Issue with creating Video files from Binary files
22 septembre 2022, par user20057686We have a bunch of binary files that represent Video data.
This is how the binary files were created :


- 

- Used MediaRecorder from a React application to capture the browser window.
To capture the screen stream we used (Navigator.)MediaDevices.getDisplayMedia() API
- Each video is recorded for 1-second duration
- This data is then encoded with base64 and sent through a websocket. The server decodes the base64 string and stores the binary data in a file (without any extension)








So we now have a bunch of binary files each containing 1 second worth of video data.


The issue is, we are not able to convert all the binary files back to a single video.

We tried using ffmpeg


copy /b * merged.


ffmpeg -i merged merged.mp4






Basically first merging all the binary files and converting to mp4. It didn't work. The resulting video duration is not equal to the (number_of_files) in seconds.

We also tried converting individual chunks with ffmpeg but we get the below error :


[h264 @ 000001522dc74b80] [error] non-existing PPS 0 referenced
[h264 @ 000001522dc74b80] [error] non-existing PPS 0 referenced
[h264 @ 000001522dc74b80] [error] decode_slice_header error
[h264 @ 000001522dc74b80] [error] no frame !
I can provide the complete logs if needed.

Next thing we tried was to use MoviePy library in Python. We programmatically concatenated the files and saved them as WebM and imported it into MoviePy as a Video.








In all the above approaches, we couldn't get the full video.

FFMPEG Video Multiplexer [closed]
24 janvier, par NaderI am a DirectShow developer, I used to build multiplexers that take 2 video inputs and generate one output, I would then use a video encoder mux to feed it the output + anothrr audio stream to generate the final video output. The multiplexer (DirectShow framework) allows me to process the input video from two sources (for example, adding effects using the two frames).


How can this can be done using FFMPEG ?
