Question - What is the format in which audio / video ES data is stored in
(AVPacket*) pkt->data? I am trying to demux and decode AV data from a MP4 file
using libavformat and libavcodec.
More details
1. Using the sample application demuxing.c
(http://www.ffmpeg.org/doxygen/trunk/demuxing_8c_source.html) I tried demuxing
and decoding a MP4 file containing H.264 video and AAC audio.
2. While the sample application worked fine, I wasn't able to interpret
the content in the pkt.data buffer (line #66 in the above file). Since the
video was H.264 I was hoping to see familiar "nal_unit_type" but I don't think
I saw that for the stream I was trying to decode. If I remember the data
correctly the first 4 bytes in the pkt.data buffer were "0x00 0x00 0x02 0x72"
I haven't spent much time figuring this out yet but searching on the Internet /
forum didn't help. I intend to dig deeper tomorrow, but just wanted to check if
indeed ES was being passed in the pkt.data buffers in a special way.
Appreciate any points that you can provide.
Best regards
Arvind
