मैं पाइथन 2.7 असफल में pyffmpeg स्थापित करने का प्रयास कर रहा हूं। मुझे पायथन 2.6 के लिए एक पैकेज मिला, लेकिन मैं इसे काम नहीं कर सकता। तो, मैं 2.7 के साथ चारों ओर घूम रहा है। मैंने इस साइट पर दूसरों से पिछली पोस्ट देखी है, लेकिन उन्होंने मदद नहीं की है। क्या किसी के पास इसका अनुभव है। आखिरकार, मैं एक wxPython ऐप विकसित करना चाहता हूं जो वीडियो प्रारूपों को परिवर्तित करता है। धन्यवादपायथन के साथ ffmpeg का उपयोग 2.7
कोड है कि मैं अंत में लिखा है कि मेरे लिए काम किया (बहुत मौलिक है, लेकिन यह काम करता है ....):

pyffmpeg वैसे भी एन्कोडिंग कार्यक्षमता प्रदान नहीं करेगा। इसलिए जब मैंने एक कस्टम वीडियो को एवी में बदलने के लिए एक डब्ल्यूएक्स ऐप बनाया, तो मैंने ffmpeg निष्पादन योग्य के साथ संवाद करने के लिए उपप्रोसेसर मॉड्यूल का उपयोग किया। एक स्मार्ट समाधान नहीं है लेकिन यह काम करता है। अन्यथा, [libVLC] (http://wiki.videolan.org/LibVLC) के लिए एक पायथन बाध्यकारी है जो नौकरी कर सकता है। – otterb
ओह। libVLC केवल डिकोडिंग तक ही सीमित है। – otterb
@otterb - मैंने उपप्रोसेसर मॉड्यूल का उपयोग नहीं किया, लेकिन एक समान दृष्टिकोण लिया। मैंने os.system (...) को रोकने और ffmpeg शुरू करने के लिए उपयोग किया, और कमांड लाइन को आदेश पास कर दिया। "एक स्मार्ट समाधान नहीं है, लेकिन यह काम करता है ...." – suffa
