FFMPEG error with avformat_open_input returning -135
28 avril 2015, par LawfulEvilI have a DLL one of my applications uses to receive video from RTSP cameras. Under the hood, the DLL uses FFMPEG libs from this release zip :
ffmpeg-20141022-git-6dc99fd-win64-shared.7zWe have a wide variety of cameras in house and most of them work just fine. However, on one particular Pelco Model Number : IXE20DN-OCP, I am unable to connect. I tested the camera and rtsp connection string on VLC and it connects to the camera just fine.
I found the connection string here : http://www.ispyconnect.com/man.aspx?n=Pelco
rtsp://IPADDRESS:554/1/stream1Oddly, even if I leave the port off of VLC, it connects, so I’m guessing its the default RTSP port or that VLC tries a variety of things based on your input.
In any case, when I attempt to connect, I get an error from av_format_open_input. It returns a code of -135. When I looked in the error code list I didn’t see that listed. For good measure, I printed out all the errors in error.h just to see what their values were.

DumpErrorCodes - Error Code : AVERROR_HTTP_SERVER_ERROR = -1482175992Nothing even close to -135. I did find this error, sort of on stack overflow, here runtime error when linking ffmpeg libraries in qt creator where the author claims it is a DLL loading problem error. I’m not sure what led him to think that, but I followed the advice and used the dependency walker (http://www.dependencywalker.com/) to checkout what dependencies it thought my DLL needed. It listed a few, but they were already provided in my install package.
To make sure it was picking them up, I manually removed them from the install and observed a radical change in program behavior(that being my DLL didn’t load and start to run at all).
So, I’ve got a bit of init code :
void FfmpegInitialize()
{
av_lockmgr_register(&LockManagerCb);
av_register_all();
LOG_DEBUG0("av_register_all returned\n");
}Then I’ve got my main open connection routine ...
int RTSPConnect(const char *URL, int width, int height, frameReceived callbackFunction)
{
int errCode =0;
if ((errCode = avformat_network_init()) != 0)
{
LOG_ERROR1("avformat_network_init returned error code %d\n", errCode);
}
LOG_DEBUG0("avformat_network_init returned\n");
//Allocate space and setup the the object to be used for storing all info needed for this connection
fContextReadFrame = avformat_alloc_context(); // free'd in the Close method
if (fContextReadFrame == 0)
{
LOG_ERROR1("Unable to set rtsp_transport options. Error code = %d\n", errCode);
return FFMPEG_OPTION_SET_FAILURE;
}
LOG_DEBUG1("avformat_alloc_context returned %p\n", fContextReadFrame);
AVDictionary *opts = 0;
if ((errCode = av_dict_set(&opts, "rtsp_transport", "tcp", 0)) < 0)
{
LOG_ERROR1("Unable to set rtsp_transport options. Error code = %d\n", errCode);
return FFMPEG_OPTION_SET_FAILURE;
}
LOG_DEBUG1("av_dict_set returned %d\n", errCode);
//open rtsp
DumpErrorCodes();
if ((errCode = avformat_open_input(&fContextReadFrame, URL, NULL, &opts)) < 0)
{
LOG_ERROR2("Unable to open avFormat RF inputs. URL = %s, and Error code = %d\n", URL, errCode);
LOG_ERROR2("Error Code %d = %s\n", errCode, errMsg(errCode));
// NOTE context is free'd on failure.
return FFMPEG_FORMAT_OPEN_FAILURE;
}
...To be sure I didn’t misunderstand the error code I printed the error message from ffmpeg but the error isn’t found and my canned error message is returned instead.
My next step was going to be hooking up wireshark on my connection attempt and on the VLC connection attempt and trying to figure out what differences(if any) are causing the problem and what I can do to ffmpeg to make it work. As I said, I’ve got a dozen other cameras in house that use RTSP and they work with my DLL. Some utilize usernames/passwords/etc as well(so I know that isn’t the problem).
Also, my run logs :

RTSPConnect - Error Code -135 = No Error Message AvailableI’m going to move forward with wireshark but would like to know the origin of the -135 error code from ffmpeg. When I look at the code if ’ret’ is getting set to -135, it must be happening as a result of the return code from a helper method and not directly in the avformat_open_input method.
https://www.ffmpeg.org/doxygen/2.5/libavformat_2utils_8c_source.html#l00398
After upgrading to the latest daily ffmpeg build, I get data on wireshark. Real Time Streaming Protocol :
Request: SETUP rtsp://192.168.14.60/stream1/track1 RTSP/1.0\r\n
Method: SETUP
URL: rtsp://192.168.14.60/stream1/track1
Transport: RTP/AVP/TCP;unicast;interleaved=0-1
CSeq: 3\r\n
User-Agent: Lavf56.31.100\r\n
\r\nThe response to that is the first ’error’ that I can detect in the initiation.
Response: RTSP/1.0 461 Unsupported Transport\r\n
Status: 461
CSeq: 3\r\n
Date: Sun, Jan 04 1970 16:03:05 GMT\r\n
\r\nI’m going to guess that... it means the transport we selected was unsupported. I quick check of the code reveals I picked ’tcp’. Looking through the reply to the DESCRIBE command, it appears :
Media Protocol: RTP/AVPFurther, when SETUP is issued by ffmpeg, it specifies :
Transport: RTP/AVP/TCP;unicast;interleaved=0-1I’m going to try, on failure here to pick another transport type and see how that works. Still don’t know where the -135 comes from.

});Issue is that the program needs to be restarted every X minutes so that the list of media will update on it’s own. However, upon a restart, ffmpeg goes crazy and starts to spam a batch window under it’s name repeatedly over and over again without stopping. The only way out of it is to restart my computer.
I’ve tried to use PM2, Forever, Supervisor. Nodemon afaik won’t auto restart.

How do I make my discord bot play music by using youtubedl's search function instead of url ? (Python)
28 septembre 2021, par PypypieYumI want it to search for the video and play it, how can i change the following code to achieve that ? Every time I use the ytsearch function in ytdl, I notice that it only searches for the first word of the title and download it, however, it causes error later on and do nothing.


@commands.command()
 async def play(self, ctx, url):
 if ctx.author.voice is None:
 await ctx.send("You are not in a voice channel!")
 voice_channel = ctx.author.voice.channel
 if ctx.voice_client is None:
 await voice_channel.connect()
 else:
 await ctx.voice_client.move_to(voice_channel)

 ctx.voice_client.stop()
 FFMPEG_OPTIONS = {'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5', 'options': '-vn'}
 YDL_OPTIONS = {'format':"bestaudio", 'default_search':"ytsearch"}
 vc = ctx.voice_client

 with youtube_dl.YoutubeDL(YDL_OPTIONS) as ydl:
 info = ydl.extract_info(url, download=False)
 if 'entries' in info:
 url2 = info["entries"][0]["formats"][0]
 elif 'formats' in info:
 url2 = info["formats"][0]['url']
 source = await discord.FFmpegOpusAudio.from_probe(url2, **FFMPEG_OPTIONS)
 vc.play(source)


And this is the error message :


Ignoring exception in command play:

The above exception was the direct cause of the following exception:
