Hello all.
I am working on a capture/encoder project. I've gotten it to work well
enough, for the most part.
If I record shorter segments, like in the 1-2 minute range, the output
files are fine.
However, as the clip gets longer, it eventually starts hitting an I/O
Error (-5) when executing *av_interleaved_write_frame(format_context,
output_packet). *It never recovers from this, all writing to the file
stops, and attempting to close the file results in an unplayable file.
This is the part of the code that writes audio frames, and also where
the error is detected:
int Recorder::audioWriteFrame(void* ctx, AVFrame* frame) {
if (!decoding) return -1;
if (recording) {
frames_all++;
frames_audio++;
AVPacket* output_packet = av_packet_alloc();
int ret = avcodec_send_frame(audio_context, frame);
while (ret >= 0)
{
ret = avcodec_receive_packet(audio_context, output_packet);
if (ret == AVERROR(EAGAIN) || ret == AVERROR_EOF) {
break;
}
else if (ret < 0) {
cout << "AUD-AVCRPX: ";
cout << ret;
break;
}
chrono::steady_clock::time_point now =
chrono::high_resolution_clock::now();
long long ms_elapsed =
chrono::duration_cast<chrono::microseconds>(now - rec_started).count();
ms_elapsed = av_rescale_q(ms_elapsed,
audio_context->time_base, audio_stream->time_base);
output_packet->pts = ms_elapsed;
output_packet->dts = ms_elapsed;
output_packet->stream_index = audio_stream->index;
* ret = av_interleaved_write_frame(format_context,
output_packet); **
** if (ret < 0) {**
** char* errmsg = new char[4096];**
** av_strerror(ret, errmsg, 4096);**
** cout << "audio av_interleaved_write_frame ERROR: ";**
** cout << errmsg;**
** cout << "\r\n";**
** }**
** ret = ret;*
}
av_packet_unref(output_packet);
av_packet_free(&output_packet);
}
return 0;
}
Any ideas why this is happening would be helpful.
