4 bytes in 1 blocks are definitely lost in loss record 1 of 6
in muxing(char const*) in main.cpp:275
1: malloc in
/tmp/buildd/valgrind-3.6.0~svn11254+nmu1/coregrind/m_replacemalloc/vg_replace_malloc.c:236
2: realloc in
/tmp/buildd/valgrind-3.6.0~svn11254+nmu1/coregrind/m_replacemalloc/vg_replace_malloc.c:525
3: avformat_new_stream in <a
href="file:///home/denis/C++/ffmpeg-1.0/libavformat/utils.c:3138"
>/home/denis/C++/ffmpeg-1.0/libavformat/utils.c:3138</a>
4: muxing(char const*) in <a
href="file:///home/denis/C++/QtFFmpeg/QtFFmpegEncoder/C/C-build-desktop/../C/main.cpp:275"
>main.cpp:275</a>
5: main in <a
href="file:///home/denis/C++/QtFFmpeg/QtFFmpegEncoder/C/C-build-desktop/../C/main.cpp:324"
>main.cpp:324</a>
The row 275 is below:
pAVStream= add_video_stream(pAVFormatContext, &pAVCodec,
pAVOutputFormat->video_codec);
that has the correspondent row
close_video(pAVFormatContext, pAVStream);
for (int count= 0; count< pAVFormatContext->nb_streams; count++) {
av_freep(&pAVFormatContext->streams[count]->codec);
av_freep(&pAVFormatContext->streams[count]);
}
if (!(pAVOutputFormat->flags &
AVFMT_NOFILE))avio_close(pAVFormatContext->pb);
//av_free(pAVFormatContext);
avformat_free_context(pAVFormatContext);
but valgrind says detects memory leak.
