    I use git to track *.ass subtitle files.
    Here is example of *.ass file :

    After commit I burn subtitles into video :

    ffmpeg -i video.avi -vf "ass=subtitle.ass" out.avi

    My goal is to show commit date for 10 second at the start of movie. This should be done automatically.

    1) It can be easily done with by modifying subtitle.ass itself, but I can’t do it after commit and there are other reasons.

    2) It can be done by ffmpeg from command line : How to use ffmpeg to add a text to avi video ?

    Problem is that in this case text will be shown for the whole lenght of movie.

    3) I can copy *.ass file to temporary directory, insert date, render and delete *.ass file.

    Is there a simpler way ?

  • how to use ffmpeg to cache a stream

    17 septembre 2018, par Marcel

    i am using the following command to copy a live stream and restream it to a different endpoint. This works Ok , but the problem is that the stream breaks up/buffer occurs on client/stuttering and does not run smoothly or even fails.
    Here is the command i am using

    ffmpeg -loglevel fatal -fflags +igndts -re -i "$1" -acodec copy -vcodec copy -tune zerolatency -f mpegts pipe:1

    $1 is an mpegts http stream url

    what will be the correct command to use for ffmpeg to "cache" few seconds of the input stream (input is mpegts) before emitting the stream out as is ? I hope by caching i can get a smooth playback , no stuttering or buffering on the client side.

    thanks for help !!

  • Video recorded using Kurento is corrupted

    10 avril 2023, par Pranjal Lamba

    We are using Kurento media server v6.6.1 to record a video conference. The web app client which runs on Chrome(Windows, OSX, Android) is using a modified version of one-to-one-call-advanced Kurento sample and the second client is an Android native application which is using Nubomedia webrtcpeer v1.1.1. Nubomedia webrtcpeer uses LibJingle built by io.pristine v11139(released on December 2015). The video and audio is recorded in two separate recorder endpoints by Kurento.

    


    Video conference recordings generated using web app client/s are working properly. But sometimes the video generated using native application contains all the frames within initial few seconds. Please find below download link for the problematic video generated by our Android native application,

    We are testing this feature on a range of Android devices, Nexus 5(Android 6.0.1), Nexus 6(Android 7.1.1), Sony Xperia Z Tablet(Android 6.0.1), Samsung Galaxy Tab A(Android 5.0), OnePlus 3(Android 7.1.1), Xiaomi A1(Android 7.1.1). The issue randomly starts occurring on a bunch of these devices while the others work properly and vice-versa.
