• "Transcode" copying video/audio codec

  22 septembre 2012, par JunCTionS

  I took some very shaky video, and went online to try and find how to stabilize it. I came upon this nice blog that uses transcode for it.
  Following the blog instructions it worked very nice, but the end result had a lot of compression artifacts. This I imagine is mostly due to using xvid as a new codec.

  My intention is reuse the codec the camera originally used which is H.264/AVC but I haven't found a way of doing so (ran into various dead ends using either encoder -y mov... or -y ffpmeg.

  In particular when using -y ffmpeg -F "-vcodec copy -acodec copy" it prints out :

  [export_ffmpeg.so] warning: Video template standard must be one of pal/ntsc

  but running

  ffmpeg -i input.mov -vcodec copy -acodec copy output.mov

  Presents no problem.

  Any idea on how to do this ? or an alternative to stabilize video on linux ?.

• FFmpeg HLS Live Stream Stuck with iOS 11

  1er novembre 2017, par Lamorun

  I’ve exp with FFmpeg but i recent problem with iOS 11 (Recent release for Apple)

  I used FFmpeg for stream HLS Live Stream for only iPhone and iPad in closed app for online courses. My problem is the next :

  I used this code for HLS Live Stream :

  ffmpeg -i "Input" -preset fast -c:v libx264 -c:a aac -ac 1 -strict -2 -crf 18 -profile:v baseline -maxrate 1000k -bufsize 1835k -pix_fmt yuv420p -b:a 64k -flags -global_header -hls_time 20 -hls_list_size 6 -hls_wrap 10 -start_number 1 /m3u8/test.m3u8

  This work perfect in iOS 8, 9 and 10 devices. But with new version iOS 11, video is stuck after about 30 to 40 seconds, as seen in the image :

  ios11stuck

  I have searched for hours and hours. I have done many tests, but I can not get it out, since it works perfectly with iOS 8,9 and 10 (test in somes devices, even working perfectly on a device with iOS 10, update to iOS 11, and stop working immediately, downgrade to iOS 10 and work again)

  I hope someone can help me out, thank you and greetings to all
