av_video_decode2 RETURNS THE VALUE -1094995529 in the threaded function
24 mai 2014, par WhoamiI am developing rtsp streaming player, and followed the below approach.
1) Read packet, decode, display -> works perfectly.
while (1) {
if ( av_read_frame(pFormatCtx, &packet) >= 0) {
if (packet.stream_index == videoStream) {
retDecoder = avcodec_decode_video2(pCodecCtx, pFrame, &frameFinished, &packet);
if ( retDecoder <= 0)
LOGD (" Unable to Decode...retval %d ", retDecoder);
if (frameFinished) {
}
}
av_free_packet (&packet);
}
}Whereas,
I introduced two threads, one is reading and pushing into the queue and the second one is reading from the queue.
My problem is while reading the same packet, and decode, i m unable to decode, the return value of the
