ffmpeg(libavcodec). memory leaks in avcodec_encode_video
- by gavlig
I'm trying to transcode a video with help of libavcodec.
On transcoding big video files(hour or more) i get huge memory leaks in avcodec_encode_video. I have tried to debug it, but with different video files different functions produce leaks, i have got a little bit confused about that :). [Here] (http://stackoverflow.com/questions/4201481/ffmpeg-with-qt-memory-leak) is the same issue that i have, but i have no idea how did that person solve it. QtFFmpegwrapper seems to do the same i do(or i missed something).
my method is lower. I took care about aFrame and aPacket outside with av_free and av_free_packet.
int
Videocut::encode(
AVStream *anOutputStream,
AVFrame *aFrame,
AVPacket *aPacket
)
{
AVCodecContext *outputCodec = anOutputStream->codec;
if (!anOutputStream ||
!aFrame ||
!aPacket)
{
return 1;
/* NOTREACHED */
}
uint8_t * buffer = (uint8_t *)malloc(
sizeof(uint8_t) * _DefaultEncodeBufferSize
);
if (NULL == buffer) {
return 2;
/* NOTREACHED */
}
int packetSize = avcodec_encode_video(
outputCodec,
buffer,
_DefaultEncodeBufferSize,
aFrame
);
if (packetSize < 0) {
free(buffer);
return 1;
/* NOTREACHED */
}
aPacket->data = buffer;
aPacket->size = packetSize;
return 0;
}
