'pjsip-apps/Samples' Cannot functionally run vid_streamutil.c sample
2 décembre 2020, par ShootingKIngIssue 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 :


- 

- 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

How To Write An Oscilloscope
I’m trying to figure out how to write a software oscilloscope audio visualization. It’s made more frustrating by the knowledge that I am certain that I have accomplished this task before.
In this context, the oscilloscope is used to draw the time-domain samples of an audio wave form. I have written such a plugin as part of the xine project. However, for that project, I didn’t have to write the full playback pipeline— my plugin was just handed some PCM data and drew some graphical data in response. Now I’m trying to write the entire engine in a standalone program and I’m wondering how to get it just right.
This is an SDL-based oscilloscope visualizer and audio player for Game Music Emu library. My approach is to have an audio buffer that holds a second of audio (44100 stereo 16-bit samples). The player updates the visualization at 30 frames per second. The o-scope is 512 pixels wide. So, at every 1/30th second interval, the player dips into the audio buffer at position ((frame_number % 30) * 44100 / 30) and takes the first 512 stereo frames for plotting on the graph.
It seems to be working okay, I guess. The only problem is that the A/V sync seems to be slightly misaligned. I am just wondering if this is the correct approach. Perhaps the player should be performing some slightly more complicated calculation over those (44100/30) audio frames during each update in order to obtain a more accurate graph ? I described my process to an electrical engineer friend of mine and he insisted that I needed to apply something called hysteresis to the output or I would never get accurate A/V sync in this scenario.
Further, I know that some schools of thought on these matters require that the dots in those graphs be connected, that the scattered points simply won’t do. I guess it’s a stylistic choice.
Still, I think I have a reasonable, workable approach here. I might just be starting the visualization 1/30th of a second too late.

G.I. Joe Custom Multimedia
30 mars 2012, par Multimedia Mike — GeneralI received this 3-disc set of G.I. Joe CD-ROMs today :
Copyright 2003, and labeled as PC ONLY. Each disc claims to have 2 episodes. So are these some sort of video discs ? Any gaming elements ? I dove in to investigate.
So, it turns out that there are some games on these discs, done in Flash Player (which tells me that these were probably available on the web at some point). Here’s a shooting gallery game from the first disc :
As promised by the CD-ROM copy, the menu does grant access to 2 classic G.I. Joe episodes. Selecting either one launches this :
Powered by C-ezy ? Am I interpreting that correctly ? Anyway, the video player goes fullscreen and looks fine (given the source material). I can’t capture screenshots and controls are limited to : space for pause, ESC to exit player, and up/down to control volume. No seeking and certainly no onscreen controls. Pretty awful player.
Studying the first disc, I find a 550 MB file with the name 5859Hasbro.egm. Coupled with ep58.cfg and ep59.cfg files in the same directory, I gather that the disc has G.I. Joe episodes 58 and 59 (though the exact episodes, “There’s No Place Like Springfield” parts 1 and 2, are listed on Wikipedia as being episodes 154 and 155 ; but who’s counting ?). The cfg files contain this text :
ep58.cfg : EGM_GIJOE.exe 5859Hasbro.egm /noend /track:0 /singletrack
ep59.cfg :
EGM_GIJOE.exe
5859Hasbro.egm /noend /track:1 /singletrackThe big EGM file starts with the string “Egenie Player”. After that, I see absolutely no clues. The supporting EGM_GIJOE.exe file has some interesting strings : “Decore Bits Per Pixel” (I know I have seen “Decore” used to mean “decoding core” in some libraries), “Egenie Player – %s, Version :%s”, “4th June 2002″, a list of common FourCC tags seen in AVI files, “Brought to you by Martin, Patrick Bob and Bren” (do you suppose “Patrick Bob” is one person’s name ?), a list of command line options…
Aha ! A URL : http:\www.e-genie.tv (yep, backslashes, not forward slashes). e-genie.tv seems to redirect to mygenie.tv, which… doesn’t appear to be strictly related to video technology these days.
