  • ffmpeg android java. Unable to use single and regular quotes

    14 février 2016, par MalusDarkb

    First off, in the long run I want to implement a speedometer for a MP4 file using Android. I did some research and apparently the best way to do that is through FFmpeg. I decided on using this library : https://github.com/WritingMinds/ffmpeg-android-java . It implements FFmpeg for Android. It was quite simple to include into my project. (Instructions : http://writingminds.github.io/ffmpeg-android-java/)

    I use the following method. As cmd I am using a String in Quotations marks

        ffmpeg.execute(cmd, new ExecuteBinaryResponseHandler() {
    
    ...
    
    };

    Now I was trying to overlay some dynamic text over an MP4 file. I thought I would start trying it with a timestamp. For a timestamp something like this is needed : ... timecode=’02:36:17~;00’ ...

    My Problem is I am getting this error " Unable to find a suitable output format for ’’’. It doesn’t matter if i try to use "\" (escaping) or if i try to use regular quotes. Whenever I use some kind of quotation mark I am getting an error. That makes it impossible to use an dynamic timestamp. I think.

    Does anyone have an idea as to how I can fix this ? Keep in mind the timecode is within a String in an Android(Java) class.

    Thanks in advance for your help

    EDIT :

    Can someone provide me with a working command ? The cmd 1-3 work, but 4 and 5 don’t work (even as String[]).

    cmd4arr and cmd5arr create an new MP4 file. But it has a size of 0KB. The commands seem not to process the frames at all. It always stops with this last line of the Log posted above.

    Edit :

    Answered question : "What how can I use a String [ ] with this Library ? Information on that might fix the other issues."

    Answer : I imported the project as arr before. When it is imported as a regular library you can’t use a normal String anymore but it is implemented as an String[].

  • Playing 120fps in browser between original and re-made video, original is normal speed, new video is slo-mo

    1er mars 2023, par Patrick Vellia

    I 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 :

    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 ?

    I just compared the two video streams :

    


    original:

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.
