  • Yes or no, will ffmpeg api do hardware decoding on iOS ?

    15 janvier 2019, par Fattie

    There seems to be conflicting information on this.

    https://trac.ffmpeg.org/wiki/HWAccelIntro

    notice the first diagram, it firmly marks iOS as “Y” on VideoToolbox

    enter image description here

    however in the comments down the bottom it says

    VideoToolbox. ​VideoToolbox, only supported on macOS. H.264 decoding is available in FFmpeg/libavcodec.

    And in the confusing second diagram it says "Standalone" is not done for VideoToolbox.

    We have found that using ffmpeg compiled in to iOS .... it seems to not use hardware decoding, which is really a pain.

    1. With avcodec_get_hw_config() we get AV_PIX_FMT_VIDEOTOOLBOX, AV_HWDEVICE_TYPE_VIDEOTOOLBOX which is seemingly correct.

    2. But usage and framerates clearly shows everything is being done in CPU. The code is in ff_hevc_hls_residual_coding all the time. (That’s fffmpeg’s software decoder.)

    3. This very diff very long git.videolan.org URL here seems to suggest again it should all be working.

    4. Have tried every iPhone etc. of course

  • lavc/vc1dsp : fix potential overflow in R-V V inv_trans_4

    lavc/vc1dsp : fix potential overflow in R-V V inv_trans_4

    Judging by the coefficients, the last round of add/sub can overflow
    
to 17 bits with a very small probability just as with the 8-point
    
transform. This is not observed under FATE, but better safe than sorry.

  • TimeStamps using ffmpeg command

    23 janvier 2016, par sudheer babu

    I used the following ffmpeg command

    ffmpeg.exe -f rawvideo -vcodec rawvideo -s 1920x1080 -r 25 -pix_fmt yuv420p -i D:\TestSeqncs\crowd_run_1080p25.yuv -i C:\Users\sree\Desktop\FFmpeg_Experiment\Audio1.mp3 -lavfi "[0:v]split=2[in2][in3];[in2]scale=1280x720[out2];[in3]scale=704x576[out3]" -map 0:v -map "[out2]" -map "[out3]" -map 1:a -c:v libx264 -c:a aac -preset ultrafast -b:v:0 9000K -b:v:1 8000K -b:v:2 7000K -b:a:0 128K muxout.ts " .

    How to get timestamp details of contents in output.ts ? how much delay will be there in output.ts contents ? can anyone have idea ?

    Here my putput is muxout.ts which holds 3 videos and 1 audio. While playing ts i observed delay between streams. How to get those details by using ffmpeg command.

    how to extract details about start time ,duration, if any delays, all these details of all the streams in muxout.ts using ffmpeg command ?
