Need help accessing the key when trying to decrypt .ts files via ffmpeg
4 juillet 2024, par DizI have downloaded all the individual .ts files and the corresponding m3u8 file from a VOD and I now want to merge them together into a single watchable file.
The problem is, that the .ts files are encrypted and don't understand how to access the key.


Here's the beginning of the m3u8 file :


#EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:4
#EXT-X-PLAYLIST-TYPE:EVENT
#EXT-X-MEDIA-SEQUENCE:6484
#EXT-X-KEY:METHOD=AES-128,URI="irvine://aes",KEYFORMATVERSIONS="1",IV=0x1E9ABA2B3C916D47D592D9B1E7674F4B
#EXT-X-PROGRAM-DATE-TIME:2024-05-25T07:24:59.682Z
#EXTINF:4.004,
index_1_6484.ts
#EXT-X-PROGRAM-DATE-TIME:2024-05-25T07:25:03.686Z
#EXTINF:4.004,
index_1_6485.ts
#EXT-X-PROGRAM-DATE-TIME:2024-05-25T07:25:07.690Z
#EXTINF:4.004,
index_1_6486.ts
#EXT-X-PROGRAM-DATE-TIME:2024-05-25T07:25:11.694Z
#EXTINF:4.004,
index_1_6487.ts
...




As far as I understood I only have the initialization vector and I need to access the URI to get the actual key.


I have tried to decrypt the playlist with the following command :


ffmpeg -i index_1.m3u8 -c copy output.ts



But I would always get the following errors :


Unable to open key file irvine://aes
Error when loading first segment 'index_1_6484.ts'
Error opening input: Invalid data found when processing input
Error opening input file index_1.m3u8.
Error opening input files: Invalid data found when processing input



I have also tried just decrypting a single .ts file to start with, with similar results.


ffmpeg -decryption_key 1E9ABA2B3C916D47D592D9B1E7674F4B -i index_1_6484.ts -codec copy index_1_6484_out.ts

Why ffmpeg concat results wrong fps ? How to avoid it ?
29 avril 2024, par JinglongI have several mp4 video files and want to concat there video streams into a new mp4 file. The command I used shows below :


ffmpeg -f concat -safe 0 -i concat.txt -an -c:v copy -y out.mp4



The fps of result does not meet expectations.


For example, there are two input wrote in
concat.txt
:

file temp_result_0.mp4
file temp_result_1.mp4







 file 

duration 

number of frames 

fps 

tbr 







 temp_result_0.mp4 

60.0 

1200 

20 

20 




 temp_result_0.mp4 

0.1 

2 

20 

20 




 out.mp4 

60.1 

1202 

19.97 

20 







The
out.mp4
has correctduration
,nb_frames
but wrongavg_frame_rate
(expecting 20 but get 6010/301).

Inappropriate ioctl for device in zoneminder - zmc_dvideo0
9 juin 2024, par AdamI recently needed to rebuild my zoneminder local camera system, running on an RPi. I switched OS from Debian to Ubuntu and now I'm struggling to get video4linux to decode the video input. The result is either a black or green screen depending on the compression palette I select.


I'm using /dev/video0 as my input.


v4l2-ctl --list-devices

unicam (platform:fe801000.csi):
 /dev/video0
 /dev/media3



In the logs I'm getting :


zmc_dvideo0 10907 ERR Unable to query control: Inappropriate ioctl for device 



I don't understand the function of the /dev/media3 device, presumably created by the bcm2835-v4l2 module. This site suggests that /dev/video0 needs to extract the ioctl from or link in some way to /dev/media3. Perhaps a red herring.


If I select /dev/media3 as the source, I get :


: FAT [zmc_dmedia3] [Failed to query video device: Inappropriate ioctl for device]
: ERR ['zmc -d /dev/media3' exited abnormally, exit status 255]



I'm using


- 

- PAL60 encoding
- YUV422p compression
- 1280 x 720 Capture Resolution

Using ffmpeg from the cli, I get a similar output, resulting in a green display. This happens both with and without the hardware acceleration flag.


sudo -u www-data ffmpeg -f v4l2 -pix_fmt yuyv422 -framerate 30 -video_size 1280x720 -i /dev/video0 -codec:v h264_v4l2m2m video0_out.mp4



I've set debug to 6 in the ZM options - Any clues on troublshooting steps I can take to further understand why the camera stream is not being shown and how to fix it ?
