I have an MP4 that plays just fine using omxplayer
omxplayer F.mp4
If I use the -i flag, I get the following media information
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'F.mp4':

I'm experimenting with simple streaming into omxplayer, without success. e.g.
cat F.mp4 | omxplayer -o hdmi --no-keys pipe:0
omxplayer prints
Video codec omx-h264 width 640 height 480 profile -99 fps 30.000000
Audio codec aac channels 2 samplerate 44100 bitspersample 16
Subtitle count: 0, state: off, index: 1, delay: 0
It seems to have figured out the write demux and codec to use. But then nothing. No vid or sound. Just sits there without even the courtesy of an error message.
If I add -b then the screen blanks, so omxplayer is definitely able to send that change to the hdmi output
This may seem a bit pointless,but I am trying to understand the streaming mechanism with a view to replacing the cat with nc, or some other mechanism to provide streaming. I want hw accelerated video rendering so I figured omxplayer was the way to go.
Tried --genlog and it generated an omplayer.log as shown below, but I can't interpret it. Any ideas?
I'm running a model 1 rpi (2012 with 512K, medium overclock)

i deployed moon aerokube on my k8s cluster, i enabled vnc option on my code, but i am unable to see the test execution on the VNC in question, and i got the following error :
I would like to know why ?
in addtion, i will give the logs of each container of the pod related to the session lanched by my program:

07/10/2022 11:58:39 Most compositing window managers like 'compiz' or 'beryl'
07/10/2022 11:58:39 cause X DAMAGE to fail, and so you may not see any screen

07/10/2022 11:58:39 Wireframing: -wireframe mode is in effect for window moves.
07/10/2022 11:58:39 If this yields undesired behavior (poor response, painting
07/10/2022 11:58:39 errors, etc) it may be disabled:
07/10/2022 11:58:39 - use '-nowf' to disable wireframing completely.
07/10/2022 11:58:39 - use '-nowcr' to disable the Copy Rectangle after the
07/10/2022 11:58:39 moved window is released in the new position.

07/10/2022 11:58:39 (induced by either user keystroke or mouse input).
07/10/2022 11:58:39 If this yields undesired behavior (poor response, painting

07/10/2022 11:58:39 If this makes the key mapping worse you can
07/10/2022 11:58:39 disable it with the "-noxkb" option.
07/10/2022 11:58:39 Also, remember "-remap DEAD" for accenting characters.

============================
I have to change the image of x-server container to aerokube/xvfb-server
I want to stream microphone audio from a raspberry pi (3) via VLC. The microphone is a respeaker with 4 channels - maybe this is causing the issues?
The hardware is detected properly:
pi#raspberrypi:~ $ arecord -l
**** List of CAPTURE Hardware Devices ****
card 2: seeed4micvoicec [seeed-4mic-voicecard], device 0: bcm2835-i2s-ac10x-codec0 ac10x-codec0-0 [bcm2835-i2s-ac10x-codec0 ac10x-codec0-0]
Subdevices: 1/1
Subdevice #0: subdevice #0
Also creating a test record accessing the hw direcly works fine
pi#raspberrypi:~ $ arecord -D hw:2,0 -d 3 -f S32_LE test.wav -c 4
Recording WAVE 'test.wav' : Signed 32 bit Little Endian, Rate 8000 Hz, Channels 4
Same as with plughw:
pi#raspberrypi:~ $ arecord -D plughw:2,0 -d 3 test.wav -c 4
Recording WAVE 'test.wav' : Unsigned 8 bit, Rate 8000 Hz, Channels 4
Howver, trying to stream via VLC with
cvlc -vvv alsa://plughw:2,0 --sout '#transcode{acodec=mp3,ab=128}:rtp{mux=ts,dst=192.168.0.135,sdp=sap}'
does not work and gives: (short, full console output below)
[736060c0] access_alsa demux error: cannot restrict channels count: Invalid argument
[736060c0] main demux debug: no access_demux modules matched
[73617f90] main stream debug: creating access: alsa://plughw:2,0

[73617f90] main stream debug: no access modules matched
[73500668] main input error: Your input can't be opened
What is the right command? Just adding channels=2 or something similar did not work.
Is there maybe another good approach to stream "live" audio from a raspberry?
full output:
pi#raspberrypi:~ $ cvlc -vvv alsa://plughw:2,0 --sout '#transcode{acodec=mp3,ab=128,channels=4}:rtp{mux=ts,dst=192.168.0.135,sdp=sap}'

But whatever setting i try the video ends up very laggy and the duration ends up much longer than the original file, even when I play it through VLC. It is a little hard to explain so I will provide a sample file here with the result after the conversion:
https://drive.google.com/file/d/1ADPF2POSnBCiJkgMES2vOn2wznyBst6W/view?usp=sharing
Is it something wrong with the file or with ffmpeg itself and how do I solve it?
Firstly I tried this command:
ffmpeg -i "G:\test\test.ts" -map 0:0 -map 0:1 -vcodec libx265 -crf 23 -filter:v yadif=1 -acodec ac3 -ab 384k "C:\Users\User name\Videos\test.mkv"
And then I tried this with the same result:
ffmpeg -i "G:\test\test.ts" -map 0:0 -map 0:1 -vcodec copy -acodec copy "C:\Users\User name\Videos\test.mkv"
The sample file is converted with the first command.
I am batch converting lots of songs into shorter "Advert" songs for SHOUTcast and to be recognised as adverts by the server. The song must have ":Advert" for both the title and the artist metadata tags. When I use the following command:
ffmpeg -i "$i" -c copy -vn -map_metadata -1 -metadata title=":Advert" -metadata artist=":Advert" -t 120 "adverts/ADVERT_$i"
I would expect it to output the song with only ":Advert" as title and artist metadata but when I import it into the radio playout software (using ID3 1.x tagging) the metadata has not copied across and is therefore lost. Output from ffmpeg:

I believe this is happening because the tag names are different (e.g. title should be title, but is TIT2 when output. Please could someone specify how I could ensure that the metadata is encoded in the ID3 1.x format so that it is readable by the radio playout software. Many thanks.
FFmpeg, by default, writes only ID3v2.4 tags. ID3v1 has to be specified for writing.
Use
ffmpeg -i "$i" -c copy -vn -write_id3v1 true -map_metadata -1 -metadata title=":Advert" -metadata artist=":Advert" -t 120 "adverts/ADVERT_$i"
For an app I'm developing, I need avconv to stream from a link for a specified length of time. I've tried using -timelimit to no avail. What am I doing wrong? Is there a better way to do this? Why doesn't -timelimit work?
See, for example, the call below, which runs until terminated with ctrl-c.
stack#ThinkPad:~/app_dev$ avconv -timelimit 30 -i http://br-mp3-bayern2sued-m.akacast.akamaistream.net/7/731/256282/v1/gnl.akacast.akamaistream.net/br_mp3_bayern2sued_m stack_test.mp3

-t and -timelimit are different. More importantly, you need to use -t as an output option, not as an input option. Updating your example, the following should work (tested on ffmpeg).
ffmpeg -i http://br-mp3-bayern2sued-m.akacast.akamaistream.net/7/731/256282/v1/gnl.akacast.akamaistream.net/br_mp3_bayern2sued_m -t 30 stack_test.mp3
