  • Adobe Air , NativeProcess and ffmpeg

    18 août 2013, par Tom Lecoz

    First of all, please excuse me if my english is not perfect, I hope you could understand me...

    I discover yesterday this video tutorial about Air Native Process and FFMPEG, it shows how to create an Air app that can read every video format (avi, mkv, ...).

    http://www.youtube.com/watch?v=6N7eN9wvAGQ

    I tryed to reproduce it but obviously it didn't work...

    Then I looked for an example of it, with working source code, on the internet. I found this

    http://suzhiyam.wordpress.com/2011/05/05/as3ffmpeg-play-multi-video-formats-in-air/

    The author said it's a document class for a Flash project, it just need a button component, a text area and a video Object.

    I tryed it inside a Flash project, it didn't work...
    So, I made some adjusment to run it outside Flash (I just replaced the DisplayObject on the stage by ActionScript code), just because it easier if you want to test it.

    When I say "it didn't work", I mean my video is not read at all. The nativeProcess is working, my executable is recognize but I always get some ProgressEvent.STANDARD_ERROR_DATA and then the process stop...

    I'm working on Windows 7 64 bit.
    I tryed with FFMPEG 32 & 64 bit and get the exact same (no) result.

    You can find my code here

    Can someone help me ?

    Please ! :)

    Thanks by advance !

  • How to create a script on a Raspberry to run ffmpeg at boot and restart itself if/when ffmpeg fails ?

    5 février 2021, par Mycelium

    I'm using a Raspberry Pi Zero to stream to YouTube using FFMPEG. It works great so far and now I'd like to set it up to run the stream/FFMPEG daily and automatically from 6am to 7pm and restart itself in case it fails.

    


    I've heard/read of people doing so with Python, but I haven't been able to find examples to try. I've never used Python (or any other) before, I'm a complete beginner. All I know is how/where to place the script file to make it run at boot.

    


    Could anyone point me in the right direction on how to achieve this ? The FFMPEG command is as follows :

    


    v4l2-ctl --set-fmt-video=width=1280,height=720,pixelformat=4 
v4l2-ctl --set-ctrl=rotate=180
v4l2-ctl --overlay=1
v4l2-ctl -p 30
v4l2-ctl --set-ctrl=video_bitrate=2000000
ffmpeg -ar 44100 -ac 2 -acodec pcm_s16le -f s16le -i /dev/zero -f h264 -framerate 30 -i /dev/video0 -vcodec copy -acodec aac -ab 128k -g 60 -f flv -r 30 rtmp://a.rtmp.youtube.com/live2/SECRET-KEY


    


  • ffmpeg to split mp4 file into segments... after first segment, audio unsynced

    13 avril 2015, par bcsteeve

    I’ve used the ffmpeg command line shown in this question to split MKV files perfectly for a long time. Now i have some MP4 files that i’d like to split and at first it seemed to work, but every subsequent segment after the first has the audio not synced ! And by several seconds.

    I’ve tried forcing keyframes (advice I found on some other sites) and that didn’t help.

    I tried a different program entirely (Avidemux) and it was able to split the file with proper output, but it was a LOT slower, taking upwards of 3 minutes vs less than 2 seconds with ffmpeg. With Avidemux I was able to determine the exact position of the i-frame where I wanted to split, so thinking perhaps that was the syncing problem I tried that exact position (ie. 00:12:17.111 instead of 00:12:16 or whatever) but that didn’t help either.

    Is there an option I’m missing with ffmpeg to get it to properly sync audio to the video when splitting ?
