  • How to embed pic_timing SEI wall clock timecodes in RTMP streaming ?

    16 mai 2019, par MorenoGentili

    I need to stream my desktop to the AWS MediaLive service and, as a requirement, I must include wallclock timecodes in the stream. The AWS support kindly informed me that for h.264 encoded streams, I need to provide timecodes as "pic_timing SEI messages".

    I’m streaming with Ffmpeg via the RTMP protocol on Windows 10 so, I tried adding the use_wallclock_as_timestamps and copyts flags to my command.

    ffmpeg -f gdigrab -framerate 30 -offset_x 0 -offset_y 0 -video_size 1920x1080 -show_region 1 -use_wallclock_as_timestamps 1 -i desktop -vf scale=320:240 -c:v libx264 -c:a aac -profile:v main -level 3.1 -pix_fmt yuv420p -copyts -f flv rtmp://<ip>:1935/<app>/<stream>
    
</stream></app></ip>

    However, the timecodes are not picked up by AWS MediaLive.

    My questions are :

    • Does the use_wallclock_as_timestamps flag actually create timecodes as "pic_timing SEI messages" as required ?
    • If not, how do I add wallclock timecodes as "pic_timing SEI messages" ? It doesn’t have to be every frame. Every 2 or 3 seconds would suffice.

    I’m stumped. I couldn’t find the answer in the Ffmpeg documentation.

    Thanks for your help.

  • libavfilter/dnn : support multiple outputs for tensorflow model

    libavfilter/dnn : support multiple outputs for tensorflow model

    some models such as ssd, yolo have more than one output.
    

    the clean up code in this patch is a little complex, it is because
    
that set_input_output_tf could be called for many times together
    
with ff_dnn_execute_model_tf, we have to clean resources for the
    
case that the two interfaces are called interleaved.
