  • 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.

  • How to keep compatibility when compiling ffmpeg with android ndk

    2 novembre 2015, par Fido Zhang

    I have successfully compiled ffmpeg as a static library for my project with android-platform 19 which specified in Application.xml as below :

    APP_PLATFORM := android-19

    I test my project on a device(4.4),it runs well. But it will crash on 4.0 devices.

    So I would like to changed the APP_PLATFORM to a lower version like :

    APP_PLATFORM := android-17

    But the ide comes out an error like this.

    libavcodec/ffv1enc.c:631: error: undefined reference to 'log2'

    And when I changed it to a more lower version :

    APP_PLATFORM := android-8

    More errors occured :

    libavcodec/ffv1enc.c:631: error: undefined reference to 'log2'
    
libavutil/mem.c:94: error: undefined reference to 'posix_memalign'

    I know the log2 reference is undefined because of missing libm, but as far as I see Android will automatic link to libm when building.http://mobilepearls.com/labs/native-android-api/ndk/docs/STABLE-APIS.html

    So how can I keep compatibility when compiling ffmpeg in order to run my project well on lower version devices.

  • How to stream frames from ffmpeg to a process ?

    7 mars, par Vorac

    I would like to encrypt camera frames before transmitting. For that purpose the encrypting process needs to get the raw frames through some mode of IPC. I tried reading through the steaming API docs but got lost. This is an "what approach" question instead of a "working solution" one.
