  • Ajouter notes et légendes aux images

    7 février 2011, par

    Pour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
    Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.

  • lavf/dashenc : Write media trailers when DASH trailer is written.

    lavf/dashenc : Write media trailers when DASH trailer is written.

    This commit ensures that all (potentially, long) filesystem activity is
    
performed when the user calls av_write_trailer on the DASH libavformat
    
context, not when freeing the context. Also, this defers media segment
    
deletion until after the media trailers are written.

  • ffmpeg or MP4box how to convert video to universal playable Mpeg-DASH or HLS

    17 mars 2021, par Jintor

    What is the "good" way to encode (from any format like webm, rtmp) to UNIVERSALLY PLAYABLE hls or dash format ???

    


    I see tons of talks about HLS and MPEG-DASH with video tag that looks like this

    


    <video width="90%" height="669" controls="controls"> <source src="index.m3u8" type="application/x-mpegURL"> </source></video>&#xA;

    &#xA;

    but what is the good command in FFMPEG ?

    &#xA;

    when I do this

    &#xA;

    ffmpeg -i file.webm  -acodec aac -vcodec libx264 -movflags faststart -s 640x360 -start_number 0 -hls_time 10 -hls_list_size 0 -f hls index.m3u8&#xA;

    &#xA;

    it's playable ONLY in chrome :(

    &#xA;

    but I need it to be playable in safari, firefox, opera, etc

    &#xA;

    I recenlty viewed talks about MP4box, what would be the best line to be able to convert any source to a universal playable stream ?

  • How to set fractional values for `seg_duration` when using ffmpeg's dash muxer ?

    29 décembre 2019, par agconti

    I’m trying to set a fractional value for seg_duration when using ffmepg’s dash muxer like the docs suggest. When I switch between integer decimal values, I don’t get different results. How can I set a fractional value for seg_duration ?

    • E.g. Running my command with seg_duration equal to 1 produces the same minBufferTime as using 0.01.
    • In the source, seg_duration is represented as an int64_t so I don’t see how you can pass a fraction to it.

    Here’s an example ffmpeg command to reproduce :

    ffmpeg -loglevel verbose \
    
-i $INGESTION_PATH \
    
-seg_duration 0.01 \
    
-use_template 1 \
    
-use_timeline 0 \
    
-f dash $OUTPUT_PATH

    Here’s the snippet from the docs on seg_duration :

    seg_duration duration

    Set the segment length in seconds (fractional value can be set). The value is treated as average segment duration when use_template is enabled and use_timeline is disabled and as minimum segment duration for all the other use cases.
