  • How to find an audio channel layout of a video an then apply it to an another video

    3 janvier 2023, par someCO_OLguy

    We have a video of an audio channel layout, let's say BL. We don't know the format. We need to find the layout of that video and apply to a different video, assuming that each video only has 1 channel.

    


    I tried a lot, and still I can't find an answer that could work

    


  • Gstreamer : how to achieve the same effect as ffmpeg filter tmix

    2 février, par dudengke

    The ffmpeg command can smooth video :

    


    ffmpeg -i 1.h265 -vf "tmix=frames=3:weights=1 1 1" 2.h265


    


    Now i want to use gstreamer to smooth but I can't find the avfilter in gst-libav

    


    gst-launch-1.0 filesrc location=1.h265 ! decodebin ! videoconvert ! avfilter filter="tmix=frames=3:weights=1 1 1" ! videoconvert ! gstsink


    


    My question : Is there another way gstreamer can achieve the same effect as "tmix" in ffmpeg ?
I tried chatGPT, but the effect was not.

    


    gst-launch-1.0 filesrc location=1.h265 ! h265parse ! avdec_h265 ! videoconvert ! tee name=t \
t. ! queue ! identity single-segment=true ! videomixer name=mix sink_0::alpha=0.33 \
t. ! queue ! identity single-segment=true ! mix.sink_1 \
t. ! queue ! identity single-segment=true ! mix.sink_2 \
mix. ! gtksink


    


  • Extract motion vectors from h264 using hardware codec [closed]

    9 juin, par adore

    I am writing program to extract motion vectors from stream (videofile or webcam). While i am using software decoder everything seems ok, but when i trying to change decoder from h264 to h264_rkmpp, then and error, that appears in console :

    


    RgaBlit(1465) RGA_BLIT fail: Invalid argument 
RgaBlit(1466) RGA_BLIT fail: Invalid argument

This output the user parameters when rga call blit fail


    


    I tried to ask chatgpt is there a way to extract motion vectors from h264 stream using hardware decoder h264_rkmpp, and he said that there isn't a way you can do it, if you want to get mvs, then you need to switch decoder back to software h264. So i googled it and didn't found accurate answer on this topic. So i am asking here. Is there a way to get motion vectors (or side data) from h264 stream using hardware decoder like h264_rkmpp ? (ffmpeg)
