  • How to convert a single photo into video with some filters ?

    11 avril 2019, par Zedd W

    I have a picture in jpeg format : cat.

    I converted this picture into a video through some ffmpeg filter : scale and zoompan. The video is that the picture is slowly enlarged

    Then, I encountered some problems when using the following command.

    command 1

    ffmpeg -loop 1 -i cat.jpeg -filter_complex "scale=iw*2:-1,zoompan=z='zoom+0.002':x='iw/2-(iw/zoom/2)':y='ih/2-(ih/zoom/2)':s=720x960" -pix_fmt yuv420p -vcodec libx264 -preset ultrafast -crf 28 -y -t 5 out.mp4

    command 2 (Just adjust the scale value of command 1)

    ffmpeg -loop 1 -i cat.jpeg -filter_complex "scale=iw*8:-1,zoompan=z='zoom+0.002':x='iw/2-(iw/zoom/2)':y='ih/2-(ih/zoom/2)':s=720x960" -pix_fmt yuv420p -vcodec libx264 -preset ultrafast -crf 28 -y -t 5 out.mp4

    Problems :

    1. The picture in the video will zoom in slowly, which is true, but until about the fourth second, the picture will return to the minimum and re-enlarge.Is this the filter parameter I used wrong ?

    2. There is a warning after running the command : [swscaler @ 0x113c66000] Warning: data is not aligned! This can lead to a speed loss. The picture size is 720 x 960 and the video is the same. 720/16 is an integer and 960/16 also an integer. So what not aligned ?

    3. There is another warning : deprecated pixel format used, make sure you did set range correctly. Did I set the pix_fmtparameter wrong ?

    4. command 2 and command 1 are different scale value, But the time they run will vary greatly (If you try to run it). Using a larger scale will have better results. So how to choose a scale value or have better way ?

  • Doing parallel ffmpeg conversions on dozens of servers simultaneously. Is there a better way ? [on hold]

    22 mai 2019, par user15063

    Im currently working on a fairly large site, that requires several thousands of files to be encoded with ffmpeg into flash format (along with thumbnails creation, mobile file encoding). Average encode runs for about 5-15 minutes, as they are fairly large source files. After the job is complete, the outputs need to be shuttled to different servers (flash file to one box, thumbnails to another, mobile file to another, and original file to another).

    During this processes (which is 13 steps at this point) there is a LOT that can go wrong, at any given time (bad files, stuck encodes, network latency, dying servers, spiking lead), so error handling is a bitch.

    Are there any existing solutions for this type of work ? Or do I have to just keep tweaking my homebrew scripts ?
