• HLS and ffmpeg - losing audio ?

  12 octobre 2015, par Stefan Kendall

  With the following command, I only get video. The same setup with -f segment gets video and audio, but then the resulting stream doesn’t play on an iPhone.

  How do I get ffmpeg to encode video and audio into the HLS segments ?

  ffmpeg -v 9 -loglevel error -re -i rtmp://localhost/live/test \
  
  -c:v libx264 -c:a copy \
  
  -flags -global_header -map 0 -f hls \
  
  -hls_list_size 10 \
  
  -hls_flags delete_segments /usr/local/nginx-streaming/html/video/stream.m3u8 

• avcodec_decode_audio4 decoded data different on device and simulator

  5 décembre 2013, par Jona

  I'm having issues where the decoded audio sounds punchy/garbled simply can't tell what is being heard when decoded on an iPhone/iPad device. However, when decoding the audio on simulator the audio is perfect.

  I do realize emulator runs on a different CPU architecture i386 while actual device is ARMv7 so the issue could be something around that.

  I have printed the compressed data on device and simulator before being decoded and it matches. Then I printed the decoded data for device and simulator and they are different. That leads me to think something is happening with the decoder. I can see that it is not a byte swap issue since the data is just completely different.

  Any ideas on what I could or look into ? I don't have this issue on Android...

  First decoded audio frame.

  DEVICE :

  0x00, 0x00, 0xff, 0xff, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x70, 0x08, 0x00, 0x00, 0x00, 0x00, 0x03, 0x00, 0xda, 0x0a, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,

  EMULATOR :

  0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,

  UPDATE 1
  I was able to resolve the issue by disabling asm with --disable-asm. Something must not be working correctly with the ARM asm files.
