FFmpeg av_read_frame returns packets from audio stream
1er août 2018, par yultanI am currently trying to learn the FFmpeg API, following this tutorial. However, I already have issues with the first lesson on video decoding. My code is basically the same as the one from the tutorial except I am using C++. My issue is that the video stream does not match the one from the packet returned by
av_read_frame
.The video stream is obtained looping on the available streams until the video stream is found.
for(int i = 0; i < pFormatCtx->nb_streams; i++) { // nb_streams == 2
if(pFormatCtx->streams[i]->codec->codec_type==AVMEDIA_TYPE_VIDEO) {
videoStream = i;
break; // videoStream == 0
}
}Then when retrieving the frame data, it seams grabbing the audio channel.
while(av_read_frame(pFormatCtx, &packet) >= 0) { // read returns 0
// Is this a packet from the video stream?
if(packet.stream_index == videoStream) {
//packet.stream_index == 1, which correspond to the audio stream
}
}I have not found examples online where this test is actually failing. Have I miss some way to specify the
stream_index
that is not in the tutorial ? Maybe the tutorial is not up to date and is doing something wrong ? If so, what is the correct way to extract the frame data ? In case that matters, I am using the latest FFmpeg 4.0.2 build, on Windows 64-bits, compiling with Visual Studio 2017.On videos with no sound, the two streams match and I am able to decode and display the frames correctly.
