FFmpeg AVFrame Audio Data Modification
5 septembre 2016, par ArlindI’m trying to figure out how FFmpeg saves data in an
AVFrame
after the audio has been decoded.Basically, if I print the data in the
AVFrame->data[]
array I get a number of unsigned 8 bit integers that is the audio in raw format.From what I can understand from the FFmpeg doxygen, the format of the data is expressed in the
enum AVSampleFormat
and there are 2 main categories : interleaved and planar. In the interleaved type, the data is all kept in the first row of theAVFrame->data
array with sizeAVFrame->linesize[0]
while in the planar type each channel of the audio file is kept in a separate row of theAVFrame->data
array and the arrays have as sizeAVFrame->linesize[0]
.Is there a guide/tutorial that explains what do the numbers in the array mean for each of the formats ?

How to do reprocessing H264 data to image/video
3 octobre 2017, par somethingunexpectedI have been working on a project which blows my mind.
First of all, I have an IP camera that streams H264 data. I am able to stream it with its RTSP url via VLC/ffmpeg/python (rtsp ://ip:port/PSIA/Streaming/channels/2 ?videoCodecType=H.264). So, there is nothing to worry about streaming.
However, on the project, camera is connected to the another system. This system gives the H264 data via ethernet to my PC, so camera is not connected directly to the PC.
The system gives the data in every 10 ms at 1000 bytes. For example, if incoming data is 800 bytes, it adds 200 null bytes.What I can do is to extract these null bytes and take the raw data via a socket. For latency, I use thread module so there is no data leakage.
What I gotta do is to turn these raw H264 data to an image sequence or a video that can be displayed via VLC, ffmpeg, Classic Media Player etc.
I preferrebly want to write my code in Python and every operation has to be in real-time. So, any help would be appreciated.
