ffmpeg stream encoding out produce a stream shows different program on each start
15 octobre 2018, par Ryan PhilipI am using ffmpeg for almost one year, my stream recently started behaving badly.
The lines on ffmpeg screen started running crazy fast when restreaming it, causing more CPU (with no encoding). I have mapped the stream to select only one stream. But the problem is even with mapping I am getting different program each time when it is played.
Also each program it is playing for less than a minute. There is no specific error message showing on ffmpeg screen. Only the output is behaving badly.
I even tried ffmpeg version 3.3, 3.4 and 4.0 with same results.
It has so many resolution streams, so i selected only 33 (video) and 34 (audio), the ones with highest resolution.
ffmpeg -i "http://insourceip/stream.m3u8" -err_detect explode -c copy -map 0:33? -map 0:34? -hls_time 10 -hls_list_size 6 -hls_wrap 10 -start_number 1 out/music.m3u8Please help me with this.
Below is the output : the one after (No longer receiving playlist 8) start running crazy when started.

FFMpeg How to extract individual audio channels from wav/.w64 and insert in .mxf with track tags
11 septembre 2018, par VinceHi my problem is I have 2 .w64 files (extended wav format) each file has 16 mono channels of audio. I want to be able to extract specific channels of audio from each of those .w64 files and insert those channels into an .mxf file as separate single channel mono audio streams and to be additionally able to set the Tag information on those audio streams. I have tried using -map and so on but it seems to take all the channels from the .w64 files and insert a single audio stream of 16 channels. I apologise in advance as I’m very new to ffmpeg and thanks in advance for any advice any of you can offer. This is all specific to command line usage on windows.
All the bestffmpeg -i "D :\Media\AUDIO_0.W64" -i "D :\media\NO_AUDIO.mxf" -c copy -map 0:0:0 -map 0:0:1 -map 0:0:2 -acodec pcm_s24le -map 1:0 "D :\media\out.mxf"

FFmpeg batch file - combine individual set files with randomized selection from another set of files
4 août 2018, par SiampuI need to combine a specific set of files with a randomized selection from another set of files ; for more specific context, voice clips followed by a randomized walky-talky beep. At the moment, I’ve managed to assemble this so far from searching around :
setlocal EnableDelayedExpansion
cd beeps
set n=0
for %%f in (*.*) do (
set /A n+=1
set "file[!n!]=%%f"
)
set /A "rand=(n*%random%)/32768+1"
cd ..
for %%A IN (*.ogg) DO ffmpeg -y -i radio_beep.wav -i "%%A" -i "beeps\!file[%rand%]!" -filter_complex "[0:a:0][1:a:0][2:a:0]concat=n=3:v=0:a=1[outa]" -map "[outa]" "helper\%%A"At the moment, this will only run the randomization once and use that selection for every file. How can I have it do the randomization for each .ogg in the folder, and get that into FFmpeg as an input ?
