Re: [Libav-user] global headers problem when encoding/decoding h264
2012/4/19 Matthias Bühlmann gene...@gmx.ch: I'm developing in MSVC++ and use precompiled libraries and thus would like to avoid having to alter the FFMPEG code. Is there any other way how I can either get the global headers into my decoder, so that it can decode the packets on the fly without the need of headers in every packet, or to tell the encoder to add the headers to each frame AND to use global headers? Hard to say without your code. How do you init the decoding contexts? BTW, consider publishing here simplified working source code of your app, especially good if it compiles with gcc and run on linux, coz majority of developers here use it. If i had to do such a thing, i'd go with somewhat overheady, but surely working way: Initiate _two_ output stream contexts, one for desired output destination, and second for testing. Also open one input stream context, for reading the test output. Let test stream be bound to localhost tcp socket, for example. When you have the AVPacket, go muxing it into both outputs. Then, read the test stream, and display the resulting picture after decode. -- Andrey Utkin ___ Libav-user mailing list Libav-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/libav-user

Carl Eugen How can I tell if it is unencrypted and unencrypt it? Is audio decoding possible? If the DVD is encrypted, FFmpeg is not the right tool (currently, a patch is being reviewed), mplayer -dumpstream outputs the unencrypted DVD.

[Libav-user] avcodec_encode_video returns 0 or -ve value
Hello Everyone, I want to encode series of uiimages which are being captured live by the camera. While encoding the images avcodec_encode_video is returning 0 or -ve value. I am not getting what is the problem. I might be missing setting some parameters of avcodec context or avframe. I want to know which parameters should we set before using avcodec_encode_video. Please help me..Any help is appreciated. ___ Libav-user mailing list Libav-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/libav-user
