    swresample/rematrix : fix typo in clean_layout()

    av_channel_layout_index_from_channel() takes an AVChannel value, not a mask.

  • Revision 198fa6d0a0 : Add Neon horizontal and vertical vp9_mbloop_filter - The vp9 mbfilter C code wi

    1er juillet 2013, par Frank Galligan

    Changed Paths :
     Modify /vp9/common/arm/neon/vp9_loopfilter_neon.asm


     Modify /vp9/common/vp9_rtcd_defs.sh



    Add Neon horizontal and vertical vp9_mbloop_filter

    - The vp9 mbfilter C code will branch on flat and mask. This CL
    will perform both branches and combine the data. A later CL will
    perform a check to see if all patch will take one branch.
    - These functions are about 1.75 times faster than the C code on
    Nexus 7.

    PS #3
    - Changed all functions to dub limit, blimit, and thresh from
    vld dx[], freeing up r4-r6.
    - Changed code to use vbif to reduce one instruction and free
    up a d register.

  • ffmpeg concat : 2nd video stream frozen, no image

    31 juillet 2016, par Azevedo

    I’m trying to concatenate two video streams with the same econding into one :

    ffmpeg -y -f concat -i parts.txt -c copy join.mkv

    parts.txt

    file part1.mkv
    
file part2.mkv

    ffmpeg will concatenate them but the playback (any player) gives a still image if the playing position corresponds to the 2nd part.
    I tried to switch part1.mkv and part2.mkv to see the results.
    The 1st part (whichever part1 or part2) will play normally but when I seek the playback to the time corresponding the 2nd part the image won’t show, only the audio plays.

    part1
    part2
    What happens if i seek the playback to the 2nd part :
    2nd part on seeking

    UPDATE :
    FULL CONSOLE OUTPUT FOR ffmpeg -y -f concat -i parts.txt -c copy episode.mkv
