I downloaded the latest win32 build and tried to write to a webm file with this
example:
http://libav.org/doxygen/master/libavformat_2output-example_8c-example.html
It fails when trying to open the audio codec
static void open_audio(AVFormatContext *oc, AVStream *st)
{
AVCodecContext *c;
c = st->codec;
/* open it */
if (avcodec_open2(c, NULL, NULL) < 0) { <<<<<< fails here
fprintf(stderr, "could not open codec\n");
exit(1);
}
The codec seems to be set up OK for libvorbis.
codec = 0x6a693460 {name=0x6a6fd67b "libvorbis" long_name=0x6a6fd685 "libvorbis
Vorbis" type=AVMEDIA_TYPE_AUDIO ...}
AVI files work fine. MP4 files output without errors but have bad data. Is
there a better example than output_example.c? Do I have to do more to setup
the codecs than is shown in output_example.c?
Thanks._______________________________________________
