  • avfilter : Add blue and violet noise generation filters

    avfilter : Add blue and violet noise generation filters

    For the blue and violet noise, I took the pink and brown noise
    
respectively and subtracted the offsets instead of adding them. When I
    
eyeball the frequency spectrum of the resulting outputs it looks correct
    
to me, i.e. the blue graph appears to be a mirror image of the pink, and
    
the same can be said of the violet and the brown. I did not do anything
    
else to confirm the correctness.

  • Correct way of recutting HLS playlist with FFMPEG

    4 juillet 2020, par somerandomusername

    I'm recording a stream on my server and after it finished I need to trim x seconds from the beginning of my video. My stream has master.m3u8 playlist and then 3 sub index_[0|1|2].m3u8 playlists.

    


    I'm trying different methods, they all seem to generate a result, but nothing as I expect.

    


    For example this :

    


    


    ffmpeg -i index_0.m3u8 -ss 30 -strict -2 -hls_time 6 output_0.m3u

    


    


    Seems to generate the correct nr. of *.ts files, but playlist is is only 30s long. Original #EXT-X-TARGETDURATION was set to 6, now it is 8, but actual size is a floating 8.3333...

    


    I'm definitely missing something.

    


    Update 1 :

    


    OK, so I figured out why my *.m3u8 file was to small, by default it only loads last few records in the list so setting -hls_list_size 0 resolved that. Now I need to figure out how to get rid of floating point video sizes.

    


    Update 2 :

    


    It seems that I need -hls_flags split_by_time flag for HLS transmuxer not to ignore my hls_time option. Now my output is even closer to correct result, still have that floating point video size problem.

  • Revision 0ba1542f12 : Vidyo : Support for one-pass rc-enabled SVC encoder Adds support for one-pass rc

    7 novembre 2014, par Deb Mukherjee

    Changed Paths :
     Modify /examples/vp9_spatial_svc_encoder.c


     Modify /vp9/vp9_cx_iface.c


     Modify /vpx/src/svc_encodeframe.c


     Modify /vpx/svc_context.h


     Modify /vpx/vp8cx.h


     Modify /vpx/vpx_encoder.h



    Vidyo : Support for one-pass rc-enabled SVC encoder

    Adds support for one-pass rc-enabled SVC encoder with callbacks for
    getting per-layer packets.
    - the callback function registration is implemented as an encoder
    control function.
    - if the callback function is not registered, the old way of
    aggregating packets with superframe will take effect.
    - one more control function “VP9E_GET_SVC_LAYER_ID” has been
    implemented to get the temporal/spatial id from the encoder
    within the callback. This can be used to get the ids to put on RTP
    packet.
