command line - Why does this gstreamer pipeline stall? -

-

यह काम करता है: 

  gst-launch-0.10 \ videotestsrc! Ffmpegcolorspace! 'वीडियो / एक्स-कच्चे-यूयूवी'! mux। \ Audiotestsrc! ऑडियोकॉनवर! 'ऑडियो / एक्स-कच्चे-एट, दर = 44100, चैनल = 1'! mux। \ Avimux name = mux! Filesink location = gst.avi

मैं इसे थोड़ी देर तक चला सकता हूं, उसे मार डाल सकता हूं, और फिर totem gst.avi टोन के साथ एक अच्छा टेस्ट कार्ड प्रदर्शित करता है

हालांकि, 

  gst-launch-0.10 \ filesrc स्थान = MVI_2034.AVI जैसे कुछ और उपयोगी बनाने की कोशिश कर रहा है! डिकोडिन नाम = dec \ dec ! Ffmpegcolorspace! 'वीडियो / एक्स-कच्चे-यूयूवी'! mux। \ Dec ! ऑडियोकॉनवर! 'ऑडियो / एक्स-कच्चे-एट, दर = 44100, चैनल = 1'! mux। \ Avimux name = mux! फाइलसिंक स्थान = gst.avi

यह सिर्फ 

  पाइपलाइन को PAUSED में सेट करना दिखाता है ... पाइपलाइन प्रीलोलिंग है ...

और फिर अनिश्चितकाल के लिए स्टालों।

क्या डिकोडीन रोलिंग के साथ संस्करण प्राप्त करने के लिए चाल है?

अहा ... ये मुझे क्या चाहिए: 

  gst-launch-0.10 \ filesrc स्थान = MVI_2034.AVI! डिकोडिन नाम = dec \ dec ! कतार ! Ffmpegcolorspace! 'वीडियो / एक्स-कच्चे-यूयूवी'! कतार ! mux। \ Dec ! कतार ! ऑडियोकॉनवर! 'ऑडियो / एक्स-कच्चा-एट, चैनल = 1'! ऑडियोरेम्स! 'ऑडियो / एक्स-कच्चा-इंट, दर = 44100'! कतार ! mux। \ Avimux name = mux! फाइलिंग स्थान = gst.avi

कतार तत्वों (दोनों अग्रणी और अनुगामी) महत्वपूर्ण प्रतीत होते हैं।

आगे के प्रयोगों जैसे videoflip या

<प्री> वीडियोरेट! 'वीडियो / एक्स-कच्चे-यूयूवी, फ्रेमरेट = 25/1'

पाइपलाइन के वीडियो भाग में अपेक्षित के रूप में सभी काम करते हैं।

windows - Heroku throws SQLITE3 Read only exception -

-
After I deploy the app to Heroku, I have to run migration scripts and get this error message ... ITES \ padrino \ prophetmargin & gt; Heroku Rack AR: Rack mutated! SQLite3 :: ReadOnlyException: only one try to write database to read: CREATE TABLE "schema_migrations" ( "version" varchar (255) NOT NULL) /disk1/home/slugs/215264_925fd2c_65a3/mnt/.bundle/gems/gems/ padrino-core- is 0.9.11 / lib / padrino-core / cli / rake.rb: 9: in `init ' how can this be? I also tried to run Heroku dbpush SQLite: //db/my-db.db and that did not work Horoku sqlite3 but using postgres does not do. I'm not sure why you are receiving this error, however, as I have used sqlite3 in development and when pushing it into its travel, they do some magic which migrates to postgrads. I'm absolutely sure how Heroku does 'backwash' this database but it seems that this is happening to you because it's the SQLite db file which is obviously due to Heroku's

lex - Building a lexical Analyzer in Java -

-
I am currently learning lexical analysis in compiler design. To know how a lexical analyzer actually works, I am trying to build myself. I am planning to make it in Java The input to the lexical analyzer is a .tex file that is of the following format. \ section {script} {intro} \ section {Scope} arbitrary text \ section {relevance} uncontrolled text \ subdivision (profit) arbitrary text \ subsubsection {in real life} \ subdivision {Ingredient} \ end {document} The output of the lecture may be a table of contents with a page number in another file. 1 Introduction 1 1.1 Scope 1 1.2 Relevance 2 1.2.1 Benefits 2 1.2.1.1 Real life 2 1.2.2 loss 3 I hope that This problem is within the scope of Language Analysis Read the .exe file and check '\' and continue to check whether it is actually on search In the sectioning command is set to indicate whether or not a flag variable is the type of sectioning. I hope the above approach will work for the construction of Lexa

python - rename keys in a dictionary -

-
I want to change the names of keys in a dictionary which are ints, and I need them so that the inputs with key zero They can sort correctly. For example, my keys are like this: '1', '101', '11' and I may need them: '001', '101', '011' What is doing, but I know that there is a better way tmpDict = {} in the ADC for the old: t MpDict ['% 04d'% int (olden)] = addict [oldkey] New controlled = tmpDict You are going wrong about this if you want to draw entries on a line in a specific way, then you have to sort on the extraction. for sorted (D, key = int): print '% s:% R'% (k, d [k]) < / Div>
