  • Overlay Intro Titles/Video in FFMPEG and fix missing keyframes in one step

    23 juin 2021, par Digicrat

    How can I optimally apply an intro video (replacing the few seconds of video with a potentially missing keyframe, but keep the original audio) in one step ?

    


    I have a batch of input videos and a batch of associated (auto-generated) 'intro' videos to overlay on top of them (in this case, replacing the first 3 seconds of video). This is complicated by the fact that some of the input videos were cut in such a way that the first key frame is missing/corrupted in order to achieve the desired audio start point.

    


    My current working (but slow) two-step process is :

    


    ./ffmpeg.exe -i videoA.mp4 -force_key_frames "expr:gte(t,n_forced*3)" videoA-fixed.mp4

./ffmpeg.exe -i videoA-fixed.mp4 -i intro-videoA.mp4 -filter_complex "[0:0][1:0]overlay=enable='between(t,0,3)'[out]" -shortest -map [out] -map 0:1 -pix_fmt yuv420p -c:a copy -c:v libx264 -crf 18 mergedVideo.mp4


    


    I've tried adding the force_key_frames arguments to the latter command, but ffmpeg doesn't seem to like that. Placing it before the filter_complex yields an error "Stream specifier ':0' in filtergraph description [0:0][1:0]overlay=enable='between(t,0,3)'[out] matches no streams."

    


  • Use ffmpeg to move moov atom to front of mp4 file on Google Cloud Platform and Google Cloud Storage

    19 avril 2021, par BlueBoy

    I would like to use ffmpeg to move the moov atom of a .mp4 file to the front of the file so that it can then be streamed.

    


    The .mp4 file is in Google Cloud Storage. I want to take that file and apply the conversion on it (or copy it if needed).

    


    I have successfully run the following command in the terminal and it works. I want to essentially run this command server side on the Google Cloud in a Java environment :

    


    ffmpeg -i input_video_file.mp4 -vcodec copy -acodec copy -movflags faststart output_video_file.mp4

    


    I can get my file from Google Cloud Storage like this :

    


    GcsService gcsService = GcsServiceFactory.createGcsService();
GcsFilename file = new GcsFilename("bucket", "folder/filename;


    


    I was able to find a Java library wrapper for ffmpeg (https://github.com/bramp/ffmpeg-cli-wrapper) but it doesn't seem to allow to move the moov atom. Could anyone help me figure this out further ? Is there a

    


  • Not able to run the final step of running supervisord for plumi

    1er avril 2021, par manic_startup

    on the github page https://github.com/plumi/plumi.app
I am on the final step of Step 6. see below section

    


    =========================

    


    Step 6 : start supervisord
With plumi buildout having finished and ffmpeg installed on our system, it's time to run supervisord :

    


    root@user :/home/plumi.app# ./bin/supervisord

    


    ========================

    


    When I type in the above on CentOS 7 it says "bash : ./bin/supervisord : No such file or directory

    


    I had to change some things in step 5 "Step 5 Install ffmpeg" for the centos section there are two urls in that section pointing to some repos. They did not work so I had to find some other ones on the Internet. The ones I used where.
https://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/e/epel-release-7-13.noarch.rpm

    


    http://ftp.riken.jp/Linux/atrpms/el7-x86_64/atrpms/stable/atrpms-repo-7-7.el7.x86_64.rpm

    


    The first one looks the same but it is different also the only release available was 7-13 so i used that.
The second one is a different url but the file is the same.

    


    also in that section is asks to edit /etc/yum.repos.d/atrpms.repo. It asks to change the base URL to a URL similar to the what is asks when it asked to download from the second repo above. Obviously that url is different now so I changed it to this instead.
http://ftp.riken.jp/Linux/atrpms/el$releasever-$basearch/atrpms/stable/

    


    After this I asks to install ffmpeg this did not work so I used the below guide
https://linuxize.com/post/how-to-install-ffmpeg-on-centos-7/

    


    Then came the section 6 to install supervisord as explained at the start this did not work. Now im stuck !

    


    I have also realised that when I get to the following command in step 4.

    


    ./bin/python bootstrap.py && ./bin/buildout -v

    


    It fails and says "Error : couldn't find distribution for 'hachoir-parser==1.3.4' and bombs out. I have tried to find this file but cant install it and dont know if i even have the correct file. not sure what to do.
