    MediaSPIP automatically converts uploaded files to internet-compatible formats.

  • FFMPEG : burn SRT files to a transparent video file ?

    19 septembre 2017, par Taapo

    I need to create several versions of srt/ssa subtitles for another editor. To minimize the problems that can rise (encoding, etc) I want to provide a separate AVI file that can be overlayed onto another file.

    So I would like to use FFMPEG to burn an "empty" (transparent) video file which has the length of the subtitle file, and with the subtitles burnt in. How would this be done in FFMPEG ?

    Before someone says this is a bad idea (which someone already did), there are use cases where this technique would be helpful. I’m fully aware that this would create big files, but most real-life editors don’t care about size - but about solutions. Judging from other posts (on other forums) there seem to be a need for others as well. And since a professional subtitler like Lemony Subtitler is offering the option, I suppose this is not really a bad idea.

  • ffmpeg, first second of cut video part freezed

    12 avril 2017, par Hugo

    I need to split video produced by raspivid ( rasbperry pi rasbian video output h264 ) into two parts and second part is always starting with about one second long frozen image. Based on what i found problem is in keyframes.

    I did try following solutions i found :

    • use -ss parameter before -i which should use only keyframes to split - not working, result is same when -ss is before or after -i
    • i did try to extract exact keyframe using ffprobe and to use value pkt_dts_time to specify exact microsecond to split video - again result is same, video is starting with frozen image

    I also try to use -vcodec copy option for both methods but again - result is exactly the some. Only difference i see is delay how long is inicial picture frozen.

  • full screen preview in javacv RecordActivity

    14 avril 2016, par mghaffari

    I use the RecordActivity sample 
    how to set initialize full screen with correct ratio and best resolution in any device and camera ?
    I tested any typical solution for android, but non of them gave me the outcome I wanted. Some of them caused the phone to go heated, and some of them caused the app to stop. 
    If you have any ideas or solutions using which I can use to solve my problem in RecordActivity class, it would be very kind of you to share it with me. Thanks in advance.
