Thanks, Jim. The purpose of my command is to convert the video file (*.mp4)
into an h264_mp4 container (*.ts), so that, command mediafilesegmenter can
take the *.ts file to convert it into hls format and stream it. Since I
just change a container, I don't really transcode, so I just use -vcodec

Hi, guys,
I installed ffmpeg-2.8.2 on Mac and run in command line:
ffmpeg -i firstTake.mp4 -vcodec copy -acodec copy -vbsf h264_mp4toannexb
firstTake.ts
and get the following result with some errors. For each time running, the
error happens at different time positions. And if I trim the origin

I was going to tell you that your formats were all wrong,
and that you needed h264 and aac
but I checked and hls has no limit on formats.
However, just because you can, doesn't mean you should,
hls implies h264 video, aac audio and 608 or webvtt captions.
May I ask why you would do it your way?
Hello,
Precedence matters in the command line.
With the 2 commands, note that audio input is before video input
./ffmpeg -debug 1 -xerror -f pulse -ar 44100 -ac 2 -channel_layout
stereo -thread_queue_size 1024 -i
alsa_input.pci-_00_14.2.analog-stereo -f v4l2 -channel 1 -video_size
720x576 -pi
