pts at all times
Previously, the pts value was initialised to AV_NOPTS_VALUE and so
it was not necessary to always set it. Now, with the new-new decode
API, this is no longer true. I'm not sure why I avoided setting the
pts when the decoder value was also AV_NOPTS_VALUE - it clearly
wouldn't have changed anything previously, but here we are.Failing to do this, means the frame pts will be some random uninitalised
value. -
Image sequence of 1500 frames to loop 30 times in a 30 min video FFMPEG
18 avril 2016, par luch174Really struggling to get this to work, I just need to loop an image sequence. It is 25fps and exactly one second in duration (1500) I need this to basically loop for 30 mins, so it will loop 30 times. Using FFMPEG, here is the working 1500 frames being converted to MP4, like i said it has to be 30 mins in length :
ffmpeg -i "input_%04d.jpg" -c:v libx264 -b:v 1M -s 1080x810 -crf 28 -r 25 -pix_fmt yuv420p out.mp4

Create multiple thumbnails from a video at equal times / intervals
21 mars 2024, par Alexander VakrilovI need to create multiple thumbnails (ex. 12) from a video at equal times using ffmpeg.
So for example if the video is 60 seconds - I need to extract a screenshot every 5 seconds.



Im using the following command to get the frame in the 5ths second.



ffmpeg -ss 5 -i video.webm -frames:v 1 -s 120x90 thumbnail.jpeg




Is there a way to get multiple thumbnails with one command ?
