The old version I used is part of the latest Buster distro for RPI, I 
recompiled to an updated ffmpeg version and tried again, the same message 
appears:
' [video4linux2,v4l2 @ 0x29d5dd0] The driver changed the time per frame from 
1/30 to 117/7013'

I don't know if this makes any difference for your problem but it
is certainly a strong reason not to spend too much time on it.

Re: [FFmpeg-user] Newbie needs help on capture video/audio using ffmpeg on RPI

[Ram Shaffir]

Got some progress, using the command below bypassed the two errors 
('[video4linux2,v4l2 @ 0x2015cd0] Error allocating a packet.' And '/dev/video0: 
Cannot allocate memory') also, CPU is around 25% and recording time is much 
longer now.

However, I get a new problem and other issues; the major problem is that the 
output is "fast forward", I guess due to the:
'[video4linux2,v4l2 @ 0xd4cd70] The driver changed the time per frame from 1/30 
to 117/7013'

And there are two repeating alerts that I'm not sure their severities:
'ALSA buffer xrun'
and
'Non-monotonous DTS in output stream 0:1;'

My latest command is:

You will need to do some more research on your own. May be that a different 
camera, or a different re-coding platform, is needed to fit requirements. 
And what are those requirements? Are they sensible for the application? For 
instance, 60FPS is not needed for most uses. Do you really need HD? We can't 
answer that, nor provide much advice about hardware selection.


Added for the last reply--
If you can't change the camera, and can't change it's settings (can you?), 
then you'll have to find a more powerful computer or change the 
workflow/parameters. (Is there a reason not to capture in the GoPro and 
collect the video later?)


Please remember that this list is about the ffmpeg software, it's not a 
general video processing list.

Hmm... any suggestions on how to make it work? A different HW between the GoPro 
and the PI that does most of the encoding? Something like this: 
https://www.epiphan.com/products/avio-hd/  (this solution does not work with 
the PI according to their support), but maybe something else?

I truly need to find a solution to this, and your support is priceless!! 

Again, many thanks to you all!

You are trying to convert a RAW 1080p @ 60fps (1988671 kb/s) stream to
h.264 504p @ 30fps (2100Kb/s), the raspberry PI *DOES NOT* have the
CPU power and the USB bus cant handle 248.583875 Mbytes/s

Thank you for your reply!

I will try to build an updated ffmpeg with the additional codecs; can you pls 
point me to an updated tutorial on how to do it? Also, The target ffmpeg is for 
the Raspberry PI, can I build the ffmpeg on a stronger linux machine (such as 
AWS machine)?

Is there anything else I need to take into account when building it for the RPI?

Thanks again for your support!
Cheers,
RS

It doesn't look like that's an option, when a card that size lists haswell i5 
as a "system requirement" it's probably not an actual capture card and depends 
on qsv for its advertised encoding performance.
Maybe you could try a build using libv4l2 and usign the v4l2 m2m codec names?

Hi Carl, 

Got some progress ,however, whenever I use the h264_omx I still get low-quality 
video output compared with libx264 (increasing the bitrate didn't do too much), 
my current command is:

ffmpeg -y -f alsa -thread_queue_size 15000 -ac 2 -itsoffset -0.5 -i hw:1,0 -f 
v4l2 -thread_queue_size 15000 -i /dev/video0 -acodec ac3 -ab 51k -s 896x504 -r 
30 -vcodec h264_omx -b:v 1K -pix_fmt yuv420p -f mp4 
/usr/ramDisk/h264_omx.mp4 -loglevel debug 2> /usr/ramDisk/h264_omx.mp4.log

Hi Carl, thank you for your reply!

No, you are not missing anything, I had many many different tests and all were 
with poor results, for this discussion, I pulled one call (its choppy and audio 
out of sync) but I'll call it once with h264_omx and once with libx264:

ffmpeg -f alsa -ac 2 -i hw:1,0 -f v4l2 -i /dev/video0 -acodec ac3 -ab 128k -f 
matroska -s 1280x720 -vcodec libx264 -preset ultrafast -qp 16 
/usr/ramDisk/testsize2.mkv

ffmpeg -f alsa -ac 2 -i hw:1,0 -f v4l2 -i /dev/video0 -acodec ac3 -ab 128k -f 
matroska -s 1280x720 -vcodec h264_omx -preset ultrafast -qp 16 
/usr/ramDisk/testsize2.mkv

the results are here:
h264_omx output: https://dl.dropbox.com/s/sxy43vkmrw46a8u/h264_omx.mkv
libx264 output: https://dl.dropbox.com/s/e0zhkniw74inpza/libx264.mkv

Unless I'm missing it, what is the exact command line you're using and its 
output. Also, how does it behave without using h/w acceleration?

another issue is that when I try to use the hardware acceleration codec
h264_omx I get very low quality comparing to libx264.


Unless I'm missing it, what is the exact command line you're using and its 
output. Also, how does it behave without using h/w acceleration?

[FFmpeg-user] Newbie needs help on capture video/audio using ffmpeg on RPI

[Ram Shaffir]

Hello,

I’m using RPI v4 4G running “Linux raspberrypi 4.19.97-v7l+ #1294 SMP Thu Jan 
30 13:21:14 GMT 2020 armv7l GNU/Linux”, it currently set for 256M GPU memory, 
the Pi is connected to the GoPro camera (Hero 7) HDMI out using Cam 
Link to the Pi’s USB3, the Pi 
recognize the GoPro as a webcam “/dev/video0”; my goal is to capture both audio 
and video feed from the camera’s HDMI out (the camera’s HDMI feed is 
1920x1080@60FPS) the FFmpeg version is “4.1.4-1+rpt7~deb10u1”.

The devices list on the PI is: v4l2-ctl --list-devices
bcm2835-codec-decode (platform:bcm2835-codec):
/dev/video10
/dev/video11
/dev/video12

Cam Link: Cam Link (usb-:01:00.0-2):
/dev/video0
/dev/video1
/// END OF OUTPUT ///

the encoders list installed are: ffmpeg -f v4l2 -list_formats all -i /dev/video0
