• Mpeg2-TS bad output and pixelation from FFmpeg on Android

  8 décembre 2020, par henry

  I am using the FFmpeg extension for Exoplayer to play mpeg2ts video on a mobile device.
The device doesn't have a hardware codec for mpeg2ts video. So I want to use SW codec with FFmpeg.
But the output frames were broken, bad pixelation.
See the captured frame below.


  


  But when I ran the same application on an Aosp device, the video frame was correct.

  


  Does anyone have an idea why the output on mobile was broken ?
Actually, I don't have any background in FFmpeg and mpeg2ts media format.
And I just got this source from an Exoplayer distributor who is not available anymore.

  


  I added ffmpeg_jni file
ffmpeg_jni.cpp

  


• Android jni x264_encoder_encode Out of memory error

  25 octobre 2020, par Stanley Wintergreen

  I am using a library x264 to encode a video stream from a camera into a codec h264. I follow examples like : 1, 2, 3. I am receiving data from a camera using Camera.setPreviewCallbackWithBuffer.

  


  During the call of the method x264_encoder_encode, memory is allocated inside the JNI that is not released and after a while I get an out of memory error. I wrote this JNI. The following code is enough to reproduce the problem :

  


  JNIEXPORT jbyteArray JNICALL Java_org_videolan_x264_x264JNI_encode(
    JNIEnv *env,
    jclass cls,
    jlong encoder_context_pointer,
    jbyteArray decoded,
    jlong time
) {
    EncoderContext* encoder_context = (EncoderContext*) encoder_context_pointer;
    x264_nal_t* pp_nal;
    int pi_nal;
    x264_picture_t picture_out;
    int frame_size = x264_encoder_encode(
            encoder_context->x264_encoder,
            &pp_nal,
            &pi_nal,
            &encoder_context->picture_in,
            &picture_out
    );
    return NULL;
}


  


  It seems to me that I take into account everything that is recommended in the examples, but apparently this is not so. I also believe that the method works because I receive an array with the expected data in response.

  


• Record ip camera streaming with two login authentication

  13 octobre 2020, par oxorio

  I'm trying to record a stream with ffmpeg, VLC or OBS that before you view the stream player you need to login with a microsoft account, the URL is something like this

  


  https://yourwebsite.msappproxy.net/Camera/player.html?stats=1


  


  And after you login you have to insert a username and password to watch the camera you want to see.

  


  I've got the .m3u8 and tried to play it on VLC but doesn't start the streaming, searching i found that you can add the credentials to the stream link but this doesn't work either

  


  https://user:password@yourwebstite.msappproxy.net/Camera/hls/live.stream.m3u8


  


  I also tried with the extension "Video DownloadHelper" on Firefox and this extension is able to download the stream but at somepoint stops the download and you need to relogin on the website

  


  Edit :
Added the VLC output log

  


  -- logger module started --
main: Running vlc with the default interface. Use 'cvlc' to use vlc without interface.
main: playlist is empty
-- logger module stopped --


  


  I tried with "Open in VLC" extension on Firefox so you can open the link you want to play on VLC.

  


  The URL that capture this extension is like this

  


      https://yourwebsite.msappproxy.net/Camara/hls/live.stream-152121.ts


  


  And the VLC output log

  


  -- logger module started --
main: Running vlc with the default interface. Use 'cvlc' to use vlc without interface.
ps warning: this does not look like an MPEG PS stream, continuing anyway
ps warning: garbage at input from 509, trying to resync...

  Edit 2 (Solution) :
I solved the problem using this chrome extension

  


  Stream Recorder Chrome

  


  Using this extension I was able to capture the stream without cuts
