• ffmpeg dshow command is listing device name different from actual device name

  20 octobre 2015, par Somanshu

  i have used the command:ffmpeg -f dshow -list_devices true -i dummy
  to list the devices.
  But if device name is in language other than english then device name shown by ffmpeg and actual differ.

  How can i solve this mismatch problem.

  This image shows the device name in spanish

  This image shows the device name as read by ffmpeg

• FFmpeg encoding live audio to aac issue

  12 juillet 2015, par Ruurd Adema

  I’m trying to encode live raw audio coming from a Blackmagic Decklink input card to a mov file with AAC encoding.

  The issue is that the audio sounds distorted and plays to fast.

  I created the software based on a couple of examples/tutorials including the Dranger tutorial and examples on Github (and of course the examples in the FFmpeg codebase).

  Honestly, at this moment I don’t exactly know what the cause of the problem is. I’m thinking about PTS/DTS values or a timebase mismatch (because of the too fast playout), I tried a lot of things, including working with an av_audio_fifo.

  • When outputting to the mov file with the AV_CODEC_ID_PCM_S16LE codec, everything works well
  • When outputting to the mov file with the AV_CODEC_ID_AAC codec, the problems occur
  • When writing RAW audio VLC media info shows :
    Type : Audio, Codec : PCM S16 LE (sowt), Language : English, Channels : Stereo, Sample rate : 48000 Hz, Bits per sample.
  • When writing with AAC codec VLC media info shows :
    Type : Audio, Codec : MPEG AAC Audio (mp4a), Language : English, Channels : Stereo, Sample rate : 48000 Hz.

  Any idea(s) of what’s causing the problems ?

• How to embed subtitles to .mp4 movie using ffmpeg

  25 novembre 2016, par hudac

  I’m trying to embed subtitles I wrote to a movie I created.
  I’m using FFmpeg version : ffmpeg-20150418-git-edbb9b5-win64-static with the command :
  ffmpeg -i in.mp4 -f srt -i subs.srt -c:v copy -c:a copy -c:s mov_text out.mp4 I saw here.

  But I get errors during the process, and when the process is done there’s an output file out.mp4 without subtitles embedded.
  When I play the in.mp4 in some player such as media player classic with the subtitles separately, the subtitles are sync and everything is fine.

  The subtitles are subrip encoded in UTF8.

  I tried to look out for these errors but didn’t find anything useful. it seems something ridiculous.
  What am I doing wrong ?

  Errors such as :

  [mp4 @ 00000000003fe020] Codec for stream 0 does not use global headers but container format requires global headers
  
  [mp4 @ 00000000003fe020] Codec for stream 1 does not use global headers but container format requires global headers
  
  [mp4 @ 00000000003fe020] Application provided duration: -8 / timestamp: 72205 is out of range for mov/mp4 format
