Hi guys,
I know if I call av_new_packet then the data buffer created will
be padded and aligned.
But how if I only use ffmpeg to do the muxing?
Say if I get a buffer with size n. My code looks like this.
AVPacket pkt;
ZeroMemory(&pkt, sizeof(pkt));
pkt.stream_index = myindex;
pkt.pts = myPTS;
pkt.data = myPtr; (points to a buffer allocated in my program)
pkt.size = mySize;
av_write_frame(pFormatCtx, &pkt)
Is above code OK? or do I need to allocate pkt.data with padding +
alignment and copy my data into it?
Thanks
Hi, Can anyone help on this?
Thanks
AFAIK, you need to allocate with alignment taken into account. av_malloc
(in libavutil/mem.h) and similar should be of help.
