QMediaPlayer cannot help you? QMediaPlayer can decode video files.

@HeresJonny and @SGaist , Did you finally find a solution for this problem ?

[SGaist]

The links provided by @andreyc are a good starting point.

@SGaist i am receiving raw h264 frames from a QTCP socket, i need a function or library where i will pass the h264 data (QByteArray) from a http payload, and decode it to pass it to a video player. The QT Multimedia library doesn't work with encoded data. i already tried using the QTAV library but there's is no luck in Reaching what i need. Please help.

[SGaist]

What OS are you targeting ?

[Bongani]

@SGaist Windows, Preferably 7 to 10.

[SGaist]

Do you have any h264 codec installed ?

[Bongani]

@SGaist Yes, unfortunately VLC-QT from https://vlc-qt.tano.si doesn't support the particular functionality i require. i also tried using the QTAV library from http://www.qtav.org, which uses the ffmpeg library. none of these are of help because they don't support raw h264 bit streaming. you can check my conversation with on of the repository admins here https://github.com/wang-bin/QtAV/issues/510. I was wondering if QT has a library i could pass my QByteArray data (raw h264 data) from a QTCPSocket and decodes the bit-stream and stream it live.

Are you sure that FFMPEG doesn't help ? See this

@SGaist

AVPacket avpkt; int err, frame_decoded = 0;
AVCodec *codec = avcodec_find_decoder ( AV_CODEC_ID_H264 );
AVCodecContext *codecCtx = avcodec_alloc_context3 ( codec );
avcodec_open2 ( codecCtx, codec, NULL );
// Set avpkt data and size here
err = avcodec_decode_video2 ( codecCtx, avframe, &frame_decoded, &avpkt );

avframe being the QByteArray data from the socket ?

[SGaist]

You'll likely have build your avframe with the data contained by the QByteArray
