Hello,
I'd like to use avformat library to format the h264 stream which I get
from the hardware codec on my SoC to some container (mkv, 3gp, ...). What
parameters need to be set avformat? I have tried following code
(simplified).
AVFormatContext *os;
AVOutputFormat *fmt;
AVStream *video_st;
av_register_all();
fmt = av_guess_format("matroska", NULL, NULL);
os = avformat_alloc_context();
os->oformat = fmt;
strncpy(os->filename, "test.mkv", 32);
video_st = av_new_stream(os, 0);
video_st->codec->codec_id = CODEC_ID_H264;
video_st->codec->codec_type = AVMEDIA_TYPE_VIDEO;
avio_open(&os->pb, "test.mkv", URL_WRONLY);
av_write_header(os);
while (frames) {
AVPacket pkt;
av_init_packet(&pkt);
pkt.data = enc_buf->user_addr;
pkt.size = enc_buf->bytes_used;
pkt.pts = env->frame_cnt;
pkt.stream_index = 0;
av_interleaved_write_frame(os, &pkt);
}
av_write_trailer(os);
Unfortunately this ends with SIGFPE arithmetic exception.
I think I can create a "dummy" avcodec codec and use it to fill the
contents of video_st->codec, but I'd rather to go without such workaround.
Maybe the parameters can be read from the first frame of the raw h264
stream?
with best regards
Jan
