Issues with adding the current timestamp of a video when using FFPLAY
28 janvier 2023, par lalelarsen1Hi i am trying to add to display the current time of the video as an overlay. i have tried to do follow the answer of this previous post : https://superuser.com/questions/968685/how-to-display-current-time-with-the-ffplay-exe but with no luck.


This is my line of code :


"./ffmpeg-2023-01-25-git-2c3107c3e9-full_build/bin/ffplay.exe" -vf "drawtext=fontfile=./consola.ttf:text='%{pts:hms}':fontsize=48:fontcolor=white:box=1:boxborderw=6:boxcolor=black@0.75:x=(w-text_w)/2:y=h-text_h-20" -i "%shadowplays_folder%\%NEWEST_FOLDER%\%NEWEST_FILE%" -autoexit -x "1000" -alwaysontop


This will display the text "hms}" not the time.


the above code works fine if i replace it with a simple string :


"./ffmpeg-2023-01-25-git-2c3107c3e9-full_build/bin/ffplay.exe" -vf "drawtext=fontfile=./consola.ttf:text='test':fontsize=48:fontcolor=white:box=1:boxborderw=6:boxcolor=black@0.75:x=(w-text_w)/2:y=h-text_h-20" -i "%shadowplays_folder%\%NEWEST_FOLDER%\%NEWEST_FILE%" -autoexit -x "1000" -alwaysontop


This will display the text "test"


what am i missing ?

how to get 120fps encoded video to play at "normal" speed instead of slow mo
1er mars 2023, par Patrick VelliaI used my GoPro Hero10 to record at 4k 120fps on a green screen. This original video plays slo-mo in QuickTime but "normal" speed in the browser. I want it playing normal speed, and if end user wants to slow it down they have the extra frames for that to maintain clarity, which is why I record at 120.


I then used FFMPEG to create an image sequence of the video.


Then I ran Image Magic to create the transparent frames.


Then I put it back together with the following command for a HEVC mov file :


ffmpeg -r 120 -f image2 -i transparent/image_transparent_%08d.png -vcodec hevc_videotoolbox -crf 28 -alpha_quality 1 -tag:v hvc1 output.mov


I am still on an Intel MacBook Pro running FFMPEG 4.6 (as I've found 5+ was buggy with one of my commands a few months ago but can't remember which one, I think it was the videotoolbox).


The GoPro video has the following stream data as input to the FFMPEG :


Duration: 00:00:08.15, start: 0.000000, bitrate: 60160 kb/s
 Stream #0:0(eng): Video: hevc (Main) (hvc1 / 0x31637668), yuvj420p(pc, bt709), 3840x2160 [SAR 1:1 DAR 16:9], 59891 kb/s, 119.88 fps, 119.88 tbr, 120k tbn, 119.88 tbc (default)

 vendor_id : [0][0][0][0]

 Metadata:
 creation_time : 2023-02-28T19:06:41.000000Z
 handler_name : GoPro MET 


Whereas the re-constructed video has the following data :


Duration: 00:00:08.13, start: 0.000000, bitrate: 763650 kb/s
 Stream #0:0: Video: hevc (Main) (hvc1 / 0x31637668), yuv420p(tv, progressive), 3840x2160 [SAR 1:1 DAR 16:9], 763696 kb/s, 120 fps, 120 tbr, 15360 tbn, 15360 tbc (default)
 Metadata:
 handler_name : VideoHandler
 vendor_id : FFMP
 encoder : Lavc58.134.100 hevc_videotoolbo


When this re-constructed video plays in the browser, it is in slow-mo and I need to set the playbackRate to 4.0 for it to play "normally".


Is there something I need to add to the video for the browser to play it at "normal" speed ?


EDIT


I just compared the two video streams :


original:
Stream #0:0(eng): Video: hevc (Main) (hvc1 / 0x31637668), yuvj420p(pc, bt709), 3840x2160 [SAR 1:1 DAR 16:9], 59891 kb/s, 119.88 fps, 119.88 tbr, 120k tbn, 119.88 tbc (default)

Reconstructed:
 Stream #0:0: Video: hevc (Main) (hvc1 / 0x31637668), yuv420p(tv, progressive), 3840x2160 [SAR 1:1 DAR 16:9], 763696 kb/s, 120 fps, 120 tbr, 15360 tbn, 15360 tbc (default)


I don't quit understand all of this though. so here's what I notice :


original. reconstructed
--------------------------------
bt709 progressive
89871 kb/s. 763696 kb/s
119.88 fps. 120 fps
119.88 tbr. 120 tbr
120k tbr. 15360 tbr
11960 tbr. 15360 tbc


Hmm. I suspect it has something to do with tbr and tbc whatever those are, or perhaps the progressive vs the bt709 ? the pirates are also vastly different.

ffmpeg :how to apply animation in multiple images
2 mars 2023, par Pavan GhanateI am trying to merge number of selected images from gallery to a video template in order to make video status or short video in a android app, I am able to merge the selected images in the video using below cammand now i want to add animation


ArrayList<string> cmd2 = new ArrayList<>();
 cmd2.add("-y");
 cmd2.add("-i");
 if (video_temp_path!= null){
 cmd2.add(video_temp_path);
 }else {
 cmd2.add(Environment.getExternalStorageDirectory().getPath()
 + "/Download/happy.mp4");
 }


 for (int no = 0; no < paths.length; no++) {
 cmd2.add("-i");

 cmd2.add(paths[no]);

 }

 cmd2.add("-filter_complex");



 cmd2.add("[0][1]overlay=x=100:y=200:enable='between(t,3,8)'[v1];" +
 "[v1][2]overlay=x=100:y=200:enable='between(t,10,15)'[v2];" +
