RTSP to HLS conversion with error on some devices
2 septembre 2024, par Wallace KetlerI'm trying to convert, on a node server, RTSP IP camera devices to HLS to run livestreams on the web. The following code works well for some RTSP devices, but for others I encounter problems.


function startLive(rtspUrl, outputDir, id_local, id_camera) {
 return new Promise((resolve, reject) => {
 const processKey = `${id_local}_${id_camera}`;
 if (ffmpegProcesses[processKey]) {
 return reject(new Error('Conversão já está em andamento para esta câmera'));
 }
 
 const process = ffmpeg(rtspUrl)
 .inputOptions([
 '-rtsp_transport', 'tcp',
 '-fflags', 'nobuffer',
 '-max_delay', '1000000',
 '-analyzeduration', '1000000',
 '-probesize', '1000000',
 '-flush_packets', '1',
 '-avioflags', 'direct'
 ])
 .outputOptions([
 '-c:v', 'libx264',
 '-preset', 'ultrafast',
 '-tune', 'zerolatency',
 '-c:a', 'aac',
 '-hls_time', '10',
 '-hls_flags', 'delete_segments',
 '-hls_list_size', '5',
 '-hls_wrap', '5',
 '-strict', '-2'
 ])
 .output(path.join(outputDir, 'stream.m3u8'))
 .on('start', (commandLine) => {
 console.log('Spawned FFmpeg with command: ' + commandLine);
 })
 .on('stderr', (stderrLine) => {
 console.log('FFmpeg stderr: ' + stderrLine);
 })
 .on('end', () => {
 console.log('Conversão concluída');
 delete ffmpegProcesses[processKey]; 
 resolve();
 })
 .on('error', (err, stdout, stderr) => {
 console.error('Erro na conversão', err);
 console.error('FFmpeg stdout:', stdout);
 console.error('FFmpeg stderr:', stderr);
 delete ffmpegProcesses[processKey]; 
 reject(err);
 })
 .run();
 
 ffmpegProcesses[processKey] = process; 
 });
 }


When the conversion succeeds, it continues indefinitely with the logs :


FFmpeg stderr: frame= 61 fps= 48 q=13.0 size=N/A time=00:00:02.03 bitrate=N/A dup=60 drop=0 speed= 1.6x

FFmpeg stderr: frame= 246 fps= 33 q=19.0 size=N/A time=00:00:08.20 bitrate=N/A dup=91 drop=0 speed= 1.1x 


And with the segments saved in the folder configured as output. But for certain devices, after creating the stream.m3u8 file and saving the first segment, the conversion is considered finished and falls into
.on('end'). The error log is as follows :

FFmpeg stderr: frame= 0 fps=0.0 q=0.0 size=N/A time=00:00:01.12 bitrate=N/A speed=2.08x 
FFmpeg stderr: [hls @ 0x55e00dfc4380] Opening 'my_path/stream0.ts' for writing
FFmpeg stderr: [hls @ 0x55e00dfc4380] Opening 'my_path/stream.m3u8.tmp' for writing
FFmpeg stderr: frame= 0 fps=0.0 q=0.0 Lsize=N/A time=00:00:01.37 bitrate=N/A speed= 2.5x 
FFmpeg stderr: video:0kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: unknown
FFmpeg stderr: [aac @ 0x55e00dfff840] Qavg: 65536.000
FFmpeg stderr: 
Conversão concluída


The
muxing overhead: unknownonly appears when the error occurs and the conversion is complete.

I've already tried changing the video and audio encoders, as well as the various input and output parameters of the conversion. I also tried updating ffmpeg (it's already on the latest version, using fluent-ffmpeg,
"fluent-ffmpeg": "^2.1.3",)

I would like to understand why this happens on some devices and how to fix it. Thanks.

I have an application in flask where it streams a camera using ffmpeg, the problem is that I can not display the video from the camera using the GPU [closed]
17 janvier, par RubenI'll put you in context, I am using flask (python) to display a camera in the browser to stream it, for this I use the following Python code :


command = [
 'ffmpeg',
 '-loglevel', 'warning',
 '-rtsp_transport', 'tcp',
 '-i', self.config['url'],
 '-map', '0:v:0', # fuerzo que solo procese el video
 '-vf', f'fps={self.config["fps"]},scale=640:360:force_original_aspect_ratio=decrease',
 '-c:v', 'h264_nvenc', # especificamos que queremos tirar de la gpu de nvidia
 '-preset', 'p7', # ajusta para la maxima calidad/velocidad (p1 mas rapida pero peor calidad - p7 más lento pero mejor calidad)
 '-qp', self.config['quality'], # control de calidad del codificador (0 [mejor calidad] - 51 [peor calidad])
 '-pix_fmt', 'yuv444p', # se mete explicitamente el formato de pixeles
 '-color_range', 'pc',
 '-an', # desactiva el audio
 '-f', 'image2pipe',
 'pipe:1'
] 

self.process = subprocess.Popen(
 command,
 stdout=subprocess.PIPE,
 stderr=subprocess.PIPE,
 bufsize=10**8
)


The problem is that it does not display the video streaming, but it connects correctly to the camera.


On the other hand, It show me the following warnings, which may have something to do with the display, it's probably the second warning that has to do with the pixel format :


DEBUG :main:FFmpeg [camera1] : Guessed Channel Layout for Input Stream #0.1 : mono
DEBUG :main:FFmpeg [camera1] : [swscaler @ 0x560f70b78680] deprecated pixel format used, make sure you did set range correctly


The server has different encodes installed :


DEV.LS h264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 (decoders : h264 h264_v4l2m2m h264_qsv h264_cuvid ) (encoders : libx264 libx264rgb h264_nvenc h264_omx h264_qsv h264_v4l2m2m h264_vaapi nvenc nvenc_h264 )


Y uso el h264_nvenc, tambien el servidor tiene soporte de aceleración de hardware con :


libavutil 56. 70.100 / 56. 70.100
libavcodec 58.134.100 / 58.134.100
libavformat 58. 76.100 / 58. 76.100
libavdevice 58. 13.100 / 58. 13.100
libavfilter 7.110.100 / 7.110.100
libswscale 5. 9.100 / 5. 9.100
libswresample 3. 9.100 / 3. 9.100
libpostproc 55. 9.100 / 55. 9.100
Hardware acceleration methods :
vdpau
cuda
vaapi
qsv
drm
opencl


Between them h264_nvenc uses cuda
