Dear All
i am decoding video frames using ffmpeg library in java, but if i want
to decode multiple video at a time then decoding time is increasing.
1. i tried example given in ffmpeg hw_decode.c and converted to java but
hardware acceleration not supporting
2. Able to call av_hwdevice_ctx_create intializing properly
3. recpack=av_read_frame(fmt_ctx, pkt);
// if(recpack<=0)
// break;
if (pkt.stream_index() == v_stream_idx) {
ret1 = avcodec_send_packet(codec_ctx, pkt);
ret2 = avcodec_receive_frame(codec_ctx, frm);
no error even able to print format and width and height from frm
variable.
if ((ret = av_hwframe_transfer_data(frm, tmp_frm, 0)) < 0)
Above function also i am checking but when i try to display it gives
black image
Or i am happy to know any other method to decode multiple file at a time .
Best Regards
Satish
