Need to write to a file using fopen in a C++ class for iOS project
2 mai 2014, par Chuck Mc DuranI have a project that uses C++ classes and FFmpeg, I need to use fopen and write a file to the app sandbox, so the code that I need to write in C++ is the equivalent of:
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *docs_dir = [paths objectAtIndex:0];This would me to my app sandbox, where I can pretty much manipulate my files The question is how do I go about writing this code in C++ so that I can use fopen on a file?
This is the method that needs implementation:
int testGrabAndWrite(const char* streamURL, bool decode, const char* filename) { FILE *outfile; int ret; int counter = 0; uint8_t *data; // Pointer to the received audio mem int size; // Size of the received audio buffer outfile = fopen(filename, "w"); if (outfile == NULL) exit(1); // Open the RTP stream if ((ret = openStream(streamURL, decode)) < 0) return ret; // Print out info about the stream found int tmpSampleRate, tmpBitRate, tmpChannels; ret = getStreamInfo(tmpSampleRate, tmpBitRate, tmpChannels); printf("\nSample rate:%d Bit rateL%d Channels:%d\n",tmpSampleRate,tmpBitRate, tmpChannels); // Grab some sample data and write it to file. while (counter < 500) { ret = getStreamData(data, size); fwrite(data, 1, size, outfile); // Write RTP packets, i.e. mp3, to file. printf("Wrote packet %d with size %d which returned %d. ", ++counter, size, ret); } fclose(outfile); closeStream(); return ret; } -
rtmpdump check status by command line
2 mai 2014, par DavidI tried doing rtmpdump -r "rtmp-raw=rtmpe://watch.playfooty.tv/live playpath=nba1569 swfUrl=http://www.playfooty.tv/play/player/player.swf live=1 pageUrl=http://www.playfooty.tv/" But the output it´s like offline always
RTMPDump v2.2e (c) 2010 Andrej Stepanchuk, Howard Chu, The Flvstreamer Team; license: GPL DEBUG: Parsing... WARNING: Unknown protocol! DEBUG: Parsed host : watch.playfooty.tv DEBUG: Parsed app : live playpath=nba1569 swfUrl=http:/ DEBUG: Protocol : RTMP DEBUG: Hostname : watch.playfooty.tv DEBUG: Port : 1935 DEBUG: Playpath : www.playfooty.tv/play/player/player.swf live=1 pageUrl=http://www.playfooty.tv/ DEBUG: tcUrl : rtmp://watch.playfooty.tv:1935/live playpath=nba1569 swfUrl=http:/ DEBUG: app : live playpath=nba1569 swfUrl=http:/ DEBUG: live : no DEBUG: timeout : 30 secI tried a lot of links of a list and seems offline with this command, but When I play it in a software it worked.
Does anyone have an idea how to test if this kind of links are alive or die?
Thanks!

Parsing xml with perl and libXML
2 mai 2014, par user3589690I have an XML file which I would like to parse and use to create an arguments set for ffmpeg encoding.
This is what a dump of the xml looks like:
$VAR1 = { 'profile' => [ { 'enodingParam' => { 'videoFrameRate' => { 'arg' => '-r', 'content' => '25' }, 'audioCodec' => { 'arg' => '-acodec', 'content' => 'libfaac' }, 'videoCodec' => { 'arg' => '-vcodec', 'content' => 'libx264' }, 'videoSize' => { 'arg' => '-s', 'content' => '640x360' }, 'audioBitrate' => { 'arg' => '-ab', 'content' => '96k' }, 'videoGOP' => { 'arg' => '-g', 'content' => '90' }, 'audioRate' => { 'arg' => '-ar', 'content' => '22050' }, 'audioChannels' => { 'arg' => '-ac', 'content' => '2' }, 'videoPreset' => { 'arg' => '-vpre', 'content' => 'slow' }, 'videoBitrate' => { 'arg' => '-b', 'content' => '1200k' } }, 'metadat' => { 'fileContainer' => '.mp4', 'profileName' => 'testpfrof1' } }, { 'enodingParam' => { 'videoFrameRate' => { 'arg' => '-r', 'content' => '25' }, 'audioCodec' => { 'arg' => '-acodec', 'content' => 'libfaac' }, 'videoCodec' => { 'arg' => '-vcodec', 'content' => 'libx264' }, 'videoSize' => { 'arg' => '-s', 'content' => '320x180' }, 'audioBitrate' => { 'arg' => '-ab', 'content' => '96k' }, }, 'videoGOP' => { 'arg' => '-g', 'content' => '90' }, 'audioRate' => { 'arg' => '-ar', 'content' => '22050' }, 'audioChannels' => { 'arg' => '-ac', 'content' => '2' }, 'videoPreset' => { 'arg' => '-vpre', 'content' => 'slow' }, 'videoBitrate' => { 'arg' => '-b', 'content' => '400k' } }, 'metadat' => { 'fileContainer' => '.mp4', 'profileName' => 'testProfile2' } } ] };I would like to use a foreach loop for the encodingparam node/tagname and end up with a string which looks something like this:
-acodec libfaac -vcodec libx264 -s 640x360 -ab 96kI am kind of stuck . This is what I have put together so far:
#!/usr/bin/perl use warnings; use strict; use Data::Dumper; use XML::LibXML; my $filename = "xml/profile.xml"; my $parser = XML::LibXML->new; my $doc = $parser->parse_file($filename) or die "can't parse profile file: $@"; my $root = $doc->documentElement(); my @nodeList = $doc->getElementsByTagName('enodingParam');here is the xml file
<?xml version="1.0"?>testp1 .mp4 libx264 slow 1200k 640 360 640x360 25 90 ab 96k -acodec libfaac 2 "22050" testProfile22 .mp4 libx264 slow 1200k 640 360 640x360 25 90 96k libfaac 2 22050 Modified the pl script to
use warnings; use strict; use Data::Dumper; use XML::LibXML; my $filename = "xml/book.xml"; my $parser = XML::LibXML->new; my @ffmpegargs; my $fileName="filename"; my $doc = $parser->parse_file($filename) or die "can't parse profile file: $@"; my $root = $doc->documentElement(); my @paramList = $doc->getElementsByTagName('enodingParam'); for my $ele (@paramList) { # You then need to iterate over all the children of that node... for my $param ($ele->nonBlankChildNodes()) { my $inparams = " " . $param->getAttribute('arg') . " " . $param->textContent ; push ( @ffmpegargs, $inparams); } my $ffmpeg = join(" ", @ffmpegargs); print "ffmpeg" . $ffmpeg, "\n"; }It is printing out correctly. Now how do i add the following to the string $filename , profileName, containerName (from the metadat node) to the same string so that my final output looks like:
ffmpeg -vcodec libx264 -vpre slow -b 1200k -w 640 -h 360 -s 640x360 filename_profileName_containerNameok tried zooming ue to profile. Not sure how to traverse the child nodes. Tried this. But its nor printing the right values
use warnings; use strict; use Data::Dumper; use XML::LibXML; my $filename = "xml/book.xml"; my $parser = XML::LibXML->new; my @ffmpegargs; my $fileName="filename"; my $doc = $parser->parse_file($filename) or die "can't parse profile file: $@"; my $root = $doc->documentElement(); my @paramList = $doc->getElementsByTagName('profile'); for my $ele (@paramList) { # You then need to iterate over all the children of that node... for my $param ($ele->findnodes('/encodingParam/*')) { my $inparams = " " . $param->getAttribute('arg') . " " . $param->textContent ; push ( @ffmpegargs, $inparams); } my $ffmpeg = join(" ", @ffmpegargs); print "ffmpeg" . $ffmpeg, "\n"; } -
