Thanks Stefano, for your suggest. I never used av_log then I looked around.
I implemented the follow avlog callback, to log info into file.
--------
static void ffmpeg_avcodec_log(void *ptr, int val, const char * msg, va_list
ap)
{
AVClass* avc= ptr ? *(AVClass**)ptr : NULL;
FILE *flog=fopen("MMedia.log","a");
fprintf(flog, "[%s @ %p] ", avc->item_name(ptr), avc);
vfprintf(flog, msg, ap);
fclose(flog);
}
---------
And the new code is this:
---------
int CFFDecode::Init(int codec_id, int width, int height, int fps)
{
if ((width & 1) == 1) return E_INVALIDARG;
if ((height & 1) == 1) return E_INVALIDARG;
av_log_set_callback( ffmpeg_avcodec_log );
m_codec = avcodec_find_decoder((CodecID)codec_id);
if (m_codec == NULL) {DbgOut("FFINIT OK");return E_FAIL;}
m_c = avcodec_alloc_context();
if (m_c == NULL)
{DbgOut("avcodec_alloc_context error");return
E_OUTOFMEMORY;}
avcodec_get_context_defaults2(m_c, CODEC_TYPE_VIDEO);
avcodec_get_frame_defaults(&m_picture);
m_c->codec_id = (CodecID) codec_id;
m_c->codec_type = CODEC_TYPE_VIDEO;
m_c->strict_std_compliance = 0;
m_c->width = width;
m_c->height = height;
m_c->time_base.den = fps;
m_c->time_base.num = 1;
m_c->gop_size = 12;
m_c->pix_fmt = PIX_FMT_BGR24;
/* open the codec */
int iRetOpen = avcodec_open(m_c, m_codec);
if ( iRetOpen < 0) {
av_log(m_c, AV_LOG_DEBUG, "Fail avcodec_open\n");
return E_FAIL;
}
--------------
Into log file I've only this information!
[NULL @ 68C432E0] Fail avcodec_open
I can't undertand where is the problem
thanks
Stefano Falasca
