• Play AAC in SoundManager2 won't start

  27 novembre 2012, par sasa

  I converted audio file MP4 to AAC and then want to play that file in SoundManager2. If I use some software for Windows for convert, everying is fine, audio is playing well. But, on server side when MP4 file is converted to AAC using ffmpeg, file is loaded in SM2, but playing is not started.

  I use this command :

  ffmpeg -i in.mp4 out.aac

  Here is SoundManager2 log :

  What can be a problem ?

• Live stream failed on Youtube

  20 septembre 2023, par kuldeep chopra

  We are currently running an AWS container that utilizes FFmpeg for live streaming while concurrently saving the stream as an MP4 file. However, we encountered an issue during a recent live stream session that was functioning correctly until approximately 13 minutes in, at which point FFmpeg reported the following error logs :

  


  ffmpeg [flv @ 0x555c4bdfe680] Failed to update header with correct duration.
2023-09-07T23:06:38.490+05:30 [flv @ 0x555c4bdfe680] Failed to update header with correct filesize.
2023-09-07T23:06:38.491+05:30 failed => rtmp://a.rtmp.youtube.com/live2/key......
2023-09-07T23:06:38.491+05:30 ffmpeg [tee @ 0x555c48843700] Slave muxer #1 failed: Broken pipe, continuing with 1/2 slaves.


  


  It's worth noting that we have conducted hundreds of live streams on YouTube without encountering this error before ; this is the first occurrence of such an issue.

  


  We would greatly appreciate it if you could investigate and provide insights into the underlying problem causing these error messages.

  


• Android Video Compression [on hold]

  10 mars 2015, par Arif Gencosmanoglu

  I am planning to build a small Android JAVA application that compresses images and videos. I did the image compression part and my .apk size is 1.5MB. However when I do the video compression part by using ffmpeg the application size goes up to 20.0MB. This library has tons of features that I am not using. I only need a simple video compression module to add.

  Is there any other video compression methods or functions that will be useful ?

  Thanks.
