Pre-Transcoding live streams before Re-stream them to wowza Streaming Engine [on hold]

14 décembre 2017, par Ninja
i'am using ffmpeg on other device to get live feed from cam and convert them to multi bitrate outputs localy and stream them to a remote wowza to achieve adaptive bitrate content for users with optimized resources i have succeeded to transcode to one specifique bitrate locally using this line
```
 ffmpeg -re -i cuted.mp4 -c:v libx264 -profile:v baseline -level:v 1.2 -r 12 -g 96 -vb 110000 -s 212x120 -c:a libvo_aacenc -ab 40000 -ar 22050 -ac 1 -f rtsp -muxdelay 0.1 rtsp://*****:*****@***.168.*0.*0:1935/live/myStream
```
but i need at least 4 resolutions support i've tried to lunched twice at the same time with diffrent resolutions but in wowza engine manager => incoming streams i got one stream input, i appreciate any suggestion

FFMPEG audio and video frames not maching each others ?

14 décembre 2017, par Gomi Odabaşıoğlu

I am trying to use FFMPEG console tools effectively. Now I can record video and audio same time but my issue audio is delaying. I use following code:

C:\Users\gomid_000\Desktop\ffmpeg.exe -y -f dshow -i audio="Stereo Mix (Realtek High Definition Audio)" -f gdigrab -show_region 1 -framerate 60 -i desktop -map 0 -map 1 -c:v libx264 -preset ultrafast -pix_fmt yuv420p C:\Users\gomid_000\Desktop\out.mp4 -threads:1 4

Update : Frames were duplicating, indeed it was not ready for intel qsv, I use h264 now. I updated it like this following code delay is fixed a bit but frame performance is reduced now I need options to reduce performance drop also:

C:\Users\gomid_000\Desktop\ffmpeg.exe -y -f dshow -i audio="Stereo Mix (Realtek High Definition Audio)" -c:a aac -f gdigrab -draw_mouse 1 -i desktop -c:v libx264 -qp 0 -pix_fmt yuv444p -preset ultrafast -tune zerolatency -crf 0 -maxrate 1M -bufsize 2M -vf mpdecimate -r 15 -threads:4 4 "C:\Users\gomid_000\Desktop\recording-$(get-date -f yyyy-MM-dd-Hmss).mp4"

What should I do to use aac and h264_qsv codec together ?
Which improvments can I do to prevend audio or video delay ?

Android YouTube Live v3 rtmp streaming via ffmpeg won't show preview

14 décembre 2017, par Ariel Yust

Hi everyone I'm breaking my head over this issue here, I'm developing an Android App for streaming content from the user's device camera (back/front) to a live streaming on YouTube.

Problem: YouTube Live shows "The health is good." in (Live Streaming->Events) but there's nothing showing in the preview... in fact when I press play it tells me "An error has occurred, please try again later".

Why is this happening ? what could be the problem ?

What I'm doing: using google's Oauth 2.0 and google api for login. YouTube V3 data api's for creating a new broadcast and stream or use an opened stream - I'm using RTMP.

I'm opening Camera Api1 and capturing the video into a SurfaceTexture, then I encode images and audio (MIC) using Android's MediaCodec, save a 3+- seconds *.mp4 file locally and then once the muxer is done I stream the file with ffpmeg.

String[] cmd = {
            "-i", filePath, //local file path (video is playable with vlc)
            "-strict", "experimental",
            "-acodec", "aac",
            "-ac", "1",
            "-ar", "44100",
            "-vcodec", "libx264",
            "-pix_fmt", "yuv420p",
            "-r", "30",
            "-g", "60",
            "-vb", "512k",
            "-profile:v", "main",
            "-preset", "medium",
            "-f", "flv",
            "-s", "1280x720",
            CreateBroadcast.rtmpUrl
        };

ffmpeg.execute(cmd, responseHandler); //responseHandler notify me to send next file

//how I set a new rtmpUrl, in CreateBroadcast.java
rtmpUrl = 
    returnedStream.getCdn().getIngestionInfo().getIngestionAddress() +
    File.separator + 
    returnedStream.getCdn().getIngestionInfo().getStreamName();

next file

Using this ffmpeg library.
