  • Video Stabilization with spin product OpenCV

    28 mars 2021, par a.masri

    I'm trying to stabilize video using OpenCV, but my video is a walkaround 360 spin like this spin, but the stabilize not perfect has a shaking because the optical flow not working perfectly with the spined video

    


    can you find python code here

    


    and I'm trying to use FFmpeg but still, have the same issue,

    


    this command

    


    INPUT=$1
STB_OUTPUT=stb1.mp4

ffmpeg -y -i "$INPUT" -vf vidstabdetect=stepsize=32:shakiness=5:accuracy=15:result="$TRF" -f null -

ffmpeg -y -i "$INPUT" -vf vidstabtransform=input="$TRF":smoothing=30,unsharp=5:5:0.8:3:3:0.4  "$STB_OUTPUT"


    


  • ffmpeg decode multiple streams at same time

    29 février 2012, par broschb

    I am using ffmpeg to decode a file and play it back on an android device. I have this working and would now like to decode two streams at the same time. I have read some comments regarding needing to use av_lockmgr_register() call with ffmpeg, unfortunately I am not sure how to use these and how the flow would work when using these locks.

    Currently I have seperate threads on the java side making requests through JNI to native code that is communicating with ffmpeg.

    Do the threads need to be on the native(NDK) side, or can I manage them on the java side ? And do I need to do any locking, and if so how does that work with ffmpeg ?

    ***UPDATE
    I have this working now, it appears that setting up the threads at the java sdk level transfers into separate threads at the native level. With that I was able to create a struct with my variables, and then pass a variable to the native layer to specify what struct to use for each video. So for I have needed to use any mutexs or locks at the native level, and haven't had any issues.

    Does anyone know of potential gotchas I may encounter by not doing so with ffmpeg ?

  • avformat/mpegts : skip non-PMT tids earlier

    9 mai 2018, par Aman Gupta
    avformat/mpegts : skip non-PMT tids earlier

    This mimics the logic flow in all the other callbacks
    
(pat_cb, sdt_cb, m4sl_cb), and avoids calling skip_identical()
    
for non PMT_TID packets.
    

    Since skip_identical modifies internal state like
    
MpegTSSectionFilter.last_ver, this change prevents unnecessary
    
reprocessing on some streams which contain multiple tables in
    
the PMT pid. This can be observed with streams from certain US
    
cable providers, which include both tid=0x2 and another unspecified
    
tid=0xc0.
