• aacenc_pred : rework the way prediction is done

  29 août 2015, par Rostislav Pehlivanov

  aacenc_pred : rework the way prediction is done
  This commit completely alters the algorithm of prediction.
  
  The original commit which introduced prediction was completely
  
  incorrect to even remotely care about what the actual coefficients
  
  contain or whether any options were enabled. Not my actual fault.
  This commit treats prediction the way the decoder does and expects
  
  to do : like lossy encryption. Everything related to prediction now
  
  happens at the very end but just before quantization and encoding
  
  of coefficients. On the decoder side, prediction happens before
  
  anything has had a chance to even access the coefficients.
  Also the original implementation had problems because it actually
  
  touched the band_type of special bands which already had their
  
  scalefactor indices marked and it’s a wonder the asserion wasn’t
  
  triggered when transmitting those.
  Overall, this now drastically increases audio quality and you should
  
  think about enabling it if you don’t plan on playing anything encoded
  
  on really old low power ultra-embedded devices since they might not
  
  support decoding of prediction or AAC-Main. Though the specifications
  
  were written ages ago and as times change so do the FLOPS.

• 'pjsip-apps/Samples' Cannot functionally run vid_streamutil.c sample

  2 décembre 2020, par ShootingKIng

  Issue Description
After building[Build Varient=Debug, Build Config=x64] the latest pjproject-vs14 (retargeted to MSVS 2017, WINSDK=8.1, because my application works at these config) as per the build instruction on trac website. Successfully built pjsua and samples.

  


  I want to use only RTP + FFMPEG APIs (pjmedia) for my application from pjproject.

  


  My config_site.h

  


  #define PJMEDIA_HAS_VIDEO           1
#define PJMEDIA_HAS_FFMPEG          1


  


  FFMPEG (pre build from ffmpeg-N-100121-g052b4c3481-win64-gpl-shared.zip)

  


  But running the example, vid_streamutil.c did not work as expected (? Whats the normal expected behaviour ?).
It says

  


  ffmpeg_vid_cod  ffmpeg err -22: Invalid argument
vstenc0000016B  Codec encode_begin() error: Codec internal creation error (PJMEDIA_CODEC_EFAILED)


  


  To Reproduce
Steps to reproduce the behavior :

  


  

  1. run vid_streamutil.exe with parameter : --codec=H264 --remote=127.0.0.1:5000 --play-file=test.avi --send-only
(test.avi file being a sample file)

  


  


  Expected behavior
Get some RTP packets in wireshark while listening to ports 4000 and 5000 maybe ? I dont know whats the expected behaviour, documentation dosent say anything about this :(

  


  Logs/Screenshots
Couldn't catch anything on Wireshark.
Console log of vid_streamutil.exe is

  


  vid_streamutil.exe --codec=H264 --remote=127.0.0.1:5000 --send-only --play-file=test.avi

  Additional context
I didnt change the default program that must except adding some printf's when program goes to exit label, without this it will be very difficult to know which part of the program jumped to exit : label. Anyways, here is the full code,

  


  vid_streamutil.c (with printfs)

  


  Any help is appreciated ^^'
Thanks.
