Playing a music on speaker,record it with ffmpeg and save as
music.mp3in current directory.

device_speaker="alsa_output.pci-0000_09_00.6.analog-stereo.monitor"
ffmpeg -f pulse -i $device_speaker music.mp3


I turn off the speaker and play the music on my headphone,how can record it with ffmpeg ?

regarding h264_qsv encoding speed in ffmpeg
31 janvier 2021, par TONYAs we know, now ffmpeg supports intel hardware encoding(h264 qsv).
But it doesn't support "ultra fast", is there any settings to improve the encoding speed ?


m_encoder = avcodec_find_encoder_by_name("h264_qsv");
if(m_encoder == nullptr){
 LOG(ERROR)<<"Find H264 Encoder failed";
 return false;
}
m_ctx = avcodec_alloc_context3(m_encoder);
m_ctx->bit_rate = bitrate_kbps*1024;
m_ctx->width = m_width;
m_ctx->height = m_height;
m_ctx->time_base = { 1, (int)fps };
m_ctx->qmin = 10;
m_ctx->qmax = 35;
m_ctx->gop_size = fps;
m_ctx->max_b_frames = 0;
m_ctx->has_b_frames = false;

m_ctx->codec_id = m_encoder->id;
m_ctx->codec_type = AVMEDIA_TYPE_VIDEO;
m_ctx->pix_fmt = m_h264InputFormat;

AVDictionary *param = nullptr;
av_dict_set(&param, "look_ahead", "0", 0);
av_dict_set(&param, "look_ahead_depth", "8", 0);
av_dict_set(&param, "preset", "veryfast", 0);
av_dict_set(&param, "tune", "zerolatency", 0);

int ret = avcodec_open2(m_ctx, m_encoder, &param);

avformat/matroskaenc : Remove unnecessary avio_tell(), avio_seek()
22 janvier 2020, par Andreas Rheinhardtavformat/matroskaenc : Remove unnecessary avio_tell(), avio_seek()
avio_close_dyn_buf() has a bug : When the write pointer does not point to
the end of the written data when calling it (i.e. when one has performed
a seek back to update already written data), it would not add padding to
the end of the buffer, but to the current position, overwriting other
data ; furthermore the reported size would be wrong (off by the amount of
data it has overwritten with padding).In order not to run into this when updating already written elements or
elements for which size has only been reserved, the Matroska muxer would
first record the current position of the dynamic buffer, then seek to
the desired position, perform the update and seek back to the earlier
position.But now that end_ebml_master_crc32() does not make use of
avio_close_dyn_buf() any more, this is no longer necessary.Signed-off-by : Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
