  • ffmpeg how to ignore (skip) errors when concatenate and speed up multiple video files

    3 avril 2016, par user1767834

    I'm trying to concatenate many files from my car DVR but some time ffmpeg fails with "Invalid argument" error. My list of files in cf.txt looks like:

    file '2016_0403_170004_098.MOV'
file '2016_0403_170459_099.MOV'
file '2016_0403_170630_100.MOV'
...

    And I run ffmpeg using next command:

    ffmpeg -f concat -i cf.txt -qscale:v 0 -filter:v "setpts=0.05*PTS" -an e:\MOVIE\all.mov

    After some outputs ffmpeg crushes with message:

    Output #0, mov, to 'e:\MOVIE\all.mov':

  • Use bluetooth headset device as audio source in ffmpeg

    3 avril 2016, par Murat

    I want use a bluetooth headset as audio source for recording a video. I can use arecord -D bluetooth -f s16_le -c1 -r8000 command and pipe audio to ffmpeg. But this cause sync problems in audio and video. so i want to capture audio without arecord. How can i define bluetooth device as audio source in ffmpeg command?

    My asoundrc file:

    pcm.bluetooth {
            type bluetooth
            profile "auto"
        }

 ctl.bluetooth {
   type bluetooth
 }

  • ffmpeg produces video I cannot load on latest Safari on iOS

    3 avril 2016, par Michael Heuberger

    When I encode two videos (mp4 and webm) with these ffmpeg parameters (based on images), I cannot play the mp4 it produces on latest Safari (inside a tag) inside my iPhone 6s using the latest iOS too:

    ffmpeg 
-framerate 15.2 
-f image2 
-thread_queue_size 64 
-i /home/michael-heuberger/abcd/frames/%d.webp 
-y 
-an 
-vcodec libx264 
-vf scale=trunc(iw/2)*2:trunc(ih/2)*2 
-crf 16 
-preset fast 
-profile:v baseline 
-pix_fmt yuv420p 
-movflags +faststart 
/home/michael-heuberger/abcd/videomail_good.mp4 
-vcodec libvpx 
-vf scale=trunc(iw/2)*2:trunc(ih/2)*2 
-crf 8 
-deadline good 
-cpu-used 1 
-pix_fmt yuv420p 
-movflags +faststart /home/michael-heuberger/abcd/videomail_good.webm

    I think the above parameters should be solid. I am adding baseline and yuv420p, yet no luck on Safari 9. Why?

    And here is the whole ffmpeg output (just ignore the paths to the images/videos):

    This makes it difficult for me to play videomails recorded on www.videomail.io on iOS devices.

    Am I missing something here? Already did lots of research and tried various combinations, no luck.

    If you want to reproduce that, easy: just record a video on www.videomail.io and after that, copy the link of the recorded video page to your iPhone or just download it for local investigation.

    Any clues very welcome!

  • FFMPEG Incorrect File Output Path

    3 avril 2016, par Benny Chen

    I'am working in windows 7 32bit and trying to stream file with ffmpeg, but the output file keep going on wrong location.

    If I use this code:

    ffmpeg -i input -c:v copy -c:a copy output.mp4

    The output file will be saved in /Users/{username}

    If I use absolute path:

    ffmpeg -i input -c:v copy -c:a copy c:/output.mp4

    or 

    ffmpeg -i input -c:v copy -c:a copy "c:/output.mp4"

    It put the file in /Users/{username}/AppData/Local/VirtualStore

    So..it is weird and what the heck is the "VirtualStore" folder still a mystery....

    My question is simple, how to put output file in desired path location. Thanks.

  • ffmpeg m3u8 hls to .ts stream

    3 avril 2016, par kekit

    Currently I have a m3u8 live HLS stream, generated by a tvheadend + some custom software running in a linux machine.

    I would also like to create a single .ts http live streaming option, from my m3u8, using the ffmpeg.

    Could someone help me with the command?

    Regards
